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 switching chamber for a heavy-duty circuit breaker which can be filled with a quenching gas has a first arcing contact piece (1) and a second arcing contact piece (2), of which at least one (1; 2) can be moved by means of a drive. An arc (4) may burn between the contact pieces (1, 2). A heating chamber (11) is used for temporarily storing quenching gas heated by the arc (4). An insulating nozzle (5) has a throat (6), which is used for guiding a quenching gas flow and is connected to the heating chamber (11). During an opening operation, a maximum relative speed v12,max of the two arcing contact pieces (1, 2) in relation to one another is reached which is at least 1.3 times as great as a relative speed v12,c of the two arcing contact pieces (1, 2) which is required for capacitive switching. In the case of a single-chamber heavy-duty circuit breaker, in particular the following applies for the maximum relative speed v12,max: v12,max ≧23×UN·p·f/(Ecrit·p0), wherein UN is the rated voltage of the heavy-duty circuit breaker if the latter is in the form of a single-chamber heavy-duty circuit breaker, p is the pole factor of the heavy-duty circuit breaker, Ecrit is the threshold field strength for discharges of the quenching gas, and p0 is the filling pressure of the quenching gas, and f is the system frequency for which the switching chamber is designed.

摘要： A gas-blast circuit breaker is disclosed which includes a first contact and a second contact which can move relative to one another along a longitudinal axis. A blowout volume is arranged around the first contact. The blowout volume can be connected via a gas channel to an arc zone, in order to blow out an arc which is struck when the first contact is disconnected from the second contact. The blowout volume can be bounded radially on an outside by a separating element which separates the blowout volume from a low-pressure area. A flow opening, which allows a gas exchange, can lead in a radial direction from the low-pressure area into the blowout volume.

摘要： The switching chamber is intended for a gas-insulated high-voltage switch. It contains a housing filled with insulating gas and a contact arrangement held in the housing. The contact arrangement has, in a coaxial arrangement, the following components: two switching pieces, which are capable of being moved relative to one another along an axis, with in each case one arcing contact and in each case one tubular conductor containing a rated current contact, an insulating nozzle, and a compression apparatus with a fixed piston and a cylinder. A moveable tubular conductor of the two tubular conductors forms the wall of the cylinder, is electrically conductively and rigidly connected to one of the two arcing contacts via a base of the cylinder and bears the insulating nozzle.
