    摘 要:針對(duì)變壓器損耗計(jì)算模型復(fù)雜、計(jì)算量較大、計(jì)算精度要求高的問(wèn)題,提出了建立精細(xì)化計(jì)算模型的損耗計(jì)算方法。分析了傳統(tǒng)繞組模型計(jì)算損耗產(chǎn)生偏差的原因,并建立變壓器繞組的精細(xì)化仿真模型,研究變壓器油箱、夾件內(nèi)的損耗分布及熱源分布特性。對(duì)變壓器進(jìn)行負(fù)載損耗試驗(yàn),結(jié)果表明:精細(xì)化模型計(jì)算得出的負(fù)載損耗誤差為 0.69%,實(shí)現(xiàn)了更高的損耗計(jì)算精度,為變壓器的損耗計(jì)算提供了參考。

    Abstract: In order to solve problems of complex calculation models, large calculation amount and high calculation accuracy of transformer power loss, the paper puts forward a refined power loss calculation model. It first analyzes the causes of power loss calculation deviation of the traditional winding model, and then builds a refined simulation model of transformer winding to make research on loss distribution and heat source distribution of transformer tanks and clamps. After the load loss test of the transformer, it is found that the load loss error calculated by the refined model is 0.69% which is more accurate than that of the traditional model, providing great reference for transformer power loss calculation.
    Key words: oil-immersed transformer; power loss calculation; winding model; refined model
