摘要

提出了一种基于正负序列信号的提升机电机短路的故障诊断方法。该方法仅通过电压和电流信号来诊断匝间短路故障(ISCF)的严重程度和轻微的ISCF

不需要考虑电机的旋转角度和定子电阻和电感等模型参数。建立了提升机电机匝间短路故障仿真模型

并对其故障特征进行分析

最后提出了基于正负序列信号的提升机电机故障诊断方法。实验结果表明:所提方法用于诊断提升机电机ISCF严重程度和轻微ISCF是有效的。

Abstract

A fault diagnosis method for hoist motor based on positive and negative sequence signals is proposed.This method only uses voltage and current signals to diagnose the severity of the inter-turn short circuit fault（ISCF） and slight ISCF

regardless of the rotation angle of motor and model parameters such as stator resistance and inductance.The simulation model for hoist motor ISCF is established

and its fault characteristics are analyzed.Finally

a fault diagnosis method for motor based on positive and negative sequence signals is proposed.The experimental results show that the proposed method for diagnosing the ISCF severity of the hoist motor and the slight ISCF is effective.
