三相负载星形连接实验数据与分析

本文研究了"电工电子技术"课程设计实验中四种不对称三相负载星形连接的实验数据,重点分析了三相负载星形连接的实验电路中有中线时的相电流和中线电流,以及无中线时的相电压和中性点位移电压,并将理论值与实验值进行比较可知两者比较接近,指出了星形连接时中线的作用以及中性点位移对三相负载的影响。

Y-connected Three-phase Loads Experimental Date and Analysis

This paper studies the experimental date of four asymmetrical Y-connected three-phase loads in the de- sign experiment of Electrical and Electronic Technology course. The key analysis of this paper includes both the phase current and the neutral current with the neutral line and the phase voltage and the neutral point displacement voltage without the neutral line in the experimental circuits with Y-connection three-phase loads. The theoretical and the experimental data are compared and showed that the two are excellent agreement. The role of the neutral line with Y-connection configuration and the impact of the neutral point displacement to the three-phase loads are also analyzed.
