    摘 要:研究了品質(zhì)因數(shù)Q 值對電容器投入配網(wǎng)時的沖擊涌流的影響,對單相晶閘管投入電容器電路進行了分析,通過建立數(shù)學模型并仿真可知,沖擊涌流與線路參數(shù)電阻R 、電感L 和電容C 的值有關,線路參數(shù)綜合作用的結(jié)果是品質(zhì)因數(shù)Q 值越大,沖擊電流也越大。在實際應用中,應該調(diào)節(jié)線路參數(shù)使品質(zhì)因數(shù)盡可能小來提升設備的性能。
    關鍵詞:電容器;單相晶閘管;品質(zhì)因數(shù)Q 值;沖擊涌流;線路參數(shù)

    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
