Embodiment Construction
[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] Please also refer to Figure 1 to Figure 4 Now, a method for manufacturing a transformer continuous coil provided by the present invention will be described. Define n as the number of wires, k as the number of turns of wire winding, and the coil 100 formed after wire winding is a wire cake, including the following steps:
[0029] a. Wind the 2n wires from the first turn to the k-1th turn at the same time; then divide the 2n wires into two groups on average, and define the group located on the outside of the wire cake as the first group of wires 110, located...

The invention provides a manufacturing method and structure of a continuous coil of a transformer and the transformer, and belongs to the technical field of transformers. When a reverse cake is wound,2n wires are wound to the (k-1) th turn at the same time, then the first group of wires are transposed for winding the next coil cake, and the second group of wires are transposed after the kth turnis continuously wound to obtain the reverse cake; the reverse cake is turned over to obtain a wire cake, the second group of wires are located on the innermost side of the wire cake in the radial direction so that the next wire cake can be continuously wound, then the first group of wires and the second group of wires are wound by the second turn to the kth turn at the same time after being woundby one turn to obtain another wire cake, and the radial size of the wire cake is increased by one time according to 0.5 time of parallel wires; the overall dimension of the coil is accurately controlled, meanwhile, the current density can be more accurately controlled, a more appropriate coil dimension can be selected during application, and the weight of a transformer body is prevented from exceeding the standard and resources are prevented from being wasted.
Description
technical field [0001] The invention belongs to the technical field of transformers, and more specifically relates to a manufacturing method and structure of a transformer continuous coil and a transformer. Background technique [0002] At present, in the pie-type continuous coil, the number of turns of each pie is an integer. If the pie is wound with multiple parallel wires, the multiple parallel wires must have an integer multiple of turns on a single pie. When selecting coil specifications in production applications, only the most suitable and similar coil specifications can be selected, and the width dimension of the coil can only be increased by the integer multiple of the parallel wires, so that the outer dimension of the coil cannot be controlled very accurately, and it will cause The weight of the transformer body exceeds the standard and the waste of resources. Contents of the invention [0003] The purpose of the present invention is to provide a transformer con...
