摘　　要：利用ANSYS分析软件建立三维模型,应用三维有限元非线性磁场分析计算出霍尔电流互感器开口气隙处的磁通密度。在此基础上,计算了铁心的饱和点并研究了气隙宽度对磁通密度的影响。实验表明计算方法和结果是正确的。The 3D model of current transformer was set up by ANSYS. The magnetic flux density in the gap was calculated by 3D finite element nonlinear analysis. Based on these results, the saturation point of core was calculated and the influence of gap parameter on magnetic flux density was studied. Experimental data shows that the calculation method and results are reliable.
