Interlocks in case of busbar earthing switch and bus sectionalizer

Switch positiong     

Interlock

The earthing switch can only be switched on if all disconnectors assigned to 
the busbar are “OFF”.

Earthing switch "ON". The interlock acts on all disconnectors assigned to 
the busbar.

Bus sectionalizer locked in “ON” or “OFF” position, except when all disconnectors 
in a busbar section are in “OFF” position.

Interlocks in case of bus coupler in two panel widths

on front control panel (interrogating lever locked electro-magnetically)
The interlocks act as appropriate in case of remote control

- Bus section coupler: analogously in case of single and double busbar switchgear
- Bus coupler: analogously in one panel width
- Interlocks: apply analogously even if BB1 and BB2 are interchanged
