Abstract

The switchgear (Z) is connected via pipelines (1, 2) to a heat exchanger (WT) in order to heat up or to cool the insulating gas. The heat exchanger (WT) is controlled by a pressure monitor (P) in order to maintain a particular pressure ratio between switchgear interior and the environment. If it is not sufficient to maintain the pressure by heating up insulating gas, a replenishing valve (3) is opened by a temperature monitor (T) at a particular temperature in order to replenish insulating gas. After the pressure has been reached, the replenishing valve (3) is closed again by the pressure monitor (P).
