Summary: | 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.
