The invention provides a traction transmission system of a hybrid power locomotive. The traction transmission system comprises a three-phase rectification module, a plurality of groups of traction inversion modules and an auxiliary inversion module, according to the system, the DC contactor is arranged in front of each traction inversion module and is connected with the intermediate DC loop, so that the faulted traction inversion module can be singly cut off, and the accident of locomotive damage can be avoided; by arranging the discharge resistor in the traction inversion module, energy in the cut traction inversion module can be discharged, so that dangers during overhaul and maintenance are avoided; and through multiplexing of the auxiliary inverter circuit, the power supply requirementof auxiliary electric equipment can be met, and the in-garage charging requirement of the vehicle-mounted storage battery can also be met, so that a special charging circuit or special charging equipment does not need to be arranged.
本发明提供了一种混合动力机车牵引传动系统,其包括三相整流模块、多组牵引逆变模块以及辅助逆变模块。该系统通过在每个牵引逆变模块之前设置直流接触器与中间直流回路连接,可对发生故障的牵引逆变模块进行单个切除,能够避免造成机车机破的事故;通过在牵引逆变模块内部设置放电电阻,能够对被切除的牵引逆变模块内部的能量进行泄放,从而避免检修维护时出现危险;以及通过对辅助逆变电路的复用,既能够满足辅助用电设备的供电要求,又能够满足车载蓄电池的库内充电需求,从而无需设置专门的充电电路或者配备专门的充电设备。
