基于振动法进行GIL击穿性放电定位方法的研究

A Method Study on Locating GIL Breakdown Discharge via Vibraton Signal

研究了GIL发生击穿性放电时对母线外壳表面产生振动信号的特征,以及使用振动信号进行GIL发生击穿性放电定位的方法及机理。对振动传感器的选型、振动信号的数据采集、振动信号的传输通信机制、振动信号处理的关键算法、传输与分析的软硬件设计和上位机设计进行了较为详细的描述。

This paper has conducted a srudy on the vibration signal characleristics on the bus shell surface as GILsuffers a breakdown discharge, and the method and mechanism to position the breakdown discharge on GIL by vibration signal. It also gives a more detailed description on the lectolype of vibrating sensor, data acquisition of vibration signals, transmission communication mechanism of vibration signal and key algorithms for vibration signal processing, design of hardware and software for transmission and analysis and design of host computer.
