4.2.1.3 Parameter setting
Interlocking
For a line bay in section 2, the same conditions as above are valid by
changing section 1 to section 2 and vice versa.
If there is no bypass busbar and therefore no Q7 disconnector, then the
interlocking for Q7 is not used. The states for Q7, Q75, C_DC, BC_AC,
BC_BC are set to open by setting the appropriate module inputs as fol-
lows. In the functional block diagram, 0 and 1 are designated 0=FIXD-
OFF and 1=FIXD-ON:
• Q7_OP = 1
• Q7_CL = 0
• Q75_OP = 1
• Q75_CL = 0
• C_DC_OP = 1
• C_DC_CL = 0
• BC_AC_OP = 1
• BC_AC_CL = 0
• BC_BC_OP = 1
• BC_BC_CL = 0
• EXDU_BPB = 1
• VP_C_DC = 1
• VP_BC_AC = 1
• VP_BC_BC = 1
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, BC_BC
are set to open by setting the appropriate 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
• BC_BC_OP = 1
• BC_BC_CL = 0
• VP_BC_AB = 1
