摘要 超辐射发光二极管（SLD）光源在光纤电流互感器（FOCT）运行过程中大多有光功率衰减现象,这对FOCT的使用寿命有较大影响。为分析SLD光源性能衰减故障,对5组试品开展性能试验,通过试验分析SLD光源耦合结构,测试SLD光源中管芯与尾纤的耦合性能,并分析SLD光源性能衰减的原因。结果表明,管芯与光纤耦合失效和叠加引脚焊接失效是引起光源衰减的主要原因。

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.
