变压器局部放电超声波定位原理

The Principle of Acoustic Locating of Partial Discharge in Transformer

本文根据被动声测原理,研究了大型变压器局部放电的超声定位原理,在局部放电声发射原理和变压器内部声场结构的基础上,推导并给出了局部放电超声定位的球面及双曲面定位方法。

This paper presents the investigation results of the acoustic location methods of the partial discharge in power transformer, It is based on passive acoustic emission principle. Mathematical calculating methods of partial discharge locating in power transformer are derived with the emphasis on improving the locating accuracy.
