Abstract

The invention discloses a detection device, method and system for internal defects of a ceramic insulator. The method comprises the following steps: applying a light pulse heat excitation function toa ceramic insulator to be tested by using a light pulse heat excitation loading device; acquiring infrared thermal image sequences on the surface of the ceramic insulator to be tested by using an infrared thermal image acquisition device, and carrying out preprocessing such as fitting, compression and reconstruction on the acquired infrared thermal image sequences by using a data processor; according to defect information provided by original infrared heat image sequences obtained through preprocessing, analyzing and comparing data in a characteristic database, so as to obtain defect types andquantitative calculation results of the ceramic insulator. By adopting the detection device, the light pulse heat excitation function is applied to the surface of the ceramic insulator, defect typesare judged and defect information is analyzed according to variations of dynamic temperature fields on the surface of the ceramic insulator, the detection device has the characteristics of rapid measurement, large single-time measurement areas, visible measurement results, non contact, and the like, and related information of internal defects of the ceramic insulator can be accurately, comprehensively and deeply processed and analyzed.

Description

technical field [0001] The embodiments of the present application relate to the technical field of electric equipment detection, and in particular to a detection device, method and system for internal defects of porcelain insulators. Background technique [0002] Porcelain insulators are important equipment components of power transmission and transformation systems. They are widely used in power grid systems such as high-voltage transmission lines and substations. They play a role in mechanical support and electrical insulation for transmission wires. Due to the problems of ceramic technology and formula, porcelain insulators are prone to form pores, inclusions, micro-cracks and other defects during the manufacturing process, resulting in local stress concentration. Influenced by electromechanical loads and harsh environmental changes during long-term operation, insulator defects will further develop, and even fracture or breakdown failures will occur, seriously affecting t...
