摘 要：以某110 kV有载调压变压器为例，从绕组涡流损耗计算、引线结构及电场分布、油箱机械强度等方面进行研究，并进行优化设计，通过选取合理的线规和匝绝缘厚度，来降低线圈运行过程中产生的涡流损耗和线圈幅向尺寸。通过仿真软件分析及样机试制，此优化结构实现了电力变压器小型化设计的目的，节省了原材料用量，降低了储油柜选用规格，节省了变压器运输费用。

Abstract: Taking certain 11 0 kV on-load tap changing transformer for example, research was made to the winding eddy current loss calculation, lead structure, electric field distribution and oil tank mechanical strength etc and the design was optimized. Via reasonable guage selection and turn insulation thickness, the eddy-current loss and coil width size could be reduced in operational process. The simulation software analysis and prototype trial-manufacture shows that this optimized structure realizes the miniaturization design of power transformer, saves the raw material quantity, reduces the select and use specification of oil conservator and saves the transformer transportation expenses.
Key words: on-load tap changing transformer; eddy-current loss; lead structure; oil tank mechanical strength; optimal design
