Application

The interlocking for 1 1/2 breaker diameter (BH_CONN, BH_LINE_A, BH_LINE_B) functions are
used for lines connected to a 1 1/2 breaker diameter according to figure 149.
BH_LINE_A
IEC04000513 V1 EN-US
Figure 149: Switchyard layout 1 1/2 breaker
Three types of interlocking modules per diameter are defined. BH_LINE_A and BH_LINE_B are
the connections from a line to a busbar. BH_CONN is the connection between the two lines of
the diameter in the 1 1/2 breaker switchyard layout.
For a 1 1/2 breaker arrangement, the modules BH_LINE_A, BH_CONN and BH_LINE_B must be
used.
13.4.9.2

Configuration setting

For application without QB9 and QC9, just set the appropriate inputs to open state and
disregard the outputs. In the functional block diagram, 0 and 1 are designated 0=FALSE and
1=TRUE:
• QB9_OP = 1
• QB9_CL = 0
• QC9_OP = 1
• QC9_CL = 0
If, in this case, line voltage supervision is added, then rather than setting QB9 to open state,
specify the state of the voltage supervision:
• QB9_OP = VOLT_OFF
• QB9_CL = VOLT_ON
