Interlocking
The project-specific logic for input signals concerning bus coupler are the same as the
specific logic for the line bay (ABC_LINE):
6LJQDO
BC_AB_CL
Signal if a bus-coupler connection exists between busbar A and B.
VP_BC_AB
The switch status of BC_AB is valid.
EXDUP_BC
Signal if there is no transmission error from bay BC (bus-coupler bay).
The logic is identical to the double busbar configuration described in "Signals from bus
coupler".

If there is no second busbar B and therefore no Q2 disconnector, then the interlocking
for Q2 is not used. The state for Q2, Q25, BC_AB are set to open by setting the appro-
priate module inputs as follows. In the functional block diagram, 0 and 1 are designated
0=FIXD-OFF and 1=FIXD-ON:
•
Q2_OP = 1
•
Q2_CL = 0
•
Q25_OP = 1
•
Q25_CL = 0
•
BC_AB_CL = 0
If there is no second busbar B at the other side of the transformer and therefore no TQ2
disconnector, then the state for TQ2 is set to open by setting the appropriate module in-
puts as follows:
•
TQ2_OP = 1
•
TQ2_CL = 0

The interlocking module A1A2_BS is used for one bus-section circuit breaker between
section A1 and A2 according to figure 133. The module can be used for different bus-
bars, which includes a bus-section circuit breaker, that is, not only busbar A.
