摘要
根据GIS局部放电脉冲所激发的电磁波传播特性的宽频带特征,设计出一种新型超宽带天线局部放电检测系统,利用该系统检测252 kV GIS母线段中不同气压下固定微粒局部放电模型的实验结果表明外部传感器超高频局部放电检测系统可在线检测GIS局部放电。
Based on mechanism of partial discharge in GIS and frequency domain features of PD, a new - type broad band antenna (sensor) of PD detection is designed and external sensors for ultra high frequency partial discharge detection system of GIS is set up in this paper. The partial discharge of fixed particle under different SF6 pressure in 252 kV GIS bus bar is detected. The results indicate that this system can realize PD on line detection of GIS.
