基于查表法的电能计量装置错接线判断方法

A Electrical Energy Metering Mechanism Wrong Wiring Judgment Method based on the Table

基于电压、电流和相位角等原始电参数,通过电压相序判断、线电压归位、相角转换、相电流定位等判断分析表,提出了一种简便直观的错误接线判断方法,可对三相三线常见的错误接线进行快速准确判断。此过程不需要绘制向量图,只需根据实测数据进行逐步查表就可得出结论。大大简化了用电检查人员进行错接线判断分析的难度,并且该算法可方便地使用计算机程序来完成,以实现错接线判断分析的全自动化。

This angle based on the voltage, the electric current, the phase angle and so on primitive electrical parameter, through the voltage foreword judgment, the line vohage homing, the phase angle transformation, the judgment analytical tables and so on interphase current localization, proposed one simple direct-viewing false wiring judgment method. It can carry on the fast accurate judgment to the three phase three common false wirings. This process does not need to draw up the vector diagram, only need to look-up the table. It simplified the wrong wiring judgment analysis, and this algorithm might use the computer program to complete conveniently, make the wrong wiring judgment analysis entire automation.
