Among some wire entanglements, the kite with steel wire skeleton is the most threatening, which may directly lead to short circuit and affect the safe and stable operation of the line.
Although some entanglements are not conductive in themselves, they are prone to moisture and conductivity, which can still cause line trips and affect the stable operation of the power grid. In extreme cases, they can even cause large-scale power outages.
In recent years, the biggest threat to the safe operation of transmission lines has come from external damage, of which nearly two-thirds are caused by foreign objects similar to kites.
The device that emits laser light looks like a camera, commonly known as a laser obstacle remover machine, commonly known as a "laser cannon".
In order to clear obstacles, in the past, operation and maintenance personnel had to wear electric field shielding suits and climb dozens of meters high transmission line towers to clean them up; In case of rain, it is necessary to cut off power for operation; When obstacles are entangled in the center of the high-voltage line sag, it is necessary to use tools such as pulleys to "grind" back and forth, which is inefficient and carries certain risks.
Later, the maintenance company established a "Eagle Eye" team to use drones to spray fire and clear obstacles. However, the stability of unmanned aerial vehicles loaded with gasoline is difficult to control, and a safe distance of 5 meters must be maintained from the high-voltage line, which puts higher requirements on the operating environment and the psychological quality of maintenance personnel.
The laser obstacle remover machine can adjust the distance from the obstacle and emit the laser with the corresponding power to quickly eliminate the foreign matters in the line within 200 meters without generating open fire and affecting the buildings, trees and other facilities below the line.
The laser obstacle remover machine has undergone a disruptive change in the way floating objects are removed.
