Abstract

The invention discloses a co-wound high-voltage and low-voltage coil. The co-wound high-voltage and low-voltage coil comprises an iron core and a high-voltage insulating barrel, wherein the high-voltage insulating barrel is arranged at the outer part of the iron core, a high-voltage coil supporting bar is arranged on an outer surface of the high-voltage insulating barrel, and a high-voltage coil is wound at the outer part of the high-voltage coil supporting bar. The co-wound high-voltage and low-voltage coil is characterized in that the high-voltage coil supporting bar is provided with a protruding end relative to the high-voltage coil, a low-voltage soft paper barrel is arranged at the outer part of the protruding end of the high-voltage coil supporting bar, a low-voltage coil supporting bar is arranged at the outer circumference of the low-voltage soft paper barrel, and a low-voltage coil is wound at the outer part of the low-voltage coil supporting bar. According to the invention, the problems of complex winding process and much tooling equipment of the high-voltage and low-voltage coil in the prior art are solved. The co-wound high-voltage and low-voltage coil has the advantages of simple structure, simple winding process, high production efficiency and low cost.

Description

technical field [0001] The invention discloses a high-voltage and low-voltage co-winding coil of a transformer and a winding method thereof, belonging to the technical field of transformers. Background technique [0002] The current winding method of the high and low coils of the transformer is generally to arrange the stays on the outer sides of the high and low voltage insulating cylinders respectively, and then wind the high voltage coil and the low voltage coil respectively. After winding, the high-voltage coil and the low-voltage coil are set together. The disadvantages of this winding method are as follows: Each coil needs to be installed and disassembled twice, which invisibly increases the cost of man-hours; high and low voltage are wound separately, and the coils need to be packaged together when they are shaped and pressed, and the accuracy of the package is relatively high. High, if the concentricity of the coils is not well supported and the phenomenon of non-co...
