Abstract
A controller for electrical equipment, in particular for a high-voltage circuit-breaker, the equipment being housed in a casing filled with a dielectric gas under pressure. An interrupting chamber within the casing extinguishes arcs produced by the main circuit-breaker contacts. The equipment employs a contact connecting rod designed to be moved in translation by said controller. The controller employs an operating piston mounted to slide in a cylindrical element fixed to the casing and connected to a communication duct for communicating with the inside of the casing via an actuating valve in the engagement position. The controller further includes a suction enclosure connected to said cylindrical element and communicating with the inside thereof via a communication duct when the actuating valve is in the disengagement position. A suction piston is mounted to slide in the enclosure. In addition, a reciprocating drive mechanism drives the suction piston in a reciprocating motion.
