摘要
利用能量变分原理,应用有限元方法计算了三相三柱干式变压器空载条件下的磁场分布和铁心振动位移,分析了铁心周围的声场分布。
Based on energy conversion principle, the magnetic field distribution and core vibration displacement of three-phase with the finite element method under three-limb dry-type transformer are calculated no load condition. The sound field distribution around core is analyzed. The validity of the strong-coupling model is verified with the calculated and tested results.
