摘要
高压输电线路中短路电流零点延迟会对高压断路器的开断造成影响。通过简化电路的仿真计算,得出在高压输电线路中短路电流延迟零点的条件,其中包括电网条件和短路条件,并分析在高压线路中具有这些条件的现实性。分析结果验证了该现象存在的现实性,但概率很小。
With the calculation of simplified electric circuit, this paper obtained the conditions of short circuit current zero delayed, electric networks conditions and short circuit conditions. The possibility of short circuit current zero delayed occurred in high voltage transmission lines was analyzed. The result shows the probability is very low.
