摘要

Due to its exceptional properties and cost-effectiveness, 1-phenyl-1-xylylethane (PXE) insulation oil is ideal for high voltage power capacitors. Nanoparticles have been proven effective in enhancing the overall performance of insulating oil. In this study, molecular simulation investigated the impact of temperature on water molecule diffusion, thermal stability, and dielectric properties in nano-SiO2 modified insulating oil. Results show that temperature promotes water molecule diffusion, but nano-SiO2 particles limit this increase. Similarly, higher temperatures reduce thermal stability and dielectric properties, yet nano-SiO2 particles only slightly affect these properties under high temperatures while maintaining favorable physical and electrical characteristics. This indicates that nano-SiO2 particles effectively limit water molecule diffusion and enhance thermal stability and dielectric properties, supporting nanoscale enhancements in insulation materials.
