| 摘 要： | 放电区域电场的定量测量是研究长空气间隙放电机理的重要手段,也是近年国内外研究的热点。简要介绍了自主研制的光电集成电场测量系统,并将其应用于棒–板间隙在正极性雷电冲击电压作用下流注放电区域电场的测量。首先测量未发生放电时棒–板间隙轴线上的几何电场,并与计算结果进行对比;其次,测量流注产生后放电区域内、外的电场强度,并结合高速摄像机拍摄到的流注放电图片对测量结果进行分析。测量结果为流注通道与空间电荷的物理模型建立提供了依据。

| Abstract: | The quantitative measurement of electric field is helpful for researching mechanism of long air gap discharge,and it is also one of hot topics in recent years.An electric field measurement system based on the integrated electro-optical technology was proposed.Firstly,the electric fields on the axis of 1 m rod-plane energized by positive lightning impulse voltage without any streamer were measured.The measurement results were compared with calculation results to verify the accuracy of the measurement system.... |
