摘　　要：本文对双正交全反射法光学电流互感器传感头的精度进行了分析,分析结果表明采用小折射率的磁光材料以及大入射角传感头方案可以降低对加工精度的要求。同时对双正交全反射法和临界角入射法这两种设计方案中加工精度对传感器精度的影响进行了比较,得出了双正交全反射法在加工精度要求方面较临界角入射法宽松的结论。The accuracy of optic current sensor with dual-layer circuit has been analyzed in this paper. The results indicate that the sensor head adopting small index of material and large incident angle will reduce requirement of machining accuracy. The influences of the manufacturing error of sensor heads with dual-layer circuit method and critical angle method have been compared as well, the manufacturing accuracy required by the former method is lower than that of the latter method.
