植物油纸绝缘及其变压器的研究进展与老化机理分析

Research Progress and Ageing Mechanism of Vegetable Oil-paper Insulation and Its Transformer

在石油资源紧缺与环境污染日趋严重的形势下,植物绝缘油重新成为关注热点,它将可能成为替换矿物绝缘油的新型液体绝缘介质。本文简要介绍了植物绝缘油的组成及电气和理化性能,总结了国内外植物绝缘油的研究进展。对植物油纸绝缘的老化机理进行了分析研究,列举了国内外植物油纸绝缘的研究现状,指出了国内外研究的局限性,最后概述了近年来植物绝缘油变压器的研究进展,并指出了其今后研究方向。

Under the situation of shortage of petroleum resources and increasingly serious environmental pollution, the vegetable insulating oil, which will probably become the new insulating liquid to replace the mineral insulating oil, becomes the focus of attention again. In this paper, the composition, electrical,physical and chemical properties of vegetable insulating oil were introduced briefly, and the research progress of vegetable insulating oils at home and abroad was summarized. The ageing mechanism of vegetable insulating oil-paper insulation was analyzed, and its research status and research limitation at home and abroad was listed. At last, the research progress of vegetable insulating oil transformers in recent years was summarized, and the research directions were proposed.
