4 Introduction The PI switchgear is based on a modular single-busbar system with truck-type HVX circuit-breaker. PI supplementary panels with fixed switch disconnectors L-TRI or vacuum contactors (up to 7.2 kv) and billing metering panels complete the range. PI can be completed with the switch disconnector panels PN. The switchgear panels feature a functional front design, simple operation and a long, maintenance-free service life. PI has been designed for a high degree of functionality, straightforward planning and configuration, as well as low investment and operating costs. Existing switchgear can generally be extended on both sides of the system. Due to the modular design of the switchgear assembly, individual panels can be exchanged. By inserting an insulating protection plate whilst the panel door remains closed, the panels are easily and independently accessible for checking purposes, inspections and assembly work with the busbars still energized. The design and the equipment variants offer an economically efficient adaptation to the requirements of the operating company. General description PI in detail The air-insulated circuit-breaker switchgear units PI with rated voltages up to 24 kv rated currents up to 1250 A rated peak withstand currents up to 63 ka rated short-time currents up to 25 ka 1s are primarily used for application in switchgear of power supply companies industry and infrastructure.

5 Introduction (contd.) The prefabricated and type-tested switchgear PI 100 is available for rated voltages from 12 kv to 24 kv. It is designed for a high degree of functionality, straightforward planning and configuration, as well as low investment and operating costs. The outstanding features are a very long maintenance-free service life, simple user guidance and trouble-free disposal at the end of the service life. Features Air-insulated Prefabricated and type-tested User-friendly Economically efficient operation Long maintenance-free service life Completely metal-enclosed Loss of service continuity category LSC 2A Compartmentalization class PI Double sheet-steel cladding between panels. Should an internal fault occur, it is limited to the largest possible extent to the faulty panel.

7 Mechanical design (contd.) Switchgear panel The air-insulated panel PI features metal covers made of hot-galvanized, profiled sheet steel on all sides and is built as a riveted composite structure. Due to the closed design - including the sides - the assembly of the panels creates configured switchgear. The double sheet-metal cladding with an additional air gap of 8 mm between the individual panels ensures a very high degree of operational reliability. This advantage is of especial significance with regard to the high degree of flexibility and a quick recovery in the improbable event of an internal arc, as the panels can be dismantled from and remounted into the switchgear assembly easily. The panel door is a userfriendly lifting door. The door hinges can be mounted on the left or right side. Subsequent retrofitting is quick and simple. Final assembly, panels PI Due to the multiple interlocking on both sides of the panel and due to additional overlapping of the door at the top and bottom of the panel, a high degree of mechanical stability is achieved, ensuring maximum operator safety in the event of an internal fault. The busbar sections are spliced from panel to panel and are held by a bushing plate with bushings.

8 Mechanical design (contd.) Low-voltage cabinet (optional with digital panel control unit) Corrosion protection Especially pre-treated hotgalvanized sheet-steel plates ensure optimum protection against corrosion throughout the switchgear s entire service life. All the other metal parts have also been treated to prevent corrosion. In addition, the doors are coated, using the RAL 7044 paint. Other colours are available on request. Low-voltage cabinet A separate low-voltage cabinet is located in the upper panel area. It is metal-enclosed and separated from the highvoltage compartment by means of double sheet-metal plates. Thus, the panels can be introduced individually into the switchgear room. If spare panels are to be completed or retrofitting is to be performed (e.g. in case of process changes), the entire group of low-voltage cabinets can be replaced. The low-voltage cabinet is an independent component with mechanical and electrical interfaces to the panel and can be adapted gradually to the requirements of extension. Even after the low-voltage cabinet has been removed, the panel remains completely metal-enclosed. Measuring instruments, control elements, protection relays or bay computers can be installed in the torsion-resistant door of the low-voltage cabinet. An optional mimic diagram with control and display elements for the switching devices can be implemented in the door of the low-voltage cabinet. The low-voltage cabinets are available in the heights 730 mm, and the depths 2351) mm and 335 mm. Secondary lines The secondary lines in the panel are routed in a sufficiently dimensioned, covered cable duct. There is a cut-out in the bottom of the duct for routing the cables into and out of the unit. The cables between the panel and the low-voltage cabinet are plug-in type. Cut-outs are provided for the ring mains between the lowvoltage cabinets. If required, these cables are placed on one side in the factory, and the opposite side is marked. Cable duct for secondary lines PI 8 PI 100 E

