短路电流的研究与分析

Study and Analysis on the Short-circuit Current

以某采区供电系统中的系统电抗值、高压电缆的阻抗值、变压器的阻抗值、低压电缆的阻抗值、短路回路中一相的总电阻和总电抗及短路电流值的计算为例,研究、分析了系统电源电抗对短路电流的影响。

Taking the calculation of system's resistance and reactance value, high-voltage cable's resistance and reactance value, transformer's resistance and reactance value, low-voltage cable's resistance and reactance value, short-circuit's one-phase total resistance and reactance value, and the short-circuit current value of the power-supply system of a certain mining area as the example, this paper studies and analyzes on the influence of the source reactance on the short-circuit current.
