Abstract:Research purposes: The position of the electric phase splitting is one of the key factors forensuring safe and reliable operation of train on passenger dedicated line. This papermainly researches the influence of the signal system and train control system on locating the electric phase splitting, and presents the calculation principles and analysis model for checking calculation ofauto-passing phase splitting by the CTCS -3 -based EMU for providing the reference to survey and design of passenger dedicated line.
Research conclusions: According to the calculation principles, for the track where only the single -unit EMU composed of 8 coaches runs, it is suggested that the minimum distance between signal and electric phase splitting should be not less than 217. 5meters. For the track where the twin -unit EMU composed of 16 coaches runs with speed of 200 km /h, the minimum distance between signal and electric phase splitting should be not less than 431. 05 meters, and when the distance is notup to 431. 05 meters, the average start gradient should be no more than 15. 5‰.
