研究目的:电分相设置位置是保证列车运营安全可靠的关键因素之一。本文重点研究信号系统、列控系统对供电系统中的接触网电分相设置位置的影响,提出了基于CTCS-3级列控系统动车组列车自动过分相的检算原则和模型;为客运专线勘察设计提供一些有价值的研究成果。研究结论:根据检算原则,建议仅开行单组(8辆编组)动车组的线路,电分相距离信号停车牌的最短距离应保证不小于217.05 m;开行重联(16辆编组)动车组的线路,应保证不小于431.05 m;开行200 km/h重联动车组的线路,当无法满足431.05 m要求时,此范围内列车平均起动坡度不应大于15.5‰。
Research purposes: Setting the position of the split phase is one of the key factors to ensure the safe and reliable operation of the train. This paper focuses on the signal system, train control system on the power supply system in the contact network phase-split location, proposed based on CTCS-3 train control system EMU train automatic over-phase detection principle and model; for the passenger dedicated line Survey design provides some valuable research results. Research conclusions: According to the principle of checking, it is suggested that only the lines of a single group (8 marshalling) EMUs be opened and the shortest distance from the signal stop sign should be no less than 217.05 m; the reopening (16 marshalling) EMUs Of the line should be no less than 431.05 m. When the line with 200 km / h heavy reopening line is started, the average starting gradient of the train in this range should not be more than 15.5 ‰ when it can not meet the requirement of 431.05 m.
