Abstract
The present disclosure relates to an optical fiber detection device for detecting a discharge fault of a high-voltage bushing, which includes an optical fiber sensing unit, an optical fiber delay unit, a photoelectric conversion unit, and a signal collecting and processing unit. The optical fiber sensing unit includes sensing optical fibers; the optical fiber delay unit includes delay optical fibers, a light source, and couplers; the photoelectric conversion unit includes a photodetector; the signal collecting and processing unit includes a high-pass filter. The delay optical fibers are connected to the couplers; an output end of the light source is connected to the light-splitting coupler; an input end of the photodetector is connected to the light-splitting coupler, and an output end of the photodetector is connected to the signal collecting and processing unit; and the light-combining coupler is connected to the sensing optical fibers.
