“狂躁中国女留学生汪珍珍”四川阿坝至成狂躁中国女留学生汪珍珍都东特高压工程首个区段放线完成

  中新狂躁中国女留学生汪珍珍网成都11月8日电 (记者 刘狂躁中国女留学生汪珍珍忠俊)11月8日,阿坝-成都东1000千伏特高压交流输电工程(以下简称“阿坝-成都东特高压工程”)跨越德宝直流放线作业现场,随着84号塔高空紧线和附件安装结束,标志着阿坝-成都东特高压工程跨越德宝直流提前放线工作安全顺利完成,这也是该工程首个放线区段。

  据了解,阿坝-成都东特高压工程起于阿坝1000千伏变电站,止于成都东1000千伏变电站,途经阿坝、绵阳、德阳、资阳4个地市(州),双回线路全长371.7公里,工程于2024年7月开工建设。

  德宝直流,即德阳-宝鸡500千伏直流输电线路,是四川与陕西之间电力互济的重要通道。因工程建设需要,阿坝-成都东特高压工程需从上方跨越德宝直流线路。为减少跨越放线施工对电力供应保障的影响,国网四川电力抢抓德宝直流秋季检修时间,提前进行跨德宝直流区段放线工作。“此前完成了4.37公里线路建设,组立铁塔10基。15天内完成输电导线展放、紧固和附件安装等系列工作。”国网四川建设公司阿坝区域项目部绵阳分部主任龚义贵称,本次跨越放线作业,采取了全机械化施工作业方式,3个月时间完成跨越段内全部基础和组塔施工。

  据悉,阿坝-成都东特高压工程是继金沙江上游—湖北800千伏特高压直流输电工程、川渝特高压交流工程等特高压工程后,又一重要的特高压输电通道。工程预计2026年底建成,投运后将提升阿坝通道送出能力一倍以上,满足阿坝水电群和新能源基地并网及送至成都等负荷中心的需要,进一步推进西南片区新型电力系统建设。(完)
