摘要： A puffer type liquefied-gas self-injection circuit breaker, used for the interruption at low temperature of a high current carried by a high-voltage power line. The circuit breaker comprises a first fixed contact and a compression chamber. The compression chamber has a bottom part which is fixed and an upper part of which is movable in the axial direction with respect to the bottom part. The upper part of the compression chamber comprises a second contact and an envelope concentrically disposed thereabout. An insulating nozzle is formed in a top portion of the envelope. The internal wall of the envelope is so shaped as to exactly match the external profile of the bottom part of the compression chamber. The breaker is also equipped with a liquefied-gas self-injection system which injects the liquefied-gas from their storage tank via a feed line and valve directly onto the electric arc formed at the moment of current interruption. This system comprises an injection chamber located in the wall of the moving part of the compression chamber. The injection chamber is terminated at one end by a narrow injection channel acting as a nozzle directed towards the electric arc while the other end rests on a compression piston formed by a pre-injection chamber. The latter forms an integral part of the fixed bottom part of the compression chamber and is equipped at its top end with a check valve permitting its use as a compression piston when the valve is closed and permitting the transfer of liqufied-gas to the injection chamber when the valve is in the open position. A storage tank placed at the bottom of the compression chamber provides for the recuperation by gravity of all the liquefied-gas in the apparatus.

摘要： A high-voltage circuit-breaker has an interrupting chamber comprising a gas-tight cylindrical casing filled with a gas having good insulative properties such as sulfur hexafluoride. The casing contains a fixed permanent contact, a fixed arc contact and a mobile assembly comprising permanent contacts and arc contacts and associated with a gas blast assembly. The chamber also contains a carbon-based resistor having a resistance of approximately 500 ohms connected in parallel with the circuit-breaker contacts when the arc contacts are opened by an auxiliary switch. This resistor is connected in series with an arrangement of varistors, the resulting combination being disposed inside the casing and connected in series with the auxiliary switch. Opening of the auxiliary switch is effected by opening of the circuit-breaker. The volume of the resistor is greater than that of the arrangement of varistors by a factor of at least five.

摘要： A high tension circuit-breaker has an insulating case filled with a dielectric gas such as SF.sub.6. A high capacitance capacitor and at least a varistor are electrically interconnected in parallel and are connected to a first terminal. The capacitor and varistor are associated with an insertion mechanism which momentarily inserts the capacitor and varistor in parallel with the arcing contacts during circuit-breaker disengagement or engagement. The insulating case is extended by at least one conductive case housing both the capacitor and at least part of the varistor.
