RESEARCH PROGRESS AND DEVELOPMENT PROSPECT OF NATURAL ESTER INSULATING OIL

Abstract

Abstract: With the increasing demand for energy and the increasing emphasis on environmental protection, natural ester insulating oil has gradually become a green substitute for mineral oil due to its outstanding fire safety performance, excellent natural degradation ability and good insulation properties. The development status of natural ester insulating oil at domestic and abroad was reviewed, and the current quality standards of natural ester transformer oil were compared and analyzed. The disadvantages of natural ester insulating oil in heat dissipation performance, low-temperature performance, oxidation stability and electrical performance were summarized.The latest research trends and improvement methods were summarized. In addition, typical products of natural ester insulating oil in the market were summarized and its future development was prospected, which provided guidance for power equipment oil.

Key words: insulating oil, natural ester, insulating property, mineral oil
