Investigation of Nano-SiO2 Modified Power Capacitor Insulating Oil Behavior in Micro-Water Environments at Different Temperatures
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.
期刊介绍：
The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science. There are no restrictions on disciplinary boundaries provided the focus is on silicon-based materials or adds significantly to the understanding of such materials. Accordingly, such contributions are welcome in the areas of inorganic and organic chemistry, physics, biology, engineering, nanoscience, environmental science, electronics and optoelectronics, and modeling and theory. Relevant silicon-based materials include, but are not limited to, semiconductors, polymers, composites, ceramics, glasses, coatings, resins, composites, small molecules, and thin films.
