Transformer oil is a refined electrical insulating oil that is widely used in power transformers and power distribution systems. The most important property of these oils is their dielectric properties, the reduction of which leads to a decrease in the lifespan of transformers. Nanofluids have a wide role in improving the properties of liquids in industrial applications. In this paper, MXene is a novel two-dimensional nanomaterial with unique properties which is added to the oil transformer to prepare a nanofluid. The TiAlC MAX phase was first synthesized from primary materials (Ti, Al, TiC), TiCT MXenes were prepared by etching Al from TiAlC and then the MAX phases were exfoliated using hydrofluoric acid (HF) in high concentrations. X-ray diffraction (XRD), Fourier transform infrared (FTIR) techniques, Raman spectroscopy and field emission scanning electron microscopy (FESEM) confirmed that TiAlC and TiCT were appropriately synthesized. MXene with different concentrations (0.01–0.1 wt%) was added to the used transformer oil. The results demonstrated that MXene increased the breakdown voltage, Tg delta, resistivity and relative permeability, by 31.7 %, 95.13 %, 85.15 % and 74.2 %, respectively. The study confirmed that the addition of MXene improved the dielectric properties of the transformer oil, resulting in the improved performance and stability of the transformer.

深入探讨应用 MXene 纳米颗粒增强变压器油性能的研究

变压器油是精炼的电绝缘油，广泛用于电力变压器和配电系统。这些油最重要的特性是其介电特性，介电特性的降低会导致变压器寿命的缩短。纳米流体在改善工业应用中液体的性能方面发挥着广泛的作用。本文将MXene作为一种具有独特性能的新型二维纳米材料添加到油变压器中制备纳米流体。TiAlC MAX 相首先由主要材料（Ti、Al、TiC）合成，通过从 TiAlC 中蚀刻 Al 制备 TiCT MXene，然后使用高浓度氢氟酸 (HF) 剥离 MAX 相。X射线衍射（XRD）、傅里叶变换红外（FTIR）技术、拉曼光谱和场发射扫描电子显微镜（FESEM）证实TiAlC和TiCT是正确合成的。将不同浓度（0.01-0.1 wt%）的 MXene 添加到废变压器油中。结果表明，MXene 使击穿电压、Tg delta、电阻率和相对磁导率分别提高了 31.7%、95.13%、85.15% 和 74.2%。研究证实，MXene的添加改善了变压器油的介电性能，从而提高了变压器的性能和稳定性。
