毕业设计说明书 220kV横迳架空送电线路设计 学生姓名: 班级学号: 院、系、部: 电力工程学院 专 业: 电气工程及其自动化（输配电工程） 指导教师: 窦书星 实验师 合作指导教师: 2008年05月 南 京  摘 要 根据江苏省电力系统规划设计,拟从变电站新建一条220kV送电线路,向变电站供电。本设计由已知的气象条件、地理情况、材料参数等，对线路进行设计。设计书包括说明书、计算书、程序、杆塔与金具示意图四部分。主要内容有：导线、避雷线的应力弧垂计算；杆塔型式和金具的选择；杆塔室内定位；耐张杆塔荷载计算；转角塔塔材内力计算；基础稳定性校验；导地线的防振设计。设计书中简的说明了设计理论计算公式，给出了相关的设计图纸。本设计过程和内容与实际工程设计及施工较为接近，这种与实际相结合的设计对我们将来的工作有较大的帮助。同时采用CAD来绘制设计中相关的图纸。 According to electric power system in Jiang Su province programming design, draw up a transformer substation from Heng Ming set up a 220 kV power line road to send electric to Jing Tou transformer substation power supply. These designs have already known of weather condition, geography circumstance, material parameteretc, carry on a design to the circuit. The design book includes manual, the calculation book, procedure, pole tower and metals tool sketch map four-partcent. The main contents have: the calculation of lead line and avoid thunder line of the stress and the sag height; the choice of the pole tower pattern and metals tool; the pole tower indoor fixed position; the calculation of carry force on the tower of bearing; the calculation of tower material on the turn ape tower; the foundation stability check; design the lead line and avoid thunder line how to defend vibration of line. In the design book the elucidation of the synopsis design theories and calculation formula, list detailed of design contents, request and regulation, give related of design diagram paper. This design process and contents with actual engineering design and construction more close, this kind of with actual combine together of design to we future of work have bigger help. In the meantime, I use CAD to draw the related diagram paper in the design.. Key Words transmission design, the calculation of stress and the sag heig
