基于紫外脉冲原理的地铁弓网燃弧检测系统研究

摘要

Arcing detection device based on the principle of non-contact pulsed UV is used for arcing appeared frequently on north extension of Guangzhou metro line 3, and real-time monitoring, and test data are analyzed and processed. The paper studies the idea of the evaluation system established for the pantograph and catenary interface under rigid suspension conditions, and it provides theoretical references for future line maintenance and renovation.%　　在国内外弓网燃弧检测技术研究的基础上，研究分析了弓网燃弧的光谱特性，成功研制了基于紫外脉冲原理的非接触式弓网燃弧检测系统。利用该检测系统对广州地铁3号线北延伸段频繁出现弓网拉弧现象进行实时检测，并对检测数据进行分析，探讨了刚性悬挂条件下建立弓网关系评价体系的思路，为以后的线路维护及改造提供理论参考。
