摘要
考虑铁心磁致伸缩的体积变化效应,建立变压器油箱体积振动模型,计算了球壳油箱的体积耦联振动自振频率,并对直流偏磁时变压器油箱振动和噪声案例进行分析。
Considering the effect of the core volume changing caused by magnetostriction the model of transformer oil tank volume expansion-contraction vibration is established The coupled vibration frequency between a spherical oil tank and the oil is calculated The noise and tank vibration of a DC biastransformer are analysed.
