Abstract

기중 차단기가 개시된다. 본 발명의 실시 예에 따른 기중 차단기는 커버 자석부를 포함한다. 커버 자석부는 기중 차단기의 외형을 형성하는 상부 커버에 직접 결합된다. 커버 자석부는 고정 접점에 인접하게 위치하여 자기장을 형성한다. 형성된 자기장에 의해, 발생된 아크는 아크 소호부를 향하는 방향의 전자기력을 인가받는다. 이에 따라, 발생된 아크가 신속하게 이동 및 소호될 수 있다. 커버 자석부는 상부 커버의 면에 삽입되어, 외부로 노출되지 않는다. 따라서, 발생된 아크는 커버 자석부에 접촉되지 않는다. 결과적으로, 발생된 아크에 의해 커버 자석부가 손상되지 않게 된다.
