摘要

2012年以来

光纤电流互感器（FOCT）因其不断暴露出的可靠性问题

工程应用量逐年下降。为此

针对FOCT故障诊断方法

相关研究人员和企业也作出了建设性的尝试。文中介绍了FOCT的基本原理和工程应用现状

分析了其常见故障模式和主要组成部件的故障率。针对FOCT的突变性故障和渐变性故障

分别综述了基于解析模型、基于信号处理和基于知识处理的故障诊断方法。最后对FOCT故障诊断方法的研究工作进行了展望

提出了采用集成光路的FOCT和综合化、智能化的故障诊断方法

将会是今后的研究热点。

Abstract

The engineering application of fiber optical current transformer（FOCT）has decreased year by year since2012 due to its reliability problems. Many researchers and enterprises have made attempts at fault diagnosis methodsof FOCT. In this paper

the basic principle and engineering applications of FOCT are elaborated

and the commonfault modes and failure rate of its main components are analyzed. Three methods for diagnosing soft and hard faults ofFOCT are reviewed

including the methods based on respective analytic model

signal processing

and knowledgeprocessing. Moreover

the research trend in the fault diagnosis of FOCT is prospected

that is

the integrated and in-telligentized fault diagnosis method

as well as the FOCT with integrated optical circuit（IOC）.
