Description

Winding structure of 10KV medium-sized transformer

Technical Field

The utility model relates to an oil-immersed transformer field, especially a winding structure of 10KV medium-sized transformer.

Background

At present, in a product of the medium-sized transformer above 5000KVA, an oil-immersed transformer winding adopts a continuous structure and a positive and negative cake structure, so that the winding method is adopted as a conventional winding method, the winding of the conventional method is complex, a temporary winding coil is needed in the winding process, the winding is performed from inside to outside, when the winding is performed to the outermost layer, an outermost coil of wire passes through, a transition tool is moved to the innermost side, and then one layer of reverse operation is performed, so that the winding method is complex. The starting head is used as the tail head, the position is changed, and the operation is inconvenient. Each cake of coil is wound from inside to outside, one turn is superposed with one turn, the wire is easy to run, and when the number of cakes is odd, the head and the tail of the cake need to be exchanged, so that the coil is time-consuming and difficult to operate.

At present, the production efficiency of large-scale production of electric power products must be improved, the winding is convenient, simple and practical, and the medium-sized transformer winding adopts a continuous structure.

Disclosure of Invention

To the problem that exists among the prior art, the utility model provides an improve production efficiency, the coiling is convenient simple and practical, the winding structure of the 10KV medium-sized transformer of adaptable large-scale production.

The purpose of the utility model is realized through the following technical scheme.

A winding structure of a 10KV medium-sized transformer comprises a bakelite cylinder, wherein end insulators are arranged at two ends of the bakelite cylinder, a coil is wound on the bakelite cylinder, each turn of the coil is wound on the bakelite cylinder in parallel, and the coil is positioned between the end insulators at the two ends of the bakelite cylinder.

The thickness of the wire insulation of the coil is 0.2-0.35 mm.

And an air gap stay is arranged on the bakelite cylinder.

And a tensioning cloth plate is arranged between the coil and the bakelite cylinder.

Compared with the prior art, the utility model has the advantages of: the utility model discloses a winding structure, according to the coiling of small capacity product drum formula like this saved a large amount of time, reduced intensity of labour, simultaneously as long as the thickness of the line insulation of control coil in the coiling, just can guarantee its electrical property and mechanical properties.
