| 摘 要： | 供电牵引网运行方式多种多样,在常规的单线、复线供电方式中,传统的电抗法、电流比法在实际应用中均能满足要求。对于全并联直接供电牵引网短路故障,采用两相对称分量法,分析电路特征,得到短路阻抗表达式。根据阻抗表达式绘出电抗距离曲线图,证明全并联直接供电牵引网短路时,故障点仍然可以采用电抗查表法进行定位。

| Abstract: | The types of power traction system are various. In the normal type of single line or double line system, traditional methods, like reactance or current-ratio method, are satisfied in the actual application. For the direct power traction systems with full parallel connection, the characteristics of short-circuit impedance is analyzed with method of two symmetrical phases, and the expression is acquired. Based on the graph of the reactance-distance, the scheme of reactance-distance can be used in fault location of direct power traction system with full parallel connection. |