9 Mechanical design (contd.) Cable connection area The cable connection area offers ample space for the installation of plastic cables. Bore-holes for M10 / M12 securing bolts are provided in the cable connection links. Up to 2 x 3 cable boxes can be connected. The cable supports (C profile) are adjustable in height and depth. Current transformers Current transformers DIN part 8 (slim design) are used in the outgoing feeder of the circuit-breaker units. The protection and measuring cores of all 3 conductors are integrated in one transformer. On request, one core can be designed as calibrated core for billing metering. Cable connection area with current transformer and earthing switch Cable connection area - circuit-breaker panel 12 kv PI 104 optionally with base plate divided in the factory and cable supports Voltage transformers Voltage transformers with dimensions according to DIN part 9 (slim design) are used in outgoing feeders, or are utilized in a top-mounted box as busbar voltage transformers. On request, the voltage transformers can be used with a calibrated winding for billing metering. Insulating protection plate Whilst performing work in the panel outgoing feeder block, the energized busbar area can be covered by an insulating protection plate, which is inserted from the outside, to prevent inadmissible contact with live parts. The insulating protection plate is inserted while the door remains closed, thus offering the user a high degree of safety. The LSC and compartmentalization class in acc. with IEC /EN is LSC 2A-PI. Interlocking and coding Safe operation of the switchgear is ensured by complying with the locking conditions in accordance with IEC / EN All panels include a mechanical feature which ensures the interlocking of the truck against the earthing switch, provided that such a switch has been installed. Electro-mechanical interlocks are available for busbar earthing switches. Further mechanical and electrical interlocks are available upon request. If different rated currents are required within one switchgear for the circuit-breaker trucks, codes are provided to prevent circuit-breakers with incorrect rated currents from being racked in.

10 Mechanical design (contd.) Switching devices Due to our in-house development and production, both components - the switching device and panel - are ideally combined to form a functional unit. Vacuum circuit-breaker A truck-type HVX vacuum circuit-breaker is used in the PI panel. It is characterized by compact dimensions, good operator guidance and a modern functional industrial design. The circuit-breaker drive mechanism is available in two basic models, i.e. as manual spring mechanism or as motorized spring mechanism. The truck can be equipped optionally with a motor-operated drive mechanism. The motor-operated drive mechanisms are integrated in the circuit- breaker. Switch disconnector In accordance with the electrical requirements, the proven fixed-type switch disconnector L-TRI 5 can also be used in the PI panel. Earthing switches, earthing devices In the circuit-breaker panel, the make-proof earthing switch is integrated in the outgoing feeder. The earthing switch can be actuated by a detachable lever or, optionally, by a motoroperated drive mechanism. In the switch disconnector panel, the earthing switch is mounted on the switch disconnector. Vacuum circuit-breaker HVX on trolley Earthing of the busbar can be realized by means of an earthing switch in the top-mounted box, or by a hand-actuated earthing device. As an alternative to the earthing switch, conventional earthing is also possible by using earthing devices with phase terminal studs and earthing reference points. Drive mechanisms for switch disconnectors and earthing switches In combination with the PI switchgear, a narrow, compact, easy-to-handle and userfriendly double-linkage drive mechanism has been developed. The drive mechanism is used for actuation of the switch disconnector and the earthing switch. On request, this manual drive mechanism can be equipped with a motoroperated drive mechanism. Vacuum contactors For applications involving a large number of operations, e.g. in motors or pumps, vacuum contactor panels PI up to 12 kv can be mounted. Drive mechanism for switch disconnector and earthing switch Actuation of earthing switch HVX in disconnected position 10 PI 100 E

11 Mechanical design (contd.) Auxiliary switches The electrical signalling of the test, open and service position of the circuit-breaker truck is effected by 4- or 8-pole auxiliary switches. The switch disconnector and the earthing switch can be equipped with the HS 3 auxiliary switch. Both 4- and 6-pole auxiliary switches are available. For certain dimensions (pole center spacing in conjunction with the panel width), 10-pole auxiliary switches can also be applied. In the factory, the auxiliary switches are alternately assigned break and make contacts. Please bear in mind that the contacts are preassigned when a shunt opening release is used for resetting a coil current. Due to the switching capacity of the auxiliary switch, electrical components can be controlled directly. For characteristic data regarding the switching capacity, please refer to the current Switch Disconnector Selection List for L-TRI 5. If a switch disconnector with an opening energy storage mechanism is applied together with a release via h.v.h.r.c. fuse link, tripping, as an option, can be signalled by attaching an additional MSKM signalling switch. Auxiliary switches with goldplated contacts are available on request for use under challenging ambient conditions. Auxiliary switch attachment, type HS 3 Signalling switch, type MSKM for fuse tripped signalling Voltage testing systems (optional) The system voltage or the zero voltage state of the outgoing feeders is detected via a separate voltage detection system according to IEC Socket-contacts for the indicator units are located on the panel front. Capacitive voltage presence indicating systems of all the approved manufacturers can be used. Comply with the manufacturer s Operating Manual of the voltage indicators used. All three phases L1, L2 and L3 must always be checked together. Non-used socket-contacts must be closed using a cap. Voltage indicator (optional) (Type HR-ST, Horstmann GmbH) Pluggable voltage detection system in acc. with IEC (option) PI 100 E 11

