Abstract

본 발명은 전기 선로상에 설치되어 사고전류의 발생시 이를 차단시켜 부하기기를 보호하는 회로차단기에 관한 것으로, 전류차단작동시 아크에 의해 발생하는 접점 용융물로 부터 부품들을 안전하게 보호하여 용융물의 용착으로 인한 고장과 수명단축을 방지하고 부품수를 줄여 조립작업이 용이해지도록 한 것이다.The present invention relates to a circuit breaker installed on an electric line to protect a load by blocking it when an accidental current occurs, and protects parts from contact melt generated by an arc during current interruption operation, resulting in welding of the melt. It prevents failure and shortened life and reduces the number of parts to facilitate assembly work.

차단기내에 고정된 샤프트(1)와, 상기 샤프트에 한류중심편(9)으로 결합되어 한류작동시 한류중심핀을 중심으로 회전운동을 하는 가동접촉자(4)와, 상기 샤프트에 래치핀(10)으로 결합되고 일측 슬라이딩면이 상기가동 접촉자에 끼워진 스토퍼핀(11)과 접촉되어 가동접촉자의 회전운동에 따라 연동하는 한류래치(7)와, 상기 샤프트와 한류래치 사이에 설치되어 가동 접촉자에 접촉하중을 작용시키고 한류래치에 항상 일방향의 회전력을 작용시키는 압축코일 스프링(12)으로 구성된 회로차단기의 한류장치이다.A shaft (1) fixed in the circuit breaker, a movable contactor (4) coupled to the shaft by the current-centered piece (9) to rotate around the current-centered pin during the current-driving operation, and a latch pin (10) on the shaft. And a one-side sliding surface is contacted with the stopper pin 11 fitted to the movable contact and interlocked according to the rotational movement of the movable contactor, and is installed between the shaft and the current latch to contact the movable contactor. It is a current-limiting device of a circuit breaker consisting of a compression coil spring 12 for applying a force and always a rotational force in one direction to the current-limiting latch.
