剛性に大きく影響される。 In the transformer configured as described above, the deformation of the tank 2, especially around the dome-shaped cover 3, due to the vacuum external pressure when insulating oil is injected is shown in Fig. 4 by the two-dot chain line A.
Shown below. 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.

それもある。 Therefore, in order to secure the insulation distance between the transformer main body contents 1 and the peripheral wall of the transformer tank 2, it is necessary to increase the internal dimensions of the tank or bend the reinforcing beam 7 welded to the dome-shaped cover 3. This may lead to an increase in the amount of insulating oil or the weight of the transformer tank. Furthermore, the packaging dimensions and height of the transformer configured in this way when transported are:
The H dimension in Figure 6 is the sum of the internal height of the transformer tank 2, the height of the reinforcing beam 7 welded to the dome-shaped cover 3, and the height of the reinforcing beam 9 welded to the bottom plate 6. An increase in the bending rigidity of the reinforcing beam 7 welded to the dome-shaped cover 3 may lead to an increase in the dimensions and height of the package for transportation, which may make transportation impossible.

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 is the same as that of the conventional type, the amount of deformation can be suppressed to about 60%. Therefore, the bending rigidity 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 compressed by about 20%. Therefore, it becomes possible to compress the size and height H of the transportation package.
