Example Embodiment

[0056] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0057] Aiming at the problem of tree barrier measurement for ground conductors of transmission lines, the present invention proposes a tree barrier measurement system for overhead power transmission lines, which can realize the measurement of hidden danger clearance at any location in the transmission line corridor within the line of sight. The system includes: a multi-rotor flying device and a ranging device; the ranging device is installed dire...

Abstract

The invention provides a tree obstacle measurement system and a method used for an overhead transmission line. The system comprises a multi-rotor flight device and a distance measurement device which is installed right below the multi-rotor flight device. The multi-rotor flight device is used for carrying the distance measurement device to fly to the place above a tree and to stop flight in a position which is equal to the overhead transmission line. The horizontal distance between the multi-motor flight device and the overhead transmission line is a preset safe distance. The overhead transmission line is above the tree. The distance measurement device is used for measuring the vertical distance between the multi-rotor flight device and the tree below. According to the invention, the tree obstacle measurement system can be used for carrying out tree obstacle measurement without power cut and working at a high place; the tree obstacle clearance distance can be safely, quickly and conveniently measured; tree obstacle information can be time and precisely grasped; and safe and reliable circuit operation is ensured.

Description

technical field [0001] The invention relates to the technical field of tree barrier measurement, in particular to a tree barrier measurement system and method for overhead transmission lines. Background technique [0002] With the rapid development of the national economy, the contradiction between the planting of economic crops in the area where the line passes and the protection requirements of the transmission line is becoming more and more obvious. The unrestricted growth of trees in the line passage may cause tree barrier flashover accidents, which has become a major hidden danger that threatens the safe operation of the line. . On August 14, 2003, the main reason for the world-shocking blackout in the United States and Canada was the tree flash failure of the line. The tree flash fault seriously weakened the robustness of the power grid and eventually led to the system collapse. [0003] In order to better solve the increasingly prominent "line-tree contradiction" and...
