中文摘要：

变压器的电磁分析在科学研究和工程应用中一直是一种研究变压器故障的重要方法。目前基于FRA的变压器绕组的建模多数都是单一的电路模型，忽略的磁场方面的重要作用。因此利用大型多物理场耦合软件建立变压器绕组的二维有限元模型，用场路耦合的方法实现了变压器的漏磁场仿真。模拟了绕组的变形故障，采用FRA的方法分析研究绕组径向的变形尺寸以及发生变形的位置对变压器绕组的传递函数的影响，对变压器绕组故障的研究提供一定的理论指导。

英文摘要：

transformer electromagnetic analysis in scientific and engineering applications has been an importara research method of transformer deformation- At present, most transformer winding models are single circuit models ignoring the important role of magnetic field It modeled a two-dimensional finite element model of the transformer windings by using large scale muhi-physics coupling software and simulated the leakage magnetic of the transformer by coupling magnetic field and circuit. After modeling the winding deformation model, the frequency response analysis method was used to research impact on transfer function of the transformer winding, which depends on the degree and position of the winding radial deformation.
