Research on Electromagnetic Interference Protection for On-Board Signal Equipment of Urban Railway
The electromagnetic environment of AC traction is extremely complex and the operat-ing conditions are very harsh.The frequent on-board signal failures caused by electromagnetic interference pose potential safety hazards for the train.The paper conducts an study on the prob-lem of electromagnetic interference faced by onboard signaling equipment for AC traction trains,establishing principles of signal location for such equipment as well as a model of electro-magnetic interference sources.By analyzing the results of signal failures caused by electromag-netic interference in an AC traction system,we explore the characteristics of electromagnetic in-terference protection from the perspective of onboard signal location principles.Ultimately,the paper propose a practical solution aimed at resolving technical difficulties that threaten the safe and stable operation of the signaling system.
