Filed: 1990-11-27
Abstract: PURPOSE:To improve cooling characteristics of an external cooling device by providing metallic heat radiators to an upper gas piping of a self-cooling type gas-insulated transformer in such a manner that the radiator becomes vertical to the ground. CONSTITUTION:A plurality of metallic heat radiators 9 are provided with adequate intervals to the upper gas piping 6 provided horizontally in such a manner that these radiators become vertical to the gas piping and the ground. In the case the upper piping 6 is inclined, the heat radiators 9 are provided in the desired angle for the piping but vertically to the ground considering the circulation of the external air. Therefore, the heat is radiated externally by the heat radiators 9 from the upper piping 6 having a high cooling efficiency due to the random flow of the insulating gas 4 and moreover the heat radiators 9 accelerate circulation of heated air. Thereby, the cooling efficiency can be improved.
