Infrared and ultraviolet integrated failure early warning device

Abstract

The invention discloses an infrared and ultraviolet integrated failure early warning device, comprising an infrared imaging module, a visible light imaging module, an ultraviolet imaging module, and afailure early warning module. The failure early warning module is used for fusing images output by the imaging modules and pre-warning equipment after determining the equipment is faulty according tothe fused images. The ultraviolet imaging module comprises an ultraviolet CCD, a horizontal drive signal generation unit, a vertical drive signal generation unit and a bias voltage generation circuit, and is used for providing bias voltage for the horizontal drive signal generation unit and the voltage output by the vertical drive signal generation unit. With the invention, the fault of the equipment can be more comprehensively and conveniently detected, and fault early warning can be performed for detection staff.

Description

technical field [0001] The invention relates to the field of fault early warning, in particular to a fault early warning device integrating infrared and ultraviolet. Background technique [0002] After the high-voltage equipment is put into operation, due to reasons such as rough surface, pollution, structural defects, and poor conductor contact, the field strength of the equipment will be unevenly distributed, resulting in discharge phenomena such as corona and arcing. Corona and arc discharge will be accompanied by electricity, light, heat, sound waves, compounds, etc. At present, techniques for detecting partial discharge of electrical equipment using these characteristic signals include observation method, ultra-high frequency method, ultrasonic method, infrared imaging method, optical measurement method, insulating oil chromatography analysis method, and ultraviolet imaging method. Among them, infrared thermal imaging technology began to be applied to my country's elec...

Problems solved by technology

[0003] In practical application, the inventors of the present invention found that it is very inconvenient to use the existing method to detect equipment failures: on the one hand, the inspectors need to send the captured infrared or ultraviolet image information back to the inspection center for analysis before determining whether the equipment is faulty; On the one hand, the device used for ultraviolet imaging is very large, and it is not convenient for inspection personnel to carry it with them on site for fault detection
