摘　　要：线路弧垂是输电线路安全运行的重要指标,传统的弧垂测量方法在特殊地形、线路带电、台账缺失等情况下往往无法开展,计算弧垂时往往还需手工计算,计算量大,易出错。为此,文章介绍一种在档外视野范围内测量弧垂的新策略,称为“两点法”。此方法推出最大弧垂计算公式后,再运用java语言编写计算程序实现。应用该方法时只需两导线悬挂点在视野范围内,不受地形、线路运行情况及线路台账已知等条件限制,具有易操作、易实现、结果准确等优点。Line sag is an important indicator for the safe operation of transmission lines.Traditional sag measurement methods are often unable to be carried out under special terrain,live lines and missing accounts.When calculating the sag,manual calculation is often required,which is laborious and error-prone.In view of this,the paper introduces″two-point method″,a new strategy for measuring sag in the field of vision outside the gear.The formula is derived and then realized via java programming.This method only requires that the two wire suspension points are within the field of view,but it is not restricted by conditions such as terrain,line operation conditions and known accounts.Therefore,it has the advantages of easy operation,easy implementation and accurate results.
