35 5. Design and operation

36 5. Design 5.. Indoor Switching Module The VCB main component is the innovative Tavrida Electric Indoor Switching Module. Tavrida Electric has simplified the mechanical structure of the switching module to the greatest possible extent. It uses three single-coil magnetic actuators, one per pole. All switching elements are assembled along a single axis. All mechanical operations are therefore direct and linear. Three actuators are installed in a steel frame and mechanically linked by a synchronizing shaft. This design eliminates failure modes caused by components in conventional technology such as gears, charging motors, and trip / closing coils. Tavrida Electric manufactures vacuum interrupters that combine small dimensions with an extraordinarily long mechanical and electrical lifespan. The use of a specially designed axial magnetic field distribution provides even current density distribution over the contact surface and consequently a substantial improvement of vacuum interrupting performance. The result is up to 50,000 CO cycles at rated current or up to 50 O-CO cycles at maximum short-circuit breaking current without replacing or adjusting any parts of the circuit breaker. Tavrida Electric Vacuum Circuit Breakers are completely maintenance free over a total life expectancy of at least 30 years. 5.. Control Module Tavrida Electric Control modules provide the following advantages: Low power consumption A low energy level required to close or trip the ISM, no energy consumption by the ISM in its closed or open state and optimization of CM electrical diagrams leads to low CM power consumption - no more than 4 Watts during CM capacitors charging and no more than 7 Watts in standby mode. Optimal ISM control One CM can be applied to several different ISM types. The CM is programmed for use with a particular ISM type. The result is optimal ISM close and trip through a wide range of temperatures. Self-diagnostic functionality The CM has an internal self-diagnostic system that monitors ISM connection, power supply level and internal states of the CM. As a result, the CM can indicate issues by means of LEDs and built-in relays. The malfunction types are indicated by the number of corresponding LED blinks. Wiring optimization The CM controls the ISM main contact state via the same circuit used to close or trip the ISM. Therefore, only one circuit connection between ISM and CM is required. The CM can provide external circuits with information about ISM main contacts state by means of built in relays, which simplifies the switchgear secondary wiring significantly. Position indication of ISM provided by CM can be incorrect, in case CM is not operable due to absence of auxiliary supply. The relay keeps its state after CM power supply disconnection. Compact dimensions and small weight of CM The compact size and weight of the CM (90x65x45 mm, kg) simplifies the installation. The aluminum housing of the CM provides a high EMC level (Table 6). 36

Tavrida Electric offers several kits to ensure that external bus bar connection will not reduce the insulation level of the ISM. CBkit_Ins_3 To comply with the rated impulse withstand voltage of 5 kv according to IEC 67- it is recommended to cover the top connections of ISM5_LD_ and ISM5_LD_3 with insulation kit CBkit_Ins_3. The arrangement is shown below. If the insulation cap set is not used, compliance with the rated insulation level must be verified by a dielectric test. Not applicable for ISM5_LD_. CBkit_Ins_4 To comply with the rated impulse withstand voltage of 95 kv according to IEC 67- it is recommended to cover the terminals of ISM5_MD_ with insulation kit CBkit_Ins_4. The arrangement is shown below. If the insulation cap set is not used, compliance with the rated insulation level must be verified by a dielectric test. CBkit_Shell5_ This kit is used to provide 95 kv BIL level between terminals of the ISM5_Shell_. The external air insulation can withstand 75 kv BIL. The ISM5_Shell_(50_L) requires CBkit_Shell5_ for 75 kv BIL. CBkit_Shell5_ also includes round copper bars and screws for flat bars connection to the ISM5_Shell_ terminals. CBkit_Shell5_ has two sets of bolts with different lengths, selection of their usage depends on the number of bars connected to ISM terminals - single or double bars. CBkit_LD5_ and CBkit_LD5_3 Kits CBkit_LD5_ and CBkit_LD5_3 provide 75 kv BIL level for ISM5_LD_6 when this ISM is used as an LMT or AG6 Retrofit Draw-out type VCB. The kits also include plastic moulded parts to provide emergency (manual) trip and main contacts position indication. For details of these Retrofit Draw-out type VCB designs please contact your nearest Tavrida Electric office or Distributor. 37

