直流换流站中全光纤电流互感器光源退化故障研究
Research on the Degradation Faults of Fiber Optical Current Transformer Light Source in DC Converter Stations
摘要
Abstract
Fiber optical current transformers(FOCTs)have been widely used in the DC converter stations.However,with the increase of operating time,there is a common problem of decreased output optical power of super luminescent diode(SLD)light source devices in the FOCT,which reduces the operational reliability of FOCT.This article provides a theoretical analysis of the degradation problem of SLD light sources.We have also conducted dismantling tests on light sources with severe optical power attenuation,and obtained statistical data on the optical power of SLD chips.The final conclusion is that the degradation of the chip area is the main cause of the attenuation of the output light power of the light source,which is a common phenomenon.In actual production activities,it is necessary to perform regular detection of the SLD optical power to avoid unnecessary causes.关键词
