色谱分析法在钢铁厂新投运110 kV变压器故障诊断中的应用

Application of Chromatographic Analysis in Fault Diagnosis of Newly Operated 110kV Transformer in Steel Plant

某大型钢铁厂二期工程新建一座110kV变电站,其中新投运的1#主变存在特征气体H2含量超标。文章运用色谱法对该问题的原因进行分析,并采取滤油等措施解决了该问题,为以后变压器再出现此类问题提供了借鉴经验。

A 110 kV substation was newly built in the second phase of a large steel plant,in which the H2 content of the characteristic gas in the newly-operated 1# main transformer exceeded the standard.This paper analyzes the causes of this phenomenon by chromatography,and adopts measures such as oil filtration to solve this problem,which provides reference experience for similar problems in transformers in the future.
