一起500 kV变压器油含气量超注意值原因分析

Cause Analysis of a 500 kV Transformer Oil Gas Content Exceeding the Attention Value

在介绍变压器油含气量色谱试验的意义和试验方法原理的基础上,通过实际生产经验和实例分析,归纳出油中含气量异常增大导致超注意值的原因,进行分析探讨,为快速准确查找变压器密封不良的缺陷和消缺,提供方法及建议。

Based on the introduction of the significance of gas content chromatographic test of transformer oil and the principle of test method, through the actual production experience and case analysis, the reasons for the abnormal increase of gas content in oil leading to the over attention value are summarized. Analysis and discussion are carried out to provide methods and suggestions for quickly and accurately finding and eliminating the defects of poor sealing of transformers.
