The invention provides an urban rail transit traction power supply system and a substation. The traction power supply system is used for suburb urban rails and comprises a first rectifier unit and a second rectifier unit, wherein the first rectifier unit and the second rectifier unit are independently installed in a unit shell with the insulation grade of 3kV,; a 3000V power supply is output whenthe first rectifier unit and the second rectifier unit operate in series through an isolating switch; and a 1500V power supply is output during parallel operation. The system has the advantages of being low in cost, high in power supply capacity, long in power supply distance and small in influence of electrical insulation on civil engineering.
本发明提供一种城市轨道交通牵引供电系统及变电所,该牵引供电系统用于市郊城市轨道,所述牵引供电系统包括:第一整流机组、第二整流机组,第一整流机组和第二整流机组独立安装在绝缘等级为3kV的机组外壳内,通过隔离开关串联运行时输出3000V电源;并联运行时输出1500V电源。上述系统具有成本低,且供电能力强、供电距离长、电气绝缘对土建影响较小的优点。
