摘要
漆包线作为电机三大主绝缘材料之一，直接影响电机输出性能与使用寿命。为探究不同涂层高压扁线的性能表现，本文从绝缘老化机理分析入手，建立主绝缘铜线的热 - 湿 - 油 - 电多因子老化模型，经高湿、自动变速箱油、高低温等多因子老化处理后，验证不同涂层扁线的老化特性。
Abstract
Enameled wire, as one of the three main insulating materials of motors, directly affects the output performance and service life of motors. To explore the performance of high-voltage flat wires with different coatings, this paper starts with the analysis of the insulation aging mechanism and establishes a multi-factor aging model of the main insulation copper wire-heat, humidity, oil and electricity. After multi-factor aging treatments such as high humidity, automatic transmission fluid, and high and low temperatures, the aging characteristics of flat wires with different coatings are verified.
