| 摘 要： | 从裂心式磁控电抗器的结构与电路入手，分析了直流偏磁实现的原理，推导出各种工作状态下各支路的电流表达式，继而得到柱电流随直流偏磁电流改变的波形，最后通过实验波形，验证了理论分析的正确性：直流偏磁逐渐增大，铁心趋于饱和，相电流波形越接近正弦波，谐波含量越来越小。 |

| Abstract: | By giving the structure and circuit of crack core type magnetic controlled reactor, formation mechanism of DC bias is analyzed. The current expression of each branch during different operation status are derived, and the waveform of column current changing with the DC magnetic bias current is acquired. By comparing with the tested waveform results, the accuracy of the theoretical analysis is confirmed that when the DC magnetic bias current increases gradually, the iron core tends to saturated, the interphase current profile is close to sine wave, and the harmonic content is getting smaller. |
