摘要
变压器的性能受其绝缘系统的限制,目前在油浸式变压器中普遍使用绝缘纸以及绝缘纸板作为基本绝缘,而纤维素在高温下易发生水解,导致绝缘劣化。旨在提出实用的新型绝缘材料,论述并分析了若干种固体材料的绝缘性能,最后对各种聚合物固体绝缘材料的性能进行了比较。
In practical, the properties of insulation system are the key issues of the transformer performance. Now- adays the pressboard is adopted extensively in oil-filled transformers, while it is apt to be hydrolyzed and cause insulation degradation. To discover new practical insulation material, in this paper, several kinds of solid insulation materials have been analyzed . Finally properties of new polymer solid insulation materials are compared.
