Summary:The present invention provides a contact point monitoring device for a vacuum circuit breaker comprising: a fixed electrode which is fixed in an insulated container; a fixed contact point which is disposed at one end of the fixed electrode; a movable electrode which is installed in the insulated container and is movable in the upward or downward direction; a vacuum interrupter which is disposed at one end of the movable electrode and includes a movable contact point coming into contact with or separated from the fixed contact point; and a pushrod assembly which is coupled to the other end of the movable electrode and allows the movable electrode to move upwards or downwards. The contact point monitoring device comprises: a differentiation sticker which is attached to the outer circumferential surface of a cylindrical rod housing of the pushrod assembly; and a sensor assembly which is adjacent to the pushrod assembly, monitors the position of the differentiation sticker, and has a different sensing direction to the movement displacement of the pushrod assembly. La présente invention concerne un dispositif de surveillance de point de contact pour un disjoncteur à vide comprenant : une électrode fixe qui est fixée dans un contenant isolé ; un point de contact fixe qui est disposé au niveau d'une extrémité de l'électrode fixe ; une électrode mobile qui est installée dans le contenant isolé et qui est mobile dans la direction vers le haut ou vers le bas ; un interrupteur à vide qui est disposé au niveau d'une extrémité de l'électrode mobile et comprend un point de contact mobile entrant en contact avec le point de contact fixe ou séparé du point de contact fixe ; et un ensemble poussoir qui est couplé à l'autre extrémité de l'électrode mobile et permet à l'électrode mobile de se déplacer vers le haut ou vers le bas. Le dispositif de surveillance de point de contact comprend : un autocollant de différenciation qui est fixé à la surface circonférentielle externe d'un boîtier de tige cylindrique de l'ensemble poussoir ; et un ensemble capteur qui est adjacent à l'ensemble poussoir, surveille la position de l'autocollant de différenciation, et présente une direction de détection différente par rapport au déplacement de l'ensemble poussoir. 본 발명은 절연용기 내에 고정되는 고정전극과, 상기 고정전극의 일단에 배치되는 고정접점과, 상기 절연용기 내에 설치되고 상하 방향으로 이동 가능한 가동전극과, 상기 가동전극의 일단에 배치되고 상기 고정접점과 접촉 또는 분리되는 가동접점을 포함하는 진공 인터럽터와, 상기 가동전극의 타단에 결합되고 상기 가동전극을 상승 또는 하강시키는 푸시 로드 어셈블리를 구비한 진공차단기를 위한 접점 감시 장치를 제공한다. 상기 접점 감시 장치는 상기 푸시 로드 어셈블리의 원통형의 로드 하우징의 외주면에 부착되는 감별 스티커, 및 상기 푸시 로드 어셈블리에 인접하고 상기 감별 스티커의 위치를 감시하며 상기 푸시 로드 어셈블리의 이동 변위와 다른 센싱 방향을 갖는 센서 어셈블리를 포함한다.
