摘要： A high-voltage switch contains two contact members, which can be moved relative to one another along an axis, a nozzle for blowing out a switching arc with quenching gas, and a stationary direction-changing transmission, which is connected to the nozzle and to the second contact member. The nozzle has a hollow insulating body, and a metallic annular body which is arranged at a blowing-out end of the nozzle, is connected in a formfitting manner to the insulating body, and supports an input or output drive element of the direction-changing transmission. This switch can be manufactured easily and at low cost, and provides good mechanical and electrical characteristics. The annular body has a concentrically arranged intermediate ring, which causes the form fit with the insulating body, and a ring, which is pushed onto the intermediate ring and is attached to the intermediate ring, for supporting the input-drive or output-drive element.

摘要： The disclosure relates to an electrical switching device, e.g., a generator circuit breaker, and to a method for improved switching-gas cooling. Gas jets are formed by a nozzle body in the exhaust area, are directed against a baffle wall and are swirled. The baffle wall is a component of the switching chamber enclosure and has a high thermal capacity and/or thermal conductivity, so that the switching gas vortices produce a highly efficient switching gas cooling on the baffle wall by turbulent convection. Exemplary embodiments relate inter alia to the design of the baffle wall and of the nozzle body. Advantages include: protection of the switching chamber enclosure against hot gases, improved switching gas cooling, and increased breaking capacity.

摘要： The gas circuit breaker has a configuration such that a stationary contact section and a movable contact section are arranged in an arc-extinguishing gas sealed container, to face each other, and the movable contact section includes a hollow operating rod having an exhaust hole at its rear portion, a movable cylinder arranged around the rod, a hollow movable arc contact provided on the movable cylinder and an insulating nozzle surrounding the movable arc contact. The movable contact section further includes a stationary piston portion insertable/removable inside the movable cylinder, and the space formed by the movable cylinder and the current collecting cylinder fixed to the stationary piston portion is partitioned by a parting plate into a thermal pressure elevation room space at front side and a compression room space at rear side. During the electrode opening operation, the compression room space is compressed by the interaction between the movable cylinder and the piston portion, thus increasing the pressure in the space, and the speed of the movement of the operating rod is slowed down just before the completion of the electrode opening operation.

摘要： The gas-blast circuit breaker has passages in the pump piston which connect the pump space to the arcing space surrounding the quenching tube and to the surrounding space located within the circuit breaker housing. These passages are held closed during switching-off and open during switching-on by valve devices. For this purpose, in one embodiment the pump piston is used as a valve seat and an annular disk is used as a valve body which is common to the first valve and to the second valve, the first valve controlling the passage between the pump space and the surrounding space, and the second valve controlling the passage between the pump space and the arcing space. When switching-off large currents, the piston is subjected to an overpressure in the switching-off direction, which overpressure is produced by switching gas flowing into the arcing space, in order to support the drive. The valves are prevented from opening due to the pressure in the pump space. During switching-on, the pump space is enlarged and the arcing space is reduced in size, causing the annular disk to be raised off the pump piston against the spring prestressing it by means of the reduced pressure in the pump space and the overpressure in the arcing space. Thus, the pump and arcing spaces are able to communicate with the surrounding space and to ensure pressure equalization without the drive having to apply more energy during switching-on than in the case of a circuit breaker without an arcing space.
