摘要
对三相非线性负载(以彩电为负载)时的中线电流波形进行了测试,对此中线电流波形用正弦脉冲函数表示求出了中线电流的有效值,给出了中线电流与相电流的关系式,为非线性负载下供电线路的设计提供了参考依据。
The waveform of load middle current in three-phase symmetry colour TV is tested and expressed with sine impulse function, in this way the virtual value of current in middle wire is found and a relational expression between current in middle wire and in phase conductor is given; therefore the theoretical basis is provided for design of power supply circuit with nonlinear load.
