输电线路覆冰监测拉力传感器性能测试
|
摘要
为实现基于输电线路覆冰的光纤Bragg光栅拉力传感器的性能分析,设计了一个量程为50kN的拉力传感器对其进行校准实验。通过实验中解调仪的中心波长和实验拉力机产生的拉力值进行线性拟合,求出该光纤Bragg光栅传感器的静态性能指标参数。结果表明:光纤传感器的灵敏度为28. 9N/nm,线性度为0. 91%FS,迟滞误差为0. 54%FS,零点漂移小。
In order to analyze performance of the optical fiber Bragg grating tension sensor for the icing of transmission line,a tension sensor which measuring 50 kN was designed to calibrate it. The parameters of static performance of the fiber Bragg grating sensor were obtained through linear fitting between central wavelength of the demodulator and the tensile force produced by the experimental tensile tester in the experiment. The experimental results show that,the sensitivity of optical fiber sensor is 28. 9 N/nm,the linearity is 0. 91% FS,the hysteresis error is 0. 54% FS and the zero drift is small.
