Temperature Field Analysis of Windings of Natural Ester Insulating Oil-immersed Transformer 110 kV Environment Friendly
摘要
Abstract
Oil-immersed power transformer is one of the most important power equipments in power network system,and insulation oil is the main cooling medium of it.At present,mineral insulating oil is widely used,it is not easy to degrade and cause environmental damage after leakage.Natural ester as a new insulating oil for transformer can solve the above problems perfectly.It is a more ideal insulating cooling medium.However,the mechanical and electrical properties of natural ester insulating oil and mineral insulating oil are quite different,and its influence on transformer structure design and winding heat dissipation needs to be further studied.In this paper,a 110 kV natural ester insulat-ed oil transformer is taken as the research object.Based on the finite element analysis,the temperature field distribu-tion of its winding is calculated and the influence of natural ester and mineral oil on the heat dissipation of the wind-ing are compared,which provides a feasible scheme for the design of large capacity natural ester insulated oil-im-mersed transformer.关键词
