摘要
随着高速铁路大规模成网运行,接触网分布范围日益扩大,异物挂网引发的安全事故逐渐增多,成为影响高速列车行车安全的重要因素之一.目前,针对接触网侵限异物的检测与挂网异物的清除方法研究颇少,而电力系统输电线路异物检测、清除的研究成果颇丰.详细综述了接触网侵限异物检测技术的原理、方法以及在铁路领域的应用,重点分析了不同方法的适用场景和优缺点.同时,借鉴电力系统领域异物清除技术研究,重点探讨了挂网异物清除技术的原理、特点,以及在接触网清异的可能性及局限性,结合接触网的特点和运维需求,从远距离实时检测、远距离快速清除以及检测清除装置的小型化与轻量化3个方面,探讨了接触网异物检测清除技术未来的发展方向.
Abstract
As the operating miles of high-speed railway increase,incidents of foreign object intrusion are gradually grow-ing,which have become one of the main factors affecting the safety performance of high-speed railways.The research is insufficient in terms of intrusion detection and hanging foreign object removal methods with respect to overhead contact line,while similar work on power transmission lines is considerably fruitful.Therefore,this paper provided a detailed re-view of existing research on intrusion detection technologies,from the perspectives of detection principles,detection methods and their applications in railway system,with a focus on analyzing the applicable scenarios,advantages and dis-advantages of different methods.Drawing on the works on hanging foreign body removal technologies in power systems,this paper investigated the principles and characteristics of hanging foreign body removal technologies,as well as the possibilities and limitations of their applications in overhead contact line.Combined with catenary characteristics and op-eration and maintenance requirements,the development direction of foreign object detection and removal technologies for overhead contact line was discussed from the three aspects of long-distance real-time detection,long-distance rapid re-moval,and miniaturization and light-weighting of detection and removal devices.
