摘要
本文提出了一种新的电弧动态'黑箱'模型。其特点是从电弧的外部特性和静态特性来建立方程。利用此模型,分析了中性点不接地系统单相电弧性接地所引起的过电压。实验及计算表明,此模型具有良好的适用性。
This paper described a 'black box' mode of dynamic arc.Its feature is that equation was established on the basis of external and static characteristics of arc.The overvoltage due to one-phase arc grounded faults in the power supply system with neutral point not earthed was investigated by using this model. The results of computation and experiment indicated that the model was quite suitable.
