摘要

为了查找110 kV堡子店2号主变压器投运后色谱异常的原因

采用色谱跟踪结合电气试验数据进行综合分析

证实铁心片间短路是该故障的诱因

并对短路缺陷进行了处理

提出在变压器安装吊芯检查时

应将铁心连片解开

测量铁心级间绝缘电阻

防止铁心片间短路导致运行故障。

Abstract

In order to investigate the reasons of chromatogaram abnormal after the NO.2 transformer start working

comprehensive analysis was carried out by combining chromatogaram tracking with electric experiment data.The abnormal reason was caused by short circuit between iron core

and the defect of short circuit was treated.It is put forward that interstage insulated resistance between iron core should be measured during the period of the installation and inspection of transformer core

so as to prevent the fault caused by the short circuit of iron core interstage.
