[0025] Referring to the accompanying drawings, the best mode for carrying out the present invention will now be described below.
[0026] figure 1It shows a portable switch cabinet partial discharge inspection system, including a signal acquisition unit and a data processing unit. The signal acquisition unit is a plurality of signal acquisition units based on different switch cabinet non-embedded partial discharge detection technologies, including but not limited to Ultrasonic signal acquisition unit, ground wave signal acquisition unit, high-frequency current signal acquisition unit and environmental signal acquisition unit, different signal acquisition units collect corresponding partial discharge signals through corresponding sensors, and preprocess the received signals, including Signal differential amplification, filtering, signal following and analog-to-digital conversion, and then the digitized signal is transmitted to the data processing unit through the Bluetooth wire...
