摘　　要：在介绍光学电流互感器原理和聚磁原理的基础上,给出了一种聚磁式光学电流互感器的结构,并对聚磁器通过ANSYS软件进行建模仿真,验证了不同气隙长度下的聚磁效果。试验结果表明,采用聚磁结构的光学电流互感器不但提高了光学电流互感器的灵敏度,而且具有较高的线性度,因而有着良好的应用前景。Basing on the introduction of theory of the optical current transformer and the theory of concentrating magnetism, this paper described a kind of structure of the optical current transformer with magnetic concentrator, simulated the magnetic concentrator and confirmed the effect of concentrating magnetism in different length of air gap with ANSYS. The test result indicates that the optical current transformer with structure of concentrating magnetism not only enhances sensitivity of the optical current transformer but also be of higher linearity, thus it has a good application prospect.
