摘要： A control device for controlling electrical switchgear such as a circuit breaker or the like includes an actuating arm having a connection point suitable for being moved along a closed line including points P1, P2 and P3. The connection point thus moves during an opening stage for opening the moving contact, under the effect of a mechanical spring from point P1 to point P2. It also moves during a re-cocking stage for re-cocking the mechanical spring under the effect of a motor being switched on, and while keeping the moving contact in the open position, from point P2 to point P3. It also moves during a closure stage for closing the moving contact, also under the effect of the motor being switched on, from point P3 to P1. In this manner it is possible to successively perform three distinct stages of putting the actuating arm in motion, between the instant at which the moving contact leaves its closed position and the instant at which it returns thereto after having occupied its open position. A re-cocking stage for re-cocking the mechanical spring that is distinct from the closing stage and from the opening stage for closing and opening the moving contact, is performed, with the opening stage to be performed merely by releasing the energy that has been previously accumulated by the spring.

摘要： The gas exhaust comprises a generally cylindrical shaped casing (26) closed by a bottom (18, 22) at one end and with openings (30) to allow gas to escape. A duct (16) is arranged in the casing (26) to delimit a central passage inside the duct, and an annular passage (42) surrounding the central passage (40) outside the duct between it and the casing (26). There is a communication consisting of four holes (20) in the duct (16) close to the bottom (18) to form a communication between the central passage (40) inside the duct (16) and the annular passage (42). The casing (26) includes two diametrically opposite openings (30) located in a horizontal plane.

摘要： A circuit-breaker includes two contacts which are disposed in an interrupting space filled with a dielectric gas under pressure and between which an electric arc strikes during circuit-breaker opening, a thermal blast chamber communicating directly with the interrupting space, and a piston-driven compression chamber communicating with the thermal blast chamber. The piston-driven compression chamber communicates with the interrupting space via a discharge channel that is separate from the thermal blast chamber and that is closed by a discharge valve. The discharge valve is disposed between the thermal blast chamber and the piston-driven compression chamber in a manner such that the discharge valve opens to enable the gas under increased pressure in the piston-driven compression chamber to be discharged towards the interrupting space via the channel when the increase in the pressure of the gases in the thermal blast chamber is larger than the increase in the pressure of the gases in the piston-driven compression chamber.
