摘要
郑西客运专线陕西省境内四个牵引变电所采用330kV等级电压进线,这在我国电气化史上还是第一次,为适应这一变化,牵引变电所的设计应相应有所变化,牵引变压器采用双重化保护配置。母差保护、330kV/10kV电力变压器保护均采用双重化配置。
Zhengzhou to Xian passengers line in Shanxi Province adopted the territory of the four traction substations. 330kV voltage levels into line in the electrification history of our country is the first time, in order to adapt to this change, the design of traction substations shall be subject to change, traction transformer configuration of the use of double protection. Busbar protection, 330kV/10kV power transformer protection using double configuration.
