Claims

[Scope of utility model registration request]

(1) One tank is filled with insulating oil, and the tank is oil-tightly partitioned by a partition wall at the top so that the insulating oil can communicate with the main body, each of which is equipped with an iron core and winding of an oil-filled induction electric device. The tank portions partitioned by this partition wall can be supplied with oil and drained from each other, and when the tank portion on the storage side of the tap changer is drained, the upper end of the winding is In an oil-filled induction electric appliance arranged so as not to be exposed to insulating oil, a siphon is provided in the partition wall that has an oil passage communicating with each of the tank parts and each opening opens downward; The opening of the siphon on the side where the tap changer is stored is located above the opening on the side where the tap changer is stored,
An oil-filled induction electric appliance characterized in that it is arranged at a position above the upper end of the winding.

(2) Utility model registration Claim In the oil-filled induction electric appliance according to claim 1, the top of the oil passage of the siphon is located below the oil level where the insulating oil filled in the tank portion communicates with each other beyond the partition wall. An oil-filled induction electric appliance characterized by being located at. □(3) Scope of Utility Model Registration In the oil-filled induction electric appliance according to claim 1, the top of the oil passage of the siphon can close the communication hole that communicates with the inside of the tank and the core communication hole when draining oil. An oil-filled induction electric appliance characterized by being equipped with an air vent valve.
