摘　　要：本文深入分析了异步电动机的故障特征 ,提出了基于检测电动机过流和负序、零序电流分量的保护判据 ,研究了异步电动机微机保护装置故障电流的整定计算方法。依据该判据 ,本文所研制的异步电动机微机保护装置能够保护电动机的各类常见故障。The paper analyses the fault characteristic of asynchronous mo- tor,puts forward the protection criterion which is based on detection of over- current,zero sequence and negative sequence current component,and re- searches the set calculation method of fault current for microcomputer protec- tor of asynchronous motor.According to this criterion,the microcomputer protectorcan protectvarious common faults of the motor,and itachieves satis- fying results through experiments.
