摘要
传统的干式空心电抗器在使用时需要用电阻来调节阻抗值。一种新型干式空心电抗器通过电抗器线圈与阻尼环之间的电磁感应来调谐电抗器的阻抗,达到所需的品质因数值。针对此种新型空心电抗器,提出了一种场路结合的品质因数计算方法。与实测结果进行比较,计算结果证实了方法的准确性。
Traditional dry-type hollow reactor has to work with a resistance to balance the impedance. There is a new kind of dry-type hollow reactor which can regulate impedance by electromagnetic induction between the reactance coil and damping ring to reach an ideal quality factor. Based on field and circuit theory, a method to calculate the impedance and the quality factor of this hollow reactor is proposed in the paper. In comparing to the measured values, the calculation results show that the method has high accuracy.
