摘要
全温范围内精度超差是制约全光纤电流互感器工程化应用的主要问题之一,针对该问题分析了全光纤电流互感器的工作原理,研究了温度对测量结果的影响,结合目前全光纤电流互感器的现场应用环境,提出了一种基于最小二乘法拟合的双路温度补偿算法,并通过实验验证了补偿算法的可行性。理论分析和实验结果表明,该算法可以在-40℃~70℃的范围内,将互感器的变比误差控制在0.2%以内,可以有效改善全光纤电流互感器在全温范围内的温度性能。
Accuracy decrease is one of problems that restricting engineering application of fiber optical current transformer （FOCT） .The function of FOCT is introduced .The influence of temperature on the measurement results were studied and the dual-way temperature compensation algorithm based on least square method were discussed .And its feasibility was verified by experiment . Analysis and experimental results show that this method improves the performance of FOCT in the whole temperature range .
