摘要
介绍了近年来声发射 (acoustic emission, AE) 技术在变压器局部放电测量方面的发展及应用情况, 详细说明了用声发射技术检测变压器局部放电的原理, 对检测系统结构、定位测量方法及局部放电声发射信号的模式识别进行了概述, 探讨了该方法的优缺点和今后的发展方向。
The application of acoustic emission technique to detection of partial discharges in power transformers is introduced in this paper.The theory of the said method, the system structure,the locating means and the pattern recognition methods are described. Additionally,relative merits and development direction of this method are discussed.
