Description
【発明の詳細な説明】 本発明は、変圧器外箱の改良に関するものである。[Detailed description of the invention] The present invention relates to an improvement of a transformer outer box.
一般に変圧器外箱は、外箱の最底部から最高部まで外箱
の高さ一杯に複数本の縦補強ビームを溶接で固定しかつ
補強している。In general, a transformer outer box is reinforced by welding a plurality of vertical reinforcing beams that span the entire height of the outer box from the bottom to the highest point.

により固定するようにしたものである。The vertical reinforcing beam was fixed to the outer box by welding with the same fixing strength for the entire length of the longitudinal reinforcing beam, regardless of the strength (stress distribution) required for the transformer outer box. There was a drawback that the length was long and deformation due to welding was large. The present invention eliminates the above-mentioned drawbacks, reduces the melting length of the vertical reinforcing beam that reinforces the outer case to the necessary limit, and reduces deformation based on welding and reduces the number of work steps. The purpose of this is to provide an outer box for a vessel, and the fixation between the outer box and the longitudinal reinforcing beam is determined by welding the upper and lower ends of the outer box, depending on the stress distribution acting on the outer box, and reducing the moment strength. The center side from the displacement point is fixed with adhesive.

An external force P is applied to the outer box 1 as shown in FIG. 2 in the step of dealing with moisture absorption during the manufacturing process, and as a result, the bending moment distribution diagram shown in FIG. 3 is drawn both experimentally and computationally.

,,The stress is 0 at each displacement point Q,,Q2 of M2 and M3, and the moment distribution length h2 of the strength M2 is
The stress in the part is small, and the tensile force acts in the same direction. Therefore, in the transformer outer box of this embodiment, the vertical reinforcing beam 2 is fixed to the outer box 1 using an effective adhesive such as Araldide AV (trade name) for this h2 portion, and the thermal strain caused by welding is avoided. This prevents deformation, etc. Then, the height of the outer box 1 (total length of the vertical reinforcing beam 2) is h,,
Since the portion h2 requires great strength, it is fixed by welding as in the conventional structure. In addition, since the main load when lifting the outer box 1 is received by the base 5,
Even if a part of the fixing portion of the vertical reinforcing beam 2 to the outer box 1 is fixed with an adhesive, it is sufficient in terms of strength. In this way, the vertical reinforcing beam 2 is fixed to the outer box 1 from the central part of h2 to the displacement point Q, , Q2 using adhesive, and by welding from the h2 part to the displacement point Q, , By appropriately fixing beyond Q2 as necessary, it is possible to obtain an outer box structure that is reasonably reinforced by welding and adhesive. As mentioned above, in the transformer outer case of this example, parts that do not require high strength are fixed with adhesive according to the stress distribution acting on the outer case, so welding is done over the entire length of the vertical reinforcing beam as in the conventional case. It is possible to shorten the manufacturing process and reduce the number of man-hours compared to the case where the outer case 1 is deformed due to thermal stress caused by welding, especially in the H2 part where deformation is likely to occur. No shaping work is required and the number of man-hours can be reduced.

きる効果を有するものである。As described above, the transformer outer casing of the present invention has the effect of reducing the welding length of the reinforcing beam that reinforces the outer casing to the necessary limit, thereby reducing deformation caused by welding and reducing the number of work steps. It is something that you have.
