Arrangement comprising a low voltage power switch and a switching gas damper provided with a carrier element and used for the low voltage power switch

摘要

A switching gas damper is for low voltage power switches, especially for low voltage power switches which can be inserted into low voltage switching installations. The switching gas damper is arranged above an arc extinguisher of the low voltage power switches and includes at least one inlet for switching gases and at least one outlet for damped deionised switching gases. The switching gas damper is provided with a carrier element which can be arranged directly adjacent to the arc extinguisher and can be fixed to a housing receiving the low voltage power switch. The carrier element forms at least one receiving chamber for a flow element creating a flow resistance for the switching gases, and the at least one receiving chamber can be closed by at least one closing element fixing the at least one flow element. The carrier element forms the at least one inlet and the at least one closing element forms the at least one outlet.
