摘要
对于船舶环境来说,因各类原因而产生的冲击对光纤电流互感器(FOCT)的影响不可忽略。分析了冲击对直波导共线型光纤电流互感器的影响,基于胡克定律和弹光效应建立了光纤延迟环在冲击机械应力作用下非互易性相位误差产生的数学模型,在模型中引入了机械平台固定部分的简谐受迫振动分析,并根据相关标准对FOCT样机进行了冲击试验,试验结果证明了误差数学模型的正确性,对分析补偿光纤电流互感器的冲击误差具有重要的意义。
In the marine environment,many reasons could cause an impact on the fiber-optic current transformer(FOCT).This paper studied the influence of impact on the straight waveguide collinear fiber-optic current transformer.It established the mathematical model of non-reciprocity phase error of optical fiber delay ring under mechanical impact based on Hooke's law and elastic-optic effect.This research brought the harmonically excited vibration analysis of the fixed part of the platform of machinery in the model,and the experiment of the FOCT prototype is carried out according to the relevant standards.The experimental results prove the correctness of the mathematical model of error,which has significant meaning for analyzing and compensating the impact error of the fiber-optic current transformer.
