摘要
轨道交通的供电系统包括高、中、低压交流供电系统、直流供电系统以及电力集中监控系统(SCADA)等。叙述了轨道交通用直流供电系统的基本原理,简要介绍了直流供电系统的关键电器设备,如整流器、直流快速断路器、直流开关柜等。
The power supply system for mass transit railway consists of HV,MV,LV AC power distribution systems, DC power distribution systems and SCADA telecontrol systems etc. This paper describes the basic principle of DC power distribution systems for mass transit railway and briefly introduces the key apparatus of DC power distribution systems.
