| 摘 要： | 依据两表法测量三相电功率的原理，对三相线路中各线电压和电流之间的关系进行了分析，推导出数种等效接线方法。经对比实验证明，完全可以正确反映所测对象的实际三相功率值。进而针对煤矿井下高压开关柜布线特点，应用等效接线法简单而实用。

| Abstract: | Based on the principle for three phase electric power measuring with the two unit method, several equivalent measuring methods were derived in this paper according to the analyses of relation between voltages and currents in three phase electric circuits. A contrast test was designed to give the difference between the standard measuring method and the equivalent measuring methods. The results show that the equivalent measuring methods are accurate and especially simple in the situation of coal mine control device. |
