Abstract: 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.

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.

Abstract: A switchgear includes an interrupter unit. The interrupter unit is provided with first and second switching contact pieces that are movable relative to one another. A switching-gas duct that runs through the interrupter unit originates at an arc gap in which an electric arc can burn. The duct connects the arc gap to the surroundings of the interrupter unit.

One of the elements is a first member which is braced at the end similar to a pipe joint and which has a free end that projects in the direction of the arc gap.
