摘要
为了提高铁路牵引供电系统安全防护等级,加强防范强电侵入的能力,减少雷击事故对铁路运输以及设备维护造成的经济损失,本文分析了牵引变电所常见的强电侵入类型及途径,针对现有问题逐一提出了优化技术方案,并阐述了研究思路及方案具体实施方法。
In order to improve the level of safely protection of railway power supply system so as to strengthen ihe ability to prevent sirong electric intrusion and to reduce economic losses caused by lightning accidents on railway transportation and equipment maintenance,the types and paths of strong electric intrusion in substations are analyzed.A technical optimum solution is proposed for the existing problems and its research ideas and specific implementation methods arc also described.
