Analysis on super luminescent diode light source attenuation fault of fiber optical current transformer
摘要
Abstract
Super luminescent diode(SLD)light source mostly has optical power attenuation phenomenon in the operation process of fiber optical current transformer(FOCT),which has a great impact on the service life of FOCT.In order to analyze the performance attenuation fault of SLD light source,a total of 5 groups of samples are collected to carry out performance test and failure analysis.The coupling structure of SLD light source is analyzed,the coupling performance of the tube core and the tail fiber in the SLD light source is tested,and the reasons for the performance attenuation of SLD light source are analyzed.Finally,the coupling failure of the tube core and the fiber and the stacked pin welding failure are the main reasons for the attenuation of the light source.关键词
