摘要： This hybrid circuit breaker has at least two series-connected arcing chambers which are operated by a common drive or by separate drives and are filled with different arc extinguishing media. The arc extinguishing and insulating medium in the first arcing chamber surrounds the second arcing chamber in an insulating manner. The aim is to provide a hybrid circuit breaker which can be produced economically and which has high availability. This is achieved, inter alia, wherein means are provided which always ensure that the movement of the first arcing chamber leads the movement of the second arcing chamber during a disconnection process, and that the movement of the second arcing chamber always leads the movement of the first arcing chamber during a connection process.

摘要： This hybrid circuit breaker has at least two series-connected arcing chambers which are operated by a common drive or by separate drives and are filled with different arc extinguishing media. Means are provided which ensure a sensible voltage distribution between the first and the second arcing chamber in the course of a switching process. At least one vacuum switching chamber having an insulating housing, is provided as the second arcing chamber. The aim is to provide a hybrid circuit breaker wich can be produced economically and which has high availability. This is achieved, inter alia, in that means are provided which ensure that the movement of the contacting arrangement of the first arcing chamber precedes the movement of the contact arrangement of the second arcing chamber during a disconnection process, and that the movement of the contacting arrangement of the second arcing chamber precedes the movement of the contact arrangement of the first arcing chamber during a connection process. The second arcing chamber is permanently bridged by a non-reactive resistor, which is in the form of a resistance coating applied to the inner wall or the outer wall of the insulating housing of the second arcing chamber.

摘要： An exemplary circuit breaker includes at least one arcing chamber that is filled with isolating gas, extends along a longitudinal axis, is designed to be essentially radially symmetrical, contains an arc area and has at least two power contact pieces. At least one of the power contact pieces is in the form of a moving or stationery tubular hollow contact, which is provided for dissipating hot gases from the arc area into a concentrically arranged exhaust body. A deflection device, which interacts with at least one opening in the hollow contact, is arranged on the side of the hollow contact facing away from the arc area, and radially deflects hot gases into the exhaust volume, which is connected through at least one second opening to an arcing chamber volume. An increased disconnection rating is achieved by providing at least one intermediate body between the hollow contact and the exhaust body.

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 heavy-duty circuit breaker contains a first moveable arcing contact piece and a second moveable arcing contact piece as well as an auxiliary drive for driving the second arcing contact piece. An arc may burn between the arcing contact pieces. The heavy-duty circuit breaker has a heating chamber for temporarily storing quenching gas heated by the arc and a throat for guiding a quenching gas flow, which throat is connected to the heating chamber by a channel. The throat can be blocked by one of the two arcing contact pieces, which is the blocking contact piece. The auxiliary drive is designed such that, during an opening operation, a movement direction reversal of the second arcing contact piece from a movement in opposite directions to a movement in the same direction of the two arcing contact pieces takes place, if the throat is no longer blocked by the blocking contact piece.

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.
