PURPOSE:To make incombustible, miniaturize and lighten a transformer by a method wherein an insulating gas is enclosed into a tank and a cooler, and the insulating gas is circulated by means of a blower. CONSTITUTION:A tank 8 and a cooler 9 are communicated by means of pipings 10a, 10b, and an insulating gas is enclosed into the tank 8 and the cooler 9. Heat generated in the tank 1 is transmitted to the insulating gas, forwarded to the cooler 9 by means of a blower 11 and thermally radiated into air. |
