Interlocking
This section describes how the interlocking for a certain switchgear con-
figuration can be realized by using standard interlocking modules and
their interconnections. It also describes the parameter settings. The
EXVVA_xx input signals, which are normally not used, are always set to
1=FIXD-ON. The inputs for delivery specific conditions (QxEXy) are set
to 1=FIXD-ON, if they are not used except:
• Q9EX2 and Q9EX4 in modules BH_LINE_A and BH_LINE_B
• Q0EX3 in module AB_TRAFO
which are set to 0=FIXD-OFF.
The signals from other bays connected to the module ABC_LINE are
described below.
To derive the signals:
C_DC_OP
All line disconnectors on bypass C except in the own bay are open.
VP_C_DC
The switch status of C_DC is valid.
EXDU_BPB
Signal if no transmission error from any bay connected to a bypass bus-
bar.
These signals from each line bay (ABC_LINE) except that of the own bay
are needed:
Q7OPTR
Q7 is open
VPQ7TR
The switch status Q7 is valid.
EXDU_BPB
Signal if there is no transmission error from the bay that contains the
above information. This signal is taken from the data valid output on the
command function block.
