Claims

[Scope of Claim for Utility Model Registration] (1) Consisting of an electrical device, a tank that houses the electrical device, and a cooler that radiates heat generated by the electrical device to the outside, the tank has a non-condensing The lower header of the cooler is filled with a gas and a refrigerant whose vapor specific gravity is larger than that of the gas and which causes a gas-liquid phase change, and the lower header of the cooler is connected to the tank through a communication pipe, and the tank side end of the communication pipe is connected to the tank. An evaporative cooling type gas insulated electrical device comprising a deflection tube extending into a tank and movable in the vertical direction according to fluctuations in the liquid level of the refrigerant. (2) The evaporative cooling type gas insulated electrical device according to claim 1, which is characterized by having a float capable of floating in a liquid phase refrigerant at the tip of the deflection tube.
