Embodiment Construction

[0024] The present invention will be further elaborated below in conjunction with the accompanying drawings of the description.

[0025] A kind of K transposition helical coil winding method of the present invention comprises the following steps:

[0026] Before the coil is wound, the quantity of the tooling block 1 is determined according to the number of the oil passage pads in the circumferential direction of the coil in the drawing; during the winding process, the oil passage block 3 is placed while the wire is being wound, and the tooling block 1 is set on the coil On the top of the oil passage cushion block 3 in the circumferential direction, it is placed in one-to-one correspondence with the oil passage cushion block 3; the tightening belt 2 is used to tighten the tool press block 1 on the periphery of the tool press block 1.

[0027] like Figure 2A As shown, in this embodiment, the coil is wound by a vertical winding machine, and the number of tooling pressing blocks...

Abstract

The invention relates to a K-transposition spiral coil winding method, comprising the following steps: before the coil is wound, the number of tooling briquetting blocks is determined according to the number of oil passage pads in the circumferential direction of the coil in the drawing; The guide wire is placed on one side of the oil passage pad, and the tooling pressure block is set above the oil passage pad in the circumferential direction of the coil, and placed in one-to-one correspondence with the oil passage pad; the tooling pressure block is tightened around the tooling pressure block with a tightening belt . The method of the invention makes special auxiliary tooling during the coil winding process to ensure the production of the product. The tightness, so as to better ensure the manufacturing quality of the transformer coil.

Description

technical field [0001] The invention relates to the manufacturing field of a transformer, in particular to a "K transposition" spiral coil winding method. Background technique [0002] At present, the transformer industry is developing rapidly, and users have higher and higher requirements for the performance of transformer products. Therefore, it is necessary to continuously develop innovative high-voltage, high-current large-capacity transformers, and these transformers will be used in national key projects. In the transformer manufacturing industry, most transformer coils adopt a spiral structure. In the past two years, a spiral coil structure using a single wire with a very narrow width, at least 20 windings, and a K-type transposition has been developed. "K transposition" is to ensure that the lengths of multiple parallel-wound wires are close to the same length during the coil winding process, and the outermost wire of the multiple parallel-wound wires is bent to the...
