摘要

提出了一种用于电力变压器套管声发射检测的光纤干涉法，并对仿真声发射信号进行了测试。实验结果表明，该系统能够有效地检测衬套复制品内部的声发射。系统灵敏度优于用于电力变压器局部放电声发射检测的传统压电声传感器。

Fiber optic interferometric method for acoustic emissions detection on power transformer's bushing

Fiber optic interferometric method for acoustic emission (AE) detection in power transformer's bushing is developed and tested in emulated AE signals. It was shown that the proposed system can detect AE from inside a bushing replica. It was also shown that system sensibility is better than traditional piezoelectric acoustic sensors usually used for AE detection originated from partial discharge (PD) on power transformers.
