摘　　要：为了提高输电效率,需对电能损耗的影响因素进行分析,而电晕损耗是影响电能损耗的重要因素之一。以新型节能导线为试验研究对象,在干燥、小降雨量、大降雨量以及涂污等不同工况下,对3类节能导线的电晕损耗和起晕电压进行试验分析,并通过ANSYS建模仿真,分析不同外径导线和水滴大小对电场强度的影响。结果表明:导线半径越大,导线表面电场强度越小,水滴模型半径越大,导线表面场强越大。In order to improve the transmission efficiency,the power loss of the factors were analyzed,and corona loss is one of the important factors that affect the power loss. In this paper,newenergy-saving wire as test subjects in different conditions of drying,lowrainfall,high rainfall and smeared condition. Corona loss and the corona onset voltage of energy-saving conductor are tested and analyzed. And through the ANSYS modeling and simulation analysis the effects of different conductor diameter and droplet size on the strength of electric field.The results showed that the larger the radius of the wire the smaller conductor surface electric field intensity,the larger the radius of the droplet model,the larger the surface field strength of the conductor.
