摘　　要：通过对三相对称节能灯负载中线电流波形测试分析,指出两种负载情况下中线电流不同的原因。通过对相电流及中线电流的计算,给出了二者的关系式,为确定选择中线提供了理论依据。The reason, why in two cases the central wire current is different from the other under different load, is given by checking and analysis of the wave shape of loaded central wire current of three phase symmetry fluorescent lamp. The relation formula is given by calculating the phase current and central wire current, thus the motivation of central wire choice is offered.
