Claims

[Scope of utility model registration request]

(1) The contents of electrical equipment and insulating oil are stored inside the tank, and this insulating oil is sent to the radiator through the upper oil pipe installed at the top of the cover, and the insulating oil cooled by the radiator is passed through the lower part. In oil-filled electrical equipment, where the heat generated in the electrical equipment body is cooled by being circulated into the tank via oil pipes,
°゛A tank-side upper oil pipe is provided on the upper side of the tank, and this upper oil pipe is connected to the upper oil pipe of each radiator through a common oil pipe, and this common oil pipe is fixed to the tank reinforcing material via a connecting metal fitting. On the other hand, there is provided a radiator characterized in that a cover reinforcing material is provided on the cover, this cover reinforcing material is fixed to a common oil pipe by a connecting metal fitting, and the common oil pipe is integrated with the cover and the tank reinforcing material. Oil-filled electrical equipment.

(2) Utility model registration claim No. 1 in which the connecting hardware on the cover side and the connecting hardware on the tank side are constituted by separate members.
Oil-filled electrical equipment equipped with a radiator as described in Section 1.
