The invention provides a hydrogen fuel cell hybrid power locomotive charging isolation device, and relates to the technical field of new energy automobile charging devices. The hydrogen fuel cell hybrid power locomotive charging isolation device comprises a power supply module, a control conversion module, a fault detection module, a transformer and a vehicle battery system, the power supply module outputs alternating current and provides electric power needed by charging to the control conversion module, the output end of the power supply module is connected with a locomotive charging interface through a charging wire, and the fault detection module is connected with the transformer. The output end of the locomotive charging port is connected with the input end of the control conversion module, and the control conversion module converts alternating current into direct current suitable for charging. The normal state and the redundant state of the system are monitored through the two safety relays respectively, when one relay detects a fault, the other relay can still keep operating, it is ensured that the power supply is not powered off, and therefore it is ensured that the system can continue to run safely when the fault occurs.

    本发明提供一种氢燃料电池混合动力机车充电隔离装置,涉及新能源汽车充电装置技术领域。该氢燃料电池混合动力机车充电隔离装置,包括电源模块、控制转换模块、故障检测模块、变压器和车辆电池系统,所述电源模块将交流电输出,提供充电所需的电力连接到控制转换模块,所述电源模块输出端通过充电线与机车充电接口连接,所述机车充电口输出端与控制转换模块输入端连接,所述控制转换模块将交流电转换为适合充电的直流电。通过两个安全继电器分别监控系统的常规状态和冗余状态,当一个继电器检测到故障时,另一个继电器仍可保持操作,确保电源不断电,从而保证系统在发生故障时能够继续安全运行。
