摘　　要：因为铁路10 kV电力线路中的中性点大都不进行接地处理,所以难以达到良好的绝缘水平,在感应雷过电压作用下便会出现变电站跳闸甚至电力设备损坏的情况。因此,为有效避免此类情况的发生,分析了铁路10 kV电力线路中的感应雷击防跳闸技术,希望通过本次的分析可以使感应雷击对10 kV铁路电力线路正常运行的不利影响得以有效降低,保障铁路电力供应的安全稳定进行。Because many neutral points in railway 10 kV power lines are not grounded,it is difficult to achieve a good insulation level.Under the action of induced lightning,substation tripping and even power equipment damage will occur.Therefore,in order to effectively avoid the occurrence of this kind of situation,this paper analyzes the induction lightning trip prevention technology in railway 10 kV power line.It is hoped that through this analysis,the adverse impact of induced lightning on the normal operation of 10 kV railway power lines can be effectively reduced,and the safety and stability of railway power supply can be guaranteed.
