摘　　要：阐述了城区台架变取消柱上跌落式熔断器后的优化方案,即在电源接入点配电房内安装负荷开关+熔断器组合柜对台架变供电,并从熔断器参数、保护范围及要求等方面论述了优化方案的可行性。The optimization plan after the drop-out fuse on the column was eliminated in the urban substation transformer was described,that is,the load switch+fuse combination cabinet was installed in the power distribution room at the power access point to supply power to the bench substation.At the same time,the feasibility of the optimization scheme is discussed from the aspects of fuse parameters,protection scope and requirements.
