摘　　要：本文采用Ansoft电磁场有限元分析软件,建立了有限元分析模型,对CRH3高速动车组牵引变压器在突发短路情况下的三维漏磁场进行了分析,然后应用虚位移法计算了各绕组短路电磁力的分布情况,为同类型变压器的机械稳定性设计提供理论数据。Using Ansoft electromagnetic field finite element analysis software, this paper established a finite element analysis model of the high-speed CRH3 bullet shell type transformer under the condition of sudden short circuit of three dimensional leakage magnetic field is analyzed, then the application of virtual displacement method to calculate the winding short-circuit the distribution of electromagnetic force, for the mechanical stability of the same kind of transformer design to provide theoretical data.
