ーム7の両端部と連結されている。The structure of a typical conventional transformer is shown in FIGS. 5 and 6. The transformer main body contents 1 are housed inside a transformer tank 2 together with insulating oil. The transformer tank 2 is composed of a dome-shaped cover 3 and a lower tank 4 consisting of a vertical wall 5 and a bottom plate 6. Reinforcement domes 7.8.9 are fixed to the dome-shaped cover 3, the vertical side wall 5, and the bottom plate 6 by welding, respectively, and the lower end of the reinforcing beam 8 welded to the vertical side wall 5 is fixed to the bottom plate 6. Both ends of the reinforcing beam 9 fixed by welding are fixedly connected by welding, and the upper end is connected to both ends of the reinforcing beam 7 fixedly welded to the dome-shaped cover 3 via seven runci.

ーム7の曲げ剛性に大きく影響される。In the transformer constructed in this way, the deformation of the tank 2, especially around the dome-shaped cover 3, due to the vacuum external pressure during insulating oil injection is shown by the two-dot chain line △ in FIG. That is, the amount of bulging deformation of the top portion of the dome-shaped cover 3 and the amount of concave deformation of the side wall 5 are greatly influenced by the bending rigidity of the reinforcing beam 7 welded and fixed to the dome-shaped cover 3.

This may result in an increase in the amount of insulating oil or the weight of the transformer tank. Furthermore, the dimensions and heights of the transformer constructed in this way in the state of transportation are determined by the inner dimensions of the transformer tank 2, the height of the reinforcing beams 7 welded to the dome-shaped cover 3, and the heights of the reinforcing beams 7 welded to the bottom plate 6. 6, which is the sum of the heights of the fixed reinforcing beams 9, and an increase in the bending rigidity of the reinforcing beams 7 welded to the dome-shaped cover 3 leads to an increase in the height of the package for transportation. , there is a risk that it may become impossible to transport.

Hを圧縮することが可能となる。Next, the effects of the present invention will be explained. The dome-shaped cover 3 has a reinforcing beam 7 whose upper side is horizontally formed and fixed by welding, and due to the rigidity of the corner part having a wide area of the reinforcing beam 7, its deformation is greatly suppressed by the vacuum external pressure during oil filling. Ru. The deformation situation with respect to the vacuum external pressure is shown by the broken line B in FIG. If the bending rigidity of the uppermost part of the reinforcing beam 7 welded to the dome-shaped cover 3 is the same as that of the conventional type, the amount of deformation can be suppressed to about 60%. Therefore, the bending stiffness of the beam is roughly proportional to the cube of the beam height, so if the same amount of deformation is allowed, the beam height can be reduced by approximately 20
% compression. Therefore, it becomes possible to compress the size and height H of the transportation package.