12 Mechanical design (contd.) Integrated voltage detection system IVIS (option) IVIS display (optional) IVIS is an integrated voltage detecting system with an integrated display unit used to determine zero voltage/mains voltage according to IEC The IVIS system has been designed for maximum operating reliability. It does not require supply from an external source. It features climateproof encapsulated electronics and is maintenance-free, due to permanent monitoring of the indication thresholds. Flash arrow symbols on the indicators display the mains voltage still existing within the defined response thresholds. The IVIS system does not require the electrical repeat tests common for voltage detection systems. Optionally, the integrated voltage detecting system, type CAPDIS-S1+ (Kries) can also be used. Phase comparator (optional) With IVIS, phase comparison can be performed by means of the phase comparator MS 100. Voltage Detecting System, type CAPDIS-S1+, manufacturer: Kries (optional) Phase comparator for HR system (optional), type ORION 3,0; manufacturer: Horstmann GmbH) Phase comparator MS 100 (optional) Capacitive divider-insulators Examples: Phase comparison using the MS 100 on a mediumvoltage switchgear Post insulator with capacitive pick-off Examples: Short-circuit indicator, type ALPHA M As an option, the rack-in contacts for the circuit-breaker on the panel end and/or the applied switch disconnector L-TRI 5 can be equipped with capacitive divider-insulators. Together with the recommended system components, safe isolation from supply and phase coincidence are verified by integrated or non-integrated voltage detection systems according to IEC The electrical characteristics and property classes of the capacitive divider-insulators correspond with conventional insulators. They can be connected to high-resistance and low-resistance systems. The divider-insulators can be inserted on the busbar as well as on the outgoing feeder end. The SCHNEIDER standard is the high-resistance HR system, IEC , for non-integrated voltage detection systems in PI 100 switchgear. Short-circuit indicator Short-circuit indicators are used for narrowing down the fault location in a medium-voltage network and can be used in the switch disconnector panels PI 100 on request. Fault currents are detected separately for the conductors L1, L2 and L3, with the corresponding indication depending on the system. On request, various types of short-circuit indicators can be installed. Surge arrestors PI 100 panels enable installation of surge arresters in the outgoing feeder area. Type and installation on request. 12 PI 100 E

13 Mechanical design (contd.) Availability The air-insulated circuit-breaker switchgear PI is a modular system. Due to the double sheet-steel cladding between the panels, the switchgear configuration can be extended in no time at all - for example to enhance the system. Maintenance work is generally limited to simple lubrication operations on the movable components of the switching devices. Should the exceptional case of an internal electrical fault occur, the fault is limited largely to the affected panel, due to the highly efficient double sheet-metal cladding (between panels and at the ends of the switchgear) and due to the pressure- and gas-proof bushings in the busbar area (always included in the scope of supply) (depending on the intensity and the duration of the arc fault current). The panel can be replaced almost immediately. These advantages ensure a high availability of the switchgear type PI. PI 100 E 13

14 Environmentally compatible design The switchgear PI 100 satisfies to a high degree the ecological requirements in view of environmental protection thanks to optimization of material and energy consumption during manufacture compliance with all ecological requirements during its service life the use of recyclable materials for the re-use or efficient disposal at the end of its service life. Our design directives regarding environmentally compatible design specify the use of materials which are easily recyclable and can be disassembled. The metals which make up approx. 90% of the switchgear are easily recyclable. At the end of their service life, they are recycled 100 % in the form of homogenous materials. Plastics can also be recycled. Thermosetting i.e. non-melting plastics can be comminuted and reused as fillers in other plastic components; thermoplastic - i.e. melting - materials can be recycled in the form of homogenous material. This means that the material is conserved, melted down and used for the construction of new durable parts. To ensure efficient and environmentally compatible disassembly and assignment of materials by the experts in charge of recycling or disposal, the switchgear s plastic components have been identified accordingly. Moreover, material and utilization data sheets are available to provide the customer with an overview of the materials used, and the disposal company with important information regarding the recycling process. Thus, the materials used for our products can be reused 100 %. This represents a major contribution towards saving primary energy and material resources. All materials were selected and developed so that e.g. in case of fire within buildings, affected switchgear only have a minor influence on the fire load (heat development, pollutants in the emissions). Another important ecological aspect is the longevity of our products (30 to 40 years), which is an extremely long service life compared to other capital goods. Furthermore, the switchgear units have been designed so as to require little maintenance which would in turn use up energy and material, and so as to enable straightforward replacement of part components, e.g. if new controllers have been developed on the market (upgrading).

