摘要： A gas circuit breaker 1 includes an insulation nozzle 23 that guides arc-extinguishing gas to an arc between a first arc contactor 21 and a second arc contactor 41 when a trigger electrode 31 becomes an opened state relative to the first arc contactor 21. The second arc contactor 41 has an opening 41a for spraying the arc-extinguishing gas, and the opening 41a is closed by the trigger electrode 31 in the first half of a current breaking action, and is opened by separation of the trigger electrode in the latter half of the current breaking action. An opening area of a first exhaust port 41b formed between the second arc contactor 41 and the insulation nozzle 23 for exhausting the arc-extinguishing gas is 0.2 times or more and two times or less of an opening area of the opening 41a of the second arc contactor 41.

摘要： An interrupter unit for a circuit breaker has two electrically conductive arcing contact pieces, which can be moved relative to one another along a switching path. An insulating nozzle has a nozzle channel through which the switching path runs. A heating volume is connected to the nozzle channel. A separating housing divides the heating volume into a cold gas region and a hot gas region. A cold gas duct runs through a nozzle channel end section of the nozzle channel and is connected to the cold gas region. A hot gas duct runs through the nozzle channel end section and is connected to the hot gas region.

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 puffer type gas circuit breaker has a piston, which is connected with a center shaft via a link mechanism. At an initial stage of an interruption operation, the link mechanism drives a puffer cylinder and the piston both in an interruption direction while maintaining an almost constant distance therebetween. Even when a pressure rise occurs in a compression chamber by the heat of an arc generated in accordance with opening between a fixed arc contact and a movable arc contact, the pressure rise does not become an operation counterforce to an operator. At a final stage of the interruption operation where the fixed arc contact is removed from a throat of an insulating nozzle, the link mechanism drives the piston in an almost stopped status.

摘要： A compressed gas interrupter comprises two contact assemblies each including at least one wear contact and one of which is mobile along an axis relative to the other, which is fixed. The mobile contact assembly is moved along the axis by an insulative maneuvering rod and has a gas compression chamber which, in the open position, communicates via an insulative nozzle with an expansion chamber. The compression chamber includes a piston attached to the hollow wear contact of the mobile contact assembly and which slides in a cylinder attached to the maneuvering rod, the cylinder delimiting the compression chamber with the piston and the nozzle. The hollow wear contact is mobile relative to the maneuvering rod. A system using balls immobilizes the hollow wear contact during initial travel of the maneuvering rod to open the interrupter and constrains the hollow wear contact to move with the maneuvering rod at the end of its travel.
