Problems solved by technology

[0002] In a transformer, a continuous coil with multiple wires wound in parallel must be transposed for each cake of wires. Generally, multiple wires are transposed and arranged together (such as figure 2 As shown), due to the different positions of the leakage magnetic field of multiple wires, the induced potential of each wire is different to generate a potential difference, and a circulating current will be generated between multiple wires, which will increase the loss and generate overpotential

Abstract

The invention relates to a continuous coil multi-wire parallel winding wire transposition structure, which comprises a continuous coil formed by a plurality of line segments. Each line segment is formed through parallel winding of multiple wires. The plurality of line segments are positively and negatively wound alternately; a plurality of wire transposition zones are arranged between two adjacent line segments; and the plurality of wire transposition zones between the two adjacent line segments are uniformly distributed along the circumference of the coil. According to the continuous coil multi-wire parallel winding wire transposition structure, wire transposition uniform distribution makes electric potential difference between the parallel wound wires zero, and no circulating current loss is caused; and amplitude size of the coil can be reduced, and manufacture cost of a transformer is reduced.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a transposition structure with multiple continuous coils and wires wound around them. Background technique [0002] In a transformer, a continuous coil with multiple wires wound in parallel must be transposed for each cake of wires. Generally, multiple wires are transposed and arranged together (such as figure 2 As shown), due to the different positions of multiple wires in the leakage magnetic field, the induced potential of each wire is different to generate a potential difference, and a circulating current will be generated between multiple wires, which will increase the loss and generate overpotential. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a continuous coil with multiple parallel-wound wires transposition structure, the transposition of the wires is evenly distributed, so that the potential dif...
