网侧过电流测量故障在CRH1型动车组运行过程中会引起受电弓自动降弓,对动车组运行稳定意义影响重大。通过对网侧过电流测量故障分析,提出措施以期降低或者避免故障的发生,确保动车组的稳定运行。
Over-current measurement fault on the grid side will cause the pantograph to bow automatically during the operation of the CRH1 type EMU, which has a significant impact on the stable operation of the EMU. Through analyzing the fault of over-current measurement on the grid side, measures are put forward in order to reduce or avoid the occurrence of faults and ensure the stable operation of EMUs.
