弓网燃弧对城市轨道交通弓网系统和列车运行安全造成严重危害。文章通过对弓网燃弧光谱的提取与分析，研制了基于特征紫外光和光子计数技术的弓网燃弧检测系统。检测结果表明：该系统能有效实时检测弓网燃弧状态；燃弧状态与列车速度相关，速度越大，燃弧率和燃弧强度越大。
弓網燃弧對城市軌道交通弓網繫統和列車運行安全造成嚴重危害。文章通過對弓網燃弧光譜的提取與分析，研製瞭基于特徵紫外光和光子計數技術的弓網燃弧檢測繫統。檢測結果錶明：該繫統能有效實時檢測弓網燃弧狀態；燃弧狀態與列車速度相關，速度越大，燃弧率和燃弧彊度越大。

Through extraction and analysis of the spectrum of pantograph and catenary arcing, the paper studies and develops pantograph and catenary arcing detection system based on UV light features and photon counting technologies. The test results show that the system can effectively make real-time detection on pantograph and catenary arcing state. Pantograph and catenary arcing state is associated with train speed, the greater the speed is, greater the rate of arcing and arcing strength will be.
