摘要
在35 kV及以下电力系统中,电压互感器通常采用V-V接线方式。由于该种接线方式电压电流组合较为复杂,且向量图不够直观,因此接线错误出现的概率很大,且种类繁多。在分析当前各种错误接线检测方法的基础上,提出一种新的检测方法,并加以理论分析和实例验证。该方法简单直观,准确率高,能够在V-V错误接线分析工作中提高效率。
In the low-voltage power system under 35 kV, the potential transformers are commonly connected in V-V mode. In this mode, there is high probability and variations of faulty wiring because the combinations of voltage/current are very complicated, and the vector graphs are not intuitive. In this paper, a method for detecting and analyzing the faulty wiring in V-V mode is proposed. The theoretical analysis and instance validation prove the efficiency and accuracy of this method.
