Abstract
The invention discloses a large-specification enameled wire for a transformer and relates to the technical field of enameled wire processing. The enameled wire comprises a copper round wire, the outersurface of the copper round wire is fixedly connected with a magnetic particle layer, the outer surface of the magnetic particle layer is fixedly connected with an insulating layer, the outer surfaceof the insulating layer is fixedly connected with a polyesterimide paint layer, and the outer surface of the polyesterimide paint layer is fixedly connected with a heat insulation layer. The invention further discloses a processing method of the large-specification enameled wire for the transformer. The processing method comprises the steps of A, wire harness discharging, B, wire drawing, C, cleaning, D, annealing, E, painting and F, lubricating and winding. According to the invention, the enameled wire can work at high temperature for a long time through the thermal insulation layer; the service life of the enameled wire is prolonged; the product quality is improved; the quality defects of pinholes, bubbles and the like generated in the paint film coating process can be effectively avoided through the polyesterimide paint layer; the product quality is improved; and the thermal shock resistance temperature and the high-temperature overload resistance of the enameled wire can also be improved.
Description
technical field [0001] The invention relates to the related technical field of enameled wire processing, in particular to a large-sized enameled wire for transformers and a processing method. Background technique [0002] Enameled wire is generally used to make electromagnetic windings or coils for various purposes. It is a wire with an insulating layer, so it is also called an electromagnetic wire. It consists of conductors and insulating layers, annealed to soften bare copper wires, painted many times, and finally baked. National standards and users have strict requirements on the quality and performance of various enameled wires, including thermal properties, chemical properties, electrical properties, and mechanical properties. However, the strength of the existing enameled wire is not ideal, and it is easy to scratch and affect the quality. [0003] Therefore, it is necessary to propose a large-scale enameled wire for transformers and a processing method to solve the ...
