摘　　要：电压型配电自动化开关是目前配网自动化主流功能配置,其动作逻辑简单、可靠,与站内开关配合,能有效隔离故障点恢复非故障点供电。为了进一步发挥电压型配电自动化功能,减少非故障点停电时间,部分配网探索使用“闭锁分闸时间”配置。以电压分段器延时闭锁分闸动作逻辑原理及实例分析,对电压分段器延时闭锁分闸功能进行探讨,提出“闭锁分闸时间”仅对于单一故障有效,对于配网一段时间内前后发生多点线路故障,不但不能减少非故障点停电时间反而会扩大停电范围,定义“闭锁分闸时间”是无用功能配置,建议配网自动化开关不选用“延时闭锁分闸”功能。Voltage type switches are currently the mainstream configuration in distribution network automation.Its action logic is simple and reliable.Cooperating with switches in the substation can effectively isolate fault points and restore power supply to non fault points.In order to further leverage the power distribution automation function and reduce the power outage time at non fault points,some distribution networks are exploring the use of a"locked opening time"configuration.This article explores the delay locking and opening function of the voltage segmented device based on the logic principle and example analysis of the delay locking and opening action of the voltage segmented device.The proposal of'blocking and opening time'is only valid for a single fault.For multiple line faults that occur in the distribution network before and after a certain period of time,not only does it not reduce the power outage time at non fault points,but it will also expand the power outage range.The definition of"locking and opening time"is a"chicken rib"functional configuration.It is recommended that the distribution network automation switch not use the"delayed locking and opening"function.
