摘　　要：建立供能电流互感器在线性及非线性工作区的离散数值模型,得到一次回路额定电流、二次负载、结构参数、二次输出电流及输出功率的定量关系。根据以上数值模型优化供能互感器结构参数,经试验结果验证供能电流互感器数值模型的合理性,并达到设计优化目标。A discrete numerical model of the power supply current transformer in linear and nonlinear working areas was set up and the quantitative relation between the output current,power and other parameters,such as primary current,secondary load and structure parameters was given.Then on the basis of the model,the structure parameters optimization was carried out.It can be shown that the model is effective and feasible by the comparison of experimental and simulation results.The experimental results confirm that optimized parameters are feasible and it can reach optimization goal.
