摘　　要：GIS设备中微水含量超标威胁设备的安全及稳定运行。本文基于光电技术,研究了光谱吸收型光纤传感器检测GIS设备中的微水含量。采用半导体激光器光源,通过光源调制实现谐波检测,消除光源的不稳定和变化所引起的误差。光电测量方法不仅能精确测量微水含量,而且能实现在线检测,安全可靠。The moisture content over standard in GIS will threaten the operations of apparatus.Based on photoelectric technology,a method using absorption type optical fiber for GIS moisture detection is demonstrated.LD is used as a light source and light source modulation harmonic measurement is presented.The ratio of the fundamental and second harmonic signal can be used for eliminating the interference owing to light power changing.The method can not only accurately detect moisture content but also fit for on-line detection.
