摘　　要：综合车辆过压故障记录及第三轨供电断轨区情况后,对北京地铁房山线车辆过压故障原因进行分析。提出了改变母线贯穿形式、优化牵引系统控制功能、改善ATO(列车自动运行)模式下的通过状态和改变车辆折返时的进出方式等四种解决方案。从运营角度对四种解决方案的特点进行了论述。确定了优化牵引系统控制功能的方式更符合现场条件,并通过该方案的实施消除了运营隐患。Based on the vehicle overvoltage fault records and third rail power supply of the track breakage area,the causes of the overvoltage fault of the vehicles on Beijing metro Fangshan Line are analyzed.Four solutions are proposed,including changing the bus penetration form,optimizing the control function of the traction system,improving the passing state under ATO(automatic train operation)mode,and changing the access mode when the vehicles turn back.From the perspective of operation,the characteristics of the four solutions schemes are discussed.It is concluded that the measure of optimizing traction system control function suits the site condition better,and hidden dangers of operation are eliminated through implemention of the scheme.
