摘要
本文论述的局部放电超高频扫描式在线监测系统,采用了嵌入式处理器及大规模可编程逻辑器件,通过比较扫描的方式,获取局部放电的放电特征量,不需A/D采集卡,信号就地数字化,适宜于分布式的监测系统,且系统扩展性好。该系统能实时在线监测,且使用部件少、设备体积小,便于安装。
This essay introduces the UHF scanning online monitoring system for partial discharge in which the embedded processor and the large-scale PLD are applied.By means of comparative scanning,the system acquires the characteristic quantity of partial discharge without the use of the acquisition card.Signals collected can realize in-situ digitization.Therefore,the system,with excellent expansibility,can also realize the function of distributed monitoring as well as real-time online monitoring.Finally,the system needs only a few components and the equipment is small in size as well as easy to install.
