摘　　要：锡盟—泰州±800 kV高压直流输电线路工程,首次采用8×JL1/G2A-1250/100大截面导线,为保证线路安全可靠运行,对典型塔ZC30103B进行真型实验,对其安全可靠进行了验证,并对其在控制工况下破坏过程的位移、应变以及破坏情况进行了分析。实验表明,ZC30103B塔设计安全、经济,实测值与理论值吻合,满足工程实际需要。For the Ximeng-Taizhou±800 kV UHV DC transmission line project,8×JL1/G2A-1250/100 large cross-section conductors were used for the first time.In order to ensure the safe and reliable operation of the line,a true type test was carried out on the typical tower ZC30103B to ensure its safety The reliability was verified,and the displacement,strain,and failure of the failure process under controlled conditions were analyzed.The test shows that the ZC30103B tower is designed to be safe and economical,and it is destroyed at the expected overload value.The measured value is consistent with the theoretical value and meets the actual needs of the project.
