Abstract
On the traveling route of the EMU,there are some sections without track circuits,such as the location of tread detection equipment near the entrance of an EMU station and the train lines used for storing trains in the passenger car servicing depot.Due to the absence of track circuits,it is not possible to monitor the connection status of rail lines and rail resistance to ground.Under unfavorable conditions,the high harmonic signal in unbalanced traction current disturbs the train-borne equipment of EMU and even causes the train to stop.Through field test and data analysis,this paper determines the reasons behind two cases of EMU stopping,and puts forward a solution to optimize the traction backflow and reduce harmonic interference.关键词
