Electrical switchgear with improved cooling

A switchgear 1 comprises a switchgear housing 2, a number of busbars L1-L3 and a number of disconnectors 3a-3c within the switchgear housing, wherein the disconnectors are arranged in the course of the busbars. The switchgear further comprises a disconnector housing 4, which is arranged within the switchgear housing and encompasses at least the disconnectors. The disconnector housing has at least one bottom opening A, B, C and at least one top opening D, E allowing an air flow G based on thermal convection from the at least one bottom opening to the at least one top opening via said disconnectors. The dimensions of the disconnector housing and the openings may be chosen to generate a chimney effect through the disconnector housing to facilitate cooling of the disconnectors and other components accommodated by the disconnector housing.
