A winding and binding process of transformer spiral coil

Abstract

The present invention relates to the field of transformer production and manufacturing, in particular to a winding and binding process of a transformer spiral coil, the process is as follows: a. Bending the leads of the coil wires into leads; b. Passing the leads of each lead through the fixing belt and the shrinking belt The rope is fixed on the head of the coil winding mold shaft of the coil shaft; c, the wire body part of the coil wire is wound on the coil inner insulating cylinder of the coil shaft; d, after the winding is completed, the The coil wires are grouped and bound, wherein the connection end of the wire body in each group of coil wires and the wire outlet is bound by shrinkage band A, and the wire body part in each group of coil wires is bound by shrinkage band B, and any adjacent two groups On the adjacent side of the coil wires, one or more coil wires are bound by shrinkage tapes that are adjacent and belong to different coil wire groups; The invention can ensure that the heads of the multi-helical coils are bound firmly.

Description

technical field [0001] The invention relates to the field of transformer manufacturing, in particular to a winding and binding process of a transformer spiral coil. Background technique [0002] In the prior art, the low-voltage and voltage-regulating spiral coils of AC transformers commonly have structures such as 4 helixes and 6 helixes, and the maximum will not exceed 16 helixes. However, with the development of transformer technology, the helical structure of transformer coils has broken through. The upper limit of 16 helix, for example, some products exported to the United States, the voltage regulating coil even reaches 27 helix, and in the process of winding the transformer coil of 27 helix, there are also many new problems that have not been encountered before, such as 27 helix After the helical coil structure is wound, it is difficult to tie the wire at the end because of the large gauge of the coil wire (the wire gauge is 23 self-adhesive transposed wires), the sma...

However, with the development of transformer technology, the helical structure of transformer coils has broken through. The upper limit of 16 helix, for example, some products exported to the United States, the voltage regulating coil even reaches 27 helix, and in the process of winding the transformer coil of 27 helix, there are also many new problems that have not been encountered before, such as 27 helix After the spiral coil structure is wound, due to the large wire gauge of the coil wire (the wire gauge is 23 self-adhesive transposed wires), the small diameter of the coil, and the large number of wires, it is difficult to tie the wires tightly.
