Problems solved by technology
[0003] In the traditional method, the ultrasonic signal generated by the partial discharge is generally detected by the ultrasonic sensor installed near the high-voltage electrical equipment, but in the detection site, various noises often appear, which will affect the localization of the partial discharge. The positioning results have a large deviation

The invention relates to a partial discharge positioning method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a detection result of a partialdischarge ultrasonic signal output by an ultrasonic sensor; when the detection results of the ultrasonic sensors larger than or equal to a preset number threshold value are obtained, combining the detection results to obtain a plurality of detection result combinations; determining a corresponding candidate partial discharge position according to each detection result in each detection result combination; performing clustering analysis on the candidate partial discharge positions, and selecting a clustering cluster of which the average distance from each clustering element to a clustering center is smaller than a preset distance threshold from clustering clusters obtained through clustering analysis; and determining the partial discharge position represented by the clustering center of the selected clustering cluster as a final partial discharge position. The method can improve the positioning accuracy.
Description
technical field [0001] The present application relates to the fields of computer technology and electrical technology, in particular to a partial discharge localization method, device, computer equipment and storage medium. Background technique [0002] The insulating medium of electrical equipment will discharge locally under the action of a sufficiently strong electric field, and each partial discharge will have a certain impact on the insulating medium. This partial discharge is an important reason for the final insulation breakdown of high-voltage electrical equipment. An important indicator of insulation deterioration. Therefore, it is very important to accurately locate the location of partial discharge. [0003] In the traditional method, the ultrasonic signal generated by the partial discharge is generally detected by the ultrasonic sensor installed near the high-voltage electrical equipment. The positioning results have a large deviation. Contents of the inventi...
