内容提要
此次毕业设计为110kV架空输电线路及其相关设计，线路路径为宝变110kV龙门架起至玉变110kV龙门架。该线路为新建线路，本次设计为满足线路的一次性架设。
本毕业设计是根据给出的原始资料（线路路径、导线型号、气象条件），为了绘制出应力安装曲线和应力弧垂曲线，我们需要对导线地线弧垂进行计算；绝缘子串及其金具型号数量，导线地线防振的设计，防雷接地设计；利用K值，画出弧垂曲线模板，利用它来进行排杆定位；从路径中的多个耐张段中选取一个，来对对其进行校验与检查，为了线路的正常运行及其使用的条件在正常范围内；线路走廊合理的处理；对杆塔结构型式确定。

Summary
The graduation project for the 110kV overhead transmission lines and related design, the route of the line for the treasure to change 110kV portal-type frame to the jade 110kV portal-type frame. The line is a new line, the design for the first time to meet the line.
This graduation design is according to the given original data (line path, the wire model and meteorological conditions) to complete wire cables sag calculation, the calculation results draw stress installation curve and stress sag curves; insulator string and fittings, type, quantity, ground lead anti vibration design, lightning protection and grounding design; the K value, draw the sag curve template, use it to locating the tower; from the path of multiple resistance to Resistance segmentselected , of the check and inspection for the line's normal operation and use conditions within the normal range; line corridor reasonable processing; types of tower structure determined.
