Electrical switching device

A method for releasing a fluid insulating medium from a switching device, which comprises the following method steps of:

• a) providing the switching device to contain:
• a switching chamber;
• two contact pieces disposed directly in the switching chamber or in an encapsulation housing disposed in the switching chamber and configured in a gas-tight manner vis-à-vis the switching chamber, the contact pieces being movable relative to one another for an execution of a switching action;
• the fluid insulating medium disposed in the switching chamber or in a storage volume connected to the switching chamber, the switching chamber or the storage volume having an outlet for releasing the fluid insulating medium;
• and
• a filter disposed on or adjacently to the outlet and configured to filter out gaseous constituents of the fluid insulating medium or reaction products thereof, which are conveyed through the outlet, the filter configured for releasing the fluid insulating medium exiting the filter into an environment;
• b) conveying the fluid insulating medium through the outlet;
• and
• c) conveying the fluid insulating medium which exits the filter into the environment.
