摘 要:感应电机在工业中扮演重要角色,它的可靠安全运行至关重要。由于感应电机结构、湿度以及温度的影响,感应电机的故障时有发生。感应电机在线故障诊断的基本步骤包括提取故障信号、提取故障特征信息以及故障状态识别。首先在线提取故障信号,然后通过信号处理技术提取故障特征信息,最后通过算法确定故障类别。文章对当前的感应电机在线故障诊断的研究现状和发展趋势进行探讨。 关键词:感应电机;故障诊断
Abstract: Induction motor play an important role in industry,its reliably and safety operation is very important.Due to the induction motor structure,humidity and temperature,induction motor faults occur frequently.Induction motor on-line fault diagnosis of basic steps include extract fault signal,extract fault feature information and fault state identification.Extracting fault signal online firstly,and extracting the fault feature information by signal processing technology,then determinineing the fault category by algorithm.Based on the current on-line fault diagnosis of induction motor,the research present situation and development trend were discussed in the paper. Key Words: Induction motor;Fault diagnosis
