摘要
分析了变压器励磁涌流产生的原因、励磁涌流的特点及对差动保护的影响,对目前采用的几种励磁涌流制动差动保护方案进行比较、分析,提出一种改进的制动方案。
This paper analyzed the causes of the inrush current of transformer,and its characteristic and influence on differential protection.Compared and analyzed several inrush current restraint differential protection schemes.This paper also presented an improved braking scheme.
