摘　　要：利用超高频微带贴片天线传感器和超高频滤波放大器,实现了局部放电信号的采集、提取、调理和传输。采用LabVIEW图形化语言的虚拟仪器技术实现了对气体绝缘组合电器(GIS)设备局部放电信号的定时循环检测、信号处理、数据分析、缺陷类型模式识别、监测数据查询和绝缘状况初步评估等功能。该系统已在重庆市某220 kV级GIS变电站成功运行,试验运行结果表明,采用虚拟仪器技术的GIS局部放电超高频在线检测系统能实现GIS局部放电超高频检测。The PD signals were acquired, processed and transmited by the UHF antenna and UHF filter-amplifiers. The software system could realize the functions of time-cycle examining, PD signals processing, history data analyzing, type-pattern recognition, trend querying and primary evaluation of insulation condition with the technique of virtual instruments. This system had been running in a 220 kV GIS Substation of Chongqing. The field results show that the UHF PD on-line monitoring system of GIS based virtual instruments could detect the UHF GIS PD signals effectively and efficiently.
