    Abstract: The invention relates to an electrical switching device with a switching chamber (10), which comprises at least two arcing contacts (192, 192) movable in relation to each other and defining an arcing region (22) in which an arc (20) is formed during a current breaking operation, with the switching chamber (10) being filled with a switching medium (20) for arc quenching and for dielectrical insulation. The switching chamber (10) further comprises an exhaust volume (40, 62) fluidically connected to the arcing region (22) to allow the switching medium heated by the arc (20) to flow out of the arcing region (22) to the exhaust volume (40, 62), thereby transferring heat to a surface area of a metal component of the switching chamber (10). The device is characterized in that at least a portion of a surface contained in the switching chamber (10) is covered with a porous layer (72).

    Abstract: The gas-insulated HV switching device comprises a contact arrangement with two arcing contacts, one of which being designed as a contact tulip (21), an auxiliary nozzle (40) enclosing at least partially the contact tulip (21) and a tubular electrostatic shield (42), which protrudes along an axis (A) beyond a free end of the contact tulip (21). In order improve the switching performance of the switching device the tubular electrostatic shield (42) is electrically connected to the contact tulip (21) and is integrated in an electrical circuit comprising a current limiter (resistors 43, 44) and extending from the shield (42) through the current limiter to an end of the contact tulip (21) which is arranged opposite its free end.
