摘要
根据三相短路电流中带有直流分量时的开断过程,提出了分析和计算燃弧时间差的方法,据此求出了中性点接地与不接地系统的短路电流中带有直流分量时,燃弧时间差的分布规律.本文也列出了开断电流波形与电弧能量的关系.
A method is presented to calculate the arcing time difference in in-terrruption of three phase short-circuit currents. Based on this, the distribution laws of the arcing time difference are found for short-circuit currents containing DC component in neutral earthed or isolated system.
