变压器绝缘材料老化判断的方法探讨

Discussion on Evaluation the Aging of Insulation Materials in the Power Transformer

绝缘材料的寿命是变压器的使用寿命标志,阐述了绝缘材料在变压器运行中老化的原因、绝缘材料老化分解产生CO、CO2及糠醛的机理,重点探讨了如何通过测定变压器油中CO、CO2的含量以及糠醛的含量两种途径来分析判断变压器绝缘材料的老化程度。

This paper is about evaluation of the aging of insulation materials in power transformer that means the age of transformer. It explains the reasons that would made insulation materials of running transformer aging and the generation mechanism of CO, CO, and furfural. It focuses on evaluation of the aging of insulation materials by these two ways: CO, CO, content and furfural content.
