Abstract

The invention discloses a cable terminal abnormity diagnosis method and device based on an infrared image. The method comprises the following steps: acquiring an infrared image of a to-be-tested cable terminal; analyzing the infrared image to obtain the surface temperature of the cable terminal to be measured in the infrared image; comparing the surface temperature with a preset temperature threshold to obtain a comparison result; and determining whether the to-be-tested cable terminal is abnormal or not according to the comparison result. According to the invention, the technical problem of low detection efficiency caused by manually detecting whether the cable terminal is abnormal or not in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of power monitoring, in particular to a method and device for abnormal diagnosis of cable terminals based on infrared images. Background technique [0002] With the rapid development of power grid construction, the power load is increasing rapidly, and people have higher and higher requirements for city beautification, power supply reliability, and power supply quality. It has been widely used in various voltage levels of the system, and its proportion in the urban power grid is getting higher and higher. Therefore, whether the power cable can operate safely has become an important factor for the reliable power supply of the power grid. Both theoretical analysis and actual operating observations show that the operating temperature usually rises after a potential problem occurs in the cable. Therefore, the operating temperature of the cable can reflect the operating state of the cable. Infrared thermal ima...
