摘　　要：采用Matlab软件对油纸绝缘材料的电导率的非线性变化规律进行了数值拟合,利用RC等效电路进行计算与分析,然后用ElecNet有限元分析软件对阀侧绕组端部电场进行仿真,分析了绝缘材料非线性对换流变压器极性反转电场分布的影响。Matlab software is used to numerically fit the nonlinear variation of the conductivity of oil-paper insulation materials, and the RC equivalent circuit is used for calculation and analysis. Then the analysis software of ElecNet finite element is used to simulate the electric field at the end of the valve side winding. The influence of material nonlinearity on the polarity reversal electric field distribution of the converter transformer is analyzed.
