摘要
详细分析了高压异步电动机的故障特征及现有保护的不足 ,讨论了基于检测正、负、零序电流分量的高压异步电动机综合保护的原理和方法 ,该方法能够覆盖高压异步电动机的常见故障 ,并具有智能化的故障诊断功能。
A detailed analysi s was made on failure characteristics and existent protection limitations of the high voltage asynchronous motor,and a discussion was made on the principle and method of comprehensive protection of the high voltage asynchronous motor based on measure of current component of positive sequence,negative sequence and zero sequence.The method can solve common failures of the motor and has failure diagn osis function of intellectualization.
