摘要
分析了城市轨道交通配电变压器各种电流特点,对配电变压器保护配置进行了研究,对各种保护提出了整定方法,对各种保护的保护范围和配合关系进行研究。介绍的保护整定方法可指导新建城市轨道交通工程的设计,也可用于已开通的轨道交通工程的校验。
The characteristics of various kinds of current in power distribution transformer of urban rail transitare analyzed, the protection configuration of power distribution transformer is studied, and the setting method for each protectionis proposed, which is related to the protection range and cooperative relationship for each kind of protection. The method of protection setting in this paper can guide the design of new rail transit construction, also be used for the calibration of already opened engineerings.
