4.2.7.2 Signals in double-
breaker arrangement
Interlocking
For a bus-section disconnector, these conditions from the B2 busbar sec-
tion are valid:
Q2(20)OPTR (bay 1/sect B2)
. . .
. . .
. . .
Q2(20)OPTR (bay n/sect B2)
DCOPTR (B2/B3)
VPQ2(20)TR (bay 1/sect B2)
. . .
. . .
. . .
VPQ2(20)TR (bay n/sect B2)
VPDCTR (B2/B3)
EXDUP_BB (bay 1/sect B2)
. . .
. . .
. . .
EXDUP_BB (bay n/sect B2)
EXDUP_DC (B2/B3)
Fig. 27 Signals from any bays in section B2 to a bus-section discon-
nector
If the busbar is divided by bus-section disconnectors, the signal for the
busbar disconnector bay no other disconnector connected to the bus sec-
tion must be made by a project-specific logic.
The same type of module (A1A2_DC) is used for different busbars, that
is, for both bus-section disconnector A1A2_DC and B1B2_DC. But for
B1B2_DC, corresponding signals from busbar B are used.
