| Zusammenfassung: | The invention discloses an optical fiber transmission centralized local discharge monitoring device. The optical fiber transmission centralized local discharge monitoring device comprises a local discharge sensor, a photoelectric transducer, a signal centralized processor and a signal waveform processor, wherein the local discharge sensor is connected with the photoelectric transducer through a high-frequency coil; the photoelectric transducer is connected with the signal centralized processor through optical fiber; the signal centralized processor is connected with the signal waveform processor through a high-frequency coil, a control line and a network cable. The optical fiber transmission centralized local discharge monitoring device can perform loss-free and distortion-free photoelectric conversion on collected signals, perform signal monitoring of different frequency bands on multiple three-phase monitoring points simultaneously by matching an analog optical signal fiber transmission system terminal with |
