Description

Technical Field

[0001] The utility model belongs to the technical field of transformer assembly, and in particular relates to an auxiliary structure for fixing an iron core of a UHV transformer. Background Art

[0002] Ultra-high voltage transformers are mainly used for voltage conversion, current conversion, voltage stabilization and other functions. They are currently the most widely used voltage conversion equipment and are often used in industrial plants, supermarkets, residential areas and other places. The iron core in the transformer serves as the intermediate medium for electromagnetic conversion. It will generate heat when affected by current and other factors during operation. If it is not fixed, it will affect the stability of the transformer.

[0003] The existing fixing structure for the transformer core generally uses a steel beam to wrap and fix it. However, since the core is made of multiple silicon steel sheets, the core is usually clamped and fixed by steel beams on both sides after the splicing is completed. Although it can achieve a fixing effect, it is more troublesome to fix it. It needs to manually tighten the bolts and nuts for fixing. Moreover, this fixing method cannot fix the top and bottom of the core, and the core is prone to misalignment, affecting its stable operation. Therefore, it is an urgent problem to invent an auxiliary structure for fixing the core of a UHV transformer with good fixing effect and simple operation. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an auxiliary structure for fixing the iron core of a UHV transformer, which solves the problem that the prior art uses steel beams on both sides for clamping and fixing. Although it can achieve a fixing effect, it is more troublesome to fix, and it is necessary to manually tighten the bolts and nuts for fixing. Moreover, this fixing method cannot fix the top and bottom of the iron core, and it is easy to cause misalignment between the iron cores, affecting the stable operation.
