相序检测电路的相量分析

Phasor Analysis of Electric Circuit Used for Phase－sequence Detection

运用基尔霍夫定律和正弦交流电的符号法对相序检测电路中灯泡端电压与相序的关系进行了理论推导和定量分析，以此为依据说明相序的判断方法。

The relations between the terminal voltage of the bulb and phase－sequencc in phase－sequence de－tection electric circuit are studied in theory and quantitative analysis by using Kirchoff's laws and sine－type al－ternating current symbolic method. The phase－sequence detection method is given.
