transformer winding

Abstract

The invention discloses a transformer winding. The transformer winding comprises an inner core (1), and the inner core (1) comprises a hollow cylindrical mandrel (2), a first flat copper wire (3) wrapped by an insulating layer and a second flat copper wire (4) wrapped by an insulating layer. A plurality of winding sections are sequentially formed in the length direction of the mandrel (2) and both the first flat copper wire (3) and the second flat copper wire (4) are continuously wound on the mandrel (2). On one winding section of every two adjacent 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 other winding section of every two adjacent 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. Heat generated by the transformer winding in the working process is little.

Description

technical field [0001] The present invention relates to a transformer winding, in particular to a transformer winding. Background technique [0002] In the prior art, the production of the transformer winding 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 transformer windings The lengths of the flat copper wires in the inner and outer layers are different, which makes the resistance of the flat copper wires in the inner and outer layers different. In this way, there will be a voltage between the flat copper wires in the inner and outer layers during the process. Poor, resulting in a large amount of heat, which greatly reduces the performance of the transformer winding. Contents of the invention [0003] The purpose of the present invention is to provide a transformer winding, which can make the length of the inner and ...
