针对目前电力系统对电流互感器的精度与灵敏度提出的更高要求，提出了一种基于金刚石氮-空位(NV)色心的全光直流互感器的系统方案，系统包括光源模块、激光反馈模块、激光分束模块、一次传感探头模块、激光分频模块、光电转换模块以及信号采集和数据处理模块。对系统中的磁屏蔽环进行了结构的设计与仿真，并对仿真结果进行了实验验证。最后搭建了单通道实验验证系统，系统实测结果表明，设计的全光直流互感器在5 000 A大电流下无磁屏蔽时可以达到0.35%的测量精度，加入磁屏蔽环后测量精度提升到了0.06%,从而为基于金刚石NV色心的全光直流互感器的研制提供了参考。
Abstract：In view of the higher requirements for the accuracy and sensitivity of the current transformer in the electrical power system, a system scheme of all-optical DC transformer based on diamond nitrogen-vacancy(NV) color center was proposed. The system included light source module, laser feedback module, laser beam splitting module, primary sensing probe module, laser frequency division module, photoelectric conversion module and signal acquisition and data processing module. The structure of the magnetic shielding ring in the system was designed and simulated, and the simulation results were verified by experiments. Finally, a single-channel experimental verification system was established. The system measurement results show that the designed all-optical DC transformer can achieve a measurement accuracy of 0.35% without magnetic shielding at a high current of 5 000 A. With the magnetic shielding ring, the measurement accuracy is increased to 0.06%, which provides reference for the development of all-optical DC transformers based on diamond NV color centers.
