Description

저전압 접촉 구조를 갖는 회로차단기
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1 도는 닫힌(실선)위치와 열림(접선)위치에서 주요접촉을 보여주는 입면도.
제 2 도는 기울어진 후 열린 위치에 대한 접촉 아암의 초기운동중에 주요접촉과 아아크접촉의 닫힌 위치를 보여주는 입면도.

Claims (6)

  1. 첫번재와 두번째 주요접촉과 첫번째와 두번째 아아크 접촉, 열리고 닫힌 위치사이에 이동가능한 첫번째와 두번째 접촉, 접촉을 복구 가능하게 열리게 하기위한 작동기구, 첫번째 접촉을 운반하고 첫번째 추측에서 추측방향으로 솟아오른 첫번째 접촉 아암, 두번째 아아크 접촉을 운반하고 두번째 추측에서 추측방향으로 솟아오른 두번째 접촉 아암, 두번째 주요접촉을 운반하고 두번째 추측에서 추측방향으로 솟아오른 세번째 접촉 아암, 닫힌 접촉위치에서 복구 가능한 기구를 잠그고 기구를 방면하기 위한 트립구조, 미리결정된 과전류 등급아래에서 닫힌 주요접촉을 금기쉽게 유지하기 위한 바이어스수단, 그리고 연속적으로 아아크 접촉을 닫고, 주요접촉을 열고, 그때 아아크 접촉을 얻기위한 두번째 접촉 아암의 열린 운동동안 작동하는 바이어스수단을 포함하는 차단기구조로 이루어진 회로차단기.
  2. 제 1 항에 있어서, 세번째 접촉 아암이 두번째 접촉 아암과 이웃하는 회로차단기.
  3. 제 2 항에 있어서, 세번째 접촉 아암이 한쌍의 주요접촉 아암을 포함하는 회로차단기.
  4. 제 3 항에 있어서, 두번째 주요접촉이 한쌍의 주요접촉, 각 세번째 접촉 아암상에 하나의 접촉을 포함하는 회로차단기.
  5. 제 4 항에 있어서, 바이어스수단이 주요접촉이 열린 다음까지 첫번재와 두번째 주요접촉을 함께 유지하고 아아크접촉을 함께 유지하기 위한 스프링을 포함하는 회로차단기.
  6. 상기에 기술되고 부수하는 도면을 참고로 예시된 바와같이 실질적으로 사용을 위하여 구성되고 응용된 회로차단기.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