17 Standards Regulations, provisions and standards (contd.) Operator safety and classification The loss of service continuity category in IEC and EN refers to the classification of the switchgear functions in conjunction with the uninterruptible power supply during access to one of the switchgear compartments. The classification features comprise the following aspects: Types of compartments in view of accessibility Compartments accessible to operating companies Compartments accessible via interlock control Compartments accessible depending on process Features Opening does not require any tools - interlock only permits access if high-voltage com-ponents have been earthed in zero-voltage condition. Opening does not require any tools - interlock facili-ties must be combined with the work instructions of the operating company to enable access only if high-voltage components are earthed and completely isolated from the power supply (zero voltage). The above-mentioned standards contain definitions of certain loss of service continuity categories of the switchgear during access to a compartment. Such access may be necessary, e.g. in case of inspection or maintenance work, or for work in general. Switchgear categories. Loss of service continuity categories on opening accessible compartments LSC2 LSC2A Features Busbars and other switchgear panels may be energized Switchgear categories as regards the type ofpartition between energized components andan opened, accessible compartment (compartmentalization class) PI Features Discontinuity covered by insulating material in metallic partitions/shutters between live components and the open switchgear compartment The switch-disconnector switchgear units PI feature loss of service continuity category LSC2A-PI. LSC2A means: In case access to a part of one switchgear panel is required, the other panels of the switchgear may continue to operate. The busbars may remain energized. Protection between the live busbar and the open switchgear compartment is achieved by inserting an insulating protection plate into the panel. This is a temporarily inserted partition within the meaning of standards IEC and DIN EN Al-though all partitions are made of metal, the compartmentalization class is PI, as the inserted plate consists of insulating material. The compartment of the PI switchgear is accessible using a double-bit key, depending on the appropriate tools. It should not be accessible for normal operation but only for cable tests or other work to be performed. PI 100 E 17

18 Standards Regulations, provisions and standards (contd.) Qualification of switchgear regarding hazards in case of internal arcs during normal operation IAC classification Features The internal arc classification IAC refers to the effect of internal excess pressure on covers, doors, inspection glasses, vents etc. Moreover, thermal effects of the internal arc on the enclosure or its root on the enclosure and escaping hot gases and incandescent particles are taken into consideration. The successful IAC classification is to provide, in case of an internal arc, a verified operator safety level approaching that of switchgear under normal operating conditions. Internal faults causing internal arcs The PI switchgear has been designed for a very low probability of internal arcs during its entire service life. IEC and EN point out that faults within an enclosure, e.g. due to damage, extraordinary operating conditions or operating errors, cannot be ruled out completely and may give rise to an internal arc. For this reason, the switchgear must provide the operator with a very good degree of protection. Operator safety is achieved, in accordance with the switchgear standard, by reducing the hazard to a tolerable level. In accordance with ISO / IEC Guideline 51, sect. 5 (Safety concept), this hazard consists both of the probability of the occurrence and of the severity of the damage. With the PI switchgear, all imaginable and preventive measures in acc. with IEC and EN Table 2 Locations of defects, causes and examples for measures reducing the probability of internal arcs - have been implemented ideally by design. To ensure maximum protection of persons in case of an internal arc, the above-mentioned standard recommends further measures to limit the external consequences. These measures, e.g. pressure relief devices and all operations exclusively with the front closed, have been implemented systematically in the PI switchgear series. Planning engineers and operating companies alike can use, in accordance with IEC and EN , the Guideline for selection of suitable switchgear as regards internal arcs : In case of a negligible risk: metal-enclosed switchgear with internal arc classification not required. If the risk is regarded as considerable: only metal-enclosed switchgear with internal arc qualification IAC should be used. In making this decision, planning engineers and operating companies should apply the procedure for selection of suitable switchgear in accordance with ISO / IEC Guide 51, sect. 6. This procedure implies that the operator must contribute to reducing the risk. 18 PI 100 E