40 5..4 Interlocking kits CBkit_Interlock_ This kit is used to link the ISM synchronizing shaft with mechanical interlocks. CBkit_Interlock_ linked with ISM s shaft can provide information about ISM main contacts state (closed, open), emergency (mechanical) trip of ISM and mechanical blocking of ISM closing. CBkit_Interlock_ is optional for ISM5_LD_ and ISM5_LD_. ISM5_LD_3 and ISM5_LD_3 are already equipped with the CBkit_Interlock_ pre-installed. Figure 3 Interlocking kits installed on ISM5_LD_3 CBkit_Interlock_ This kit is used to link the ISM interlocking shaft with mechanical interlocks. CBkit_Interlock_ linked with ISM s shaft can provide manual (emergency) trip / lockout (mechanical blocking of ISM closing) functionality. The kit has an interface for connection with other mechanical interlocks of switchgear and RMU. CBkit_Interlock_ is not applicable for ISM5_Shell_ and ISM5_LD_6. Figure 3 Interlocking kits installed on ISM5_Shell_ CBkit_Interlock_ is applicable for ISM5_Shell only 40

41 CBkit_Interlock_3 This kit is used to link the ISM interlocking shaft with mechanical interlocks. CBkit_Interlock_3 linked with ISM s shaft can provide manual (emergency) trip / lockout (mechanical blocking of ISM closing) functionality by key switch. The kit has an interface for connection with other mechanical interlocks of switchgear and RMU. Figure 33 CBkit_Interlock_3 Interlocking kit installed on ISM5_HD_ CBkit_Interlock_3 is applicable for ISM5_MD and ISM5_HD only CBkit_Interlock_4 This kit is used to link the ISM interlocking shaft with mechanical interlocks. CBkit_Interlock_4 linked with ISM s shaft can provide manual (emergency) trip / lockout (mechanical blocking of ISM closing) functionality by rotary switch. The kit has an interface for connection with other mechanical interlocks of switchgear and RMU. Figure 34 CBkit_Interlock_4 Interlocking kit installed on ISM5_HD_ CBkit_Interlock_4 is applicable for ISM5_MD and ISM5_HD only 4

42 CBkit_Interlock_5 This kit is used to link the ISM interlocking shaft with mechanical interlocks. CBkit_Interlock_5 linked with ISM s shaft can provide manual (emergency) trip by push-button switch. Figure 35 CBkit_Interlock_5 Interlocking kit installed on ISM5_HD_ CBkit_Interlock_5 is applicable for ISM5_MD and ISM5_HD only 5..5 Switching module main contacts position indicator If position indicator is used CBkit_PosInd_ shall be connected to ISM with CBcomp_RelCable_ to provide ISM main contact position indication. ISM5_Shell_ already includes these components. Figure 36 CBkit_PosInd_ with connected CBcomp_RelCable_ 4

43 5. Operation 5.. Closing To close the ISM main contacts, the CM close command shall be applied. It is a dry contact input so no external voltage should be applied. The Close command will be accepted if: CM state is Ready (Ready LED flashes green); no Trip command is applied; optional electrical interlock is unlocked; mechanical and electrical interlock is unlocked (in case of ISM5_MD_, ISM5_Shell_ and ISM5_HD_ only). If Close command is applied and held before the CM is in a Ready state the Close command will not be accepted. If auxiliary power is not available, the manual generator CBunit_ManGen shall be used to charge the CM capacitors and to close the ISM. Mechanical closing is not possible.. Close command input. Trip command input Figure 37 CM_6 close and trip inputs If Manual generators CBunit_ManGen are used to charge the CM, the Manual generator handle shall be rotated until the Ready LED of the CM flashes green (approximately 30 seconds). Then the ISM close command can be applied to the CM. 5.. Opening To open the ISM main circuits, a trip command should be applied to the CM trip command input. It is a dry contact input so no external voltage should be applied. The trip command will be accepted if: CM state is Ready (Ready LED flashes green) or within 60 seconds after the removal of the auxiliary power supply; optional electrical interlock is unlocked; mechanical and electrical interlock is unlocked (in case of ISM5_MD_, ISM5_Shell_ and ISM5_HD_ only). If the trip command is applied and kept before the CM is in a Ready state, the trip command will be accepted after CM is in a Ready state Emergency opening The ISM can also be opened manually. When the synchronizing shaft is rotated, a force exceeding the magnetic attraction forces of the ring magnet is applied to the armature, which subsequently starts to move. As the air gap increases, the opening springs and the contact pressure springs overcome the magnetic holding force, and the vacuum interrupter opens. To open the ISM5_LD and ISM5_LD manually, the force shall be applied to the interlocking pins or torque shall be applied to the stub shaft evenly during their movement - see Figure 9 above and Figure 9 below. Force shall be applied along the pin s movement axis and directed to the ISM frame. The torque shall be applied in the direction of shaft rotation during ISM opening. The force or torque influence shall not be applied at the end of pin s stroke or shaft rotation and shall not be applied to the pin or shaft before ISM closing. 43

