变频器故障诊断技术研究与分析

Advances and prospect of fault diagnosis technology in frequency converter

针对变频器故障诊断技术的重要性,在分析了国内外对这一问题研究现状的基础上,展望了这一领域中有待进一步研究的若干问题和发展趋势。指出了融合多种方法研究变频器的故障诊断技术,建立其预警系统,将有助于变频器故障诊断技术的理论研究。

Frequency Converters have been widely applied in industry and agriculture. The fault diagnosis of frequency converter becomes more and more important. First, the fault types of frequency converter are introduced. Then, the study state at home and abroad is presented. Finally, further problems to be studied in this field and the development trends are pointed out. And this paper emphasizes that it has great value in theory and practice to study the fault diagnosis of frequency converter combining many different methods and set up its prewarning system.
