摘要
针对目前高压电机频繁烧毁及其保护存在的问题，提出了以电流幅值、负序及零序电流为判据的微机型综合保护系统，基本上覆盖了高压电机可能出现的所有故障。
This paper Proposes a kind of intelligent unified protective system of HV asynchronous motors. It works by detecting current amplitude, negative and zero-sequence current, and primitively covers all perhaps electric faults of HV motors.
