摘　　要：通过对HXD3型机车辅助变流器(APU)电流极限导致无牵引电流典型故障的分析,判断导致故障的原因,提出优化APU现有冗余系统控制逻辑的措施,一定程度上可以防止该故障发生.By analyzing the typical faults of traction without current caused by the current limit of the HXD3 locomotive auxiliary converter(APU),we figured out the fault causes and proposed the optimization measures to the control logic of the existing APU redundant system,which to some extent can prevent the fault occurrence.

关 键 词：HXD3型电力机车 APU 控制逻辑 电流极限
