摘    要:长期以来,由于人为原因导致变压器接地侧零序差动保护误动事故时有发生,零差保护TA极性难以检验就成为制约该保护广泛应用的一个重要因素.文中介绍了RCS-985型零序差动保护在三相分体式和三相一体式主变上的现场投运试验,论述了一种利用保护装置自带录波功能,离线观察励磁涌流在变压器高压侧和中性点侧产生的零序电流相位的方法,能...

关 键 词:变压器  零序差动  励磁涌流  试验  故障录波

Abstract:In recent years,there always happened that transformer zero phase sequence differential protection false act for human factors.That zero phase sequence differential CT polarity was difficult to be detected is an important reason to restrict its development.This article introduced commissioning test used with RCS-985 zero phase sequence differential protector in three phase compact main transformer and three phase separate main transformer and discoursed a method that observed zero phase sequence current in ...
Keywords:transformer  zero-sequence differential protection  excitation inrush current  commission  fault recorder
