HXD3型机车控制电器柜三项设备自动开关故障冗余设计方案及应用

Redundancy Design Scheme and Application of Automatic Switch Fault for Three Equipment in Control Electric Cabinet of HXD3 Locomotive

针对双HXD3固定重联机车运用中控制电器柜三项设备供电自动开关因使用方式变化产生的行车安全质量问题,提出了一种在控制电器柜上加装三项设备供电冗余自动开关的设计方案,装车应用效果显著。

In view of the problem of driving safety and quality caused by the change of operation mode of three equipment power supply automatic switch of the control electrical cabinet in the operation of double HXD3 fixed double locomotive,this paper proposed a design scheme of adding redundant automatic power supply switch of three equipment to the control electrical cabinet.The effect of loading application is remarkable.
