摘要(Abstract)：

为研究降雨环境对弓网电弧辐射电场噪声特性的影响,利用弓网电弧电磁噪声实验系统,在电波暗室中开展降雨环境下的弓网电弧电场噪声实验.统计分析降雨环境下弓网电弧电场噪声的时域特性,获得了弓网电弧电场噪声时域波形的峰值、上升时间、振荡周期及持续时间等特性参数随降雨量、接触压力及滑动速度的变化规律,研究降雨环境下的弓网电弧电气特性及其与电场噪声特性规律之间的关系.结果表明:弓网电弧电场噪声强度随降雨量的增加而增强,在降雨环境下电场噪声强度随滑动速度的增加而减弱;与正常环境相比,降雨环境下的电场噪声波形的幅值更大、衰减更快.降雨会使电弧的燃弧时间缩短,零休时间增加,进而导致燃弧尖峰增大.
