After side member to workstation 0 by towing power,front back,stop in workstation 0, As required by the heavy traction power to workstation 1, the plan for the introduction of electric motors with winch, configuration Steel (linked to a front-end) pegged to the starting motor in the flatbed truck towed to a public place.

大梁由牵引车头拖至零工位后，车头返回，平板车停在零工位，由于质量重需由动力牵引至一号工位，规划方案为采用电动马达带绞盘机构，配置钢绳挂在平板车上开动马达拖至一工位，行程距离约为15m，运行时蜂鸣警示器启动。

Firstly, the protection of direct lighting about traction substation is discussed. Secondly the excessive voltage made by wave of lighting is analyzed and some advices is given for it .Then a actual traction substation is computed and analyzed about it's excessive voltage, some problem should be considered in-depth are put out. At last , dependability of the measure of protection against lighting in this paper is analyzed.

首先研究了牵引变电所的直击雷保护，接着对雷电侵入波过电压进行了分析，并提出了雷电侵入波保护措施，然后以一个实际的牵引变电所为例对雷电侵入波过电压进行了计算和分析，并进一步指出了计算中应进一步考虑的若干问题，最后对本文提到的防雷措施的可靠性进行了综合的分析。
