Abstract
An insulating gas-filled disconnecting switch comprises a metallic container filled hermetically with an insulation gas, and a movable electrode and a stationary electrode disposed within the metallic container and electrically insulated from the latter. Means for guiding an arc possibly produced between both electrodes upon separation of the movable electrode from the stationary electrode positively toward a center portion of an opposite end of the stationary electrode, to thereby prevent the arc propagation toward the stationary electrode from reaching the metallic container from the stationary electrode.
