摘要
详细介绍FOCT(全光纤电流互感器)的工作原理,分析LED驱动电流、光源温度、最大输入光强等参数与不同故障之间的关系,结合多起故障实例验证各参数对FOCT测量结果的影响,并对换流站现场运行维护工作提出建议,为提高直流输电工程中FOCT安全可靠运行提供参考。
The paper elaborates on the working principle of FOCT(fiber optical current transformer)and analyzes the relationship between faults and parameters such as LED driving current,light source temperature,maximum input light intensity.Given several fault examples,the influence of each parameter on FOCT measurement results is proved.Relevant suggestions are put forward for operation and maintenance in the converter station,which provides a reference for improving the safe and reliable operation of FOCT system in DC transmission projects.