44 Figure 38 ISM5_LD and ISM5_LD manual trip execution. Force or torque can be applied to any of the points shown below To open the ISM5_MD, ISM5_Shell and ISM5_HD manually, the torque shall be applied to the interlocking shaft evenly during its movement - see Figure 5 above and Figure 43 below. The torque shall be applied counterclockwise of shaft rotation (90 degrees angle). The torque shall not be applied at the end of shaft rotation. ISM5_MD_, ISM5_Shell_ and ISM5_HD_ has a built in electrical interlock that interrupts the ISM coil circuit after the intelocking shaft is rotated counterclockwise. After manual trip, the shaft should be rotated clockwise to unlock the ISM. Figure 39 ISM5_Shell manual trip execution (ISM5_MD and ISM5_HD have same manual trip execution) 44

47 6. Indication The VCB has the following indication functionality: indication provided by ISM: ISM main contacts position (mechanical indication) - CBkit_PosInd_ with connected CBcomp_RelCable_; ISM main contacts position (electrical indication) - ISM auxiliary switches (6NO+6NC switches for three phase ISMs and NO+NC - for single phase ISMs). indication provided by CM: ISM main contacts position (electrical indication) - one inbuilt CM relay ( NO + NC with common point); CM Power indication - LED indicator; CM Ready state indication - LED indicator and one built in CM relay ( NO + NC with common point); CM Malfunction state indication - LED indicator and one built in CM relay ( NO + NC with common point). Parameters of allowed ISM auxiliary switch load and built in CM relays are given in Chapter 4. The self-diagnostic system inside the CM detects possible malfunctions and reports them via the Malfunction LED blink signals and Malfunction or Loss of auxiliary supply Relay state. The explanation of the blink codes is given in Table 7. Table 7 - CM self-diagnostic indication Indication CM state LED Power LED Ready LED Malfunction Relay Ready Relay Malfunction or Loss of auxiliary supply Power supply voltage is absent more than 3 minutes "Close" operation is preparing off off off O C continuous off off O O CM is ready and operable continuous continuous off C O Power supply voltage is absent for more than.5 seconds off continuous blink C C Excessive trip or close time continuous off blinks O C Actuator coil isolated continuous off 3 blinks O C Short circuit of Actuator coil continuous off 4 blinks O C Manual Trip and Lock continuous off 5 blinks O O Overheat continuous off 6 blinks O O ISM state is open without command from the CM continuous off 7 blinks O C Internal fault of the CM continuous off continuous O C Notes.. Number of blinks in series followed by.5 s intervals, continuous light or off state are shown for LED indicators.. State of relay contact groups (C closed, O opened) is indicated for NC Ready Relay and Malfunction or Loss of auxiliary supply Relay. 3. Period of checking Actuator Coil state (short circuit / isolated) 0 s. Priority of the fault indication starting from the lowest one:. CM overheat ;. ISM state is open without command from the CM; 3. Excessive trip or close time; 4. Manual Trip and Lock; 5. Actuator coil isolated; 6. Short circuit of Actuator coil; 7. Power supply voltage is absent more than.5 seconds. 47

48 CM performs the checkup of ISM main contacts position and updates the ISM main contacts position relay status in the following cases: In case Close command was applied from the CM. In this case the update is performed not later than in 50ms after ISM main contacts closing; In case Trip command was applied from the CM. In this case the update is performed not later than in 70ms after ISM main contacts opening; Periodically every 0s in case no Close or Open command was applied from the CM. In case application project requires to define main contacts position faster than the timing mentioned above it is recommended to use auxiliary switches installed at the ISM. 48

