随着我国经济的发展,电力工业也在快速增长,城网、农网需要改造来适应时代的发展。弧垂是衡量高压输电线路铺设安全运行的标准,它的大小对线路的安全运行至关重要。而传统的弧垂计算公式数据多、较为复杂,在进行操作时容易出现错误,而且计算周期很长。而碳纤维复合芯具有密度小(碳纤维复合芯的密度仅为普通钢芯的1/4)、抗拉强度大(碳纤维复合芯的抗拉强度可达2400MPa,可达普通钢芯的2倍)、耐热性好(碳纤维复合芯高温下的伸长率远小于普通钢芯)等特性。因此,需要借助计算机来进行弧垂计算软件设计。传统的导线只适用于普通的弧垂计算,并不适用于新的于碳纤维复合芯导线[1]。借助VB编程实现碳纤维复合芯导线弧垂计算软件设计与开发至关重要。
