随着我国经济不断发展,铁路行业的发展也越来越迅速,尤其是近些年高速铁路的飞速发展,大大提高了人们出行的速度,减少路上的的时间。而在高速铁路的各项维护防护中,牵引供电系统是否正常运行相当重要;被雷击中损失巨大,在牵引供电系统导致众多故障原因中,雷击问题是主要问题之一。鉴于这种情况,本论文先对目前高速铁路牵引供电系统雷电防护中存在的问题进行了详尽的阐述,对高速铁路雷击所导致绝缘子闪络的各种原因进行了分析,对高速铁路牵引供电系统雷电防护的措施和措施进行讨论。
With the continuous development of economy in our country, the development of the railway industry is also becoming more and more rapid. Especially in recent years, the rapid development of high-speed railway has greatly increased people’s travel speed and reduced the time on the road. It is very important for the traction power supply system to operate normally in various maintenance and protection of the high-speed railway. The loss caused by the lightning stroke is huge. Among the many causes of the traction power supply system, the lightning stroke problem is one of the main problems. In view of this situation, this paper firstly elaborates on the existing problems in lightning protection of the traction power supply system of high-speed railway, and analyzes various reasons of insulator flashover caused by lightning strikes on high-speed railway. Lightning protection measures and measures for discussion.
