The invention relates to the technical field of railway vehicle charging, in particular to a charging system and method for a railway vehicle, and the system comprises a pre-charging circuit, a charger single-machine module, an output power distribution circuit, a monitoring unit, and an electric leakage detector. The charger single-machine module converts 380V alternating-current power supply voltage into isolated DC110V to supply power to the output power distribution circuit, the power distribution circuit comprises a storage battery and power supply buses BN1, BN2 and BD3, and the electric leakage detector is used for detecting insulation conditions of the power supply buses BN1, BN2 and BD3 and transmitting detection results to a railway vehicle network through the monitoring unit. According to the invention, efficient conversion from 380V alternating current to DC110V direct current is realized, the electric energy conversion efficiency is remarkably improved, and the energy loss is reduced.
本发明涉及轨道车辆充电技术领域,尤其涉及一种用于轨道车辆的充电系统及方法,包括预充电电路、充电机单机模块、输出配电电路、监控单元和漏电检测仪,交流供电电压经预充电电路进入到充电机单机模块,充电机单机模块将380V的交流供电电压转换为隔离的DC110V,为输出配电电路供电,配电电路供电包括蓄电池和供电母线BN1、BN2和BD3,漏电检测仪用于检测供电母线BN1、BN2和BD3的绝缘情况并将检测结果通过监控单元传输至轨道车辆网络。本发明实现了从380V交流到DC110V直流的高效转换,显著提高了电能转换效率,减少了能量损耗。
