摘    要:基于弓网放电机理,提取电弧发生时刻放电特征量—(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0~50 Hz谐波幅值明显增加。

关 键 词:弓网电弧  紫外  经验模态分解

Abstract: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.
Keywords:pantograph-catenary arc  uhraviolet(UV)  empirical mode decomposition(EMD)
