提出了一种基于普克尔效应的双晶体光学电压互感器。设计了双晶体光学电压传感单元和光学电压互感器系统。设计了3种互感器加压方式，并在常温条件下进行了交流实验。实验结果表明该传感单元在3种加压方式下的输出都具有良好的线性关系，响应迅速，无延迟；输出波形较好，无失真。在传感单元上直接接电极引出线测量灵敏度最强，金属圆筒和平行平板加压方式下互感器输出的变比误差较小，电压较高时变比误差不大于±0.12%。表明了该互感器设计方案的可行性，为下一步原理性样机的研制提供参考。

An optical voltage transformer with double-crystal based on Pockels effect was presented. An optical voltage sensing unit with double-crystal and an optical voltage transformer system were designed. Three kinds of method for applying voltage to the transformer were designed. The AC experiments were carried out at room temperature. The experimental results show that the output of the transformer with the three methods has a good linear relationship and response quickly without delay. And the output waveform is good and without distortion. The method that directly connected electrode on the sensing unit has the highest measurement sensitivity. The method that applied voltage with metal cylinder and parallel plates have the smaller ratio error. The ratio error is less than ± 0. 12% when the input voltage is high. The experimental results show the feasibility of the design scheme and provide reference for next step research of principled sample machines.
