220kV变压器中压绕组变形诊断分析

Diagnostic Analysis of Medium Voltage Winding Deformation of 220kV Transformer

本文中作者介绍了一起220k V变压器中压侧发生出口短路故障后对其中压绕组变形的诊断,分析了其形成原因,并对变压器绕组变形诊断方面提出了建议。

The diagnosis of the deformation of the medium-voltage winding after the occurrence of the outlet short-circuit fault on the medium-voltage side of the 220kV transformer is introduced by the authors in this paper.The cause of the formation is analyzed.Some suggestions for the transformer winding deformation diagnosis are presented.
