用电压抽取装置检测35kV线路电压供备自投使用

Measuring the voltage of 35 kV power line with two capacitor-votage detecting devices

介绍一种用110～220kV线路电压抽取装置检测35kV线路电压(供备自投使用)的方法。实践证明该法简单、可行、节省投资和安装空间,在老站进行综合自动化改造中,该方法尤为适用。

This paper presents a new method for measuring the voltage of 35 kV transmission line with two capacitor-voltage detecting devices designed for 110～220 kV transmission line.The voltage is used for a reserve power source automatic connection device. Engineering application shows that the proposed method is simple, feasible, and money-and-space saving . Especially,the method is suitable for old substation's automation rebuilding.
