摘要
通过联系一起主变故障跳闸实例,简要分析了在主变差动保护动作后利用主变保护的各侧故障波形缩小故障点范围的思路和方法,为快速有效地对主变三侧一次设备进行故障点的查找提高理论依据。
According to the wave printed by protection equipments of transformer,it is discussed that the general way to analyze the cause of a transformer tripping in this article. And the paper tried to provide the theory basis to find the fault point of the kind of accident more quickly and more efficiently.
