摘要
随着城市轨道交通车辆运行里程的增加,车辆电气部件的故障率随之呈现增长态势,许多车辆相继进入了架修或大修阶段。辅助逆变系统是车辆电气部件必不可少的部分,其核心部件就是辅助逆变器。从辅助逆变器的工作原理出发,从科学论证与上机验证的角度介绍了城市轨道交通车辆辅助逆变器离线式诊断系统的设计原理,着重阐述了直流供电系统模块、预充电和主电路保护模块、负载模块、信号转换模式、控制系统模块的设计方案,并对该诊断系统的设计进行仿真。该系统经实践验证整体效果良好,正逐步应用到辅助逆变器的故障修和架修、大修中。
With the rapid increase of urban rail transit operation mileage,the growth trend of vehicle electric component fault rate also appeared,many rail transit vehicles have entered the stage of unwheeling repair or overhaul.The auxiliary inverter system is a major part in metro vehicle electric equipment,and the key component of the system is auxiliary inverter.Based on its working principle,the design of auxiliary inverter off-line diagnose system for urban rail transit vehicles is introduced from the angles of scientific demonstration and computer verification The design schemes of DC power supply system module,load module,signal conversion mode and control system module are emphasized.Finally,the off-line diagnose system is simulated and the result shows that the system has good performance,and is currently applied to the fault repair,unwheeling repair and overhaul of auxiliary inverter.
