1、毕业设计说明书35kV格塘架空送电线路设计专业：电气工程及其自动化（输配电工程）UndergraduateDesign(Thesis)THEDESIGNOF35kVGETANGOVERHEADTRANSMISSIONLINEBYSupervisedbySchoolofElectricPowerEngineeringNanjingInstituteofTechnologyJune2013摘要本设计根据格塘线段地形，气候等各种因素来计算导线、避雷线的应力以及弧垂，由此来绘制弧垂曲线图。然后根据设计要求依

2、次选择杆塔型式，包括确定直线杆杆型、选择绝缘子串型号规格及其金具，选择避雷线规格及其金具，确定杆塔呼称高，确定杆头尺寸，确定电杆的埋深以及确定耐张杆杆型和选择耐张绝缘子串型号规格及其金具，选择避雷线的连接金具，确定耐张杆的呼称高和杆头尺寸，确定电杆埋深等一系列步骤；其次根据计算得到的结果制作一张弧垂曲线模板，根据模板进行杆塔的室内定位并绘制成图纸；接着进行耐张杆杆头的尺寸校验和耐张杆的强度及基础的稳定性设计；最后再对线路各段进行防振设计。关键词应力弧垂，设计，架空送电线路AbstractThearc
