제 3 도는 이 발명의 요부상세를 표시하는 단면도.
* 도면의 주요부분에 대한 부호의 설명
7 : 피스톤 8 : 아크 접촉자
13 : 고정 접촉자 14 : 슬라이딩 접촉자
15 : 실린더 16 : 가동 접촉자

Claims (3)

  1. 고정 접촉자와, 이 고정 접촉자와 공통축심이며 원통상으로 배치되고 상기 고정 접촉자에 접리하는 가동 접촉자와, 상기 고정 및 가동 접촉자의 외주를 포위하고 소호매체를 봉입한 탱크를 형성하는 절연통과, 상기 가동 접촉자를 보지하는 피스톤과, 상기 절연통보다도 고강도이고 상기 절연통 내면에 밀착하여 상기 피스톤 외주부와 내접하는 슬라이딩면이 상기 가동 접촉자의 동작방향에 따라서 소정길이로 형성되고 상기 피스톤과 함께 축압공간을 형성하는 실린더와, 상기 실린더 내면에 대향하는 상기 피스톤의 외주부에 상기 실린더 내면을 슬라이딩하는 슬라이딩 접촉자를 구비하고, 상기피스톤의 축방향의 양단부 근방에 전주에 걸쳐서 상기 실린더 내면에 슬라이딩 접촉하는 피스톤 링을 장착한 것을 특징으로하는 개폐기의 소호장치.
  2. 제 1 항에 있어서, 실린더의 선팽창율은 상기 절연통의 선팽창율보다 큰 재료로 구성된 것을 특징으로하는 개폐기의 소호장치.
  3. 제 1 항에 있어서, 실린더는 도전성이 있으며 개폐기의 전로를 구성하는 것을 특징으로하는 개폐기의 소호장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
