摘　　要：针对GIS耐压试验击穿故障精确定位比较困难的问题;文中在分析GIS耐压击穿时特征信号特性的基础上,结合信号采集、无线传输、智能分析技术,设计一套GIS耐压击穿故障无线定位系统。该系统通过无线自组网的形式,将击穿时刻的特征信号以无线的方式上传至系统数据服务器进行数据分析,并计算击穿故障点精确的位置;同时系统具有较强的抗干扰性、稳定的无线通信等优点。经现场应用,能够准确定位出GIS耐压击穿的故障点。Aiming at the problem that it is difficult to accurately locate the breakdown fault in GIS withstand voltage test,this paper designs a set of a wireless locating system of breakdown fault based on the analysis of characteristic signal characteristics of GIS withstand voltage breakdown,combined with signal acquisition,wireless transmission and intelligent analysis technology.The system uses the wireless ad hoc network to upload the characteristic signal of the breakdown time to the system data server for data analysis in a wireless manner,and calculates the exact location of the breakdown fault point.At the same time,the system has the advantages of strong anti-interference and stable wireless communication.Through field application,the fault point of GIS breakdown can be located accurately.
