The invention provides a train overvoltage protection method, an overvoltage protection system and a train, which can be applied to the technical field of electrified rail transit. The method comprises the steps that split-phase area information and running state information of at least one second train are obtained, the split-phase area information is sent by a ground control center or a ground transponder, and the first train and the second train run under the same power supply arm; the on-off time of a vacuum circuit breaker is predicted according to the split-phase region information and the running state information, and a traction transformer of the first train is connected with a power supply arm through current input equipment provided with the vacuum circuit breaker; under the condition that the first train runs to the on-off time, the vacuum circuit breaker is controlled to be disconnected with the traction transformer; and controlling the vacuum circuit breaker to be connected with the grid-side overvoltage protection module so as to suppress the overvoltage by using the grid-side overvoltage protection module.

    本公开提供了一种列车过电压防护方法、过电压防护系统及列车,可以应用于电气化轨道交通技术领域。该方法包括获取分相区信息和至少一个第二列车的运行状态信息,其中,分相区信息是由地面控制中心或地面应答器发送的,第一列车和第二列车在同一供电臂下运行;根据分相区信息和运行状态信息,预测真空断路器的通断时间,其中,第一列车的牵引变压器通过安装有真空断路器的电流输入设备与供电臂连接;在第一列车运行至通断时间的情况下,控制真空断路器断开与牵引变压器的连接;控制真空断路器与网侧过电压防护模块连接,以利用网侧过电压防护模块对过电压进行抑制。
