摘　　要：在复杂铁路线路或枢纽地区,牵引网有时采用T接方式。通过对T接牵引网回路的研究,提出了T接全并联AT供电牵引故障时,采用横联电流比原理计算故障距离的修正方法。In complex railway lines or hub areas,the"T-connection"mode is sometimes adopted for traction network.Based on the study of"T-connection"traction network circuit,a correction method of calculating the fault distance by using the principle of transverse current ratio is put forward for fault condition of"T-connection"full parallel AT power supply traction.

关 键 词：T接牵引网 故障测距 横联电流比 全并联AT供电
