摘要
根据高压电动机现有保护存在的问题 ,基于对称分量法检测电动机故障时各序电流分量的大小为保护判据 ,简单分析了电机的故障特征 ,应用单片机实现其综合保护。
Based on the existing problems in the protections for HV motor and by taking the magnitude of current component on each sequence during motor fault tested by means of synchronous component method as the protection's criteria, the fault characteristic of motor is analyzed in this paper. And its integrated protection is implemented by a single-chip processor.
