PROBLEM TO BE SOLVED: To improve a thermal load capacity of a generator switch, in electrical equipment for feeding and/or switching a large current and/or high voltage. SOLUTION: In the vicinity of a protective enclosure cover 3a of generator switches 20, 21, 22, radiation plates 5, 50, 51, 52 have at least one flexed metal sheet 50a. This sheet is used for feeding the stream along the protective enclosure cover. A typical execution mode includes the radiation plate electrically further thermally insulated from a housing 3, the radiation plate making structures 51a, 51c for guiding air on an inner surface 5a deflect in a horizontal direction, the flexed metal sheet with an inclined part lined up in a region 30a flattened on the protective enclosure cover, and the flexed metal sheet toward a cooling element 6 on the protective enclosure cover.

PROBLEM TO BE SOLVED: To provide a method of diffusing a heat loss from an internal conductor and to provide a circuit breaker. SOLUTION: The circuit breaker (20R, 20S, and 20T) having elongated internal conductors (21R, 21S, and 21T) and outer conductors (22R, 22S, and 22T) like a housing has at least one heat pipe (1), extending from this inner conductor (21R, 21S, and 21T) to outer conductors (22R, 22S, and 22T) and having an insulating hollow object (5) for forming an electric insulating gap. This heat pipe (1) has a flexible deformable part (9). This heat pipe (1) can pass along the inside of a support insulator (24), which supports the inner conductor (21R, 21S, and 21T). In addition to a working medium, the heat pipe (1) contains an auxiliary gas which produces dielectric strength, strengthened at a low temperature. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
A heat pipe (1) carries off heat-loss in an inner conductor (21) and extends from the inner conductor as far as an outer conductor (22). It also has an insulating hollow body (5) to form an electric insulating section (7). The heat pipe can run in an insulator (24) to support the inner conductor. An independent claim is also included for a method for cooling a heavy-duty circuit breaker's inner conductor stretched as an oblong and surrounded by an outer conductor in the form of a casing.
