摘　　要：近年来,利用电力变压器振动信号分析来诊断变压器的故障已经成为研究的新热点,该方法成为变压器故障诊断常规方法的有力补充。本文介绍了变压器常见的故障及其诊断方法,阐述了变压器振动法故障诊断的基本原理、基本过程,回顾总结了国内外变压器振动法故障诊断技术的发展情况,指出目前在变压器振动故障诊断的研究中存在的问题,并分析了其未来有价值的研究方向。In recent years, the method of fault diagnosis for transformers based on their vibration signals has become anew research focus. This method is a powerful substantial supplement of the traditional method for power transformer’sfault diagnosis. This paper describes the common faults and their diagnostic methods of power transformers, and elaboratesthe basic process and the basic principles of this diagnosis method. Furthermore, this paper reviews the development of thefault diagnosis technology for power transformers and points out the problems and difficulties of fault diagnosis oftransformers. Finally, this paper presents the valuable research concentrations of transformer’s fault diagnosis in the future.
