Problems solved by technology

[0002] At present, the iron core part of the transformer is mostly Figure 11 The structure shown, which employs two groups such as Figure 9 The shown symmetrical E-type silicon steel sheets are stacked and stacked, and then used such as Figure 10 The compensation sheet shown is packaged. The assembly speed of the transformer iron core of this structure is slow. Due to structural problems, the assembly of the coil and the iron core is often not firm, causing the coil to loosen during operation, causing the casing to resonate and generate large noise, and produce The electromagnetic eddy current loss is large

Abstract

The invention relates to an iron core structure of a transformer. The iron core structure comprises a group of first E-shaped sheets and second E-shaped sheets which are alternatively overlapped continuously. An outer cylinder of the first E-shaped sheet is higher than that of the second E-shaped sheet. A middle cylinder of the first E-shaped sheet is lower than that of the second E-shaped sheet. The iron core structure further comprises a compensation sheet arranged at a gap position formed by overlapping of the first E-shaped sheet and the second E-shaped sheet. The first E-shaped sheet, the second E-shaped sheet and the compensation sheet are provided with connecting holes that are connected and fastened mutually. According to the iron core structure of the transformer, the transformer is assembled rapidly and conveniently, so that the working efficiency is greatly improved, the machine enclosure resonance is reduced, the machine noise is lowered, the magnetic circuit is improved, the magnetic saturation is prevented, the electromagnetic eddy current is reduced, the eddy current consumption of the transformer is effectively reduced and the energy is saved.

technical field [0001] The invention relates to an iron core structure of a transformer. Background technique [0002] At present, the iron core part of the transformer is mostly Figure 11 The structure shown, which employs two groups such as Figure 9 The shown symmetrical E-type silicon steel sheets are stacked and stacked, and then used such as Figure 10 The compensation sheet shown is packaged. The assembly speed of the transformer iron core of this structure is slow. Due to structural problems, the assembly of the coil and the iron core is often not firm, causing the coil to loosen during operation, causing the case to resonate and generate large noise, and produce The electromagnetic eddy current loss is large. Contents of the invention [0003] The object of the present invention is to provide an iron core structure of a transformer with quick and convenient assembly, light case resonance and energy saving. [0004] In order to achieve the above object, the tec...
