摘 要：以某110 kV有載調(diào)壓變壓器為例，從繞組渦流損耗計算、引線結(jié)構(gòu)及電場分布、油箱機械強度等方面進行研究，并進行優(yōu)化設(shè)計，通過選取合理的線規(guī)和匝絕緣厚度，來降低線圈運行過程中產(chǎn)生的渦流損耗和線圈幅向尺寸。通過仿真軟件分析及樣機試制，此優(yōu)化結(jié)構(gòu)實現(xiàn)了電力變壓器小型化設(shè)計的目的，節(jié)省了原材料用量，降低了儲油柜選用規(guī)格，節(jié)省了變壓器運輸費用。
關(guān)鍵詞：有載調(diào)壓變壓器；渦流損耗；引線結(jié)構(gòu)；油箱機械強度；優(yōu)化設(shè)計

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
