架空线路导线及地线的要求对架空线路导线及地线的要求主要有以下方面：材料要求、线间距离要求、弧垂要求、对地及交叉跨越要求、导、地线间的连接要求、导线与地线的配合要求等。

总体要求为：选择具有良好电气性能和机械性能的材料，保证安全可靠的运行参数（限距、弧垂等），采用合理的施工工艺。

一、对导、地线材料的要求：1、对导线材料的要求：导线的功能和工况一一传输电能，通电、承受机械荷载。

对其材料的基本要求为：具有良好的导电性能及足够的机械强度，并具有一定的耐腐蚀、耐高温和可加工性能，且重量轻、性能稳定，耐磨损，价格低廉等。

能满足上述要求的材料主要为铝和钢，前者导电性能好但机械强度较差；后者则导电性能差而机械性能好。

因此目前大多用这两种材料组合制作导线，如钢芯铝绞线等。

2、对地线材料的要求：架空地线的作用：引雷入地，减少雷击线路而跳闸的机会，提高线路的耐雷水平，保证线路安全送电。

架空地线的类别:普通架空地线一不与杆塔绝缘，只起引雷入地的作用；绝缘架空地线一与杆塔绝缘，起引雷入地的作用，还可作载波通讯的通道、地线自身的融冰、检修时电动电源及小功率用户的供电等对普通架空地线材料：只要求有较高的机械性能及良好的耐腐蚀性能，一般采用钢绞线。

对绝缘地线材料：较高的机械性能、良好的耐疲劳性、耐腐蚀性能及良好的导电性。

一般采用钢芯铝绞线、铝镁合金绞线和铝包铜绞线等。

以降低通讯衰减，提高通讯质量。

二、导线的线间距离要求：导线的线间距离主要指导线间的水平距离、垂直距离和水平偏移距离。

确定的依据一一保证足够的电气间隙，确保导线之间及导线与杆塔接地。

导线的线路间距离主要取决于以下情况：1)导线风偏后对杆塔的最小空气间隙应满足规程要求；2)档距中央导线之间不得发生闪络和鞭击现象。

实践证明：对110kV以上的线路：因为其绝缘子串较长，风偏角大，其线间距离一般由第一种情况控制。

对110kV以下的线路：绝缘子串较短，而档距中央弧垂最大，故以第二种情况来限制导线间的距离。

[架线]导地线各种弧垂的含义及计算方法（附计算表格），彻底弄懂弧垂01-导地线各种弧垂的含义弧垂，又叫弛度，行业外叫“挠度”。

一般定义为：导线悬挂曲线上任意一点到两侧悬挂点连线之间的垂直距离（即任意点弧垂）。

在工程设计、施工、运行中，涉及到观测弧垂、竣工弧垂、平视弧垂（分小平视弧垂和大平视弧垂）、任意点弧垂、最大弧垂、中点弧垂和百米弧垂等诸多术语。

我们施工平时常用的弧垂，有观测弧垂、竣工弧垂、百米弧垂。

为方便初学者使用，将各种弧垂的含义逐一解释如下。

1）观测弧垂，就是某一温度下，现场观测时需要达到的弧垂。

高差不大的情况下，观测弧垂=竣工弧垂，只有连续倾斜地形工况下，才需要区分观测弧垂和竣工弧垂。

施工时，需要根据设计图纸要求，先计算竣工弧垂，然后根据计算出来的竣工弧垂，进一步计算出观测弧垂和线夹安装位置调整值（俗称“爬山值”）。

当导地线弧垂稳定达到观测弧垂时，停止紧线，开始进行附件安装，直线塔附件安装时，需要对线夹安装位置进行调整，也就是说线夹安装的位置不一定是导线与滑车的中心，正常线夹安装完毕，悬垂串应呈竖直状态，各档的弧垂由观测弧垂值变成竣工弧垂值。

观测弧垂、紧线弧垂、施工弧垂，基本上都是同一个意思。

孤立档的观测弧垂，在以前，孤立档或构架档紧线，是一端挂好耐张瓷瓶串，然后在另一端不带瓷瓶串紧线，弧垂紧到设计所规定的紧线弧垂时，再将耐张瓷瓶串挂到导线上，由于瓷瓶串自重比载往往比导线重很多，弧垂会发生变化。

紧线完毕挂耐张串前的弧垂，称之为观测弧垂、紧线弧垂或施工弧垂，两侧瓷瓶串均安装完毕后的弧垂，叫竣工弧垂。

如今的紧线施工工艺，是两端均带瓷瓶串紧线，其中一端事先压接完毕，另一端通过卡线器、钢丝绳短套临时与瓷瓶串金具连接，紧线完毕画印、断线压接，然后过牵引挂到金具上，弧垂直接定型，直接达到竣工弧垂。

2）竣工弧垂，附件安装完毕之后的弧垂值，是与观测弧垂、紧线弧垂、施工弧垂相对而言的。

通过上面观测弧垂的阐述，相信大家已经有了初步的理解。

“输电线路导、地线张力弧垂及杆塔荷载计算程序”使用说明书江苏省电力设计院2008年10月11日前言杆塔承受的电线荷载，就是电线通过悬挂点施加到杆塔上的力。

该力在无风情况下通常分解为相互垂直的三个分量，即竖向垂直荷载TG、纵向张力荷载TQ（顺线路方向的水平张力）、横向张力荷载TS（垂直于线路方向的水平张力，包括通过电线传递的风荷载）。

电线荷载一般需计算5种工况(覆冰、大风、不均匀脱冰、事故、安装)下的荷载，对于钢管塔还需考虑大风上拔，必要时杆塔设计还要校验验算工况。

在各种工况下组合垂直荷载、纵向荷载、横向荷载是一个很繁琐的过程，简单的靠人工或电子表格计算工作量大，且很容易出错。

“输电线路导、地线张力弧垂及杆塔荷载计算程序”集成了导地线张力及弧垂计算和杆塔荷载计算的功能，只需输入最原始的设计参数，计算结果可直接的以图形或表格的方式输出，直观且提高工作效率。

根据《110~750kV架空输电线路设计规范》（国标报批稿）、《架空送电线路杆塔结构设计技术规定》（DL/T 5154-2002），并参照《电力工程高压送电线路设计手册》（第二版，以下简称《手册》）和我院原“500kV杆塔荷载计算程序”的有关公式，结合杆塔设计的经验，编制了本程序。

其特点如下：1．与导地线张力计算绑定编程，避免了开列杆塔荷载时导地线参数和气象条件的多次重复输入，无需借助于其它软件便可独立完成导地线的张力及荷载计算；2．设置了导地线、气象区及绝缘子串型数据库；3．具有计算数据自动保存和读取Excel荷载计算书中设计参数的功能，如要修改原荷载中某数据，只需操作“读取杆塔数据”按钮，修改某数据后再进行计算，无需再次输入全部数据，操作方便、快捷；4．荷载表中列出了导地线参数、气象条件、绝缘子、金具、线路参数及中间数据，同时在Excel上设有自校验功能，可从中获取荷载的详细计算公式，便于校核；5．可同时计算6组导、地线力学特性和架线弧垂表，生成的CAD图表可直接出版；6．可计算三层导线及地线，双回路塔的荷载可一次性开列完成。

本工程的导地线配合计算结果见附图，图一和图三以2D-ZM1塔的塔头数据参与计算，图二和图四以2D-ZMC2塔的塔头数据参与计算，由附图可以看出，不论是JLB40-120地线还是GJ-50地线，其安全系数均不宜大于3.2。
