摘　　要：分析了在铁道中使用线路避雷器的利弊,提出了可使用的范围,并对避雷器对接触网的防雷保护作用作了详细的说明。指出列车在遭受雷击时,人在列车内不会遭到雷击,对线路绝缘子全线加装避雷器的方法不可行。The advantages and disadvantages of line arrester in the railway were analyzed, and the usable scope were put forward. And the lightning protection function of arrester on contact networks was introduced in detail. It was pointed out that if the train was in shock, people won＇t be struck in the train. At last, it pointed out that it is not feasible to equip line insulator with arrester in the whole line.
