| 摘 要： | 分析了全光纤电流互感器（FOCT）温度误差的主要来源,理论计算了温度变化下光纤λ/4波片与维尔德（Verdet）常数引入的误差,提出了一种温度误差补偿技术。通过在制作光纤λ/4波片时选择合适的初始相位延迟角,使λ/4波片引入误差与维尔德常数引入误差正好相反,从而达到相互补偿的目的。试验结果表明,通过补偿,FOCT能够满...

| Abstract: | The main temperature error sources of all-fiber optical current transformer(FOCT) are analyzed.The errors caused by fiber λ/4 waveplate and Verdet constant are calculated in theory.A temperature error compensation technology is presented,which uses the error caused by λ/4 waveplate to compensate for the error caused by Verdet constant by choosing appropriate original phase retardation angle of the λ/4 waveplate.The experimental results show that FOCT can satisfy the temperature cycle accuracy requirements of the 0.2 s class measuring electronic transformer. |
