ABSTRACT:
A high-voltage switching device for gas-insulated switchgear has a gas-filled metal housing, a conducting path in the metal housing and at least two series-connected switching points with movable contact pieces which are actuated by a common drive mounted on the metal housing. The conducting path forms an angle with at least one of the switching points respectively arranged on each leg of the angle, the device thereby requiring less space in the case of both vertical and horizontal installation.
