摘　　要：目前,我国电力行业大多使用传统的电磁式电流互感器存在许多问题,如绝缘性不好、成本高、体积大,已经不能满足新的发展需求。本文首先分析光电式电流互感器的工作原理,然后选择光电式电流互感器的类型和供电方案,最终设计了一款以Rogowski线圈和V/F变换为基础的光电式电流互感器。At present,most of China's electric power industry uses traditional electromagnetic current transformers.There are many problems,such as poor insulation,high cost,and large volume,which can no longer meet new development needs.This paper first analyzed the working principle of the photoelectric current transformer,then selected the type and power supply scheme of the photoelectric current transformer,and finally designed a photoelectric current transformer based on Rogowski coil and V/F transformation.
