摘　　要：为研究利用超高频法进行GIS局部放电的故障定位,研制了局部放电故障定位系统,定位系统由示波器完成对超高频信号的数据采集,数据处理与运算在计算机中完成,定位方法采用时间差计算法,利用互相关函数算法计算时间差。通过在GIS模型的不同位置设置放电源,进行定位实验,结果表明定位系统可以有效的检测GIS局部放电信号、实现局部放电故障的定位,系统的软硬件设计方案切实可行。In order to study the location of GIS partial discharge using UHF method , the location system of partial discharge is developed. In the system the data is sampled by oscilloscope and the data processing and computing are completed by computer. The time difference which is calculated by the algorithm of cross correlation is used by the software as the location method. The partial discharge sources are placed in the different position of the GIS model. The result of the location experiment shows that the system can effectively detect the partial discharge signal and complete the fault location. The software and hardware design of the system is feasible.
