100％低地板车牵引及辅助变流系统

摘要

介绍我国首列完全自主研制的100％低地板车的牵引及辅助变流系统,包括系统组成及设计、控制功能、系统监控及故障诊断等,分析系统电气及结构设计的原则和机理；研制安装可运行的系统样机,具有轻量化、模块化、人性化的特点,并具备完善的控制和保护功能,可以保障列车的安全可靠运行.%Traction and auxiliary converters are the most important components of 100% tow-floor vehicles. They straighty affect the functions, performance, safety and reliability of the vehicles. This paper introduces the traction and auxiliary converter system for the first domestic 100% tow-floor vehicles, innovated by China with the complete proprietary intellectual property right. The composition and design, control functions, system monitoring and fault diagnosis are described together with the electrical and structure design principles and mechanism. The prototype of the system features lightweight, modularity, humanization and possesses perfect control and protection functions which can ensure the reliable and safe operation of trains.
