电力变压器绕组变形的诊断

Diagnosis of the winding deformation of the power transformer

当变压器发生外部短路事故后,应诊断变压器绕组是否存在变形、位移或匝间短路。文章介绍诊断方法并给出实例。

It is necessary to analyze whether the transformer winding have deformation, displacement or the short circuit between turns after the external short circuit of the transformer This paper introduces the diagnosis method, and the corresponding example is given.
