摘要
针对现场存在的轨旁信号设备与接触网支柱接地点间距较近的情况,分析信号设备遭受雷害概率增加的原因;提出利用增加接地极的方法,增加轨旁信号设备与接触网支柱之间的接地间距,从而降低雷害对信号设备的影响。
As for short distance between the trackside signal equipment and the grounding elec- trode of the catenary post, the reason why the probability of damages to signal equipment due to lightning increases is analyzed. It is proposed that the distance between the trackside signal equip- ment and the grounding electrode of the catenary post can be enlarged by adding extra grounding electrodes, thus reducing the influence of lightning damage on the signal equipment.
