摘要
针对±500 kV兴安直流线耐张线夹断裂故障进行分析,根据检查和试验结果可知,该导线的上扬耐张线夹极易发生积水,存在锈蚀断裂隐患。对此提出了大线径导线耐张线夹锈蚀断裂防范措施,对新建、已投运的大线径导线的安全运行、设备改造以及新线路设计具有指导意义。
The fracture fault of the tension clamp in±500 kV Xing’an HVDC transmission line is analyzed.Based on the check and test results,it is known that the water is easily accumulates in the upper tension clamp which has the hidden trouble of corrosion fracture.The prevention measures for the corrosion fracture of the tension clamp in the large diameter conductor are proposed which has guidance significance to the security operation of new and operation large diameter conductors,the equipment modification and the design of new lines.
