Figure 235: Arc protection
Two master trip logics TRPPTRC1_86/94-1 and TRPPTRC2_86/94-2 are provided as a
trip command collector. TRPPTRC1_86/94-1 is dedicated for the breaker 1 and
TRPPTRC2_86/94-2 for breaker 2.
Circuit breaker failure protection CCBRBRF1_50BF-1 is initiated via the PICKUP input
by a number of different protection functions available in the relay and 50BF-1 protection
functions and is connected to trip output contact PO3 (X100:16-19), and
TRPPTRC2_86/94-2 collects the almost the same trip signals except the one for
CCBRBRF1_50BF-1, instead, CCBRBRF1_50BF-1 being replaced with
CCBRBRF2_50BF-2 and is connected to trip output (X100:21-24).
Open control commands from circuit breaker control CBXCBR1_52 function block to the
circuit breaker from the local or remote are also connected directly to the outputs PO3
(X100:16-19) and PO4 (X100:21-24) respectively.
With a high-speed binary output card, ARCSARC1...3_AFD-1...3 are connected to
high-speed output HSO1 (X110:15-16), HSO1 (X110:19-20) and HSO1 (X110:23-24)
respectively. Without the high-speed output card, it is the user's choice to connect the arc
protection outputs to whatever outputs available.
TRPPTRC1_86/94-1 and TRPPTRC2_86/94-2 provides the lockout/latching function,
event generation and the trip signal duration setting. If the lockout operation mode is
selected, one binary input can be reassigned to the RST_LKOUT input of the Master Trip
to enable external reset with a push button.
