The partial discharge detection circuits are connected to a plurality of ports of the CPU one to one, respectively. First, a partial discharge pulse signal is filtered and amplified by means of a partial discharge pulse signal processing module in the partial discharge detection circuits, and is then inputted to a comparator, and a reference voltage passes through the CPU and is sent to a reference voltage processing module for amplification, filtering and other processing, and then is inputted to the comparator, so that the comparator processes same according to the partial discharge pulse signal and the reference voltage and then inputs same to a trigger. Finally, according to a level signal at an output terminal of the trigger, the CPU determines whether partial discharge occurs in a circuit to be detected.Type: ApplicationFiled: December 6, 2021Publication date: January 4, 2024Applicant: CHINA SOUTHERN POWER GRID TECHNOLOGY CO., LTD.Inventors: Quan SHI, Qifu LU, Longhua TANG, Wang RAN, Ming FU, Dong FU, Wei DENG
