摘要
本文用双标量位法对一台90MVA的三相电力变压器的漏磁场和短路时绕组的应力做了具体计算.结果表明,就窗口内部而言,漏磁场的分布与二维情况基本一致;但就电磁力而言,窗口内、外部的结果差别较大,应当采用三维计算.
This paper calculates the leakage field and forces on windings of a three phase power transformer by two scalar potential method'. It shows that within the window of transformer, the distribution of leakage field is nearly the same as that of 2-D ealculation; But as far as electromagnetic forces are concerned, the results are much different from each other so that 3-D calculation must be applied.
