摘　　要：对不具备对侧电源的辐射状结构线路,由于没有可倒换电源,因此在出线电缆检修过程中,线路上用户往往在检修期陪停,导致巨大的时户数损失。针对这一城市改造过程中常见的工程场景,提出一种基于临时移动电源应用的首端出线电缆完全不停电检修方法,重点介绍了该方法的实施过程和应用优势。For radial structure line without opposite power sources,users on the line often suffer power cut during maintenance owing to lack of switchable power supply,resulting in a huge loss of user hours.In view of the aforementioned common engineering scenario in the process of urban reconstruction,based on the application of temporary mobile power sources,this paper proposes a maintenance scheme of head-end outgoing cable which can completely avoid power supply interruption.The implementation process and application advantages of this method are emphatically introduced.
