摘　　要：基于河慈4P67、河溪4P68碳纤维复合芯铝绞线(ACCC)在雨天和晴天的不同电晕放电情况,进行了实验室模拟试验,试验结果表明:在干燥情况下,相同截面的ACCC导线比普通钢芯铝绞线(ACSR)的起晕电压高;湿润状态下,相同截面的新ACCC导线比ACSR导线的起晕电压低。Based on the different corona discharge situations of HECI 4P67 and HEXI carbon fiber aluminum conductor composite core（ACCC） transmission lines in both rainy and sunny days,the simulation tests are carried out in the laboratory.The result indicates that the corona starting voltage of ACCC is higher than that of aluminum conductor steel reinforced（ACSR） transmission lines with the same section under dry condition,and the corona starting voltage of the former is lower than that of the latter with the same section under wet condition.
