Embodiment Construction

[0020] The utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] A method for preparing a corona-resistant enamelled flat wire covered with glass filaments. Two kinds of corona-resistant enameled wire varnishes are directly used in the enamelling process, and the enameled wire is treated as a corona-resistant enameled wire, and then wrapped with glass filaments, dipped in paint, and baked. A corona-resistant enamelled flat wire covered with glass fiber with a five-layer insulation structure is obtained. The method adopts a three-layer insulation structure, the primer is polyester corona-resistant paint, the middle paint is polyesterimide corona-resistant paint, and the top coat is polyamide-imide paint. The corona resistance performance of the corona-resistant enamelled flat wire produced by this structure is better than that of the corona-resistant polyimide film wrapped enamelled flat wire. Due to the introducti...

Abstract

The invention discloses a preparation method and a product of a glass fiber covered corona-resistant enameled rectangular wire. The method is characterized by comprising the following steps of: treating an enameled wire into a corona-resistant enameled wire by using two types of corona-resistant enameled wire paint; and lapping glass fiber, dip coating and baking so as to obtain a glass fiber covered corona-resistant enameled rectangular wire with a three-layer insulating structure. In the method, the three-layer insulating layer is adopted, polyester corona-resistant paint serves as priming paint, polyester-imide corona-resistant paint serves as intermediate paint and polyamide imide paint serves as finish paint.

Description

technical field [0001] The utility model relates to a preparation method and product of motor components, in particular to a preparation method and product of a corona-resistant enamelled flat wire covered with glass silk, belonging to the field of electric wires and cables. Background technique [0002] AC variable frequency motors have the advantages of energy saving, good speed regulation performance, stepless speed regulation and fast braking, etc., which make AC variable frequency motors widely used in household appliances, elevators, railways, metallurgy and other industries. However, due to the use of variable frequency power supply, the problem of premature destruction of the insulation system of the variable frequency motor has also been caused. Scholars at home and abroad have conducted extensive and in-depth research on the phenomenon of premature failure of the insulation of variable frequency motors, showing that the pulse square wave output by the pulse width m...
