摘要
通过对发生在武钢某变电所主变压器由于高压侧CT二次回路隐患导致区外故障时差动保护误动作跳闸事故的分析,指出加强CT二次回路全面检验的重要性,并对此次事故应吸取的教训和同类事故预防提出了对策。
Through analysis on the false tripping of the main transformer differential protection due to an external fault caused by hidden trouble in the high-voltage side CT secondary circuit at a substation in Wuhan Steel, the importance of enhancing overall inspection of CT secondary circuit in power system is pointed out and lessons to be drawn as well as prevention strategy for similar accidents are put forward.
