摘要

在高压变压器的现场安装时

降低变压器绝缘油中含气量是一项重要环节

也是评价变压器安装质量的一项重要指标。笔者针对现场实际并经实践提出对充氮保管的变压器

在通常的安装流程中

增加连续抽真空（首次注油前）48h及以上

最终可使绝缘油中含气量有明显的下降作用。

Abstract

Decreasing the gas content in insulating oil of transformer is very important during installalion on site

which is also an important index to evaluate the quality of instullation.In real practice

for a transformer filled with nitrogen in preservation

vacuum is taken out continuously（for the first time before infusing oil） for 48 hours or more.It is considered that this method is helpful in reducing the gas content of insulating oil.
