摘要

箱式变压器是风电场进行能量传递的重要设备

针对某风电场连续发生的3起箱式变压器铁芯发热故障

对故障变压器开展油化分析、现场拆解

找到了引起发热的故障点。为对故障原因进行机理分析

采用有限元分析软件ANSYS MAXWELL建立涡流场分析模型

对变压器绕组、铁芯的发热情况进行量化计算。通过分析确定箱式变压器制造工艺存在缺陷

首端低压绕组与铁芯接触过于紧密是导致发热故障的原因。

Abstract

Package transformer is an important equipment for energy transfer in wind farm. Aiming at three cases of package transformer core heating faults occurring continuously in a wind farm

oil analysis and disintegration of the fault transformer are carried out

and the fault points causing the heating are found. In order to analyze the mechanism of the fault

the eddy current field analysis model is established by using finite element analysis software ANSYS MAXWELL to analyze the change.Quantitative calculation is carried out for the heating condition of the winding and core. Through the analysis

it is determined that there are defects in the manufacturing process of package transformer

and the reason of heating failure is that the low-voltage winding at the head contacts too closely with the iron core.
