摘要
通过对北郊变电站变压器差动保护误动原因的分析 ,说明变压器差动保护装置对零序电流处理正确与否直接影响着差动保护装置的动作 ,因此在设计、安装及整定保护装置时 ,要根据变压器各种不同的运行情况 。
Through the analysis of the misoperation of transformer differential relay in Beijiao Substation, the paper shows whether the zero sequence current is dealt with well or not directly affects the operation of differential relay. And the paper advances that zero sequence current must be treated effectively according to various operating conditions of transformers in the course of design, installation and setting of relay.
