[0023] Embodiment:

[0024] like Figure 1 , Figure 2 As shown, a multi-channel partial discharge detection device suitable for unmanned aerial vehicles comprises a main shell 1, a cavity is opened inside the main shell 1, a core board 9 is arranged on the top of the inner side of the cavity, a core board mounting plate 8 is fixedly connected to the copper column by screws at the bottom of the core board 9, an array board mounting plate 5 is arranged below the core board mounting plate 8, the array board mounting plate 5 is fixedly installed in the cavity of the main shell 1 by screws, a sound absorbing structure 7 is installed between the array board mounting plate 5 and the core board mounting plate 8, a sound print array plate 3 is installed below the array board mounting plate 5, a camera 4 is connected above the sound print array plate 3 by screws, a sound insulation structure 2 is fixedly installed on the inner wall of the cavity below the sound print array plate 3 to improve the sound insulation effect, and a dust plug 6 is arranged on the surface of the upper cover 10 on one side away from the skyport connector 11;

[0025] The partial discharge detection device is a device specially used to detect potential insulation faults in power equipment. It receives the high-frequency pulse signal generated by the power equipment and analyzes the spectrum characteristics of the signal to determine whether the equipment has insulation faults. The multi-channel partial discharge device is usually composed of a high-frequency sensor, a data acquisition module, a signal processing unit, and a display control terminal. When the insulation inside the power equipment is damaged or aged, partial discharge phenomena will occur. These partial discharge phenomena will be transmitted in the form of high-frequency pulse signals; the multi-channel partial discharge device first senses and collects the high-frequency pulse signal through the sensor, and performs pre-processing operations such as amplification and filtering. Subsequently, the signal is subjected to spectrum analysis and feature extraction using signal processing technology, such as fast Fourier transform FFT. By comparing with the known fault spectrum database, it is possible to accurately determine whether the equipment has potential insulation faults.

[0026] Lightweight design: The multi-channel partial discharge detection device is made of aluminum-magnesium alloy and has a lightweight design with hollowed-out internal mounting parts to ensure the flight stability and safety of the drone. The multi-channel partial discharge detection device needs to be equipped with a highly sensitive sensor that can accurately detect partial discharge signals and transmit the test results to the ground control center in a timely manner for subsequent analysis and processing. The partial discharge signals of multiple channels are monitored and analyzed simultaneously, and compared with each other to enhance the accuracy and stability of the detection. The multi-channel partial discharge detection device carried by the drone can quickly and efficiently perform partial discharge detection on large-area equipment or facilities, saving manpower and time costs. The multi-channel partial discharge detection device can monitor the signals of multiple channels at the same time, improving the precision and accuracy of the detection and avoiding missed detection or false detection. The drone can perform partial discharge detection in dangerous or inaccessible environments, reducing risks and safety hazards to personnel. The drone can fly in the air and can cover a large area for partial discharge detection, which is suitable for various terrains and environments. The multi-channel partial discharge detection device can monitor the changes in partial discharge signals in real time, detect problems in a timely manner and take measures to avoid damage to equipment or facilities.
