摘要
风机是矿用隔爆变频器的主要散热部件,工作环境恶劣、故障率很高。利用小波包分析算法提取某大型变频器风机的故障特征向量,并构建了典型故障特征表。在MATLAB平台上用VC软件对其定制,开发出了基于小波包的风机故障诊断系统,该系统能够对风机运行状态进行实时检测和故障诊断。
Fan is the main cooling part of inverter,which works in bad condition,and has a high fault rate.In this paper,wavelet packet analysis algorithm is used to extract the characteristics of the cooling fan of inverter and a feature table of typical fault is built.By using VC and MATLAB,a fault diagnosis system of cooling fan is built based on wavelet packet.The system can effectively do real-time state detection and fault diagnosis.
