摘要
针对煤矿井下电流检测存在的问题,文章设计出一种新型的光纤电流传感器,采用了具有几何相位补偿的传感头、双光路补偿的检测系统和DSP技术的信息处理系统。实验结果表明精度达到了0.3%,响应时间<2μs,达到了所需的高精度、实时性和稳定性要求。
Aiming at the problem in detecting the mine current, a new kind of fiber optical current sensor has been designed which includes geometric phase compensation sensor head, dual - light - path detecting system and signal processing system of DSP. The resuits of experiment show that acurracy reach 0.3%, response time reach under 2us, which prove that it should meet the requirments of high accuracy, real time and stability.
