A separating wall for dividing a heating volume of a power circuit into a first sub-volume and a second sub-volume. The separating wall is formed with at least one wall opening which allows a flow of gas between the sub-volumes. The wall opening has an aerodynamically active opening surface based on a pressure difference between a pressure in the first sub-volume and a pressure in the second sub-volume.

Dividing a heating volume of a power circuit

An interrupter unit for a circuit breaker includes a gas-insulated housing, which is fillable with a quenching gas, and a gas-guiding structure, which is disposed in the housing and has a guide tube and at least one diverting element. The guide tube extends in tubular manner about a longitudinal axis of the interrupter unit in order to guide hot gas, which is created in an electric arc region of the interrupter unit by the heating of quenching gas by an electric arc, away from the electric arc region. The at least one diverting element is configured to set hot gas exiting from the guide tube in a circular flow running around the longitudinal axis.

Interrupter unit for a circuit breaker

A high-voltage power switch, preferably with a dead tank design, contains: a switching unit that has a switching device and an actuation element that is axially movable in relation to a longitudinal axis of the switching device to actuate the switching device and a closing resistor unit that has a closing resistor arrangement and an adjusting element that is axially movable in relation to a longitudinal axis of this closing resistor arrangement to actuate the closing resistor arrangement. The actuation element is coupled to the adjusting element in order to move the latter. Accordingly, the longitudinal axis of the switching unit and the longitudinal axis of the closing resistor unit are spaced apart, and the actuation and adjusting elements are coupled by a coupling device of the high-voltage power switch.

High-voltage power switch with closing resistor arrangement

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.
