客运专线长编动车组自动过分相问题探析

摘要

In view of the recent twice abnormal on-off VCB during the joint debugging and commissioning on the passenger dedicated line in process of automatically passing neutral section, analysis of automatic splitting phase device is conducted with data recorded by on-board device and ground equipment to find out the causes of the abnormality. It is concluded that the setting-up or adjustment of the position of the ground magnetic sensor or modifying the parameters of the train control onboard equipment software can solve the problem.%针对近期开通的客运专线在联调联试过程中发现自动过分相存在两次断合VCB(真空断路器)的异常问题，通过对车载设备的记录数据及地面自动过分相装置的设置情况进行分析，找到两次断合VCB异常问题的原因，通过调整地面磁感应器的设置位置或修改列控车载设备软件参数可解决该异常问题。
