Abstract
A compact earthing switch (') is provided by a mounting lid () of the gas-insulated switchgear assembly () having a concave physical volume () which extends the gas chamber () and by the earthing switch fixed contact () being mounted on an inner side () of the mounting lid () and being arranged at least partially in the physical volume () of the mounting lid (). Exemplary embodiments relate, inter alia, to: an essentially cylindrical mounting lid (); an earthing switch fixed contact () having a physical length (L) which is smaller than an axial physical depth (T) of the physical volume (); and a large diameter (D) of the mounting lid () for simplified mounting and maintenance of active parts) in the switchgear assembly (). Advantages include: the compact design for the grounding device the ability of the earthing switch fixed contact () to be ready-mounted on the mounting lid (); and the integration of the earthing switch fixed contact (), which is integrated in the mounting lid (), in a combined disconnector/earthing switch (′).
