摘要
互感器的关键器件之一是λ/4波片。针对不完美λ/4波片对系统的温度补偿作用,阐述了光纤电流互感器的原理,分析了传感环的温度特性,并给出了一组实验验证,实验结果表明,在没有温度补偿算法的情况下,相位延迟约为108°的波片相对于标准的波片对比差变化范围有0.9%的改善,较大地提高了系统的性能。
One of the key components of the transformer is the λ/4 wave plate. Aiming at the temperature compensation of the imperfect λ/4 wave plate to the system, this paper expounded the principle of optical current transformer, analyzed the temperature characteristic of sensing ring and gave a set of experimental verification. The experimental results show that without temperature compensation algorithm, there is 0.9% improvement on ratio error by replacing the standard wave plate with an imperfect λ/4 wave plate which has a phase delay of about 108°, so as to greatly improve the performance of the system.
