应用电磁场数值计算法分析和计算了新型电抗器—干式半心电抗器的谐波 :用场路耦合法建立其数值计算模型 ,解得正弦电压激励下通过电抗器的非正弦周期电流 ;再用付氏变换展开并计算分析谐波计算结果表明铁心材料、尺寸和激励电压均会影响谐波含量。
In this paper the harmonic of a new kind of reactor-dry type half-iron-core reactor is analyzed and calculated with electromagnetic field numerical calculation method. First, the numerical calculation model of the reactor is set up using field circuit coupling method. The non-sinusoidal periodic current through the reactor is obtained under the sinusoidal voltage source. Then, with Fourier Transform the current is decomposed to different frequency components. Last, the harmonic of the reactor is analyzed and calculated.
