Replacement of Box-type Transformers with Shortened Outage Duration by Using Temporary Mobile Power Source
Box-type transformers sometimes serve as the only power source of the low voltage end users in a radial distri-bution structure.In that case,replacement,repair and migration of power source from upper progressive line causes ac-companying power outage to low voltage users,seriously affecting satisfaction degree of residents.In view of this situa-tion,a new replacement method of box-type transformers enabling shortened outage duration on low voltage side was pro-posed in this study,which was realized by utilizing temporary mobile power source.The method can facilitate great reduc-tion 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.
