Abstract

Disclosed is a non-lens discharge positioning device and method. In the device, a wide-angle camera module is arranged on the top surface of a conical pedestal to collect image digital signals of discharge. The planar photoelectric sensing array includes a plurality of planar photoelectric sensors, and : A plurality of planar photoelectric sensors centered on the wide-angle camera module and uniformly arrayed in a fan shape on the side surface of the conical base. The angle between the plane normal vectors of the plurality of planar photoelectric sensors is not zero. The planar photoelectric sensor array is used for : Perform photoelectric conversion on the light beam generated by the discharge, and output multiple analog signals; the central processing unit connects the image processing unit and the multi-channel digital acquisition unit to receive and superimpose image grayscale data and digital signals. The central processing unit includes: superimposed image Grayscale data and digital signals generate a calculation unit for the discharge light radiation angle.

Description

technical field [0001] The invention relates to the technical field of electric equipment discharge detection, in particular to a non-lens discharge positioning device and method. Background technique [0002] The corona discharge generated by the external insulation of power equipment and the partial discharge generated by the internal insulation of the equipment are important factors that endanger the insulation safety of power equipment. The detection of corona discharge and partial discharge is an important means to check the state of external insulation and internal insulation of power equipment. The live detection (non-electrical contact detection) of corona discharge and partial discharge is the main application form at present. [0003] For the corona discharge of the external insulation of the equipment, it is generally detected by the ultraviolet imager or the ultraviolet pulse detector. The former can realize the visual positioning of the corona discharge, and it...
