Description

Technical Field

[0001] The utility model relates to the technical field of electrical circuits, in particular to a transformer parallel wire winding transposition mechanism. Background Art

[0002] The existing transformer coil is wound with multiple wires in parallel. The distance between each wire and the core is different, resulting in different lengths. At the same time, the magnetic field induction effect on the wire is also different, which will cause imbalance in wire resistance and inductance. Therefore, measures must be taken to transpose the parallel wires, that is, to change the radial arrangement of the wires so that the lengths of the parallel wires are equal, so that the magnetic induction positions passed by each wire are the same, so that the losses of the parallel wires are similar, and the circulating current between the parallel wires is very small or close to zero; at the same time, the temperature rise of each parallel wire is similar, so that "complete transposition" is achieved. According to conventional winding, the wire lengths are inconsistent, the circulating current is relatively large, and the additional loss of the winding is also relatively large.
