摘　　要：目前国内敞开式常规变电站数量远远多于GIS变电站,很多敞开式变电站都运行了几十年,由于高压设备的绝缘部件会随时间老化等原因,越来越多的敞开式变电站的缺陷或故障将成为事故隐患。对敞开式变电站进行连续的状态监测和定期的设备巡检,从而及早发现设备缺陷并排除,已成为当务之急的任务。为此,文章提出利用4根射频局部放电传感器组成的天线矩阵,对敞开式变电站内所有高压设备进行局部放电监测和定位。At present,there are far more open conventional substations in China than GIS substations,and many open substations have been in operation for decades.As the insulating parts of high-voltage equipment will age over time and other reasons,more and more defects or failures of open-type substations will become hidden accidents.Continuous state monitoring and regular equipment inspections for open substations,so as to find and eliminate equipment defects as early as possible,has become an urgent task.Therefore,the antenna matrix composed of four RF partial discharge sensors was proposed to monitor and locate all high voltage equipment in open substation.
