Abstract

The switchgear has a flow pipe with an exhaust duct (3) extending from a sink hole (4) towards an opening (18), along a lateral wall (11), where the duct has a constant or crescent section. The opening is equal to the section of the duct and is placed opposite to electrical contacts of an opening volume (35). Gas present in an exchange space is injected into the volume via the duct, where the gas is cooled while circulating in the duct.
