采用计算机软件测控架空线路标准弧垂值的方法

标准弧垂是新建架空线路弧垂测控的重要依据之一。其弧垂值的获得一般是查设计部门提供的放线曲线。这种做法具有一定的人为误差。针对这一事实在弧垂测控中 ,采用了计算机程序计算标准弧垂值的方法。只要输入线路的基本参数和气象条件即可迅速计算出标准弧垂值。此方法可以极大提高弧垂测控的准确性 ,有效克服了人为误差 ,易于在施工和运行中推广使用。

Method to Improve Accuracy of Sag Measurement for Transmission Line Using Computer Software

The value of standard sag is an important factor to measure and control the sag of transmission line. To obtain the value the common way is to lookup the curves provided by the design departments. But the standard sag obtained by this way is prone to make a mistake. To overcome these defaults, this paper introduces a new method to calculate the standard sag by the computer. In case that the basic parameters and climate conditions of the line are input, the standard sag can be calculated quickly. This method can improve the accuracy of the standard sag, and overcome the artificial error. It is easy to be widely used in construction and operation.
