针对传统光学电流传感器中常用的单导线缠绕磁光介质形式存在的对电磁场强度监测值较低的问题,设计了一种通过磁性材料铁氧体和磁光介质结合的光学电流传感结构。COMSOL仿真分析表明,设计的传感结构能通过光学传感进行监控测量磁场,进而达到测量电流的目的,并且与传统结构相比,测得的磁场强度值提高了3.05倍,进一步得到了线圈的最佳半径和最佳轴向截距。
Aiming at the low monitoring value of electromagnetic field strength in the form of single-wire wound magneto-optical medium commonly used in traditional optical current sensors, an optical current sensing structure combining magnetic material ferrite and magneto-optical medium is designed. The simulation analysis of COMSOL shows that the designed sensing structure can monitor and measure the magnetic field through optical sensing, and then achieve the purpose of measuring current. Compared with the traditional structure, the measured magnetic field strength value is increased by 3.05 times. The optimum radius and optimum axial intercept of the coil are obtained.
