The invention discloses a method for suppressing arcing overvoltage and neutral section passing VCB operation overvoltage, and the method specifically comprises the steps: transmitting a pre-preparation signal to a vehicle-mounted ATP control system through an ATP automatic neutral section passing system operation logic before a train passes through an insulation joint or a neutral section; the train sends out enabling signals of different working conditions according to corresponding signals and starts to receive an operation position signal sent by a ground sensor at the next position at the same time, and after the operation position signal is received, the train selects a proper phase to replace the grounding mode of the train according to running information such as the train speed read by the ATP system; and after the train passes through the insulation joint or the electric split-phase interval, the original grounding mode is recovered after the ground opening signal is received, and the train recovers normal operation. According to the invention, the grounding system is effectively protected from being affected by overcurrent impact under different working conditions, the maintenance cost is reduced, and the applicability is high.
本发明公开了一种燃弧过电压与过分相VCB操作过电压抑制方法,具体为:依托ATP自动过分相系统操作逻辑,在列车过绝缘节或过分相前,向车载ATP控制系统发送预准备信号,列车根据相应信号发出不同工况的使能信号并同时开始接收下一位置地面传感器所发送的操作位置信号,接收到操作位置信号后列车根据ATP系统读取到的列车速度等运行信息选取合适的相位更换列车的接地方式,在列车通过绝缘节或电分相区间后在接收到地面分闸信号后恢复原有接地方式,列车恢复正常运行。本发明有效地保护了接地系统在不同工况时受到过电流冲击的影响,减小了维护成本,适用性强。
