STATIONARY INDUCTION APPARATUS

PURPOSE:To improve economical efficiency by providing the front or its part of the tank of the main part of equipment of a stationary induction apparatus with a heat insulating material. CONSTITUTION:The surface of the body part of the tank 1 of the main part of equipment of a gas-insulated transformer excepting terminal outlets 3, 4, an interphase connection bus 5 and the tank panel boards of the main part is covered with a noncombustible heat insulating material 2 which is then fixed by the use of a flange 7. Further, a heat exchanger 6 is provided in the vicinity of the tank 1 of the main part of equipment of the gas-insulated transformer. When the outside of the tank 1 of the main part of equipment is covered with the heat insulating material 2 in this manner, the dissipation of heat generated by the gas-insulated transformer into a building is reduced so that the design of a ventilation duct can be rationalized and the height of a story can be reduced according to the required height of the equipment. Also, because the gas-insulated transformer has no conservator unlike an oil-filled transformer, the height of the building can be made low. Further, the heat generated by the gas-insulated transformer is dissipated out of the building via the heat exchanger 6. Thus, it is possible to improve economical efficiency.
