Abstract

기중 차단기가 개시된다. 본 발명의 실시 예에 따른 기중 차단기는 CT 자석부를 포함한다. CT 자석부는 외부에 노출된 가동 접점대를 덮도록 기중 차단기에 구비된다. CT 자석부의 외형을 형성하는 케이스의 내부에는, CT 자석이 구비된다. CT 자석은 독자적으로 부 자기장을 형성하거나, 아크 소호부에 구비되는 소호 자석과 함께 주 자기장을 형성한다. CT 자석이 형성하는 자기장에 의해, 발생된 아크는 아크 소호부를 향하는 방향의 전자기력을 인가받는다. 이에 따라, 발생된 아크가 신속하게 이동 및 소호될 수 있다.
