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： An electric circuit-breaker in which the arc extinction chamber is filled with liquefield SF6 under pressure.The moving contact of the circuit-breaker cooperates with a blast-piston which, during opening of the breaker and after the moving contact has reached its ultimate open position, continues its travel in order to produce an intensive and protracted circulation of liquid dielectric from the arc extinction chamber in the region where the arc strikes across the contacts.Applications to ultra-high-speed breaking of high-tension, high-intensity alternating currents.

摘要： A mechanical switch in the form of a bypass switch assembly is arranged between two electrical conductors (busbars) and stays open during normal operation. When a cell fault happens, the fault and bypass information is transmitted to an actuator (acting as a trigger circuit) which activates inter alia a gas generator producing huge volume of gas in a very short time. The gas pressure pushes a movable member to bridge the two electrical conductors with ultrafast speed.

摘要： A high voltage, high power circuit interrupter uses liquid SF.sub.6 in a puffer type arrangement. The cooperating contacts are surrounded by a nozzle and an upstream and a downstream piston, which are moved by a constant force-operating mechanism, move liquid SF.sub.6 between the cooperating contacts when they separate, in order to interrupt the arc between the contacts. The interrupter requires a relatively low volume of SF.sub.6 and a constant pressure is generated in the liquid during interruption. The interrupter ratings are adjusted by varying the differential pressure across the nozzle, and by changing the base-operating pressure.
摘要翻译：高压，高功率断路器使用液体SF6，采用吹气式排列。配合的触点被喷嘴和由恒定的力操作机构移动的上游和下游活塞包围，当它们分离时，液体SF6在配合的触点之间移动，以便中断触点之间的电弧。中断器需要相对较小的SF6体积，并且在中断期间在液体中产生恒定的压力。通过改变喷嘴上的差压以及改变基准工作压力来调节断路器额定值。
