An electrical switching device is provided for interrupting an electrical connection. The device has a switching chamber and two contact pieces being arranged directly in the switching chamber or in an encapsulated housing arranged in the switching chamber and configured to be gas-tight in relation to the switching chamber. The contact pieces are movable relative to each other to bring about a switching action. A fluid insulation medium is also provided, which is arranged in the switching chamber or in a storage volume which can be connected to the switching chamber. The switching chamber or the storage volume has an outlet for letting out the fluid insulation medium. A filter is provided at or adjacent to the outlet, the filter configured to filter gaseous components of the insulation medium, or the reaction products thereof, conducted through the outlet.

Electrical switching device

An insulating medium for an electric energy transmission device is a fluid at room temperature and atmospheric pressure and has at least the following components &#x2265;50% by volume to &#x2264;98% by volume of synthetic air, and &#x2265;2% by volume to &#x2264;50% by volume of an organic fluorine compound. An electric arc extinguishing medium and a fluid-insulated electric energy transmission device are also provided.

Insulating medium for an electric energy transmission device

An arrangement includes an encapsulation housing and a fluid-insulated phase conductor which is disposed within the encapsulation housing, so that an electrically insulating fluid flows around the phase conductor. The phase conductor has a plurality of electrically parallel conductor tracks, at least in some sections. The conductor tracks mutually support each other.
