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. The physical, chemical, electrical, and thermal properties, along with the activation energy, have been significantly enhanced.

The invention discloses a method for manufacture sintered anode aluminum foil. Ultrasound was used to change the stacking structure of aluminum powder on the surface of the anode aluminum foil, allowing aluminum powder particles of different sizes to form a gradient distribution in the thickness of the aluminum powder layer, with a gradual decrease in average particle size from bottom to top, larger voids in the lower layer, and denser and larger surface area in the upper layer. Therefore, the specific capacitance and the withstand voltage were improved. By introducing ultrasonic vibration, this invention can simultaneously enhance the specific capacitance and withstand voltage of anode aluminum foil after high-temperature sintering and anodizing, while traditional sintering methods cannot obtain high specific capacitance and withstand voltage performance simultaneously.
