Abstract
Description
Claims (3)
- 고정접점과 가동접점으로 된 다극의 개폐접점과, 상기 가동접점을 갖는 가동접촉자를 개폐가능하게 개폐방향으로 굴곡하고 대략 U자형으로 정형한 가요도체와, 상기 가요도체의 통전전류에 의한 상기 U자형의 개확방향의 전자력을 상기 가동접점의 압압력으로 변환하는 지렛대작용의 지축과 상기 전자력을 강화하는 상기 가요도체의 U자형의 측면극간에 배치한 자성판과, 이 자성판을 병렬배치 다수로 해서 그 사이에 자기공극을 개재시킨 것을 특징으로 하는 기중차단기.
- 제1항에 있어서, 상기 자성판을 다극의 개폐접점의 극간에 까지 연재시킨 것을 특징으로 하는 기중차단기.
- 제1항 또는 제2항에 있어서, 기중차단기의 외각을 형성하는 절연수지제의 함체에 설치된 다극의 개폐접점을 절연 격리하는 상간격벽과 이 상간벽에 자기공극 상당의 공극을 가지고 뚫린 삽입홈에 자성판을 삽입 배치한 것을 특징으로 하는 기중차단기.
