摘要
南方电网公司建设投产直流电压等级最高的云广±800 kV直流输电工程,采用LGJ-630/45大截面导线,每极按六分裂布置,为防止导线在大跨越档放线过程中发生嵌套绞线,提出了3种解决方法及注意事项。在云广直流28.1标段得到了有效实施,确保了施工安全和工程质量。
±800kV Yunnan-Guangdong DC transmission engineering is the highest voltage degree constructed by North Power Grid Corporation,it adopts LGJ-630/45 large cross-section conductor with six-multiple each degree.In order to avoid nesting twisted line during large crossing span setting-out process,the paper proposes three solutions and its notices.After implementing it into 28.1 bid lot of Yunnan-Guangdong DC transmission line,it ensures construction safety and engineering quality.
