PURPOSE:To enhance the cooling effect, to reduce noise and to reduce the floor area of a gas insulated transformer by a method wherein the heat transfer rate on the insulating gas side and the air side of the self cooled radiators of the gas insulated transformer is enhanced. CONSTITUTION:Self cooled radiators 80 of the plural pieces are arranged in parallel and facing mutually on both the sides of right and left of an upper part header pipe 12 at the upper part of a transformer tank 10. The upper part connecting pipes 80a and the lower part connecting pipes 80b of the radiators 80 are connected removal freely to an upper part header pipe 12 and lower part header pipes 16, 18 respectively through flanges. A shielding hood 105 is made to hang down on both the sides and in front and in rear of the radiators 80, and the whole of the radiators are covered from the upper part by the hood 105. The hood 105 thereof is connected to the ventilating hole 103 of the partition wall 101 of a transformer chamber 100 through an air duct 106. |
