大型电力变压器线圈短路稳定性的三维有限元分析

Analysis of Stability of Large Power Transformers Coils under Short-circuit Condition using the Three Dimensions Finite Element Method

针对大型电力变压器在短路状态下线圈稳定性问题,建立线圈的三维立体计算模型,采用空间梁单元,用有限元方法分析了线圈空间失稳的各阶临界载荷与失稳模态.

This paper use a three dimensions model of large power transformer coil to discuss its stability under short-circuit condition and calcuktes its spatial unstable critical loads and mode-shapes by spatial beam element.
