The invention discloses a train electric leakage recovery method, device and equipment and a medium, and relates to the technical field of rail transit, in particular to the technical field of train power supply. The method comprises the following steps: carrying out electric leakage detection on a train to determine electric leakage nodes; if the electric leakage node is a track side node, performing circuit breaking processing on the track side node, and controlling the battery module to enter a power supply state; if the electric leakage node is the train side node, detecting the acquisition voltage of the train, and controlling the battery module to enter a power supply state when the acquisition voltage is smaller than a preset threshold value; the collected voltage is rail side voltage collected by a traction inverter of the train. By the adoption of the method, when the train is powered on (that is, the train is in the running state), electric leakage detection can be conducted on the train, the specific position (that is, the electric leakage node) where electric leakage happens is determined, normal nodes except the electric leakage node are powered in time through the battery module, it is guaranteed that the train runs without interruption, and convenience is provided for operation of the train.

    本申请公开了列车漏电恢复方法、装置、设备和介质,涉及轨道交通技术领域,具体涉及列车供电技术领域。该方法包括:对列车进行漏电检测,确定漏电节点;若漏电节点为轨道侧节点,则进行对轨道侧节点进行断路处理,并控制电池模组进入供电状态;若漏电节点为列车侧节点,则检测列车的采集电压,并在采集电压小于预设阈值时控制电池模组进入供电状态;采集电压为列车的牵引逆变器采集到的轨道侧电压。采用本申请的方法,可以在列车上电(即列车处于运行状态下)时,对列车进行漏电检测,确定发生漏电的具体位置(即漏电节点),并通过电池模组对漏电节点以外的正常节点及时进行供电,保障列车不中断运行,为列车的运营提供了便利。
