摘要
阐述了全光纤电流互感器工作原理,基于法拉第磁旋光效应,综合利用光纤传感技术和闭环控制技术,使其精度和抗干扰能力等方面优于其他电子式电流互感器。介绍了该互感器在气体绝缘金属封闭开关设备(GIS)法兰中的集成方法,解决了传统互感器同GIS连接安装时存在的密封性问题,并大大减小了GIS整体体积,具有很好的发展前景。
Description was made on the working principle of a full optical fiber current transformer. On the basis of which was based on magnetic rotation Faraday Effect, the optical fiber sensing technology and closed-loop control technology were comprehensively utilized to make its accuracy and anti-interference capability etc, superior to other electronic current transformers. Introduction was made to the integration method of the transformer in gas insulated switchgear （GIS） flange, solving the existing sealing problem when a traditional transformer was installed and connected with GIS and greatly reducing GIS entire volume with good development prospect.
