小波包分解在转子断条故障诊断中的应用研究

Application of Wavelet Packet Decomposition in the Fault Diagnosis of Rotor Bar Breaking

本文通过对转子断条故障诊断的原理进行分析,同时描述转子断条发生故障时稳态定子电流中出现的特征分量。并通过实验结果分析得出三层小波包分解的方法能有效区分转子是否断条。

This paper analyzes the theory of the fault diagnosis of rotor bar breaking and describes the characteristic component in the steady stator current when the rotor bar breaking. It finds that the method of three-layer wavelet packet decomposition can effectively distinguish whether the rotor bar is broken or not by the results of the experiments.
