Abstract: The invention discloses a method and system for preparing multi-compound ester insulating oil. The method utilizes vacuum esterification, involving esterification of pentaerythritol and fatty acid, followed by vacuum distillation, adsorption, washing, suction filtration, and vacuum drying to produce pure synthetic ester insulating oil. By detecting saturated fatty acid content, polarization strength, and closed-cup flash point, the most suitable natural ester insulating oil is selected. Ten different proportions of mixed ester insulating oils are obtained through blending and tested for mass and heat changes in nitrogen and air environments. Dielectric performance parameters at varying temperatures are analyzed to calculate activation energy. The resulting mixed ester insulating oil, NSE3 (85 vol % KA+15 vol % FR3), exhibits a high flash point, low pour point, and high AC breakdown voltage, offering excellent comprehensive performance.
