Quick-action earthing device for gas-insulated switching installations

摘要

A quick-action earthing device for gas-insulated switching installations. In the case of gas-insulated switching installations, when the insulation fails and interference arcs occur, it is necessary to earth the installation as quickly as possible in order to limit the damage.
<??>The invention makes available a quick-action earthing device which causes earthing immediately and in the case of which the gas pressure wave which occurs in the case of an interference arc forces a part (6), which is constructed like a piston and is connected to a switching pin (7), into a position which produces the earthing.
