摘要
介绍了基于法拉第效应的光学电流互感器，对其光路系统进行了深入的研究。采用了一种全闭合的传感头结构并解决了光的耦合问题。从提高实用化光学电流传感器的可靠性出发，设计了一套具有光路自诊断能力的主辅光路系统，此传感器已在１１０ｋＶ变电站试运行。
The principle of an optical current transducer utilizing the Faraday effect is described.Itsoptical path has been deeply analyzed.Aclosed structure of sensing probe is used and the couplingproblem is solved. In order to enhance the reliabity of OCT, a set of main and supplemental opticalpath system with the ability of self-diagnose is proposed.The OCT has been test run in a ll0 kVsubstation.
