摘　　要：碳纤维复合芯导线是最常见的增容导线之一,工程应用越来越多,但国内外关于碳纤维复合芯导线的舞动特性及受损特征的研究较少。针对该问题,本文建立了舞动试验观测档线路,通过安装并调节人工模拟冰,实现了碳纤维导线的舞动模拟,完成了自然风激励下碳纤维复合芯导线与普通导线的舞动试验对比,试验结果表明:在低风速时,碳纤维复合芯导线舞动的动态张力比普通导线小;当高风速时,碳纤维复合芯导线舞动的动态张力比普通导线大;高风速时,碳纤维复合芯导线的舞动幅值和动态张力容易被低估。同时,本文利用导线舞动模拟试验机,开展了碳纤维导线的舞动疲劳试验,结果表明:碳纤维复合芯导线在舞动条件下会发生导线单丝断股、金具磨损等故障,需要重视冬季舞动后导线线夹部位的检修检查,及时发现并排除故障。There are more and more studies and applications of ACCC（aluminum conductor carboncore）in the power system currently. However,there are few studies on the galloping characteristics anddamage characteristics of ACCC at home and abroad. A galloping experimental observation span was es-tablished,where the simulated galloping of ACCC was achieved by installing and adjusting the artificialice. Comparing the agitation test of ACCC and common conductor under natural wind excitation,the testresults show that： The galloping characteristics was found compared with ordinary wire that a ACCC has aless galloping-strength under low speed wind;a higher galloping-strength under high speed wind;Athigh wind speeds,ACCC＇s dance amplitude and dynamic tension are easily underestimated. Meanwhilea transmission line galloping-simulating machine is invented and used for fatigue test on the condition ofgalloping for ACCC,the test results show that： ACCC wire under the conditions of galloping wire monofil-ament strand break,metal wear and other faults,need to pay attention to the winter dance after the wireclip repair and inspection,timely detection and troubleshooting.
