摘要
本文笔者对差动保护装置的由来及特性进行了描述,并结合CT饱和所造成的影响,逐一分解出CT饱和原因所造成的差动保护动作情况,由此提出了基于减少短路的发生,选择合适的互感器及安装合适的继电保护装置等防止CT饱和的一系列方法。
In this paper,the author to differential protection device of the origin and characteristics are described,and the combined effect caused by CT saturation,one by one to decompose the reason of CT saturation caused by the differential protection action, is put forward in this paper based on the occurrence of short circuit is reduced,select suitable current transformer and the appropriate installation relay protection device to prevent a series of methods for CT saturation.
