| Zusammenfassung: | The utility model provides a partial discharge detection signal acquisition device and system using magnetic effect, the signal acquisition device comprises a signal acquisition sensor, the signal acquisition sensor comprises a TMR magnetic sensor, the partial discharge detection system using magnetic effect comprises the signal acquisition device, and the partial discharge detection system also comprises a signal processing device. And the signal processing device is connected with the TMR magnetic sensor and is used for receiving signals acquired by the TMR magnetic sensor and processing thesignals. The TMR magnetic sensor is used for collecting partial discharge signals, interference signals generated by self-excitation oscillation of an inductor and a capacitor in the electromagneticantenna can be effectively prevented from affecting accuracy of detection results, meanwhile, magnetic lines of force are gathered through the high-frequency magnetic material, detection sensitivity is effectively improved, an |
