摘要
介绍了光纤电流互感器的特点,与传统的互感器相比它的测量准确度高、暂态性能好、绝缘结构简单、尺寸小、造价低、升级性好。光纤电流互感器可分为两大类,一类是光电式电流互感器;另一类则为磁光式电流互感器。分别介绍了这两种光纤电流互感器的原理及结构特点,认为将光纤技术与微机技术有机地结合起来,应用于电力系统,尤其是变电站综合自动化系统,前景广阔。
The characteristics of optic fiber current transducer are introduced. Compared with the traditional transducer, it has higher measuring precision, better transient characteristic, simpler insulation structure, smaller size, lower cost and better scalability. Optic fiber current transducers can be divided into two groups: opto-electronic current transducer (OECT) and magnetic optical current transducer (MOCT). The principles and structure characteristics of these two types of optic fiber current transducers are presented. It has broad prospects to apply the optic fiber technique integrated with computer technique in the power systems, in particular, in the integrated substation automation system.
