宣汉某变电站主变跳闸引出的变压器剩磁问题分析

Analysis on Transformer Remanence that Arise from Generator Transformer Trip of Some Transformer Substation in Xuanhan

文章结合达州局辖区内一起主变跳闸事件,介绍了变压器剩磁的基本概念,建模分析了剩磁对主变波形的影响,最后指出了剩磁对电力主设备的危害,具有一定的工程指导意义。

Combined with the main transformer tripping event in Dazhou bureau areas,the basic concepts of transformer remanence are introduced,modeling analyzes the influence of remanence on waveform of the main transformer,and finally the hazards of remanence on the main electricity equipment are pointed out,which has a certain engineering guiding significance.
