Abstract

An electric switchgear includes an interrupter unit having a first connecting line and a second connecting line. The interrupter unit is disposed inside a fluid-tight encapsulating housing that is filled with an electrically insulating fluid. The interrupter unit is further surrounded by a shielding housing in at least some sections. The first connecting line has a flow channel for the fluid. A first outlet opening of the flow channel leads to the shielding housing and a second outlet opening leads to the exterior of the shielding housing.
