The natural ester insulating oil transformer has advantages such as green environmental protection and strong overload capacity, which is an important development direction for the high-voltage and large capacity power transformer. The compatibility between insulating oil and insulating paint has a significant impact on the transformer design and operation maintenance. In this paper, the vegetable insulating oil and insulating paint materials were conducted thermal ageing experiments, and the compatibility between insulating oil and six commonly used insulating paint materials for power transformers was studied. The characteristic changes in the kinematic viscosity, moisture content, acid value, dielectric loss, breakdown voltage, and gas chromatography of natural ester insulating oil before and after thermal ageing were observed and analyzed. The results show that the structural integrity and functional stability of the insulating paint sheet remain good. Except for the kinematic viscosity, the physicochemical and electrical properties of the natural ester insulating oil have changed after ageing, but there is no significant deterioration. The dissolved gas content increases significantly after thermal ageing, and the gas chromatography results show good compatibility between insulating oil and insulating paint.
