摘要
对一台变压器产品进行了二维有限元建模,重点考虑了实际绕组材料的弹塑性,结合"磁-结构"耦合理论,得到绕组在短路时的弹塑性形变随时间变化的规律。
The 2 D finite element model of a transformer is established. The elasticity and plasticity of actual winding materials are considered. According to the magnetic-structure coupling theory, the variation regulation of elastoplastic deformation with time during short circuit of winding is obtained.
