Abstract
A switching installation includes a gas tight housing with at least one wall part. An input conductor disposed in the housing is configured to carry an input voltage. An insulation is arranged around the input conductor so as to insulate the input conductor from the housing. A short-circuit device is changeable from a first condition, in which the insulation is insulating the input conductor from the housing, to a second condition, in which an electrical short circuit connection is created through the insulation between the input conductor and an auxiliary connection. An actuator is coupled to the at least one wall part of the gas tight housing and is configured to actuate the short-circuit device as a result of movement of the wall part caused by a pressure increase in the housing. A threshold device is configured to provide a preset threshold in the actuator.
