Description

진공차단기용 접점
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명이 적용되는 진공차단기의 구조를 보인 단면도.
제2도는 제1도의 전극부분의 확대단면도.
제3도는 본 발명의 접점재료에 있어서의 합금에 대한 Cu의 체적비율울 25%로 고정하고 나머지 75%부분을 Mo와 W로 중량 배분한 경우의 내전압(耐電壓) 성능의 변화를 나타낸 특성도.
도면에 있어서 (1)은 진공절연용기, (2)와 (3)은 단판(端板), (4),(5)는 전극, (6)과 (7)은 전극봉(棒), (8)은 벨로우즈(bellows), (9),(10)은 시일드(seald), (51)은 납땜재료이다.

Claims (4)
