Manufacturing method of transformer winding

Abstract

The invention discloses a manufacturing method of a transformer winding. The manufacturing method comprises the steps that 1 a hollow cylindrical mandrel (2) is provided and a plurality of continuous winding sections are marked out on the mandrel (2); 2 a first flat copper wire (3) wrapped by an insulating layer and a second flat copper wire (4) wrapped by an insulating layer are continuously wound from the first end of the mandrel (2) towards the second end of the mandrel (2). The continuous winding sections are divided into the odd winding sections and the even winding sections. On the odd winding sections, the first flat copper wire (3) is wound on the mandrel (2) as the inner layer, and the second flat copper wire (4) is wound outside the first flat copper wire (3) as the outer layer. On the even winding sections, the second flat copper wire (4) is wound on the mandrel (2) as the inner layer and the first flat copper wire (3) is wound outside the second flat copper wire (4) as the outer layer. In the working process, heat generated by the transformer winding manufactured through the method is little.

Description

technical field [0001] The invention relates to a transformer winding, in particular to a preparation method of a transformer winding. Background technique [0002] In the prior art, the production of transformer windings is to overlap the double-layer flat copper wires and wind them on the hollow mandrel. Since the winding circumferences of the double-layer flat copper wires are different during the winding process, the inside and outside of the transformer windings The length of the flat copper wires in the outer layer is also different, which makes the resistance of the flat copper wires in the inner and outer layers different, so that in the process, there will be a voltage difference between the flat copper wires in the inner and outer layers, resulting in a large amount of The heat, which in turn greatly reduces the performance of the transformer windings. Contents of the invention [0003] The purpose of the present invention is to provide a transformer winding, wh...
