架空线路导线交直流电阻比的分析与研究

摘要

导线的交流电阻是在电流方向交变的情况下,由于电、磁相关因素的共同影响,在导线直流电阻的基础上增大而产生.本文就选取摩根算法,对多种钢芯铝绞线的交直流电阻比进行计算,根据计算结果分析了交直流电阻比和导线的温度、截面积、层数之间的关系.对导线的选型和经济性的比较均有参考价值.%AC resistance is generated on the basis of DC wire resistance under electric and magnetic influence in case of alternating cur-rent direction.ACSR variaty rate of AC-DC resistance data is calculated by Morgan algorithm.The results show the relationship of rate of AC-DC resistance,temperature and its structure,which has reference value in wire selection and economic comparison.
