Abstract

The invention relates to the technical field of power transmission lines, in particular to a foreign matter eliminating method for an overhead line. The method comprises the following steps: collecting an image of the overhead line by an unmanned plane, and setting longitude and latitude information on the image; carrying out analysis on the image of the collected overhead line to obtain an image threshold, finding out preset image information of the overhead line at the longitude and latitude in a normal condition according to the longitude and latitude information on the image; if the image information exceeds the preset health threshold, controlling the unmanned plane to carry out foreign matter elimination; and if the image information is within the preset health threshold range, further carrying out image analysis. Aiming at the foreign matters of kites, packaging bags and the like on the overhead line, by the methods that the unmanned plane enters an electric field in a charged manner and charged elimination is carried out, the efficiency and the safety are improved; and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a method for eliminating foreign objects in overhead lines. Background technique [0002] Overhead lines mainly refer to overhead open lines, erected above the ground, and are transmission lines that use insulators to fix the transmission wires on the towers standing on the ground to transmit electric energy. It is convenient to erect and maintain, and the cost is low, but it is easily affected by weather and environment (such as strong wind, lightning strike, pollution, ice and snow, etc.) . [0003] Due to the wide distribution of overhead lines and their long-term operation in the open air, they are often affected by changes in the surrounding environment and nature, resulting in various faults in the operation of overhead lines, such as kites on overhead lines, Foreign objects such as packaging bags. Ensuring continuous power supply is the basic requiremen...
