摘要
在我国“双碳”战略驱动下,电力装备绿色化转型亟需环保绝缘液体支撑。合成酯绝缘油凭借高燃点、可生物降解及优异热稳定性,适用于环保和安全要求严苛的场景,是我国高端环保电力装备所需的关键绝缘材料。本文梳理了我国合成酯绝缘油的技术研发脉络,重点阐述多元醇酯分子设计、功能添加剂开发及混合油协同改性等核心技术突破,结合国产化设备应用案例,分析其在电力、新能源等领域的实践成效。研究指出,当前我国合成酯绝缘油技术已实现从实验室到产业化的跨越,但原料成本高、长期可靠性验证数据不足等瓶颈仍需突破。未来需通过生物基原料开发、连续化生产工艺升级,推动合成酯绝缘油在新型电力系统中的规模化应用,助力电力装备绿色转型。
Under the impetus of China's"dual-carbon"strategy,the green transformation of power equipment urgently requires environmentally friendly insulating liquids.Synthetic ester insulating oils,characterized by high fire points,biodegradability,and exceptional thermal stability,is suitable for environmentally and safely demanding scenarios.It is a key insulating materials for China's high-end eco-friendly power equipment.This review systematically examined the technological evolution of synthetic ester insulating oils in China,with a focus on breakthroughs in core technologies including molecular design of polyol esters,development of functional additives,and synergistic modification of blended oils.Combined with application cases of domestic equipment,their implementation effectiveness in power grids and renewable energy sectors were analyzed.The study highlights that China's synthetic ester insulating oil technologies have achieved laboratory-to-industrialization transitions,but bottlenecks such as high raw material costs and insufficient long-term reliability verification data still need to be overcome.In the future,it is necessary to promote the large-scale application of synthetic ester insulating oil in the novel power system through the development of bio-based raw materials and the upgrading of continuous production processes,to facilitate the green transformation of power equipment.
