绝缘材料的热稳定性是影响油浸式变压器寿命、过载能力的主要因素,从制备工艺、理化性能、电气性能及抗老化能力等方面对可用于油浸式变压器的高温固体绝缘材料和高温液体绝缘材料的研究进展进行了综述,提出了高温绝缘材料在油浸式变压器应用中需关注的问题.
The thermal stability of insulating material is the major factor affecting the life and overload capacity of oil-immersed transformers. The research progress of high-temperature solid and liquid insulat-ing materials for oil-immersed transformers was reviewed from preparation technology, physicochemical properties, dielectrical properties, and ageing resistance. Finally, some problems need to be concerned in the application of high-temperature insulating material in oil-immersed transformers were proposed.
