要であつた。 FIG. 1 is a top view of a conventional transformer with the lid removed. The main body 1 consisting of an iron core, windings, etc. is housed inside a tank 3 along with insulating oil 2.
Cable box 4 is installed in the center of the long side of tank 3.
A cooler 5 is connected to the tank 3 through a connecting pipe 6 on both sides of the cable box 4, and the insulating oil 2 flows into and out of the cooler 5 from inside the tank 3 through the connecting pipe 6 to cool the main body 1 inside. I'm starting to do that. The side plate of the tank 3 has a structure in which four sides are formed by a long side side plate 3a and a short side side plate 3b, and both ends of the short side side plate 3b are slightly longer than the tank width and protrude in the tank width direction. In addition, if the number of panels in the cooler is large, the weight of the cooler is heavy, so the thickness of the side plate 3a on the long side may be increased in consideration of transportation, or the thickness of the side plate 3a on the long side may be increased, or the tank It was necessary to provide a reinforcing structure such as supporting the cooler 5 from the tank reinforcing member 3c to the cooler support fitting 7 on the side plate 3a of the tank.

がむだであつた。 In a transformer with such a conventional structure, the internal dimensions of the tank 3 are determined from the dimensions of the main body 1 , the required dimensions L1 for the internal structure, and the necessary dimensions for installing the cooler 5, cable box 4, etc. Of the required external structural dimensions L2 determined from the dimensions,
Determined by the larger of the two dimensions. tank 3
Since insulating oil 2 is sealed inside, if the required dimension L 2 of the external structure is larger than the required dimension L 1 of the internal structure, the amount of insulating oil equivalent to L 2 - L 1 will be wasted. It was hot.

ンジ部である。(Example) The present invention will be described below with reference to an example shown in FIG. In FIG. 3, the same parts as in FIGS. 1 and 2 are given the same reference numerals. In Fig. 3, the side plate of the tank 3 has four sides consisting of a long side side plate 3a and a short side side plate 3b, and both ends of the long side side plate 3a are made slightly longer than the tank length so that they extend in the tank length direction. The tank 3 has a protruding structure, and the long side dimension of the tank 3 is the required dimension L 1 for the contents structure determined by the dimensions of the contents main body 1 and the required insulation dimensions, and the cooler 5
The tank 3 is constructed by making the side plate 3a on the long side to which the cable box 4 is attached protrude beyond the side plate 3b on the short side, and the communication pipe 6 of the cooler 5 is arranged at the position of the side plate 3b on the short side. It is set up. In this way, since the side plate 3a on the long side is structured to protrude, there is no need for a margin for welding the connecting pipe 6 (dimension l in FIG. 1 of the conventional example), and the length of the tank 3 is reduced by that amount. The size is smaller and the amount of insulating oil can be reduced. In addition, since the side plate 3b on the short side is provided on the back side of the mounting position of the connecting pipe 6, the side plate 3b on the short side serves as a reinforcing member in the vertical direction of the mounting portion of the connecting pipe 6, and the tank reinforcing member 3b, which is conventionally installed,
Reinforcement structures such as c and cooler support fittings 7 are no longer necessary, and there is no longer a need to increase the thickness of the side plates 3a and 3b. The communication pipe 6 and the inside of the tank 3 are communicated through a communication hole 8 (a semicircular hole may be used) drilled in the tank side plate 3a, as shown in the cross-sectional plan view of FIG. 4 and the side view of FIG. Align the inner diameter of the pipe 6 and weld the welded part 9.
It sticks to the surface. Although the communication hole 8 is not perfectly circular, it has a sufficient area for the required amount of oil to pass through, so that no cooling problem occurs. 10 is a flange portion.

要もなくなり、タンク重量の軽減となる。(b) The side plate on the short side reinforces the connection pipe attachment part of the cooler, eliminating the need for tank reinforcing members and cooler support metal fittings, and eliminating the need to increase the thickness of the side plate, reducing the tank weight. It will be reduced.
