关于地铁车辆主电路保护配置的研究

Analysis of Main Circuit Protection Configuration on Metro Vehicle

地铁车辆在运行过程中会遭受过电压、过电流带来的危害,这就要求在车辆上对这些危害设置相应的保护。本文对各保护装置的参数选择及各装置之间的匹配进行分析,以确保合理配置各保护装置,使危害降低到最低点。

Vehicle can be subjected to the harm of over voltage, over current during the operation. The vehicle must be settled corresponding protection to these hazards. This paper analyzes the selection of protection device and the matching between each device, in order to maximally reduce its harm.
