Power grid overhead line foreign body hanging is one of the causes of unplanned shutdown of the line. In the past, if foreign object was found on the high-voltage line, it had to be removed manually by electric maintenance personnel climbing up the base tower and walking on the high-voltage line more than 80 meters above the ground. The current cleaning methods mainly include UAV spray cleaning, insulated bucket arm vehicle lifting extraction, etc., but the above technology or cleaning instruments are too close to the live line with safety risks, or long operation time, high labor intensity, high labor risk. If there is hanging foreign object in overhead line, how can we safely and quickly get these hanging wire foreign body?
STP Laser Co., Ltd. cooperated with the Provincial Power Institute and developed power grid laser obstacle remover. LHW-3 CO2 laser obstacle remover can emit controllable lasers from the ground to cut and remove high-altitude foreign bodies at a long distance, with an effective range of 150 meters. It is safe, rapid and charged, and is suitable for the removal of non-metallic foreign bodies in most overhead lines. No power outages and people climbing pole towers, easy operation, time-saving and labor-saving, and no damage to the wire. "For example, when there is a kite hanging line, the removal order of the kite body and kite line can be reasonably arranged, and the foreign body removal can be successfully completed." The head of the STP laser said it not only melts or vaporizes foreign bodies on high-voltage lines in the 60-200 meter high air instantly through the laser beam it emits, but also does not cause any damage to the high-voltage lines. LHW-3 CO2 laser obstacle remover can be used to remove kites, advertising cloth, agricultural plastic film and other foreign bodies hanging on high-voltage power lines in high altitude, a "world first" is created. For the first time in the world, power grid laser obstacle remover with completely independent intellectual property rights successfully treats the hidden dangers of foreign body hanging lines in ultra-high-voltage lines.
It is reported that, up to now, this product has been put into use in Sichuan, Hunan, Anhui, Beijing, Shandong, Fujian, Jiangsu and other places, removing thread-drawing foreign bodies for more than 1,000 times, with an average consuming time of less than 5 minutes, combined with stable and reliable performance, it has been unanimously praised.
