摘要
结合一起主变跳闸事故,详细分析了主变差动保护在桥式接线时的CT二次接线原则和差动保护原理,并对类似的多种危险情况提出了防范措施。
According to an accident of false transformer tripping,this paper analyzed in detail the CT secondary wiring principle and the differential protection theory when the main transformer differential protection is in bridge connection.This paper also gave some precautionary measures for other similar dangerous conditions.