19 Standards Regulations, provisions and standards (contd.) Installation of switchgear units with IAC qualification IEC / EN requests minimum admissible conditions for installation of switchgear with IAC qualiication. The standard implies the following specifications for IAC qualification testing: Minimum clearance 600 (±100) mm from the panel top to the ceiling. An additional test with smaller clearances to the ceiling is admissible as a supplementary test to obtain information on the installation conditions. Design for internal fault testing with indicators The total panel height of the PI switchgear with IAC qualification amounts to 2225 mm. The IAC qualification test has been performed successfully with the lowest ceiling height of 2400 mm. The side wall and the rear wall of the building must be at a clearance of (100 ± 30) mm in each case to the sides or to the rear of the switchgear panels. A smaller clearance can be selected in accordance with the standard if no permanent deformation encumbers or restricts the sides or rear wall of the building. The instructions and information regarding minimum room heights and wall clearances for the PI switchgear are contained in this System Configuration; compliance with these is mandatory for switchgear with IAC qualification. These are the minimum admissible conditions in accordance with the standard. Each installation condition which is not as strict and / or provides for more space, in accordance with IEC / EN , is viewed as having been covered by the IAC qualification test. Internal fault in action Internal arc classification The internal arc classification IAC provides a verified level of operator safety in the immediate vicinity of the switchgear under normal operating conditions: The internal arc classification is an option in accordance with IEC and EN It refers to the effect of internal excess pressure on covers, doors, inspection glasses, vents etc. Moreover, the thermal effects of the internal arc and its root points on the enclosure and escaping hot gases or incandescent particles are taken into account. The PI switchgear series is available in the design with internal arc classification IAC. In the IAC design, it has been provided for accessibility degree A, i.e. the places of installation of the PI switchgear units are enclosed electrical operating areas which are only accessible to authorized staff. The internal arc classification IAC for the PI series refers to the following sides of the switchgear enclosure: the front side (operator s side) the sides The IAC classification has been verified successfully for the PI switchgear: 12 kv PI panels up to 25 ka, Arc duration 1 second Qualification IAC AFL Internal arc 25 ka, 1s 24 kv PI panels up to 20 ka, Arc duration 1 second Qualification IAC AFL Internal arc 20 ka, 1s PI 100 E 19

20 Standards Regulations, provisions and standards (contd.) Regarding the successful internal arc classification IAC, the following criteria have been complied with: Criterion 1 Correctly secured doors and covers have not opened. Criterion 2 Within the specified test duration, the enclosure has not been torn open and no parts have been hurled away. Criterion 3 No holes have occurred in the accessible sides (front control panel and switchgear sides). Criterion 4 The horizontal and vertical indicators have not been set alight due to the effect of the hot gas. Criterion 5 The ground connection of the enclosure has remained effective. 20 PI 100 E

24 Electrical supplementary modules (contd.) Motor drive All the switch-disconnectors of the L-TRI 5 series and the earthing switches used in the PI switchgear can also be equipped with a motoroperated drive mechanism. The motor-operated drive mechanism is connected to the drive disc of the manual drive mechanism via a mechanical coupling. This coupling ensures that, in case of operating voltage loss, manual emergency operation of the switching device is possible with the door closed.

33 Design data (contd.) Installation of the switchgear panels The switchgear compartment must comply with the requirements acc. to DIN VDE 0101 and HD 637 S1 and with the floor evenness / tolerance data acc. to DIN During the overall planning, the operating company must check whether the requirements on site relating to the switchgear (cable ducts, bushings, floor quality etc.) are met. Should it not be possible to fulfil the requirements regarding floor quality, we recommend installation of a base frame. To fasten the panel to the floor or to the base frame, at least 2 diagonal screw fastenings are required. The panels are designed for wall mounting. For a different mounting arrangement, please contact the manufacturer. End plate The switchgear units are provided with an end plate each for both ends.

37 Shipping instructions Transporting the panels Make sure that the transported units do not slip or tilt during transport of the switchgear. When storing switchgear, observe the admissible conditions for operation. Condensation is not admissible. The individual panels are delivered on pallets. Taking all the safety measures which have to be taken to protect persons and the transported equipment into consideration, transport can be performed by crane, forklift truck or elevating truck. In connection with transport via crane, the crane mounting harness must be hooked into the jack rings of the individual panels or of the switchgear. The angle (upper edge of the panel - transport rope) must be > 60. Should there be no other possibility, transportation on a level surface can also be performed on transport rollers. However, all necessary safety measures must be taken into account. For further information, please refer to the applicable operating and assembly instructions.
