Power transmission line laser external force damage prevention monitoring and early warning device

Abstract

The invention belongs to the field of power systems, and relates to a power transmission line laser external force damage prevention monitoring and early warning device. All-weather monitoring is performed in the region of frequent construction, high number of trees in the passage and frequent human and animal activities outside the power transmission line by using laser detection and the camera video transmission device based on the laser intelligent detection technology and the image monitoring technology through combination of the characteristics of the power transmission line, and the external damage hidden trouble can be warned in the early stage and discovered in time and eliminated so that the failure trip rate of the power transmission line can be reduced and the reliability of thepower transmission line can be enhanced. The actual demand of the present high voltage power transmission line and tower safety monitoring can be greatly met so that the power transmission line inspection efficiency can be effectively enhanced, and powerful guarantee can be provided for enhancing the modern management level of the high voltage power transmission line of the power industry.

Description

technical field [0001] The invention belongs to the field of electric power systems, and relates to a laser anti-external force damage monitoring and early warning device for power transmission lines. Efficiency provides a strong guarantee for improving the modern management level of high-voltage transmission lines in the power industry. Background technique [0002] With the rapid development of the national economy and the continuous expansion of the city scale, the transmission lines are becoming more and more dense, and the operating environment is becoming more and more complex; many transmission lines span roads, railways, bridges, rivers, lakes, mountains, buildings, etc. The safety of the environment is increasingly threatened by various illegal constructions, illegal buildings, illegal trees, floating objects and bird damage. [0003] In recent years, accidents of transmission lines damaged by external forces have occurred frequently across the country. For example...

AI Technical Summary

Problems solved by technology

[0003] In recent years, accidents of transmission lines damaged by external forces have occurred frequently across the country. For example, the construction site is under or near the transmission line, and construction equipment (mainly cranes, excavators, concrete mixers and other tall construction machinery) are in operation. Among them, its tall and protruding part sometimes enters the safety limit of the transmission line, causing the line to discharge it, and even hits the transmission line, causing tripping and power outage accidents

Another example is that when the transmission line crosses the highway, due to the super high vehicle height and the lack of warning signs on the transmission line, the transmission line is damaged; when some transmission lines cross the river, some large ships, sand dredgers and other equipment are not loaded at high tide. In the case of cargo passing under the transmission line, its super high part causes damage to the transmission line, etc.

There are also some lines that span buildings or forest areas. The growth of trees and the action of wind cause insufficient insulation distance between lines and trees and discharge occurs.

[0004] According to the survey, in view of how to prevent external forces from damaging transmission lines in power systems, relevant research at home and abroad is mainly devoted to three directions: (1) Radar microwave monitoring: the technical principle of this method is feasible, but due to the high cost, it cannot be widely used

(2) Video surveillance: Manual 24-hour real-time monitoring. However, there are many links and a long time from the discovery of hidden dangers to the on-site alarm prompt. Now there are research directions that use image recognition technology to realize object intrusion alarm, but it is also limited by the recognition accuracy and There are two problems with the false alarm rate of early warning and there is no effective and mature solution

(3) Infrared or common laser anti-arming method, this method has great limitations, and it has not been popularized and applied due to the disadvantage of high false alarm rate

[0005] In summary, in view of the fact that domestic high-voltage transmission lines are severely damaged by external forces, the present invention has developed a set of laser anti-external force damage monitoring and early warning devices for transmission lines, and constructed a remote protection network for transmission lines to prevent external forces from destroying transmission line accidents in time. occur
