The invention discloses a pantograph rising fault positioning method of a pantograph, a controller and a train, and relates to the field of fault detection.The pantograph rising fault positioning method comprises the steps that in the process of sending a pantograph rising instruction to a pantograph rising relay through a pantograph rising train line to rise the pantograph selected by a driver or automatically selected pantograph, the pantograph rising instruction is sent to the pantograph rising relay within the first preset time of sending the pantograph rising instruction; the pantograph rising train line, the pantograph rising relay and the pantograph rising holding relay are sequentially powered on, the fault position is determined according to whether the pantograph rising train line, the pantograph rising relay and the pantograph rising holding relay are powered on or not, and it is judged that the pantograph rises normally only when the pantograph needs to rise in place and the traction system has network voltage within the second preset time when the instruction is sent. The fault range is narrowed in sequence according to the connection relationship, and the fault position is finally determined, so that the maintenance personnel can maintain more conveniently.
本发明公开了一种受电弓的升弓故障定位方法、控制器及列车,涉及故障检测领域,包括通过升弓列车线向升弓继电器发送升弓指令以升起驾驶员选择的受电弓或自动选择的受电弓的过程中,发送升弓指令的第一预设时间内,升弓列车线、升弓继电器及升弓保持继电器依次得电,根据三者是否得电确定故障位置,发送指令的第二预设时间内受电弓应升弓到位且牵引系统有网压,才算作受电弓升弓正常。根据连接关系依次缩小故障范围,最终确定故障的位置,使得运维人员检修更加方便。
