Cooled housing for transformer and switchgear

摘要

The housing accommodates a transformer (2) and switchgear (3), and has cooling equipment (4) with one or more tapered cooling channels. The housing is equipped so that hot gases and / or vapours which originate during operation in, or close to, the switching gear (3), can pass through the channels in the direction of tapering. The cooling equipment may be made mainly from concrete, and may be arranged so that the gases and / or vapours must pass through it before they can enter the transformer space. It may have tapered channels which are arranged one behind another in the direction of flow of the gases and / or vapours.
