摘要

变压器是输配电系统的关键部件。摘要制备了矿物油(MO)基多粒子纳米流体(MPNF)，通过加入$A1_{2}O_{3}$和TiO2纳米颗粒来提高MO的电性能。通过对模拟结果的分析，优化了填料的加载浓度和掺量配比，即$A1_{2}O_{3}$与TiO2纳米颗粒含量之比。测定了制备样品的交流击穿强度。结果表明，填料浓度为0.1重量百分比(wt%)、掺量比为9:1时，MPNF试样的交流击穿强度最高。在相同填料浓度下，纯油、$A1_{2}O_{3}$和TiO2 NFs的增强率分别为38.4%、15.86%和17.41%。

Optimization of Filler Loading of Multi-Particle Mineral Oil Nanofluid for Transformer Insulation

Transformers are critical components of electric power transmission and distribution system. Mineral oil (MO) based multi-particle nanofluid (MPNF) were prepared with an intention to enhance electrical properties of MO by incorporating $A1_{2}O_{3}$ and TiO2 nanoparticles. Filler loading concentration and mixing ratio, which is the ratio between $A1_{2}O_{3}$ and TiO2 nanoparticle content is optimized by analyzing the simulation results. AC breakdown strength of the prepared samples were measured. It is found that, MPNF sample having a filler loading concentration of 0.1weight percentage (wt%) and mixing ratio of 9:1 shows highest AC breakdown strength. This sample shows an enhancement of 38.4%, 15.86%, and 17.41%, w.r.t pure oil, $A1_{2}O_{3}$ and TiO2 NFs having same filler loading concentration.
