地铁牵引供电系统设计 地铁牵引供电系统设计 The Design of Subway Power Supply System 摘要 牵引供电系统是城市轨道交通系统中最为重要的基础能源设施，其功能是为轨道交通系统中的电力车辆供电，确保轨道交通列车车辆的正常运行。通过对供电方案的比较，**地铁供电系统采用集中供电方式，系统包含电业局地区变电所与轨道交通主变电所之间的输电线路、 统、电力监控系统、接触网系统、杂散电流防护和接地系统、供电车间等组成。轨道交通供电系统的主要功能如下： 接受、分配电能：主变电所的主变压器将110KV高压电变换成20KV中压电、20KV供电网络将电能分配到每一个车站和车辆段牵引变电所 DC1500V接触轨 20kV中压 Abstract Traction power supply system of urban rail transit system is the most important basic energy facilities, its function is providing power for rail transit system, ensure the normal operation of rail transit vehicle. Through the comparison of the power supply scheme, shijiazhuang metro power system uses centralized power supply mode, system contains the transmission lines between area substation and rail traffic main substation, Traction step-down power transmission and distribution network of rail transport power supply system, DC traction supply network and station low voltage distribution network; tractive power supply system is composed of main substation, high-pressure/medium voltage power supply network, tractive power supply system, electric power monitoring and management system, overhead contact system, stray current protection and grounding system, Power supply of 20KV 110 kv high-voltage power supply network in 20KV piezoelectric, energy allocated to each station and maximize the traction substation and step-down in substation. Key words: entralized power supply system traction substation DC1500V contact rail 20kV medium voltage 目 录 第1章 绪论 ..................................................................................................... 4 1.1 供电系统的功能 .................................................................................. 4 1.2 供电系统的构成 .................................................................................. 5 1.3 供电系统电磁兼容 .............................................................................. 6 第2章 电源与主变电所 ...........................................................................
