Partial discharge detection method, system and equipment based on imaging mode

The invention provides a partial discharge detection method, system and device based on an imaging mode, and relates to the technical field of power detection. The detection method comprises the following steps: S1, acquiring imaging data of power equipment, and determining a plurality of abnormal regions based on the imaging data; s2, determining an abnormal coefficient of each abnormal region; and S3, based on the determined abnormal coefficient, calculating to obtain an equipment abnormal emergency value, and determining a fault emergency signal of the power equipment according to the equipment abnormal emergency value. According to the invention, the abnormal area, namely the position where partial discharge exists, can be obtained, and a fault emergency signal can be further obtained to effectively judge the emergency degree of partial discharge at different positions. On the basis, the problems that in the prior art, a single infrared detection method is adopted for partial discharge detection, the dete
