利用配电自动化开关解决35 kV单线单变供电问题

Using Distribution Automation Switch to Solve 35 kV Single Line Single Transformer Power Supply Problem

针对部分经济欠发达、用电负荷较轻地区存在35kV单线单变供电结构薄弱、可靠性较低等情况,分析了主供线路永久性故障或主变故障时用户供电存在的问题,并对存在问题提出了依靠站内保护装置联切、配电自动化开关配合自动恢复用户供电的解决方案。

To the problem of the weak 35 kV single-line single-transformer power supply structure and low reliability in some areas with underdeveloped economy and light power load,the problems of user power supply in the case of permanent failure of the main supply line or main transformer failure are analyzed.For the existing problems,a solution to automatically restore the power supply to users by relying on the combined switching of the protection devices in the station and the automatic power distribution switch is proposed.
