地铁辅助逆变器原理及故障分析

随着先进技术的迅速发展,地铁车辆的整体性能得到了极大的提高。它给人们的日常生活带来了极大的便利。然而,地铁辅助逆变器是车辆的重要组成部分,其结构复杂且集成度高。地铁辅助逆变器是辅助系统(地铁线路的核心部分,它为除列车牵引以外的一些电气设备供电,包括空调系统、风扇系统和各种控制回路)。因此,快速准确的诊断方法对于地铁辅助逆变器至关重要。

With the rapid development of advanced technology, the overall performance of metro vehicles has been greatly im-proved. It brings great convenience to people＇s daily life. However, the metro auxiliary inverter is an important part of the vehicle,and its structure is complex and highly integrated. Metro auxiliary inverter is the auxiliary system （the core part of the subway line,which supplies power to some electrical equipment except train traction, including air-conditioning system, fan system and variouscontrol loops）. Therefore, the fast and accurate diagnosis method is very important for the auxiliary inverter of metro.
