| Zusammenfassung: | The invention provides a discharge signal processing device. The discharge signal processing device comprises a signal acquisition module, a signal amplification device, a polarity reversal module, a bipolar detection module, a lock-in amplification unit, an alarm module and a multi-level power supply. The signal acquisition module is connected with the signal amplification device, one end of the bipolar detection module is connected with the signal amplification device and the polarity reversal module, the other end of the bipolar detection module is connected with the phase-locked amplification unit, and the phase-locked amplification unit is connected with the alarm module. The signal acquisition module is used for coupling a discharge signal generated in a power equipment insulation system and converting the discharge signal into a voltage or current signal, and the alarm module is used for carrying out strength judgment on an output signal of the phase-locked amplification unit and sending an alarm signa |
