| 摘 要： | 针对目前高压电动机频繁烧毁及其保护中存在的问题，基于对称分量法理论，分析了高压异步电动机的故障特征。提出了以正序、负序及零序电流为判定依据的电动机综合保护方法，基本覆盖了高压电动机可能出现的所有故障类型，并可实现对故障的自动诊断和高压电动机的综合保护。

| Abstract: | A kind of intelligent unified protective system of HV asynchronyous motors which based on the symmetrical component method is mentioned, the fault characterisics of the HV asynchronous motors are analyzed in detail. It works by detecting positive-sequence current amplitude, negative-seguence and zero-seguence current, and primitively covers all perhaps electric faults of HV motors. The automatic diagnosis of most common faults and a unified protection for the HV asynchronous motor can be realized. |
