摘要:
城市轨道交通中压网络是主变电所、牵引供电系统和动力照明供电系统相互连接的重要环节，同时也制约着主变电所位置及数量的确定。运营及在建线路环网分区的划分经历了“短分区”—“长分区”—“短分区”的过程。阐述了不同分区的几种保护方式的原理，从保护可靠性、供电系统维护等方面进行了分析；同时结合实际工程应用实例，对中压环网的分区形式进行比较，通过潮流计、保护方式选择及电缆投资对分区划分进行分析，可供设计参考。
Abstracts:
The medium voltage network of urban rail transit is an important link between main substation, traction power supply system and power and lighting power supply system. It also restricts the determination of the location and quantity of main substation. The division of ring network partition of operation and construction line has experienced the process of "short section", "long section" and "short section". The principles of several protection modes in different zones are expounded, and the protection reliability and power supply system maintenance are analyzed. At the same time, taking actual engineering application as example, the zoning forms of medium voltage ring network are compared, and division of partition is analyzed from aspects including tide current meter, protection method choice and cable investment, providing reference for design.
