摘要
本文将有限元方法用于大型电力变压器突发短路时瞬态电磁场计算，推导了轴对称非线性瞬态涡流场的有限元计算公式。针对一台 ２４０ ０００ ｋＶＡ电力变压器线圈短路电磁力进行了计算分析，得出了电磁力的分布曲线和瞬变规律。
The finite - element method is used in this paper for the calculation of transient electromagnetic field during the sudden short circuit of a large power transformer. Focusing the short - circuit electromagnetic force of the windings of a 240, 000kVA transformer, the calculation and analysis are carried out, the distribution curve and transient rule are obtained.
