ンクが公知である。In recent years, in substations and underground facilities for buildings in urban areas, electrical facilities such as transformers have been made non-combustible and flame-retardant due to the necessity of disaster prevention. For this reason, the so-called use of an inert gas such as SF 6 gas or an inactive gas such as fluorocarbon, CFC or the like in addition to a conventional mineral oil as an insulating and cooling medium for a large-capacity transformer, reactor, etc. A gas insulation type has been developed. It is also necessary to design the hermetically sealed container for accommodating the gas-insulated induction machine body so that the amount of expensive insulating medium is reduced and the size thereof is reduced. On the other hand, from the viewpoint of insulation strength and cooling performance, it is desirable that the pressure of the insulating fluid such as SF 6 gas is as high as possible, and therefore the closed container is required to have a structure capable of withstanding high-pressure gas. By the way, in a conventional tank structure such as an oil-filled transformer, the plate thickness and the reinforcing member become large, so that a rational tank structure is desired. Japanese Patent Laid-Open No. 61-30015 discloses a related one, and a spherical or cylindrical tank is known.

ク上部に比べて補強されていて堅牢である。That is, the standard end plate 7 (see FIGS. 6 and 7) is cut at the center position. A curved plate part 8 (see FIGS. 10 and 11) manufactured by a roll press is welded between two standard end plates 7a (see FIGS. 8 and 9) to form a turtle shape. An end plate material 9 (see FIG. 12 and FIG. 13) which is the end plate of the above is formed. The end plate material 9 thus formed was welded to the upper and lower sides of the tank side plate 6 having an oval cross section. By doing so, it is possible to manufacture a tortoise-shaped tank (see FIGS. 1 to 3) without using a dedicated press mold and by selecting arbitrary specifications. It becomes easy and the number of machining can be greatly reduced. Further, unlike the conventional spherical or cylindrical tank, the space between the induction body 1 and the tank can be optimized, and the space factor of the induction body 1 can be made most rational. As a result (see FIGS. 4 and 5), the amount of the expensive insulating medium used can be significantly reduced, and it can be put to practical use in terms of price. In addition, since the tank has the end plate structure, the pressure of the insulating medium can be increased to about 5 kg / cm 2 , the insulation distance of the induction electric machine can be shortened, and the tank can be made compact and lightweight. Further, in this embodiment, the tank body 2 is formed by providing the tank pocket 10 on the tank side plate 6 in the middle of the box-shaped reinforcing beams 3 arranged at least at two upper and lower positions, and the upper and lower tanks are weak points as a tank. Since the flanges 4 and 5 are arranged on the lower side of the tank main body 2, a tank having a balanced rigidity as a whole can be manufactured. By the way, in the lower part of the tank, the main body 1
Since a beam for supporting and fixing the tank and a reinforcing beam for installation are provided, it is reinforced and robust compared to the upper part of the tank.
