This review is focused on the research of dielectric fluids, especially commonly used power transformer oils enhanced by nanoparticles, i.e., nanofluids. There are differences between various combinations of base fluids and nanoparticles prepared in different ways. The main goal of this review was to present recent research in this field sorted by the used nanoparticles. Nanofluids based on mineral oils, natural, or synthetic esters were investigated in terms of the nature of nanoparticles, particularly AlO, TiO, FeO, FeO, graphene, fullerene, and others. The combinations of environmentally friendly oils and nanoparticles were presented. Finally, the article focused on the description of current dielectric fluids usable in power transformers and the possibilities of improving new and existing fluids with nanoparticles, especially their physical, dielectric, and chemical properties, but with regard to environmental aspects.
本综述聚焦于介电液的研究，尤其是通过纳米颗粒增强的常用电力变压器油，即纳米流体。以不同方式制备的基础液和纳米颗粒的各种组合之间存在差异。本综述的主要目的是按照所使用的纳米颗粒对该领域的最新研究进行介绍。基于矿物油、天然或合成酯的纳米流体根据纳米颗粒的性质进行了研究，特别是氧化铝、二氧化钛、氧化铁、氧化亚铁、石墨烯、富勒烯等。文中介绍了环境友好型油与纳米颗粒的组合。最后，本文着重描述了目前可用于电力变压器的介电液，以及利用纳米颗粒改善新型和现有流体的可能性，特别是它们的物理、介电和化学性质，但同时也考虑了环境因素。
