地铁35 kV环网数字通信电流保护测试方法

Test Method For Digital Communication Current Protection of 35 kV Ring Network in Subway

在地铁中,35 kV环网线路是地铁供电系统的主要电源通路,对整个地铁系统有着十分重要的作用.随着我国社会经济的不断发展和城市化建设的不断深入,城市建设中地铁建设也在不断完善和加强.随着地铁线网规划的逐渐完善,使得线网共享主变电所以及中压环网分区供电使用方法逐渐普及,也是在此基础上,数字通信电流保护得到了重视和发展,因其特殊性和科学性,对其展开研究.

my country’s subway development has become one of the most advanced arrays in the world,and its development is inseparable from my country’s vigorous research and capital investment in subway.In the subway,the 35 kV ring network line is the main power path of the subway power supply system,which plays a very important role for the entire subway system.With the continuous development of my country’s social economy and the deepening of urbanization construction,the subway construction in urban construction is also constantly improved and strengthened.With the gradual improvement of the subway’s existing network planning,the use of the existing network to share the main substation and the medium-voltage ring network zoning power supply is becoming common.It is also on this basis that digital communication current protection has been paid attention to and developed because of its special Sexuality and scientifi city,a series of research can be carried out on it,by taking a series of tests and research and analysis on its principles.
