摘　　要：结合工程实例,针对小运量的单线电气化铁路分析了采用单相变压器时电力系统的负序影响,并与三相V/v接线牵引变压器进行比较。结论表明,对于单线电气化铁路而言,单相牵引变压器负序影响并不一定比其他类型的牵引变压器大,在选择牵引变压器接线形式时,应结合线路负荷特点,有针对性地选择。In this paper, focusing on small volume single line electrified railway in single-phase transformer to electric power system negative sequence influence are analyzed, and the three-phase V/v connection traction transformer are compared. The conclusion shows that, for single line electrified railway, traction transformer negative sequence influence is not necessarily more than other types of traction transformer, in the selection of traction transformer connection form, should be combined with the line load characteristics, targeted selection
