摘　　要：在部分城区输变电工程中,由于城市现有发展、未来规划等原因,已无法开辟新的高压架空线路走廊,只能利用已建线路路径进行升级改造。对这类高压线路工程,通过新旧线路通道整合、导线电磁环境的优化、增容耐热导线的选择、建设时序及临时过渡方案的设计、铁塔选型及基础施工等措施,达到满足城市规划、缩短建设工期、优化环境指标、降低工程投资的目标,使工程具有更好的技术经济指标,本研究可供类似工程参考和借鉴。In some urban power transmission and transformation projects,due to the existing development and future planning of the city,it is no longer possible to open up new high-voltage overhead line corridors,and only existing line paths can be used for upgrading and renovation.For this type of high-voltage transmission line project,measures such as integrating new and old line channels,optimizing the electromagnetic environment of the conductors,selecting heat-resistant conductors for capacity expansion,designing construction schedules and temporary transition plans,selecting tower types and foundation construction are taken to achieve the goals of meeting urban planning,shortening construction period,improving environmental indicators,and reducing project investment,so that the project has better technical and economic indicators,which can be used as a reference and reference for similar projects.
