Abstract

The invention provides a method and a system for detecting icing thickness of an electric transmission line. The system comprises a camera and a remote detection device. The camera is mounted on the electric transmission line, and the remote detection device is connected with the camera through the Internet. The camera is used for shooting the electric transmission line to generate an electric transmission line image, and then sending the electric transmission line image to the remote detection device through the Internet. The remote detection device is used for comparing the electric transmission line image with a preset initial image to acquire the icing thickness corresponding to the transmission line image. The initial image is an image of the electric transmission line without icing. Since the camera is mounted on the electric transmission line to directly measure the thicknesses of a guide line and an iced guide line, a relative position of the camera and the electric transmission line is effectively fixed and accuracy of image measurement is improved.

Description

technical field [0001] The invention relates to the technical field of power monitoring, in particular to the detection technology of transmission lines in power systems, and specifically to a method and system for detecting the thickness of ice coating on transmission lines. Background technique [0002] Under certain micro-meteorological and micro-geographical conditions, the conductors of transmission lines often appear covered with ice. The overload caused by the icing of the conductors often causes mechanical accidents such as hardware damage, wire breakage, and tower collapse, and may also increase arc sag, resulting in electrical accidents such as flashover, burns, and wire burnout. Therefore, icing on transmission lines has a great impact on the safe operation of the power grid. In order to effectively prevent and deal with the hazards of icing, it is necessary to detect and warn the thickness of icing on transmission lines, and take timely measures such as manual d...
