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.
