摘要：针对电压互感器二次回路防止误接线的方法进行了探讨。首先介绍了影响选择电压互感器二次绕组的主要参数及常见接线方式；然后提出了电压互感器投运前和运行中应注意的事项；最后提供了两种实用方法，从接线前和接线后两个方面分别对二次回路进行检查，以判断二次回路接线是否正确。研究结果表明，该方法具有广阔的推广应用前景。

Abstract: The method of prohibit wrong wiring for the PT secondary circuit was simply introduced. The main parameter influential factors in selecting the accuracy，nomoral wiring method of secondary windings were analyzed in firstly. And things to be noticed were brought forward when voltage transformer was ploughed into operation and was operating secongly. Finally, two practical methods was offered based on two sides before and after wiring to effectively classify whether secondary circuit wiring was correct. The research results show that the methods illustrate a good prospect of application and extension.
Key words: potential transformer(PT); wiring mode; secondary circuit
