Title (EN) ELECTRICAL CONTACT SYSTEM
(FR) SYSTÈME DE CONTACT ÉLECTRIQUE
Abstract:
(EN) An electrical contact system includes: a static contact (21, 22), a movable contact (10) and an arc extinguishing device. The arc extinguishing device includes an arc extinguishing member (310, 320) and a driving mechanism for moving the arc extinguishing member. When the movable contact (10) is moved to the switch-on position, the arc extinguishing member (310, 320) is moved beyond the contact area between the movable contact (10) and the static contact (21, 22) so as to allow the movable contact to be in electrical contact the static contact; and when the movable contact is moved to the switch-off position, the arc extinguishing member (310, 320) is moved into the contact area between the movable contact (10) and the static contact (21, 22) such that the movable contact is electrically isolated from the static contact to cut off the electric arc between the movable contact and the static contact. The arc extinguishing member may be driven by the driving mechanism to be quickly moved into the contact area between the movable contact (10) and the static contact (21, 22).
(FR) L'invention concerne un système de contact électrique comprenant : un contact statique (21, 22), un contact mobile (10) et un dispositif d'extinction d'arc. Le dispositif d'extinction d'arc comprend un élément d'extinction d'arc (310, 320) et un mécanisme d'entraînement pour déplacer l'élément d'extinction d'arc. Lorsque le contact mobile (10) est déplacé vers la position de mise en marche, l'élément d'extinction d'arc (310, 320) est déplacé au-delà de la zone de contact entre le contact mobile (10) et le contact statique (21, 22) de façon à permettre au contact mobile d'être en contact électrique avec le contact statique; et lorsque le contact mobile est déplacé vers la position d'arrêt, l'élément d'extinction d'arc (310, 320) est déplacé dans la zone de contact entre le contact mobile (10) et le contact statique (21, 22) de telle sorte que le contact mobile est électroisolé du contact statique pour couper l'arc électrique entre le contact mobile et le contact statique. L'élément d'extinction d'arc peut être entraîné par le mécanisme d'entraînement pour être rapidement déplacé dans la zone de contact entre le contact mobile (10) et le contact statique (21, 22).
