How troublesome is the removal of foreign bodies in power grid transmission lines? Generally, the removal of foreign bodies is performed by means of live operation, that is, two people enter the tower operation, and three people cooperate on the ground. It is time-consuming and laborious, moreover, the operators need to bear a higher safety risk. If the foreign body is wrapped around the center of the vertical arc of the grounding guide line, it is also necessary to comprehensively consider the lower-environment along the line, the operation process is more complex and cumbersome, and more personnel are also required to cooperate.
In foreign body removal and repair work, the most complex and dangerous situation is rainy weather. Because the workers can not operate in live operation, and must apply for line power failure to carry out rush repair. The power failure operation process is very long, range from an hour to a few hours. Moreover, due to the wet slippery pole tower, the safety risk is great, and the difficulty of operation on the tower is also greatly increased.
High altitude artificial obstacle removal
"Novel useful tool" bring a qualitative leap, and since they are equipped with laser obstacle remover, these problems have been solved. Laser obstacle remover consists of modules such as optical fibers, mobile power supplies, extinction devices, and night operations, and relies on high-reliability optical fiber lasers to effectively remove line foreign bodies less than 200 meters. "With this 'new weapon', removing lead foreign bodies can be quickly and easily completed. Compared with the traditional live operation, it has a very large advantage,in summary, it is safe, time-saving, labor-saving, human-saving, convenient, and all-weather. It can be described as a qualitative leap.
Obstacle removal by laser obstacle remover
No need for personnel climbing on the tower, only two people required to cooperate with the ground, by one person operating the hand-held controller to aim at the foreign body and controlling the movement of light spot, and the other person controlling the laser power supply and adjusting the laser frequency, and the line foreign body can be removed from the ground at a distance as soon as 1 minute. Foreign bodies hanging in the center of the guide wire arc can also be quickly handled, greatly reducing the labor intensity and safety risks of rush repair personnel. More importantly operation of laser obstacle remover is not affected by the weather, and foreign matter can be easily removed in rainy weather without applying for line power outages, which has greatly improved power grid power supply reliability. Its transmitting power can also be adjusted to achieve the removal of foreign matter without producing an open flame. It will not only cause any damage to the equipment itself, but also not pose a threat to other facilities such as houses and trees under the line.
