摘　　要：传统对电力变压器绕组中暂态电压分布的仿真计算有多种,但均需编程计算而得,为此提出了一种适用于PSpice仿真的电力变压器绕组中暂态电压分布的电路模型,并对该变压器雷电过电压时的暂态电压分布及正常运行电压分布进行了仿真,结果表明该模型可表达绕组暂态时的表现,且大大简化了计算过程。The traditional simulating calculation of transient voltage distribution in the power transformer windings is a subject about which many papers have been written,but results of them need program. In this paper,a transient circuit model used in simulating calculation by PSpice is described. In addition,the author also simulates the transient voltage distribution of that power transformer under lighting over voltage as well as the normal - loaded state. Results of simulating calculation show that the model can represent the characteristics of the transformer and simplify the process of calculation.
