摘要

用户事故出门是导致配电网事故跳闸的主要原因之一

影响了配电网的供电可靠性。在分析配网用户事故出门情况及特点的基础上

探讨了在分支线增设保护装置的必要性

并提出了在配网分支线增设熔断器保护的方法。该方法可降低配网事故跳闸次数、保证配网连续可靠运行并且可减少配网线路故障巡查。

Abstract

As one of primary causes of switch trip in distribution feeders

extended fault from user lower the power supply reliability of distribution networks.This paper analyses the necessity of installing protection on the beginning of sub-feeders

and presents a method of installing fuse protection on sub-feeders.It is of great significance to decrease fault-trip times

assure reliable operation and lessen inspection workload for distribution systems.
