This paper focuses on characterization of a natural ester oil, based on corn, which has been nanostructured by carbon quantum dots (CQD) decorated nano fillers. Partial discharge (PD), lightning impulse (LI) and AC power frequency breakdown strength of corn oil, pure and nanostructured by CQD-treated SiO2 and TiO2 nanoparticles, are measured for different concentration of nanofillers with mass fractions of 0.01, 0.05 and 0.1. It is shown that the addition of CQD-treated SiO2 nanofillers improve considerably oil insulation performance already at very low nanoparticle concentration, which indicates promising potentiality for transformer insulation applications, from compact design to long-term performance.

开发环保纳米结构油：变压器玉米油的局部放电和击穿电压表征

本文重点介绍基于玉米的天然酯油的表征，该油已通过碳量子点 (CQD) 装饰的纳米填料进行纳米结构化。针对不同浓度的纳米填料（质量分数为 0.01、0.05 和 0.1），测量了由 CQD 处理的 SiO2 和 TiO2 纳米颗粒纯和纳米结构的玉米油的局部放电 (PD)、闪电脉冲 (LI) 和交流电源频率击穿强度。结果表明，添加经 CQD 处理的 SiO2 纳米填料已经在非常低的纳米颗粒浓度下显着提高了油绝缘性能，这表明从紧凑设计到长期性能的变压器绝缘应用具有广阔的潜力。
