Abstract

The invention relates to the field of transformers, in particular to a split winding type transformer. two groups of low-voltage windings, two groups of high-voltage windings and two groups of regulating windings are jointly wound around a formed hard paper cylinder respectively, iron yoke insulation is additionally formed between the two groups of regulating windings to serve as a line outgoing channel, so that the structure is simpler, the arrangement is tighter, the sleeving is convenient, the size of the split winding type transformer is effectively reduced, and the electrical strength and mechanical strength are improved; the low-voltage windings adopts a continuous structure, the number of segments of the windings is odd, the line outlet positions of the head and tail ends of the low-voltage windings are positioned close to one side of a first formed hard paper cylinder, the operation is convenient, the insulation distance from the line outlet positions of the low-voltage windings to the high-voltage windings is increased, the split winding type transformer is safer and more reliable, the dimension of the body of the 110kV level split winding transformer can be reduced, the size of the transformer is shortened, the consumption of raw material is saved, and the cost is reduced.

Description

(1) Technical field [0001] The invention relates to the field of transformers, in particular to a split transformer. (2) Background technology [0002] At present, in the 110kV class split transformers in use, the low-voltage windings, high-voltage windings, and voltage-regulating windings are all wound separately and packaged separately, which is inconvenient to package and has poor electrical and mechanical strength; The first and last ends of the wires are on the outer diameter side of the winding, and the size of the 110kV class split transformer body is relatively large, and the cost is relatively high. (3) Contents of the invention [0003] In order to make up for the defects of the prior art, the invention provides a split transformer with high strength, small volume and low cost. [0004] The present invention is achieved through the following technical solutions: [0005] A split transformer, comprising a transformer core, a first low-voltage winding and...
