    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: An apparatus (1) for heating an insulation fluid (10) in a medium-voltage or high-voltage switchgear (100) comprises an infrared source (3) which is adapted to emit infrared radiation (4) of at least one wavelength. Thus, at least one vibrational or rotational mode of at least one component (11) of the insulation fluid (10) is excited by absorption of at least a part of the infrared radiation (4), and condensation of the insulation fluid (10) is efficiently prevented by this direct heating of the insulation fluid (10). A closed loop temperature regulator (5) is used to heat only when required. A circulator (7) in a heating chamber (8) further provides for a mixing of the insulation fluid (10), thus preventing steep temperature gradients.
