摘要
建立了油浸式变压器有限元计算模型,采用有限元方法对油浸式变压器的电磁场分布及金属结构件的涡流损耗进行了分析,讨论了屏蔽结构对变压器各部件附加损耗的影响。
The finite element model of oil-immersed transformer is established. The elec- tromagnetic field distribution and the eddy current loss of metal structural parts in oil- immersed transformer are analyzed with the finite element method. The influence of shielding structure to additional loss of transformer parts is discussed.
