本考案はタンク側板として波形放熱板を用いて
形成された油入変圧器のタンクに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tank of an oil-immersed transformer formed using a corrugated heat sink as a tank side plate.
一般に油入変圧器のタンク１は、第１図に示す

つて隙間を埋めるには、油漏れが生じやすく、ま
た隙間埋めの溶接作業工数が余分にかかる欠点が
あつた。 Generally, a tank 1 of an oil-immersed transformer is constructed by welding a corrugated heat sink 4 to a frame 2 assembled with a frame as shown in FIG. 1 so as to cover each opening 3 of the frame 2. It is formed. However, when covering the opening 3 with such a corrugated heat sink 4,
As shown in FIGS. 2a and 2b, a substantially triangular gap 5 is formed at the joint between the frame 2 and the corrugated heat sink 4. Therefore, in the past, this gap 5 was filled by welding. However, filling the gap by welding has the disadvantage that oil leakage tends to occur and additional welding work is required to fill the gap.
そこで本考案は上記従来の欠点を解決して製作
工数を大幅に軽減できる油入変圧器のタンクを提
供することを目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide a tank for an oil-immersed transformer that solves the above-mentioned conventional drawbacks and can significantly reduce manufacturing man-hours.
以下に本考案の実施例を図面に基づいて説明す
る。 Embodiments of the present invention will be described below based on the drawings.

ような突起はプレスによつて容易に設けることが
できる。 The tank frame 12 of this embodiment is shown in FIG. 3, and the portion B in FIG. 3 is shown in FIG. 4 on an enlarged scale. As shown in both figures, in this embodiment, protrusions 14 are provided on the upper and lower frames of the tank frame 12 to protrude outward from the tank at equal intervals. These protrusions 14 form the openings 13
When joining the corrugated heat sink 4 to the tank frame 12 in order to cover the corrugated heat sink 4 and the tank frame 12,
They are protrudingly provided at positions corresponding to the gaps 5, respectively, so as to fit into the gaps 5 formed between them. Further, these protrusions 14 have a substantially triangular shape so as to fit into the shape of the gap 5. Incidentally, such projections can be easily provided by pressing.
したがつて、本実施例のタンクにおいては、第
４図に示す如く波形放熱板４の隙間５と突起１４
とを嵌合させ、波形放熱板４をタンク枠体１２に
溶接により取付けるだけで、夫々の隙間５を突起
１４によつて塞ぐことができる。 Therefore, in the tank of this embodiment, as shown in FIG.
By simply fitting them together and attaching the corrugated heat sink 4 to the tank frame 12 by welding, the respective gaps 5 can be closed by the protrusions 14.
尚、本実施例においてはプレスによつて外方に
突出する突起を設けた場合について説明したが、
これらに限らず第５図に示すようなタンク枠を打
抜きそれを折曲げて形成した突起１５を突設して
もよい。 In addition, in this example, a case was explained in which a protrusion protruding outward was provided by a press.
However, the present invention is not limited to these, and a protrusion 15 formed by punching out a tank frame and bending the same as shown in FIG. 5 may be provided.
以上、説明したように本考案によれば、波形放

放熱板を取付ける場合だけ溶接すればよいため、
溶接工数を大幅に軽減することができる。また、
指定隙間で突起が設けられていることから、波形
放熱板の取付け位置を定めやすいため、溶接の際
の位置決め作業も容易となる。 As explained above, according to the present invention, by providing the tank frame with a protrusion that fits into the gap formed between the corrugated heat sink and the tank frame, welding is required only when installing the corrugated heat sink. Because all you have to do is
Welding man-hours can be significantly reduced. Also,
Since the protrusions are provided at designated gaps, it is easy to determine the mounting position of the corrugated heat sink, which also facilitates positioning work during welding.
