Abstract

Natural esters exhibit excellent flame retardant and biodegradability, which help minimize power accidents and reduce environmental impact. These qualities make natural esters a promising alternative to conventional transformer insulating oils. However, the practical applications of natural esters in power equipment have been significantly restricted by their inherent limitations, including elevated viscosity, high dielectric loss, and poor oxidative stability. Nano-modification technologies present a novel methodological approach to solve these inherent constraints. A systematic analysis of the latest research developments in nano-modified natural ester transformer oils is provided in this review. The properties of various natural esters are examined, and their suitability as base fluids is evaluated, while the modification effects and mechanisms of typical nano-additives are comprehensively reviewed. The key role of nano-modification technology in improving the overall performance of natural esters is elucidated through detailed analysis of how nanoparticles influence physical properties, dielectric properties, and oxidative stability. In addition, the practical challenges facing nano-modification technology are addressed, providing valuable theoretical guidance for future developments in this field.

纳米改性剂提高天然酯类变压器油的性能：挑战与未来方向

天然酯具有优异的阻燃性和可生物降解性，有助于减少电力事故，减少对环境的影响。这些特性使天然酯成为传统变压器绝缘油的有希望的替代品。然而，天然酯在电力设备中的实际应用受到其固有局限性的极大限制，包括高粘度、高介电损耗和氧化稳定性差。纳米修饰技术提供了一种新的方法来解决这些固有的限制。本文对纳米改性天然酯变压器油的最新研究进展进行了系统的分析。考察了各种天然酯的性能，评价了其作为基液的适用性，并对典型纳米添加剂的改性效果和机理进行了综述。通过详细分析纳米粒子对天然酯的物理性能、介电性能和氧化稳定性的影响，阐明了纳米修饰技术在提高天然酯整体性能方面的关键作用。此外，还讨论了纳米改性技术面临的实际挑战，为该领域的未来发展提供了有价值的理论指导。
