全光纤型光纤电流传感器长期稳定性的实验研究

Experiment of Long Stability of Full-fiber Optical Fiber Current Sensor

本文报道了我们对于全光纤型光纤电流传感器试验样机在户外进行长期稳定性实验的结果。主要是环境温度的起伏对系统各部分的影响。实验结果表明:全光纤型光纤电流传感器其长期稳定性不能满足0.5％测量精度的要求,其主要原因是光纤质量不稳定,长期使用后其性能有较大变化。

This paper reported the experimental results of long stability of full-fiber optical fiber current sensor prototype in open air. The major is the effect of tempera-.ture fluctuation fln various system sections. The results show that the long stability of the sensor can not meet the requirement of measure accuracy of 0.5%. The main cause is the quality of optical fiber not stable. After long time use, its properties changed more.
