摘　　要：针对光学玻璃电流传感头光学参量对光学电流互感器性能影响问题,提出了采用正交共轭反射镜作为一次电流传感元件的光学电流传感器设计方案,报告了系统的光路设置,建立了系统的数学模型,导出了其工作原理的解析表达式,给出了验证性实验结果,讨论了该设计的优、缺点及克服缺点可能的技术措施.研究结果表明,该设计方案是合理的,可被实验验证的.经过实用化开发后,其有可能成为实用型光学电流互感器的一种方案.To solve the problems induced by the influences of the reflection-induced retardance and linear birefringence existing inside the glass current sensing elements to optical current transformers, a design of the optical current sensor is proposed using a Faraday mirror as the primary current sensing element. The paper showed optical setup, established the mathematical model, derived the working principle, given the experimental result, and discussed the advantages and shortcomings of the design. The results show that the design is rational and experimentally verifiable. After development, this design might be one practically applicable optical current transformer design.
