摘　　要：当箱式变压器作为唯一电源,以辐射状结构向低压终端用户供电时,如果上级进线电源需更换、检修和迁移,低压终端用户就要陪同停电,居民群众用户用电满意度将受到严重影响。特别是对于某些重要用户,亟需一种能够实现完全不停电的箱式变压器更换方法。针对这一现状,提出了一种基于临时移动电源应用的低压侧完全不停电的箱式变压器更换方法,消除了低压陪停电时户数损失,有效提高了供电可靠性和改善了电力营商环境。重点介绍了该方法的实施过程和应用优势。Box-type transformers usually serve as the only power sources for low voltage end users in a radial structure,and under this condition the replacement,maintanence or migration of upper lead-in source will cause power outage of the low-voltage users and severe impact on user satisfaction.Especially for some important users,there is an urgent need for a outage-free replacement method for box-type transformers.In view of this a method utilizing a temporary mobile supply source is proposed and described in this paper,which can address the aforementioned problem.
