The production quality and efficiency of the transformer iron core can be improved, and the transformer performance is improved.

Description

technical field [0001] The invention relates to the technical field of transformer manufacturing, in particular to a production process for manufacturing transformer cores using 3D printing technology. [0002] technical background [0003] Transformer is one of the important equipment in power system. The transformer core is the main component of the transformer. The iron core plays a very important role in the process of energy conversion and electromagnetic conversion of the transformer. It is also the installation skeleton of the transformer. [0004] The manufacturing process of the transformer core is very complicated, and the quality requirements are relatively high. The current defects in the manufacturing of transformer cores are: 1) Seams: The assembly form of transformer cores results in a large number of seams, and the no-load current and no-load loss will increase due to the increase in the number of seams between the cores. 2) Damage: Scratching during proce...

AI Technical Summary

Problems solved by technology

At present, the defects in the manufacturing of transformer cores are: 1) Seams: the assembly form of transformer cores results in a large number of seams, and the no-load current and no-load loss will increase due to the increase in the number of seams between the cores

2) Damage: Scratching during processing will damage the interlayer insulation, and insulation damage will lead to increased eddy current loss

7) Corrosion: The surface of the transformer core is prone to rust during the production and import process, and the corrosion seriously affects the insulation performance of the transformer

8) Complicated assembly: In the process of assembling the transformer core, in order to ensure the geometric size and shape, the assembly process is very complicated and the labor hours are long

9) The process is backward, the production period is long, many operators are required, the labor productivity is low, and the manufacturing cost of the iron core is increased.
