    摘 要:研究了品质因数Q 值对电容器投入配网时的冲击涌流的影响,对单相晶闸管投入电容器电路进行了分析,通过建立数学模型并仿真可知,冲击涌流与线路参数电阻R 、电感L 和电容C 的值有关,线路参数综合作用的结果是品质因数Q 值越大,冲击电流也越大。在实际应用中,应该调节线路参数使品质因数尽可能小来提升设备的性能。

    Abstract: This paper researched on the impact of quality factor Q value on the impact inrush current during the capacitors switching to the distribution network and analyzed the single-phase thyristor switching capacitor circuit. The mathematical model was established. The simulated results show that the impact inrush current is related to the line parameters such as resistance, inductance and capacitance values. The synthetic action of line parameters is that the higher the quality factor Q value is, the higher the switching current will be. In practical applications, the line parameters should be adjusted to let the quality factor Q value as small as possible to improve the performance of the equipment.
    Key words: capacitor; single-phase thyristor; quality factor Q value; impact inrush current; line parameters
