Research on the method of on-line measurement based on the DBD circuit parameters

准确而简单地测量DBD型负载电气参数一直以来都是研究重点,传统的测量方法是通过重构李萨茹图形读取坐标点进行人工计算,费时费力,效率低下且操作复杂。基于李萨如图形测量原理,设计了DBD型负载电气参数在线测量控制系统。该系统通过采集DBD负载上的关键点数据,重新构建李萨如图形,通过软件计算介质阻挡电容、气隙电容、放电维持电压以及放电功率。该控制系统具有操作简单、安全、效率高、误差小和实时在线测量的优点,并通过实验验证了所提出在线测量系统的正确性。

Accuracy and simpleness measurement of load electrical parameters of DBD type is always study focus.The traditional measuring method uses refactoring Lssajous to read the coordinate point and do manual calculation.It＇s laborious,inefficient and needs complicated operation.Based on the measuring principle of Lssajous graphic,the on-line measurement control system of load electrical parameters is designed.In this control sysem,the key data is collectted,the Lssajous is rebuided.The dielectric barrier capacitance,the air gap capacitance,the discharge voltage and the discharge power are obtained by the software accuracy.The control system has advantages of simple operation,safety,high efficiency,low error and the real-time online measurement.And the correctness of the online measuring system is verified by the experiment.