51 7. Configuration options Lower terminal design of ISM The one lower main terminal (conventional terminal) of ISM is usually sufficient for standard applications, but there may be applications where the switchgear is so compact that ISM terminals are used as bus bars, for example Ring main units in city electrical networks. Figure 40 ISM with one lower main terminal Figure 4 ISM with two lower main terminals Figure 4 Example of ISM with two lower main terminals inside of SF-6 isolated Ring main unit 5

52 BIL level of ISM The selection of BIL level of an ISM is related to the VCB and associated insulation parts kits, not necessarily to the ISM itself. Selection of either 75 kv or 95 kv BIL defines whether VCB5_MD_6F will be equipped with CBkit_Ins_4. This kit is optional accessory as its selection depends on the type of bars used for ISM5_MD_ main terminals connection: for bars with cross-section 40x0 mm (single or double bars) the CBkit_Ins_4() shall be used for 95 kv BIL; for bars with cross-section 80x0 mm (single bar) the CBkit_Ins_4() shall be used for 95 kv BIL. The bars with cross-section 80x0 mm are not applicable for ISM5_MD_ with PCD 50 mm due to the bars width that decreases the distance between bars. Figure 43 ISM5_MD_ with CBkit_Ins_4() and double bars 40x0 mm Figure 44 ISM5_MD_ with CBkit_Ins_4() and single bars 80x0 mm The selection of BIL level of an ISM is related to the VCB and associated insulation parts kits, not necessarily to the ISM itself. Selection of either 75 kv or 95 kv BIL defines whether VCB5_Shell_6F will be equipped with CBkit_Shell5_. Only the VCB5_Shell_6F with PCD 50 mm is always equipped with CBkit_Shell5_(05) since distance between poles of ISM5_Shell_(50_L) requires it at 75 kv BIL. Figure 45 ISM5_Shell_ without CBkit_Shell5_: ISM5_Shell_(50_L) - BIL 60 kv due to short distance between poles; ISM5_Shell_ with other PCD - BIL 75 kv. Figure 46 ISM5_Shell_ with CBkit_Shell5_ - BIL 95 kv for all variants of PCD 5

53 Selection of either 75 kv or 95 kv BIL defines whether VCB5_HD_6F will be equipped with bare or isolated bars used for ISM5_HD_ main terminals connection. The shrinkable tube is recommended for the bars isolating. The bars shall have radius at least 3 mm on their edges. Figure 47 ISM5_HD_ with isolated double bars 00x0 mm Selection of either 95 kv or 5 kv BIL defines whether VCB5_LD_6F or VCB5_LD3_6F will be equipped with CBkit_Ins_3. Figure 48 ISM5_LD_, ISM5_LD_3 without CBkit_Ins_3 - BIL 95 kv Figure 49 ISM5_LD_, ISM5_LD_3 with CBkit_Ins_3 - BIL 5 kv CBkit_Ins_3 used in place of bar connections to ISM upper teminals to provide 5 kv BIL. If another design is used, the rated insulation level shall be verified by a dielectric test. CBkit_Ins_3 is not applicable for VCB5_LD_6F as VCB5_LD_6F is intended for usage inside of SF-6 isolated switchgear which already provide 5 kv BIL. Rated voltage of auxiliary circuits Selection of rated supply voltage range defines the rated supply voltage of the CM. Information about ranges of rated voltage of other VCB auxiliary circuits such as ISM auxiliary switches, CM built in relay switching contacts and CM control input circuits is given in Chapter 4. 53

54 7. Primary connections 7.. ISM installation In any switchgear application, the ISM5_Shell and ISM5_HD shall may be installed in position actuator up or actuator down. The ISM5_LD, ISM5_MD and ISM5_LD can be installed in any position. Additionally ISM5_Shell_(50_L) and ISM5_Shell_(0_L) can be installed in horizontal actuator position. In this case the plane of all ISM terminals surfaces shall be horizontal as well and terminals surfaces shall be up oriented.

56 7.. Minimum clearances due to electromagnetic influence Short-circuit current magnetic field influences the ISM magnetic actuator. To avoid unwanted tripping, the minimum clearances between bus bars and the ISM frame should be not less than stated in Table 8.
