In general, oil tanks for oil-filled appliances such as transformers are constructed with the long side plates 1 facing each other, and the short side plates 2 being orthogonal to both end positions of the long side plates 1, as shown in FIGS. 3 and 4. It is fixed in contact with the inside of the side plate 1, and a bottom plate 3 is attached to form a box shape. Then, connecting oil pipes 13 are installed in series to connect a plurality of radiators 12 above and below the long side plate 1. If more radiators are required, the upper part is placed outside the short side plate 2. A common oil conductor is provided which also serves as the bushing pocket 4, and a square tube or the like is protruded from the outside of the short side plate 2 at the lower part to form a common oil conductor 5, and an upper common oil conductor and bushing pocket 4 is provided. Attach the bushing 6 and L-shaped cable box 7 to the bushing 6, connect the cable 8 to the bushing 6, and attach the L-shaped cable support seat 9.
A lower cable penetration part partition plate 10 was installed, and a cover 11 was fixed to the front surface of the cable box 7 with bolts to seal it, thereby forming an oil tank and a cable box. Note that 15 is a reinforcing stay for the oil tank. This structure not only increases the longitudinal dimension of the entire electrical appliance including the cable box 7, but also requires the production of the bushing pocket 4 and the lower common oil conductor 5, the installation work to the oil tank, the production of the cable box 7, and the production of the bushing pocket 4 and the lower common oil conductor 5. There was a drawback that the installation work to the single pocket 4 required materials and man-hours. Furthermore, in the case of a low-noise transformer installed with a soundproof wall 14 shown by a two-dot chain line in FIG.
There was a large amount of sound leakage from the 4 butting pockets and the 5 parts of the lower common oil guide, reducing the soundproofing effect, and the structure of the penetrating part between them and the soundproof wall 14 was complicated, resulting in the disadvantage of requiring materials and man-hours. . Incidentally, as a known example related to this example, there is Japanese Utility Model Application Publication No. 53-17749.
