资料介绍

全自动驾驶列车采用复位机构来模拟人工复位断路器的动作,在检测到断路器跳闸后尝试再次投入。依据列车直流供电回路中的负载特性,设计了一种具有漏电流检测及电源远程复位功能的电路,对供电回路的状态进行实时监控,及时判断接地、短路等故障回路,对故障回路进行远程复位,实现电源级重启。减少了电路中因过流发热引起的隐患,从而提高无人值守的全自动驾驶列车供电回路的可靠性及可用性。

The fully automatic driving train uses a reset mechanism to simulate the action of manual reset circuit breaker,and attempts to re-enter after detecting that the circuit breaker tripped.According to the load characteristics(such as coils,power modules,etc.)in the train DC power supply loop,a kind of circuit with leakage current detection and power remote reset function is designed to monitor the status of the power supply unit circuit in real time and determine the fault loop of grounding or short circuit in time.Power level circuit restart can be achieved after remotely resetting the fault loop.It reduces the hidden problems caused by over-current heating in the circuit,thereby improving the reliability and availability of the unmanned fully-automatic driving train power supply loop.
