摘要
虽然利用圆形填充条代替网状撕裂绳填充能够让电缆的结构更加圆整和稳定,但在选择填充条直径时却难以通过手工快速计算,且不同成缆直径电缆的填充条直径也不同,导致其计算不仅费工费时,还难以计算准确。为了保证电缆成缆圆整性,准确计算出m+n(m≥n≥1)绝缘线芯结构电缆成缆直径和填充条直径是非常必要的。根据几何原理推导出m+n绝缘线芯结构电缆成缆直径和填充直径的计算公式,利用Excel软件中的"规划求解"功能,实现了快速准确的成缆直径和填充直径计算。
Though using round filling strip instead of reticulation rip cord can make the structure of the cable rounder and more stable,it is hard to manually calculate the diameter of filling strip fast.Moreover,different cable has different filling strip diameter,which makes the calculation not only time-consuming but also difficult to calculate accurately.In order to ensure the roundness of cable-laying,it is necessary to calculate the cable-laying diameter and filling strip diameter of cable with m ＋n（m ≥n≥1）insulated conductor accurately.Based on the geometrical principle,the formula of cable-laying diameter and filling diameter is deduced.Using Excel＂solver add-in＂,quickly and accurately calculating the cable-laying diameter and the filling diameter is realized.
