Description

Technical Field

[0001] The present invention relates to the technical field of transformer winding processing, and specifically provides a transformer winding processing device and a processing method therefor. Background Art

[0002] The transformer winding refers to the circuit part of the transformer, which is wound by copper wires or aluminum wires with high electrical conductivity and is applied to the power system. The winding has sufficient insulation strength, mechanical strength and heat resistance. Windings are usually divided into two types: layer type and pancake type. For example, the foil winding is a type of layer winding.

[0003] The foil winding is wound with copper foil or aluminum foil. Each winding layer is one turn. Each layer of copper foil is separated by insulating paper. The insulating paper can be superimposed on the copper foil and wound together. The area of the insulating paper is larger than that of the copper foil, and the copper foil is centered in the middle of the insulating paper. During the co-winding process, insulating paper strips with the same thickness as the copper foil are additionally wound on the part of the insulating paper that extends beyond the copper foil, thereby adding insulating ends on both sides of the copper foil.

[0004] Although the above can wind the foil winding, inevitably, in the actual use process, there are still deficiencies. Among them, the device lacks an automatic insulating end laying mechanism, resulting in the problem that the winding of the insulating ends is time-consuming and laborious. Therefore, a transformer winding processing device and a processing method are proposed to solve the existing problems. Summary of the Invention
