COOLED ELECTRICAL COMPONENT

摘要

A coolable electrical component having a housing (1) filled with insulating gas, and a conductor (2) of hollow cylindrical construction causing a high voltage, arranged in this housing (1). Through the interior space (7) of the conductor a coolant is circulated. The electrical component occupies a smaller space and yet allows increased current load capacity. This is achieved by providing a high-pressure tank (19) extending in the longitudinal direction of the conductor (2) in the interior space (7) thereof. The tank is connected to a gas liquefaction installation by means of outlet orifices (18) perforated in its wall at regular intervals thereof. Such a componet may preferably be a tubular gas cable or a component of a gas-insulated, metal-encapsulated switchgear.
