摘要： A high tension or medium tension circuit breaker having abutting arcing contacts. The circuit breaker includes a gastight insulating case filled with a gas having good dielectric properties. The case contains a stationary arcing contact; a moving arcing contact driven by a drive rod actuated by a mechanism outside the case. A blast chamber is defined by a piston integral with the moving arcing contact, slidably received in a fixed cylinder terminating in a blast nozzle, the cylinder and a ring. The circuit breaker further includes a lost motion mechanism to enable the drive rod to move over a given length in the circuit breaker opening direction without driving the moving arcing contact away from the fixed arcing contact.

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.

摘要： An electric switch includes a first arcing contact surrounded by a puffer break chamber in which the gas is pressurized by the thermal effect, and a second arcing contact movable along an axial direction relative to the first arcing contact. The break chamber includes an inner partition separating a first compartment of fixed volume from a second compartment of smaller volume, both compartments being filled with the gas under pressure and each possessing an orifice to blast the arc, the orifices being separate and placed in series along the axial direction. Each compartment is connected to its own orifice via a respective blast channel. The compartments communicate with each other via a channel that is closed by an excess pressure vent device allowing gas at excess pressure to pass in one direction only from the smaller volume compartment to the larger volume compartment.
