光纤电流传感器检测系统的分析
Analysis of detection system of fiber current sensors
摘要
本文给出了光纤电流传感器的两种检测方案:单路检测系统和双路检测系统。比较了他们的各自特点。分析表明:双路检测系统有较高的信噪比,较强的抗干扰能力,不仅可以探测交流大电流,也可用于测量直流大电流,是目前光纤电流传感器信号检测的较好方案之一;单路检测系统具有结构简单,调整方便,对探测器、放大器无特殊要求等优点,在其它光纤传感系统中(如光纤电压计)具有实用意义。
Abstract
Two detection systems of fiber current sensors are described and compared in this paper. The analyses indicates that the double way detection system has higher level of SNB and stronger ability of suppressing distrubances than the single way detection system. It is not only used for measuring AC hut also DC and is considered to be the better detection system of fiber current sensors. The ^single way detection system has advanteges of simple structure, convenient adjustment and no special requirement for photodetector and amplifier. It is also useful in other fiber sensors such as fiber voltage meter.
