Abstract

본 발명은 회로차단기의 접점소모상태를 커버를 개방하지 않고도 표시창을 통해 외부에서 손쉽게 파악 할 수 있도록 하여 접점의 교체가 적절한 시기에 이루어지므로써 화재등의 안전사고를 방지할 수 있도록 한 것이다.The present invention can be easily understood from the outside through the display window without having to open the cover of the contact state of the circuit breaker, so that the replacement of the contact is made at the appropriate time to prevent safety accidents such as fire.

이를 위해, 본 발명은 케이스내부에 대향 설치되는 안내판(2)과, 상기 안내판(2)에 힌지결합되어 고정 및 가동접점의 마모에 따른 가동접점대(1)의 회전시 연동하는 하부링크(5)와, 상기 하부링크(5)에 힌지 결합되어 연동하는 상부링크(9)와, 상기 상부링크(9)에 한지 결합되어 커버(10)의 표시창(11)을 통해 외부에서 접점의 마모상태를 파악할 수 있도록 표식을 갖춘 접점소모상태표시판(12)으로 구성된 회로 차단기의 접점소모상태 표시장치이다.To this end, the present invention is a guide plate (2) opposed to the inside installed in the case, the lower link (5) is hinged to the guide plate (2) interlocking when interlocking when the movable contact table (1) according to the wear of the fixed and movable contacts ), The upper link (9) hingedly coupled to the lower link (5) and the upper link (9) is coupled only to the upper link (9) to the wear state of the contact from the outside through the display window (11) of the cover (10) It is a contact consumption state display device of a circuit breaker composed of a contact consumption state display panel 12 having a mark so as to grasp.
