PROBLEM TO BE SOLVED: To provide a stationary induction electric device which is not affected by the inclination of a stationary induction electric device or the shaking of liquid level, and can detect leakage of liquid refrigerant well.SOLUTION: An electric device body is housed in a body tank 6, a gas chamber 2 having a gas space 7 above the body tank 6 is installed, and then the body tank 6 and gas chamber 2 are coupled by a coupling pipe 4. The body tank 6 is filled with liquid refrigerant 3, and filled with liquid refrigerant 3 and gas so that the liquid level, i.e., the contact surface of the gas space 7 and liquid refrigerant 3, is located in the gas chamber 2 or coupling pipe 4, and the liquid level detector 8 of a liquid level indicator is installed in the coupling pipe 4. |
