Embodiment Construction
[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0016] In one embodiment, the bushing partial discharge charged detection device based on the directional antenna array, such as figure 1 shown, including:
[0017] The directional antenna array is used to detect the electromagnetic wave signal radiated by the partial discharge and convert it into a voltage signal output;
[0018] The signal conditioner is used to receive the voltage signal output by the directional antenna array, eliminate the received electromagnetic wave interference signal, amplify the voltage signal, and improve the signal-to-noise ratio;
