摘　　要：为了分析无人机巡线或特殊机器人作业时与线路之间发生放电产生的电磁干扰,研究高压导线与悬浮导体之间的放电规律尤为重要。采用高速摄像机设备进行放电实验的拍摄,利用MATLAB进行图片的灰度值筛选,转化为放电间隔时间后分析数据。分别进行了导线加载不同临界放电电压倍数、改变临界放电电压值、加载风速的放电拍摄实验。得到结果为:放电频率与临界放电电压值无关,随着导线上电压与临界放电电压值比值的增加而相应增大,加载风速会降低放电频率。In order to analyze electromagnetic interference produced by discharge between unmacial robots and transmission lines, it is important to study discharge rules between high-voltage tors. Therefore, the high speed camera was used for shooting and MATLABwas used for grey value filtering for images so as to get data of discharge intervals for analyzing. Discharge shooting experiments on the conductor loaded with different critical discharge voltage multiples, changing critical discharge voltage values and loaded with wind performed. Results indicate discharge frequency is irrelevant to critical discharge voltage value which may augment with in-crease of ratio of conductor voltage to critical discharge voltage value. Besides, wind speed may decrecy.
