摘　　要：基于弓网放电机理，提取电弧发生时刻放电特征量一（250-10）nm波段的紫外光，作为在线检测目标，研制出了一种非接触式紫外弓网电弧检测系统。利用该检测系统对广州地铁二号线弓网电弧现象，进行现场检测，利用经验模态分解（EMD）方法筛除电弧电流的趋势信号，对处理后的电流信号进行分析，结果表明：电弧的发生导致牵引电流中0-50Hz谐波幅值明显增加。Based on discharge mechanism of the pantograph and catenary, extract the characteristic quantity-- （250 -4-10 ）nm wave band ultraviolet light of arcing discharge occurring, as online testing goals, and develops a kind of non-contact UV detection system for pantograph-catenary arcing. Detect the arc phenomenon for Guangzhou Metro Line 2 by this detection system, screen the tendentious signal of current by the way of empirical mode decomposition method and analyze the processed current signal,results show that the arcing causes the 0 -50 Hz harmonic amplitude in traction current increased significantly.
