Description

Technical Field

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

[0002] Transformer windings refer to the circuitry of a transformer, wound with high-conductivity copper or aluminum wire, and are used in power systems. Windings must possess sufficient insulation strength, mechanical strength, and heat resistance. Windings are typically categorized as either layer or pancake windings. Foil windings, for example, are a type of layer winding.

[0003] Foil winding is made of copper foil or aluminum foil, with each layer being one turn. Each layer of copper foil is separated by insulating paper, which can be superimposed on the copper foil and wound together. The insulating paper is longer than the copper foil, and the copper foil is centered in the middle of the insulating paper. During the joint winding process, an insulating paper strip with the same thickness as the copper foil is wound on the excess part of the insulating paper relative to the copper foil, thereby adding insulating ends on both sides of the copper foil.

[0004] Although the above-mentioned method can be used to wind foil windings, it is inevitable that there are still some shortcomings in actual use. Among them, the device lacks an automatic laying mechanism for the insulation end, which makes the winding of the insulation end more time-consuming and labor-intensive. Therefore, a transformer winding processing device and processing method are proposed to solve the existing problems. Summary of the Invention
