を緩和しうるようにしたものである。B. SUMMARY OF THE INVENTION The present invention relates to a tank for an oil-filled device in which a heat dissipation corrugated panel is welded to a side plate (hereinafter referred to as a corrugated tank). The welding angle with the fin portion is set to 95 ° to 135 ° so that stress concentration generated after welding and joining can be relaxed.
Ｃ．従来の技術 油入変圧器は四季の周囲温度の変化や機器の運転停止時

ンクの強度を確認している。C. Conventional technology In oil-filled transformers, oil expands and contracts due to changes in ambient temperature during the four seasons and temperature changes such as when the equipment is not operating, causing internal pressure changes. For this reason, in oil-filled transformers, a conservator is installed and an upper pressure-relief space is provided to mitigate pressure fluctuations and check the strength of the tank.

を有するようになっている。Further, as shown in FIG. 5, a corrugated panel 4 formed by continuously bending a thin steel plate in a wave shape to form a heat radiating fin 4b is provided on the side plate 2 of the tank by welding, and the corrugated panel 4 serves as a device. In the corrugated tank 1 of the oil-filled transformer that radiates heat, the corrugated panel 4 is designed to be easily deformed even with a minute pressure, and has a function of absorbing expansion and contraction of oil. There is.
Ｄ．考案が解決しようとする課題 かかる従来の波形タンクは圧力に対する強度に自ずと限

ｂ部分が側板２に対して直角（９０°）に溶接アされて
いるため、この部分が膨張、収縮による形状の急変部と
なって応力が極めて集中し易くし、波形タンクの強度上
の最大のネックとなっており、油洩れもこの部分より生
じ易かった。D. The conventional corrugated tank naturally has a limit to the strength against pressure, and in particular, the joint between the corrugated panel 4 and the side plate 2 due to welding is formed between the narrow portion of the corrugated panel 4 having the fin 4b and the fin. It is a seam of a wide area that does not have a fin 4
Since the b portion is welded at a right angle (90 °) to the side plate 2, this portion becomes a sudden change in the shape due to expansion and contraction, which makes it extremely easy for stress to concentrate and maximizes the strength of the corrugated tank. It became the neck of the oil, and oil leakage was more likely to occur from this part.
本考案はかかる実状に鑑みてなされたもので、タンクの
側板と波形パネルの溶接部の強度を向上しうるようにし
た油入機器のタンクを提供することを目的とするもので
ある。The present invention has been made in view of the above circumstances, and an object thereof is to provide a tank for an oil-filled device in which the strength of the welded portion between the side plate of the tank and the corrugated panel can be improved.
Ｅ．課題を解決するための手段 第１の考案は波形パネルのフイン部分の上面及び下面に
傾斜を設けて側板に対する波形パネルのフイン部分との

特徴とし、又第２の考案は第１の考案において側板と波
形パネルをタンクの内外の両側で溶接接合したことを特
徴とするものである。E. Means for Solving the Problems A first invention is to form an inclination on the upper surface and the lower surface of a fin portion of a corrugated panel and to weld the side plate to the fin portion of the corrugated panel at a welding angle of 95 ° to 135 °. The second invention is characterized in that, in the first invention, the side plate and the corrugated panel are welded to each other on the inner and outer sides of the tank.
Ｆ．作用 本考案によればタンクの側板に対する波形パネルのフイ
ン部分の溶接角度αが９５°〜１３５°となっているの
で、従来の溶接角度αが９０°となっているものに比し
て形状の変化が緩やかになるため、この溶接部における
応力の集中が緩和されてタンクの強度が増大する。F. Effect According to the present invention, since the welding angle α of the fin portion of the corrugated panel with respect to the side plate of the tank is 95 ° to 135 °, the welding angle α is smaller than that of the conventional welding angle α of 90 °. Since the change becomes gradual, the concentration of stress in the welded portion is relieved and the strength of the tank is increased.
溶接角度αは９０°より大きくなればなる程応力集中が
しにくくなるが、波形パネルのフインの面積が小さくな
り放熱器としての効果が下がるので、両者を兼ね備なえ
る角度として９０°〜１３５°の範囲とする。又溶接は
第２図のようにタンクの内外の両側で溶接することによ
り、溶接による接合部の強度は増大する。As the welding angle α becomes larger than 90 °, stress concentration becomes less likely to occur, but the fin area of the corrugated panel becomes smaller and the effect as a radiator decreases, so an angle that can combine both is 90 ° to 135 °. The range is. In addition, as shown in FIG. 2, the welding is performed on both the inside and outside of the tank, so that the strength of the welded joint is increased.

第１図のような波形タンクとしたものである。G. Example A corrugated panel 4 in which the upper and lower surfaces of the fins 4a are inclined by cutting out the upper and lower portions of the fins 4a of the corrugated panel formed by continuously bending a thin copper plate with an inclination
2 and make this corrugated panel 4 a fin 4a as shown in FIG.
Weld the upper surface and the lower surface of the tank to the side plate 2 of the tank so that the welding angle α is in the range of 95 ° to 135 °,
This is a corrugated tank as shown in FIG.
なお上記実施例では波形タンク４のフイン４ａの上面及
び下面の全面を傾斜させているが、この傾斜は溶接角度
αが９５°〜１３５°となればよく上面及び下面の全面
を傾斜させたものに限るものではない。Although the upper surface and the lower surface of the fin 4a of the corrugated tank 4 are inclined in the above embodiment, the inclination is such that the welding angle α is 95 ° to 135 ° and the entire upper surface and the lower surface are inclined. It is not limited to.
Ｈ．考案の効果 （１）本考案によれば波形タンクの最大の弱点であるタ
ンクの側板と波形パネルの溶接部に生ずる応力集中が緩
和しタンクの強度が上るので、波形タンクの信頼性が向
上する。H. Advantages of the Invention (1) According to the present invention, stress concentration generated in the welded portion of the side plate of the corrugated tank and the corrugated panel, which is the greatest weak point of the corrugated tank, is relaxed and the strength of the tank is increased, so that the reliability of the corrugated tank is improved. .
（２）油入変圧器における波形タンクの適用範囲は最大
１５００ＫＶＡ程度でるあが、従来の構成で適用範囲を
拡大するためには、吊り上げなどの強度上波形パネルの
板厚を厚くする必要があるが、それでは波形パネルの薄
いものに比して必要な膨張量を得るときの圧力がなり、
又タンクの側板と波形パネルの溶接部の応力も高くなり
好ましくないが、本考案によれば同じ板厚でタンク強度
が増加するので、板厚を増すことなく適用容量範囲を拡
大することができる。(2) The application range of the corrugated tank in the oil-filled transformer is about 1500 KVA at maximum, but in order to expand the application range with the conventional configuration, it is necessary to increase the plate thickness of the corrugated panel due to strength such as lifting. But then, the pressure when obtaining the necessary expansion amount compared to the thin corrugated panel,
Further, the stress of the welded portion between the side plate of the tank and the corrugated panel becomes high, which is not preferable, but according to the present invention, the tank strength increases with the same plate thickness, so that the range of applicable capacity can be expanded without increasing the plate thickness. .
（３）本考案によればタンクが膨張に対して強くなるの
で、膨張量を確保する圧力に対する強度を基準とするこ
となく、あくまでも放熱器としての温度のみを基準とし
て設計できるから、温度的に必要な寸法以上に波形パネ
ルを大きくする必要がない。(3) According to the present invention, since the tank becomes strong against expansion, it is possible to design only based on the temperature of the radiator as a reference without using the strength against the pressure to secure the expansion amount as a reference. There is no need to make the corrugated panel larger than necessary.
