Summary: | The invention discloses equipment and a method for detecting an electric arc in transformer oil based on an optical signal, and belongs to the technical field of electric arc detection. Comprising a plurality of optical fiber collimating lenses arranged in the transformer; after detecting an optical signal in the transformer, the optical fiber collimating mirror transmits the optical signal to a photoelectric detector arranged outside the transformer, and the photoelectric detector is connected with a control system of the transformer; and the photoelectric detector is used for judging whether an arc fault occurs in the transformer. The optical fiber collimating mirror is directly arranged in the transformer to detect optical signals, then the optical signals are transmitted to the external photoelectric detector, the optical signals are strong, electromagnetic interference in the transformer is avoided, the detection accuracy is improved, and the problem that arc faults generated in the transformer cannot be |
