Electric power equipment defect analysis device

Abstract

The invention discloses an electric power equipment defect analysis device, and relates to the field of electric power equipment detection. By the aid of the electric power equipment defect analysis device, the problems of frequent difficulty in discovering slight electric corona, tracking and electric arc generated by early defects of electric power equipment and severe electromagnetic interference in power grids can be solved. The electric power equipment defect analysis device comprises an electromagnetic receiving loop, an ultrasonic receiving loop, a processing circuit, a directional antenna housing and an ultrasonic sound collection cover. The ultrasonic sound collection cover is connected with an input end of the electromagnetic receiving loop, so that the directions and the locations of electromagnetic sources can be determined; the ultrasonic sound collection cover is connected with an input end of the ultrasonic receiving loop, so that the directions and the locations of ultrasonic sources can be determined. According to the technical scheme, the electric power equipment defect analysis device has the advantages that the directions and the locations of the electromagneticsources can be determined by the directional antenna housing and the electromagnetic receiving loop, the directions and the locations of the ultrasonic sources can be determined by the ultrasonic sound collection cover and the ultrasonic receiving loop, accordingly, the nearest locations of faults can be determined, and the properties of defects can be judged; equipment with minor defects can beaccurately and quickly searched and judged.

Description

technical field [0001] The invention relates to the field of electric equipment detection, in particular to an electric equipment defect analysis device. Background technique [0002] In power equipment such as insulators, power cables, switches, busbars, etc., the corona, electric traces, and arcs generated by early defects are relatively light, and are often not easy to be found, because these equipment will not produce obvious corona discharge. The discharge sound waves, the uncertain approximate position is a little far away, and it is difficult to be received by the ultrasonic waves, but these slight equipment defects will generate large electromagnetic wave interference in the power grid. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, and to provide a defect analysis device for electric equipment, with the purpose of realizing t...
