摘要
用于测量电力系统电流的光学电流互感器由于具有许多传统的电磁感应式电流互感器无法比拟的优点 ,具有广阔的应用前景。文中给出了基于法拉第磁光效应、以光纤为介质的光学电流互感器的基本原理和研究现状 ,重点论述为了加快实用化进程需要加以深入研究和解决的问题 ,包括新型的传感材料和传感头结构的研究、克服双折射效应、与光纤通信相结合等。
Optical current transducer used to measure the current of power system is superior to electromagnet- induced current transducer in m any aspects.It has wide foreground of application and imm ense potential of m arket.This paper offers basic principle and the presentresearch situation of the optical current transducer,which uses optical fiber as a m edium on the basis of Farady m agneto- optical effect.It especially lays em phasis on problem s to be researched deeply and resolved for purpose of accelerating the process of practical applications,i.e.researching material and structure of new sensing head, elim inating birefringence effect,com bining with optical fiber com munication.
