摘要
为了提高光纤电流互感器在应用过程中的性能,需要对光纤电流互感器的性能分析方法进行研究。当前分析方法不能准确的分析外部因素对光纤电流互感器性能造成的影响。提出一种环境温度和线性双折射对光纤电流互感器的性能分析方法,分析得到环境温度会改变光纤电流互感器中波片的相位延迟角,进而影响互感器的测量值;通过建立光纤电流互感器响应度特性数学模型分析光纤电流互感器受线性双折射的影响,得到线性双折射越高对光纤电流互感器的影响越大。实验结果表明,环境温度优化后互感器测得的电流相对误差变小,线性双折射越低互感器的比差越接近于零,与所提方法得到的结论一致。
In order to improve the performance of the fiber-optic current transformer in the application process,it is necessary to study the performance analysis method of the fiber-optic current transformer.Current analytical methods do not accurately analyze the effects of external factors on the performance of fiber optic current transformers.A performance analysis method of ambient temperature and linear birefringence for fiber-optic current transformer is proposed.It is analyzed that the ambient temperature will change the phase retardation angle of the wave plate in the fiber-optic current transformer,which will affect the measured value of the transformer;The mathematical model of the responsivity characteristics of the fiber optic current transformer is affected by the linear birefringence,and the higher the linear birefringence is,the greater the influence on the fiber optic current transformer.The experimental results show that the current relative error measured by the transformer becomes smaller after the ambient temperature is optimized,and the lower the linear birefringence,the closer the ratio of the transformer is to zero,which is consistent with the conclusion obtained by the proposed method.
