へ導かれる。2. Description of the Related Art A gas-insulated transformer does not require an accessory such as a conservator at the top unlike an oil-immersed transformer, so that the upper space can be used effectively. For this reason, as shown in FIG. 2, a cooling device is installed in the upper space to reduce the installation area. That is, the winding 1 and the iron core 2
The cooling device 4 is installed above the tank 3 in which the insulating gas 5 is heated by the heat generated by the winding 1 and the iron core 2.
Is cooled by entering a cooling device 4 via a pipe 6 and guided to a lower portion in the tank 3 via a pipe 7 provided outside the tank 3.
