摘要
受电弓-接触网系统是电气化铁路的重要组成部分,也是电气化列车获取电能的唯一途径.弓网燃弧作为弓网系统受流质量评价的重要指标,有着检测便捷、评估直观的优势,由此衍生出多种燃弧检测方法.针对当前的不同燃弧检测方法,将其归纳为直接检测与间接检测 2 类.直接检测主要指基于电流、电压等电气参数的燃弧直接测量,间接检测主要包含基于声学、光学和电磁辐射等特性的远距离测量.针对以上的不同检测方法,详细论述了其应用场景、检测基本原理及相应的评判方法.在此基础上,综合分析了不同检测方法的优劣,并结合燃弧检测的相关标准,讨论了标准中有待改进和完善的地方以及燃弧检测后续研究的主要方向与发展趋势.
Abstract
The pantograph-catenary system is an essential and integral component of electrified railways,providing the only way for electric trains to obtain power.The arcing of the pantograph-catenary system is a crucial indicator for assessing the current collection quality of the system,with the benefits of convenient detection and intuitive evaluation leading to the development of va-rious arcing detection methods.These methods can be classified into two categories,direct and indirect detection.Direct detection involves the direct measurement of the arc based on electrical parameters such as current and voltage,while indirect detection in-cludes long-distance measurement based on characteristics such as acoustics,optics,and electromagnetic radiation.This paper provided a detailed discussion on the application scenarios,basic detection principles,and corresponding evaluation methods of these different detection methods.Furthermore,a comprehensive analysis of the advantages and disadvantages of these methods was presented,along with a discussion on the areas for improvement and enhancement of relevant standards for arc detection,as well as the main directions and development trends of subsequent arc detection research.
