Partial discharge orientation system and method based on ultrahigh frequency sensor three-dimensional area array and clustering

Abstract

The invention discloses a partial discharge orientation system based on an ultrahigh frequency sensor three-dimensional area array and clustering. The partial discharge orientation system comprises a regular dodecahedron frame; the at least six dipole antennas are correspondingly arranged on at least six surfaces of the regular dodecahedron frame respectively; the processing module is connected with the data output end of each dipole antenna so as to receive ultrahigh frequency partial discharge signals detected by each dipole antenna; the processing module generates sample data based on the amplitude data of the ultrahigh frequency partial discharge signals detected by the dipole antennas, clusters the sample data, and takes the central value of the maximum class in the clustering result as the final orientation result of partial discharge. Correspondingly, based on the partial discharge orientation system, the invention further discloses a partial discharge orientation method based on the ultrahigh frequency sensor three-dimensional area array and clustering.

Description

technical field [0001] The present invention relates to an orientation system and method, in particular to a partial discharge orientation system and method. Background technique [0002] As we all know, in the power supply line, partial discharge (Partial Discharge, PD) is the main reason for the insulation failure of electrical equipment. When the insulation failure of electrical equipment occurs, it is easy to cause the entire power supply line to be paralyzed. [0003] Therefore, in order to timely feedback the operating status of electrical equipment, it is often necessary to detect partial discharge of electrical equipment and accurately orientate partial discharge, so as to provide important information for condition monitoring and maintenance of electrical equipment. [0004] At present, because UHF electromagnetic waves have good performance in terms of anti-interference, propagation speed, and sensitivity, etc., when partial discharge occurs in electrical equipment...
