“JK裙子全开襟做运动网站”山西南部一JK裙子全开襟做运动网站500千伏超高压线路经防覆冰改造后投运

  中新JK裙子全开襟做运动网站网太原12月2日电(高雨JK裙子全开襟做运动网站晴 杜衡 李文霞)记者12月2日从国网山西超高压输电公司获悉,当日14时56分,国网山西省电力公司重点工程——500千伏风运一线经防覆冰改造后投运,标志着山西省内超特高压输电线路防覆冰改造工作取得阶段性胜利,为迎峰度冬电力保供打下坚实基础。

  500千伏风运线全长15.194公里,位于山西省运城市芮城县中条山山脉,属微地形区,常年因气候及极端恶劣天气等因素,给输电线路造成极大安全隐患,并给电网带来诸多不稳定的因素。

  为此,国网山西省电力公司克服高山大岭、运输困难、大风寒潮等因素,新建41基铁塔,拆除原风运一线两相导线12.1公里,拆除双回路导线1.55公里。通过此次改造项目的实施,有效提高输电线路的稳定性,保障电网的安全稳定运行。

  由于该工程改造区段全部位于高山大岭,材料、机械运输变得异常困难,加之改造区段全部位于风口,进入冬季后,大风天气始终不断,这给工期的按时完成带来不小挑战。

  其间,国网山西超高压输电公司集中调配5个分部、2个中心32名安全管控“明白人”,配合已成立的业主项目部重点对铁塔组立、牵张场布置、紧放线通讯联络、导地线压接等现场进行安全管控、质量监督、进度监督,确保每一个作业点均有人管控,作业现场安全能控、可控、再控。

  国网山西送变电公司克服地形差、气温低等不利因素,高质量推进抗冰设备安装、覆冰区段加固、线路抗压能力提升等关键工序,创新实践“分层钻爆结合保护网”“模块化组装+高空滑轮吊装”等先进工法,大幅提高作业效率。(完)
