摘要
建立了典型干式变压器三维磁热耦合计算模型,通过数值分析得到了绕组损耗及热点温升沿圆周方向和高度方向的分布规律。
A three-dimensional magneto-thermal coupling calculation model for a typical dry-type transformer is established. The distribution rules of winding loss and hot-point temperature rise along the direction of circumference and height are obtained through numerical analysis.
