摘要
描述了电力变压器铁心电磁振动的数字模型建立过程,讨论了如何从能量守恒和功能转换的角度描述表征磁致伸缩现象的磁场力,并导出了变压器铁心电磁振动的数学模型。
The process to set up the mathematical model for the electromagnetic vibration in power transformer cores is described.Based on energy convervation and transformation,the magnetic forces of magnetostriction phenomenon are discussed.And the mathematical model for the electromagnetic vibration in transformer cores is derived.
