摘要/Abstract

摘要： 弓网离线对地铁车辆安全可靠运行带来很大危害。给出了弓网离线的等效过程,得到离线期间地铁车辆弓网系统的等效电路。以某地铁辅助逆变器系统为例进行了离线暂态分析与仿真验证。结果表明,离线引起逆变电路中基波分量大为减小,绝缘栅双极型晶体管IGBT上谐波成分增多,带来耐热、绝缘等方面的隐患,甚至造成逆变器模块损坏,极大地降低了地铁车辆运行的安全性、可靠性。对于IGBT的选型、保护及弓网结构的改进提供了重要参考。

Abstract: Pantograph and catenary off-line brings great harm to the safe and reliable operation of subway vehicles. The equivalent process during off-line and the off-line equivalent circuit of subway vehicles was proposed. Taking a metro vehicles powered auxiliary inverter system as an example, the off-line transient analysis was carried out, and a simulation test was conducted. As shown in the results, the useful signal during off-line greatly reduced in vehicle system and the harmonics of Insulated Gate Bipolar Transistor (IGBT) voltage was greatly increased. The questions about heat-resistant and insulation arose, which caused the inverter module to damage and greatly reduced the metro vehicle operation safety and reliability. Important reference for IGBT selection, protection and pantograph-catenary structure improvement was provided.

Key words: arc, pantograph and catenary off-line, transient process, harmonic analysis, metro auxiliary inverters
