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,若上级进线电源需更换、检修和迁移,低压终端用户需要陪同停电,居民群众用户用电满意度则会受到严重影响。针对这一现状,提出一种基于临时移动电源应用的低压侧短时停电的箱式变压器更换方法,极大地降低了低压陪停电时户数损失,有效提高了供电可靠性和电力营商环境。重点介绍了该方法的实施过程和应用优势。
Box-type transformers sometimes serve as the only power source of the low voltage end users in a radial distribution structure.In that case,replacement,repair and migration of power source from upper progressive line causes accompanying power outage to low voltage users,seriously affecting satisfaction degree of residents.In view of this situation,a new replacement method of box-type transformers enabling shortened outage duration on low voltage side was proposed in this study,which was realized by utilizing temporary mobile power source.The method can facilitate great reduction in outage-induced user losses and effective improvement of power supply reliability and power business environment.The implementation process and the application advantages of this method are outlined in this paper.
