| 摘 要： | 目前在中低压电网中使用比较多的消弧线圈是自动调谐调匝式消弧线圈,这种消弧线圈采取的是预调节方案,即在电网正常运行时调节消弧线圈档位使消弧线圈的电抗等于电网的容抗,为抑制全调谐状态下的串联谐振过电压,一般采取并联或串联阻尼电阻的方法,但如何选取阻尼电阻是比较困难的,该文详细分析了自动调谐调匝式消弧线圈阻尼电阻的选取原则,具有一定的实用价值。

| Abstract: | The automatic-tuning multi-tap arc-suppression coil is used widely in middle and low voltage power system now. The advanced tuning scheme is used in this kind of multi-tap arc-suppression coil. That is to say the reactance of the arc-suppression coil equals the capacitive reactance of the power system in normal power system. In order to control the series resonance over-voltage, the damping resistance is employed. But it is difficult to select damping resistance. This paper analyses the selecting principle of damping resistance for the automatic-tuning multi-tap arc-suppression coil in detail. The method has some practical value. |
