Description

technical field

[0001] The invention relates to a structural unit for receiving at least one element for absorbing or damping hot escaping gases caused by arcs in a high-voltage or medium-voltage electrical functional unit, in particular a high-voltage or medium-voltage switchgear. Background technique

[0002] Document DE 196 45 304 C2 discloses a bushing as a damping element which is arranged at the end of a pressure-relief channel of an otherwise closed medium-voltage switchgear. The damping element in the bushing is a metal deflector plate, which is fixed offset in the path of the exhaust gas as a gusset.

[0003] Another structural unit is known from DE 198 58 952 C1. In this structural unit there is a defined outflow channel for the hot gases and a chamber is formed there, which is filled up to 70% of its volume with loose, preferably spherical damping bodies. The damping body consists of plastic and is coiled by the passing gas, thereby cooling, deionizing and dampi...
