变压器相序错接一例浅析

Effect of Wrong Phase Sequence Connection of Transformer

介绍了一例变压器相序接错的情况,并对其影响进行了分析。结果表明:对于Yyn0接线的配电变压器,无论相序如何错接,只要高、低压侧相序对应一致,变压器的联结组别必定保持不变,对变压器本身、并联运行的其他变压器以及接入的系统均不产生影响。

The wrong phase sequence connection of transformer and its effects are described and analyzed. indicate that, for YynO connection type transformer, no matter how wrong phase sequence is, the transformer group will remain unchanged if only keep the phase sequence of high voltage side corresponding to that of the side, which has no effects on the transformer itself, the other parallel operating transformers and the access The results connection low voltage system.
