The present invention relates to a breaker protection coordination method for a submarine using a shunt trip coil in which when a problem occurs at an output terminal of a propulsion motor in a power supply situation through a part of a plurality of batteries connected in parallel with the propulsion motor, a circuit breaker forced open signal is forcibly applied to a large current circuit breaker which is directly connected through a short-circuit current limiting device and a hard wire circuit, and, after that, if a grid voltage shows a recovery trend, a semiconductor switch of the short-circuit current limiting device is prevented from being blocked.

    본 발명은 추진전동기와 병렬 연결된 다수의 배터리 중 일부 배터리를 통한 전력공급 상황에서 추진전동기 출력단의 문제 발생 시, 단락전류제한장치와 하드와이어 회로를 통해 직접 연결된 대전류 차단기에 차단기 강제개방신호를 강제로 인가하고, 이후 계통전압이 회복추세를 보일 경우 단락전류제한장치의 반도체스위치가 차단되지 않도록 조치하는 션트 트립 코일을 이용한 잠수함용 차단기 보호협조방법에 관한 것이다.
