首都核心区电力架空线入地工程全面推进

2017-07-26 09:45:13   千龙网

【编者按】2017至2020年,北京在全市范围内组织开展“疏解整治促提升”专项行动。疏解,是为城市治理、去病除疴做“减法”;提升,是为腾笼换鸟、留白增绿做“加法”。疏解整治促提升,带来的将是更加和谐宜居的北京。2017年已经过半,“疏解整治促提升”专项行动交出亮眼成绩单。千龙网记者深入北京市十六区街头巷尾,见证疏解与提升给市民带来的切实变化。

随着北京“疏解整治促提升”进程的加快,今年6月以来,首都核心区电力架空线入地工程进入全面实施阶段。晚上10点至次日5点,每天历时7小时的夜晚战斗,争分夺秒的不眠夜,让入地工程全面提速。

截止目前,首都核心区内樱桃胡同、西直门南小街、樱桃斜街等6条街道均完成改造,实现送电投运和撤线拔杆。今年,国家电网北京市电力公司将对首都核心区64条道路两侧的架空线路进行入地改造,线路共计61.14公里,整体工作量达到“十二五”期间全部工作量的5倍。

至“十三五”末,首都核心区电网电缆化率将由目前的90.2%提升至94%,供电可靠率提升至99.999%,年户均停电时间低于5分钟,首都核心区将打造成为“安全可靠、智能互动、绿色低碳、环境友好”的国际高端智能配电网示范区,达到国际领先水平。

施工全程应用“移动智慧工地”技术

7月25日夜间11点,千龙网记者来到了正在进行电力架空线入地施工的景山东街,现场近百名工作人员正在紧张作业。记者从现场了解到,目前正在施工的包括景山周边的6条道路,目前均已完成围挡搭建,半数以上正在进行土方开挖。

据北京城区供电公司副总经理魏世岭介绍,电力架空线入地工程主要包括两大块工作:一是“建”,二是“拆”。以景山为例,电力公司总共要拆除电力架空线路约3.46公里,柱上变压器17台,拔除线杆179基。同时,新铺设地下电缆8.44公里,安装10千伏箱式变压器和开闭器28台。“目前施工进展良好,景山区域入地工程预计将在10月中旬全部完工。”
