The embodiment of the invention provides an overcurrent fault detection system and method, and a rail vehicle, and the overcurrent fault detection system comprises a first detection unit, a second detection unit, a third detection unit, and a control unit. The first detection unit is located on a main circuit where the first pantograph is located and arranged between the first pantograph and a first traction transformer. The second detection unit is located on a main circuit where a second pantograph is located and is arranged between the second pantograph and a second traction transformer; the third detection unit is arranged on a common branch of a branch from the first pantograph to the second traction transformer and a branch from the second pantograph to the first traction transformer; the third detection unit is connected with a third traction transformer; and the control unit is used for identifying the pantograph in a pantograph rising state, positioning a fault area accordingto the collected overcurrent signals of the first detection unit, the second detection unit and the third detection unit, and processing the fault. The operation safety and reliability of the train are improved.

    本发明实施例提供一种过流故障检测系统、方法及轨道车辆,其中,过流故障检测系统,包括:第一检测单元、第二检测单元、第三检测单元和控制单元;第一检测单元位于第一受电弓所在的干路上,设置于第一受电弓和第一牵引变压器之间;第二检测单元位于第二受电弓所在的干路上,设置于第二受电弓和第二牵引变压器之间;第三检测单元设置于从第一受电弓至第二牵引变压器的支路和从第二受电弓至第一牵引变压器的支路的公共支路上;第三检测单元连接第三牵引变压器;控制单元用于识别处于升弓状态的受电弓,根据采集到的第一检测单元、第二检测单元和第三检测单元过电流信号,定位故障区域,对故障进行处理。提高列车的运行安全性、可靠性。
