GIS局部放电重症云监护技术及其应用分析

GIS Partial Discharge Intensive Cloud Monitoring Technology and Its Application Analysis

针对GIS设备局部放电问题,文章详细讲述了GIS局部放电重症云监护技术在GIS重症监护系统中的应用,监测GIS的运行情况.在重症监护段GIS设备上安装特高频局部放电传感器,特高频传感器所检测到的局部放电信号经高频同轴电缆传输至局部放电采集前端装置,进行模拟滤波、数字滤波、信号放大、局部放电图谱化、局部放电系统自诊断等处理,并将处理后的数字化局部放电信号通过4G无线网络的方式,上传至阿里云端数据库.监测系统软件获取阿里云端数据库中的局部放电数据,并将其可视化呈现,通过PC/移动终端可实时远程异地查看显示局部放电的最终监测结果.

In view of the problem of partial discharge in GIS equipment,this paper describes the application of GIS Partial Discharge cloud intensive care technology in GIS critical care system,and monitors the operation of GIS.The UHF PD sensor is installed on the GIS equipment of the intensive care section.The PD signal detected by the UHF sensor is transmitted to the front-end device of PD acquisition through the high-frequency coaxial cable,and processed by analog fi ltering,digital fi ltering,signal amplifi cation,PD mapping,PD system self diagnosis,etc.,and the processed digital PD signal is passed through 4 G wireless network,upload to Alibaba cloud database.The monitoring system software obtains the partial discharge data in the Alibaba cloud database and visualizes it.Through the PC/mobile terminal,the fi nal monitoring results of partial discharge can be viewed and displayed remotely in real time.
