Abstract

PURPOSE: To prevent wrong interlocking, by operating auxiliary relays through the a-contacts and b-contacts of circuit breakers.
CONSTITUTION: The interlocking conditions of the front of a circuit breaker 52S1 are established by auxiliary relays L1X, L1Y. The circuit of the auxiliary relay L1X consists of auxiliary relays 52BaX, 52S2aX contact-amplified by the a-contacts of the circuit breakers. When a circuit breaker 52B or 52S2 is opened, the auxiliary relay L1X is set. When both the circuit breakers 52B and 52S2 are closed, the auxiliary relay L1X is reset. The circuit of the auxiliary relay L1Y consists of auxiliary relays 52BbX, 52S2bX contact-amplified by the b-contacts of the circuit breakers. The auxiliary relay L1Y is set when the circuit breaker 52B or 52S2 is open and is reset when both the circuit breakers 52B, 52S2 are closed.
