Abstract:
In order to reduce the breaking energy of a high-voltage or medium-voltage circuit-breaker, the interrupting chamber (10) contains two contacts (12, 14) mounted to move in opposite directions, and actuated via a single device (20). The two contacts (12, 14) are surrounded by an insulating casing (18) of tubular shape, coupled in fixed manner to the main contact (12). The contacts (12, 14) are actuated by a device having a lever (24) in which each lever arm is coupled to a link, one of the links (32) being secured to the insulating casing (18) and the other link (34) being secured to the second contact (14). The guiding of the drive tube (18) on the main contacts (12b, 14b) makes it possible to improve breaking by keeping clean gas between said main contacts.
