Embodiment Construction

[0013] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.

[0014] Such as figure 1 , 35KV new shell-type power transformer body structure, which is composed of clamping wood 1, insulation 2, winding 3, fastening device 4, upper frame 5 and 8 to reduce additional loss, iron core backing plate 6 and iron core 7, etc. , wherein the iron core 7 is fixed between the upper frame 5 and the lower frame 8, and the combined insulation 2 winding 3 is installed on the lower frame 3 to facilitate stacking of the iron cores, and then the iron core 7 is clamped by the upper frame 5. The clamping wood is fixed between the insulating winding phases by the fastening device 4, the insulation is a rectangular structure, and the winding is a cake structure.

[0015] The winding 3 performs conversion between electricity and magnetism and between magnetism and elect...

Abstract

The invention discloses a 35KV novel shell type power transformer body structure which is composed of main components of clamping wood, insulators, windings, a fastening device, an upper frame, iron core skids, iron cores, a lower frame and the like. The iron cores are fixed between the upper frame and the lower frame, the insulators and the windings are combined as required by the technical requirement and installed on the lower frame, and the clamping wood is fixed between all phases of insulators and windings. The insulators are of a triangular structure, and the windings are of a cake type structure. The 35KV novel shell type power transformer body structure has the advantages that due to combination of the insulators, the windings, the frames and the iron cores, on the basis of the principle of electricity and magnetism, the problems that a shell type power transformer is high in cost and a performance index can not be met are solved, and the 35KV novel shell type power transformer body structure has the advantages of being low in cost, low in losses, little in short-circuit impedance, safe, reliable and strong in short-circuit-resistant capacity.

Description

technical field [0001] The invention relates to a body structure of a 35KV novel shell-type power transformer, belonging to the technical field of power transformers. Background technique [0002] At present, there are not many manufacturers of shell-type power transformers in China. First, the voltage is high, the capacity is large, the manufacturing process is difficult, and the cycle time is long; second, there is no core technical advantage; on high current transformers. In terms of power alone, shell-type and core-type power transformers have no obvious advantages in terms of performance and cost, so that the inherent advantages of shell-type transformers cannot be fully utilized. Contents of the invention [0003] The purpose of the present invention is to provide a 35KV novel shell-type power transformer body structure, which can solve the problems of high cost and unsatisfactory performance of the shell-type power transformer. [0004] The purpose of the present ...
