for the disconnector and earth switch functions.

By putting the earth switch in the “Earth” position, the circuit breaker shall be positively connected to the

outgoing feeder earth (intertripping circuit; making additional switching operations unnecessary).

All switching device drives shall be located outside of the gas compartments, for easy access. Under

normal operating conditions for indoor switchgear units in accordance with IEC 50594 and when

complying with the specified number of operations, no maintenance is required.

All operations can be performed optionally via a motor-operated mechanism

The mechanical control panel is located at an optimum height for operation and arranged in a recessed

position on the switchgear front. Thus, the operating area is clearly visible while no control elements

protrude from the switchgear front. The position of the individual elements has been selected according to

their function, i.e. according to their allocation to the corresponding device functions. The elements which

form part of a switching device, such as position indicators, crank ports or mechanical pushbuttons, are

visually linked by a specific pattern and integrated in a mimic diagram. Mechanical operation is performed

the same way as with the habitual operation with stationary switching devices. Separate control elements

and mechanical switch position indicators are available for the following functions:

anticipated service life of the switchgear, under normal operating conditions. (The gas-filled clad

compartments are to be designed to be maintenance-free and hermetically sealed pressure systems in

accordance with IEC 62271-200).

The switchgear panels shall be filled with gas and checked for leakage in the factory. For a proper

The action of force on the movable switching contacts is exclusively effected in the required switching

direction. The vacuum interrupter chambers and the metal bellows pertaining to them are protected by

their supporting structure against inadmissible distortion and the action of force. All 3 vacuum interrupters

are actuated together via 1 shaft from the circuit-breaker drive.
