Embodiment Construction
[0011] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments;
[0012] Such as figure 1 Shown is the traditional transformer tank structure diagram;
[0013] Such as figure 2 As shown, a large oil-immersed transformer tank includes a tank body 5 composed of four side walls: a front side wall 1, a rear side wall 2, a left side wall 3, and a right side wall 4. The cross-sections of the side walls are all set as a continuous U-shaped structure 6. The continuous U-shaped structure 6 is formed by welding a plurality of U-shaped steel plates. In order to improve the heat dissipation performance, each U-shaped structure 6 is arranged such that the U-shaped opening 61 faces the inner cavity 51 of the fuel tank.
[0014] When processing, first select a steel plate of suitable thickness according to the size of the transformer capacity, and continuously bend the steel plate on a hydraulic press with a special bending die t...

The invention discloses an oil tank of a large-size oil immersed type transformer. The oil tank comprises an oil tank body which is composed of four tank walls, and cross sections of the four side walls of the oil tank body are all configured to a continuous U-shaped structure. The oil tank walls are formed by welding continuously bent U-shaped steel plates. According to the oil tank provided by the invention, the strength of the oil tank can be improved, and the oil tank has the characteristics of simple processing way, small welding amount, capability of saving steel material and labor cost and the like; meanwhile, the surface area of the oil tank is increased, the heat radiation efficiency is improved and the use of heat radiation sheets is saved. Compared with the structure of the traditional transformer oil tank, the oil tank disclosed by the invention has the advantages that: the volume is reduced by about 15%, the cost is saved by about 18% and the economic benefit is obvious; meanwhile, the occupied area and the resource wastes are reduced and the shape of the oil tank is more smooth and attractive, so that the oil tank accords with current low-carbon, green and environment-friendly concepts.
Description
Technical field [0001] The invention relates to a large oil-immersed transformer oil tank, especially a power transformer oil tank of 110kv and above, belonging to the technical field of transformers. Background technique [0002] The body of a large transformer is very heavy, and the volume of the fuel tank is very large. A body weighing dozens of tons or even hundreds of tons must be placed on the base, and the weight of the transformer oil and its tank itself and corresponding accessories can sometimes reach hundreds of tons. . In transportation, the fuel tank is the "packing box" of the transformer. High-voltage and large-capacity transformers require vacuum oil injection. During on-site maintenance, it is required to use a closed pressure vessel with a fuel tank to dry the body. Therefore, there are strict requirements on the mechanical strength of the large transformer tank. If the box-lid structure is still adopted, it is difficult to carry out hanging and repairing on s...
