Tree-line contradiction is one of the common faults in current distribution network. Trees growing rapidly on both sides of the circuit not only bring fire hazards, but also affect the stable operation of the power grid. Especially in the south, the growth of trees is strong, it is easy to lead to the lack of safety distance, and the direct cutting involves the problem of dealing with the contradictions of the masses. The traditional tree-barrier clearing methods mainly rely on manual climbing, insulated bucket arm truck and other operation methods, but because the operators are too close to the live equipment, there are greater safety risks, not only the operation takes a long time and labor intensity, but also when the trees under the main line and the ultra-high trees on the side line endanger the safe operation of the line, the staff can not climb and trim the trees, which brings many difficulties to the tree-barrier clearing work.

Tradition removes tree barriers

By using laser to clean up the tree barrier, reduce the repeated power failure of the line and effectively improve the reliability of power supply, this way is to shine the high-energy laser beam issued by the "laser cannon" to the distant hidden points of the tree barrier, through remote heating, so that the branches are quickly charred, ablated, fused, and then fall naturally. The application of "laser cannon" is of great significance to improve the lean operation and maintenance level of transmission lines, reduce the safety risk and labor intensity of operators, and ensure the safe and stable operation of lines.

Laser removal Removes tree barriers

The whole set of laser obstacle clearing equipment weighs less than 20 kg, is portable, the maximum output power can reach 500 watts, and the output focusing spot size is less than 5mm at 100 meters and less than 4mm at 50 meters. The maximum working distance can reach 350 meters, the diameter of 20cm branches are easy to cope with, and the operation time usually only takes about 10 minutes. Through the operation of laser obstacle remover, manual climbing on the tower is avoided, and the operation efficiency and safety factor are greatly improved, especially in the spring stage of tree barrier surge, the efficiency of tree barrier clearing is greatly improved, and the safe operation of the line is guaranteed.
