Mode of operation The operating shaft forms one unit together with the three contact blades. Due to the arrangement of the fixed contacts (earth busbar), it is not necessary to interlock the CLOSE and EARTHING functions. Three-position switch-disconnector Busbar CLOSED OPEN R-HA41-132a.tif Closing operation EARTHED During the closing operation, the operating shaft with the moving contact blades changes from the OPEN to the CLOSED position. The force of the spring-operated mechanism ensures a high closing speed and a reliable connection of the main circuit. HA eps Feeder Moving contact Opening operation During the opening operation, the arc is caused to rotate by the arc-suppression system. This rotation movement prevents the development of a fixed root. The isolating distance in gas established after breaking fulfills the conditions applicable to isolating distances in accordance with IEC / EN / VDE ) and IEC / EN / VDE ). Due to the arc rotation caused by the arc-suppression system, both load currents and minor no-load currents are safely interrupted.

34 Components Operating mechanisms for the three-position switch Features Mechanical endurance of more than 1000 operating cycles Parts subjected to mechanical stress are made of nonrusting materials Manual operation with the help of a slip-on operating lever : Motor operation Control board with accordingly cut-out switching gate prevents the three-position switch-disconnector from being switched directly from the CLOSED via the OPEN to the EARTHED position Two separate actuating openings are provided for unambiguous selection of the DISCONNECTING and EARTHING functions Operation via rotary movement, operating direction according to IEC /EN 60447/ VDE 0196 (recommendation of VDE /FNN.) Spring-operated mechanism The switching movements are performed independently of the operating speed. Spring-operated / stored-energy mechanism The switching movements are performed independently of the operating speed. During the charging process, the closing and opening springs are charged. This ensures that the switch-disconnector / fuse combination can switch off all types of faults reliably even during closing. Closing and opening is done via pushbuttons, and is therefore identical with the operation of circuit-breaker operating mechanisms. An energy store is available for tripping by means of an operating HV HRC fuse or via a shunt release (f-release). After tripping, a red bar appears on the position indicator.

Mode of operation HV HRC fuse tripped Following the tripping of an HV HRC fuse-link, the mechanism for charging the spring must be set to the OPEN position. Subsequently, earthing can be implemented by means of the three-position switch-disconnector and e.g. the fuse can be replaced. Replacement of HV HRC fuse-links (without any tools) Isolating and earthing of the transformer feeder Opening the connection compartment cover Subsequent manual replacement of the HV HRC fuse-link. Note to HV HRC fuse-links According to IEC (2009) Clause 6.6, the breaking capacity of HV HRC fuses is tested within the scope of the type test at 87% of their rated voltage. In three-phase systems with resonance-earthed or isolated neutral, under double earth fault and other conditions, the full phase-to-phase voltage may be available at the HV HRC fuse during breaking. Depending on the size of the operating voltage of such a system, this applied voltage may then exceed 87% of the rated voltage. It must therefore already be ensured during configuration of the switching devices and selection of the HV HRC fuse that only such fuse-links are used, which either satisfy the above operating conditions, or whose breaking capacity was tested at least with the maximum system voltage.

Mode of operation For the ready-for-service indicator, a gas-tight measurement box is installed inside the switching-device vessel. A coupling magnet, which is fitted to the bottom end of the measurement box, transmits its position to an outside armature through the non-magnetizable stainless-steel switching-device vessel. This armature moves the readyfor-service indicator of the switchgear. While changes in the gas density during the loss of gas, which are decisive for the dielectric strength, are displayed, temperature-dependent changes in the gas pressure are not. The gas in the measurement box has the same temperature as that in the switching-device vessel. The temperature effect is compensated via the same pressure change in both gas volumes.

54 Components Indicating and measuring equipment Short-circuit / short-circuit-to-earth and earth-fault indicators make Kries Ring-main, cable, transformer and circuit-breaker feeders can optionally be equipped with short-circuit, short-circuitto-earth or earth-fault indicators in different designs. The equipment features are shown in the table on page 53. The three most common types of faults in medium-voltage systems are earth faults in cables and switchgear, faults and overloads of distribution transformers, as well as short circuits in cables and switchgear. For fast fault location and minimization of downtimes, electronic fault indicators with the following properties are used: Selective fault detection, and thus minimization of downtimes Reliable fault detection through electronic measuredvalue acquisition Remote indication of fault events and measured values. 1. Short-circuit indicators (IKI-20, IKI-50) are used for selective location of multi-phase faults in distribution systems. The more consequently these are installed in ring-main units, the more selectively the cable fault will be delimited, and shut down quickly. If the fault indication shall result in a remote switching operation, it is advisable to provide a fault detection system on every switchable feeder, so that only the switchdisconnectors located next to the fault must be operated. 2. Earth-fault indicators a Short-circuit-to-earth indicators are used for single-phase short-circuit-to-earth detection in impedance-earthed or briefly impedance-earthed systems. The short-circuit-to-earth detection is already integrated in most of the short-circuit indicators, or available as a separate device. (IKI-10light-P) b In resonance-earthed or isolated systems, earth-fault indicators are used to detect single-phase phase faults. The following procedures can be selected: Pulse location, wattmetric and passing contact procedures. 3. Combined short-circuit and earth-fault indicators (IKI-20PULS, IKI-50) allow for detection of single-phase and multi-phase faults. Here, short-circuit detection can be combined with various earth-fault detection methods (see 2b). R-HA eps R-HA eps R-HA eps IKI-20 IKI-50 IKI-10light-P 4. Devices with direction detection (IKI-50) offer unambiguous fault indication and direction information even in closely operated rings and in power systems with decentralized power supply. To determine the direction, the phase voltages are required. These can be acquired by an existing integrated voltage detecting system type CAPDIS, and made available to the directional fault indicator. 5. Combined fault and load flow indicators (IKI-50) allow in parallel to the fault detection to determine the measured values for all relevant medium-voltage measurands, including the direction.
