HIGH-VOLTAGE BUSHING, METHOD FOR COOLING BUSHING WIRE AND POWER DISTRIBUTION SYSTEM COMPRISING SUCH BUSHING

摘要

FIELD: electricity.SUBSTANCE: high-voltage bushing (1) comprises an elongated electric wire (2), an insulating sleeve (3), a surrounding wire (2), and a cooling facility for wire cooling (2). The cooling facility comprises at least one cooling element (7, 9), stretching along a section of a wire length (2) and thermally connected with the wire (2).EFFECT: sufficient cooling of an electric high-voltage bushing without excessive increase of load at its wire.20 cl, 3 dwg
