摘　　要：在已有的防雷措施的基础上,参照电力系超高压防雷的措施,提出了针对铁路的防雷击的保护新方法,即采用相对固定距离保护间隙与氧化锌避雷器串联后再与线路绝缘子并联。能够结合断路器及自动重合闸等继电保护装置有效对10 kV铁路线路在遭受感应雷击的情况下进行保护,有效减少停车事故。Based on the lightning protection countermeasures taken in the past tor railway electric power system and consulting the lightning protection countermeasures taken in the high voltage and extra high voltage power system, the new lightning protection method aiming to railway power system is presented, i.e., an external air gap is in series with a metal Oxide surge arrester ,（MOA） as a lightning protection device, which is then in parallel with the line insulator across a relatively fixed distance. Such device can provide the protection against the induced lightning on the lOkV railway power lines combined with circuit breaker, auto reclose and relay protection devices, and reduce effectively the compulsory parking accidents.
