摘要
电力设备的绝缘问题是导致电力设备故障和事故的主要原因之一,通过局部放电监测可以提前判断电力设备绝缘状况。目前已有多种针对局部放电的检测方法,其中光纤珐珀(Fabry-Perot,F-P)超声传感器具有抗电磁干扰能力强、绝缘性好、灵敏度高等优势,在超声检测方面得到了众多研究者的青睐。为此概述了几种常用的局部放电检测方法,介绍了光纤F-P腔的干涉原理以及光纤F-P超声传感器的工作机制,重点总结归纳了基于银膜片、聚合物膜片、石墨烯薄膜和硅膜片非本征光纤F-P超声传感器的性能制备方法,同时详细分析了光纤F-P超声传感器在模拟局部放电源的检测和定位中的优势。最后通过介绍微机电系统(micro-electro-mechanical systems,MEMS)技术在光纤F-P超声传感器中的应用现状,对基于MEMS技术的非本征光纤F-P超声传感器在局放检测中的应用前景进行了总结和展望。
The insulation problem is one of the main causes of power equipment failures and accidents.The insulation status of power equipment can be judged in advance through partial discharge(PD)monitoring.At present,there are a variety of detection methods for PD detection,and the optical fiber Fabry-Perot(F-P)ultrasonic sensor has the advantages of strong anti-electromagnetic interference,good insulation,and high sensitivity.It has been favored by many researchers for ultrasonic detection.We give an outline of several commonly used PD detection methods,introduce the principle of optical fiber F-P cavity interference and the working mechanism of optical fiber F-P ultrasonic sensors,and focus on the performance parameters and fabrication manners of the four extrinsic fiber F-P ultrasonic sensors constructed by the silver diaphragm,polymer diaphragm,graphene diaphragm and silicon diaphragm,respectively.Moreover,we summarize the advantages of fiber F-P ultrasonic sensor for imitative PD detection and location in detail.In the end,we introduce the application of micro-electro-mechanical systems(MEMS)technology in fiber F-P ultrasonic sensors,and present the conclusions and prospects of the extrinsic fiber F-P ultrasonic sensors based on MEMS technology in PD application prospect.
