摘　　要：电力变压器局部放电超声波检测和定位技术的实现在很大程度上依赖于局部放电所产生的超声波信号的分析与处理性能,所以局部放电超声波信号的分析与处理在局部放电超声波检测和定位技术中至关重要。系统阐述了变压器局部放电超声波信号分析与处理的方法,为局部放电超声波检测性能和定位精度的提高提供参考。The realization of techniques of detection and localization of partial discharges in power transformers adopting ultrasonic methods depends on the analysis and processing of ultrasonic wave signals generated by partial discharges to a large extent, so the analysis and processing of ultrasonic signals generated by partial discharges are of vital importance to the ultrasonic detection and location technology. This paper systematically elaborates the methods of analysis and processing of partial dis- charge ultrasonic signals in order to provide some useful reference for the precision improvement of techniques of detection and localization of partial discharges in power transformers adopting ultrasonic methods.
