Abstract: A switching assembly comprises a pair of fixed contacts, and a contact bridge movable between a bridging position in which the contact bridge electrically connects the contacts and a separated position in which the contacts are electrically separated. A detector of the assembly includes at least one sensor for detecting the presence of the contact bridge in at least one of the separated position or the bridging position, and a controller operatively connected to the sensor and having a first switching point and a second switching point. One of the switching points is associated with a position of the contact bridge between the bridging position and the separated position.

Abstract: A switch assembly comprises a plurality of contacts, a switch including a contact bridge and an armature connected to the contact bridge, and a switch status detector positioned remotely and electrically isolated from the switch. The switch has an open position in which the contacts are electrically separated from one another and a closed position in which the contacts are in electrical contact with each other through the contact bridge. The switch status detector includes an electronic oscillator coupled with a coil wrapped around a core. The switch status detector outputs an oscillating voltage that varies depending upon a position of the switch between the open position and the closed position.

Abstract: This invention relates to a circuit breaker (1) for high or medium voltages, of the type having a drive bar (70) coupled to a drive member, and a circuit-breaking chamber (2) facing it and having two contacts (3, 4), each contact (3, 4) including a main contact (30, 40 respectively) and an arcing contact (31, 41 respectively), with one of the two contacts (3) being fixed to a blast or extinguishing nozzle (32). According to the invention, the second contact (4) and the drive bar (70) are joined together by coupling means (6) in such a way that they move together in translation in the same direction, the transmission means (5) being disposed on the side (21) of the chamber (2) that is adjacent to the drive bar (70), and are adapted to transmit the motion of the driven second contact (4) to the first contact (3).

Abstract: This hybrid circuit breaker has at least two series-connected arcing chambers which are operated by a common drive or by separate drives and are filled with different arc extinguishing media. The arc extinguishing and insulating medium in the first arcing chamber surrounds the second arcing chamber in an insulating manner. The aim is to provide a hybrid circuit breaker which can be produced economically and which has high availability. This is achieved, inter alia, wherein means are provided which always ensure that the movement of the first arcing chamber leads the movement of the second arcing chamber during a disconnection process, and that the movement of the second arcing chamber always leads the movement of the first arcing chamber during a connection process.

Abstract: This power circuit-breaker has at least one cylindrically constructed arcing chamber which is provided with a stationary contact, with a moving contact and with a quenching zone between the two contacts. A shaft of the moving contact is permanently connected to a blowout volume which is closed off on the stationary contact side by an insulating nozzle through which at least one flow channel passes. The arcing chamber has a first compression volume which is operatively connected to the blowout volume and to a second compression volume. It is intended to provide a power circuit-breaker in which the blowing-out of the arc with pure SF.sub.6 gas is made stronger. This is achieved by providing a moving auxiliary piston between the first compression volume and the second compression volume and by the auxiliary piston being connected to the moving contact via a direction-changing device.
