摘要
针对目前高压电机频繁烧毁及其保护存在的问题,设计出以电流幅值、负序及零序电流为判据的微机综保护系统,基本实现了数字化处理,能够覆盖高压电机可能出现的所有故障,并具有智能化故障诊断功能.
<Abstrcat>An intelligent unified protective system of HV asynchronous motors which works by detecting current amplitude,negative and zero?sequence current is described.Digitization processing is basically implemented.It covers the propably electric faults of mining HV motors.Intelligent fault diagnostic function is also equipped.
