变压器用天然酯绝缘油研究现状
|
摘要
天然酯绝缘油作为一种高燃点、易降解的新型液体绝缘电介质,是未来环保产业发展的重要方向。由于天然酯自身的理化特性,天然酯绝缘油投运于变压器还面临着较多的挑战。介绍了国内外天然酯绝缘油的研究现状与趋势,分析了天然酯绝缘油的制备方法,分别从电气特性、理化特性、老化特性、亲水性、氧化安定性和生物降解特性方面阐述了天然酯绝缘油的相关研究成果及应用情况,指出了天然酯绝缘油投运于变压器需要解决的关键问题。
Natural ester insulating oil,as a novel type of liquid insulation dielectric,with advantages of highly flammable and biodegradable,is an important direction for future environmental protection industry. Due to the physicochemical characteristics of natural esters,the natural ester insulating oil putting into operation of the transformer faced with more challenges. The current status and trends of natural ester insulating oil were described and the preparation methods of natural ester insulating oil were analyzed.The related research progress and applications of natural ester insulating oil were described from the aspects of electrical characteristics,physicochemical properties,aging characteristics,hydrophilicity,oxidation stability and biodegradability. Finally,the key issues that needed to be solved when the natural ester insulating oil put into operation of the transformer were discussed.
