采用相间磁平衡技术，利用电感来平衡相间的电压矢量差，通过DSP控制单元对三相电信号采集处理并选择适当电压补偿档位，从而使相间电压接近相等，减少了中线电流和无功功率，达到节电目的，可以将线路的功率因数提高到0.92以上，谐波失真减少80%，滤除对用电设备的尖峰干扰，节能效果可达5~20%，扩大了配电变压器的承载能力。%In this paper, three-phase magnetic balance technology was adopted, the inductance is used to balance the difference of voltage vector,the DSP control unit sample and the three-phase electrical signal is processed and the ap-propriate voltage compensation is selected. To make sure that three-phase voltage is close to equal, the line current and reactive power are reduced. The purpose of energy conservation are achieved, the power factor of line can be in-creased to above 0.92, harmonic distortion is reduced 80%, rushing disturbance of electrical equipment is filtered out, energy conservation effect is up to 5% ~ 20%.The carrying capacity of the distribution transformer is expanded.
