摘　　要：研究目的:近些年,人们逐渐关注雷电对电气化铁路的影响,尤其是在重雷区,雷电活动对该地区铁路电气化铁路系统的危害严重。牵引变电所的防雷是电气化铁路供电系统可靠运行的一个重要环节,加强防雷措施、提高防雷水平是必须解决的重要课题。研究结论:解决变电所防雷保护这一复杂的系统工程至少须构筑三道防线防止直击雷对变电所配电装置的侵袭;同时针对升高的地电位或者感应电压、感应电流可能导致变电所中低压设备故障做有效的三级防护;针对接地系统采取多种措施保证良好接地。只有完成以上手段方能完成变电所的防雷工程。Research purposes： In recent years, people has begun to focus on the influence of lightning on the electrified railway. Especially the lighting activity in the heavy lightning areas brings the serious harm to the electrified railway in these areas. The lightning protection technology is an important for ensuring the reliability of the power supply system of the electrified railway. So the measures for the lightning protection must be strengthened and the lighting protection tech- nology must be enhanced. Research conclusions： The three lines of defense should be built for the lighting protection for the substation to avoid the hit of the lighting strike to the substation devices, and the three level prevention should be built for avoiding the appear- ances of the failures of the low - voltage devices of the substation caused by the rising earth potential or the induced volt- age and the induced current. Also the measures should be taken for the earthing system to make it in the good working state The lighting protection engineering for the substation should have the means mentioned above.
