摘要
根据电磁式电压互感器(PT)的铁心结构和绕组分布,利用磁路-电路对偶原理提出一种拓扑暂态模型进行了铁磁谐振仿真分析,计算出模型的磁滞损耗、漏感和绕组分布电容等参数,并分析了各参数对铁磁谐振过电压的影响规律。
Based on the core structure and winding distribution of electromagnetic-type voltage transformer(PT), a topological transient model is presented by magnetic circuitcircuit dual principle to simulate and analyse the ferroresonance resonance. The parameters such as hysteresis loss, leakage inductance and capacitance distribution of the model are calculated, and the influence of the parameters on the ferroresonance resonance overvoltage is analyzed.
