Abstract
A high-voltage switch has a metal container filled with insulating gas, and a quenching chamber installed in the container. The quenching chamber contains a housing which is aligned along an axis, an arcing contact arrangement which is held in the housing, an exhaust volume which is bounded by the housing, and an outlet channel which is passed through the wall of the housing for exhaust gases. The outlet channel opens with a mouth section which is aligned predominantly axially into the container. The mouth section is bounded on the inside by a tubular section of the housing and on the outside by a tubular housing attachment which surrounds the housing section at a distance from it. An electrically shielded edge which is passed in an annular shape around the axis is arranged on one end face of the housing attachment on which edge a flow, which emerges from the outlet channel of the exhaust gases is detached from the housing attachment.
