PURPOSE:To form a sealing structure, and to increase the rated current value of a bus by covering the heater of a heat pipe with an insulating layer, abutting it against a horizontal bus and providing a heat sink unit of the pipe out of a panel. CONSTITUTION:Heat generated at a horizontal bus 1 is conducted through 3-phase simultaneous insulators 6 attached in close contact to the side of the bus 1 to the heater 7a of a heat pipe 7. This heat is dissipated from the fin of a heat sink unit 7b at a ceiling out of a panel by means of thermal conduction of the pipe 7. |
