Problems solved by technology

However, when 6 wires are wound in parallel, the transposition according to the traditional standard transposition method is incomplete transposition, and the wound winding will generate circulating current, which will increase the load loss of the transformer and increase the manufacturing cost of the transformer.

Abstract

The invention discloses a method for manufacturing a continuous winding transformer coil with 6 wires wound in parallel, which can realize the complete transposition of the 6 wires in the parallel winding of 6 wires, because the number of times each wire is wound in the same wire position The same, so the total length of the 6 wires is equal, making the resistance of the wires equal. At the same time, the leakage magnetic flux passing through the six wires is equal, so the induced magnetic leakage electromotive force of each wire is equal. Furthermore, the terminal voltages of the six wires are equalized, the circulation current between the wires is avoided, and the load loss of the transformer is reduced.

Description

technical field [0001] The invention relates to the technical field of transformer manufacturing, in particular to a method for manufacturing a continuous winding transformer coil with six wires wound in parallel. Background technique [0002] In the design of large capacity oil-immersed transformer winding structure, continuous winding is the most commonly used winding form. As we all know, the transposition of a continuous winding with one wire or two wires wound in parallel according to the traditional standard transposition method is a complete transposition without circulating current, which is the basic structural form of the continuous winding. However, when 6 wires are wound in parallel, the transposition according to the traditional standard transposition method is incomplete transposition, and the wound winding will generate circulating current, which will increase the load loss of the transformer and increase the manufacturing cost of the transformer. [0003] Th...
