Interlocking for racking the withdrawable disconnector link / disconnector truck
On disconnecting panels racking the withdrawable disconnector link or disconnector truck is interlocked with
mechanical interlock by padlock and optionally also with electromagnetic interlock by solenoid.
Releasing the mechanical interlock is only permissible to lift the operating slide for
opening and closing the actuating opening. The operating slide must otherwise
always be interlocked mechanically by padlock. This is also valid for panel
versions with additional electromagnetic interlock:
Panel versions with electromagnetic interlock are identified on the high-voltage
door with a label for interlocking the disconnecting function:
The procedure for racking the withdrawable disconnector link / disconnector truck to service position and/or
test position is identical with the procedure for racking the withdrawable circuit-breaker / circuit-breaker truck
to service position and/or test position.
For racking the withdrawable disconnector link / disconnector truck to service position and/or
test position, see chapter 10.8 and/or 10.9.
