摘要
为了抑制谐波的危害,采取一种有效的措施,在电容器回路中串联电抗器。这种方法表明,串联电抗器的电抗率不同,抑制谐波的效果也截然不同。分析了电容器缺台运行电容器部分击穿运行对串联电抗器谐波抑制的影响。同时介绍了并联电容器及串联电抗器额定电压选择应匹配才能有效抑制谐波的情况。
For suppressing the danger of harmonics, the effective measure adopted is series reactor in capacitor circuit. It is shown by this method that the effect of harmonic suppression is different due to different reactance ratio of series reactor. The influence of operation, in lacks unit and capacitor partial breakdown, on harmonic suppression of series reactor are analyzed and, at the same time, it is introduced in this paper that matching choice of rated voltage of shunt capacitor and series reactor can effectively control harmonics.
