Abstract

An infrared detection method and device for electrical component faults, the method comprising the following steps: collecting infrared and visible light images of normal electrical components as standard images, collecting infrared and visible light images of electrical components to be tested during detection; The infrared image of the electrical component and the visible light image are processed accordingly to achieve a complete match between the visible light image and the infrared image; the processed visible light image of the component to be tested and the normal electrical component are registered to obtain an affine transformation matrix; The infrared image of the component is processed in grayscale, and its visible light image matching matrix is ​​used to complete the registration of the two grayscale images; the grayscale images of the two completely matched electrical components to be tested and the normal electrical components are compared and analyzed to obtain the differential ratio Alignment results; analyze differential alignment results to determine anomalies of electrical components under test. The method and the corresponding detection device realize the automatic identification of electrical component failures, and overcome the shortcomings of low efficiency, heavy workload, and high professional skill requirements of testing personnel for infrared manual detection of electrical component failures.

Description

technical field [0001] The invention relates to the field of fault detection of electrical equipment, in particular to an infrared detection method and device for faults of electrical components. Background technique [0002] Electrical components are mainly composed of contactors, relays, transformers, fuses and other switches. Due to long-term use and the influence of external conditions and other factors, it is prone to problems such as aging, loose wiring, and insulation failure. If these problems are not discovered and resolved in time, they will further lead to open circuit and short circuit faults of components, and eventually lead to the failure of the entire electrical system. Inability to work may endanger people's lives in severe cases. [0003] Infrared detection technology has the advantages of non-stop, non-contact, convenient operation, and intuitive detection results, etc., and has been better applied in the fault detection of electrical equipment. However,...
