On August 23, the State Grid Chengdu Power Supply Company launched the first remotely-disconnected foreign body cleaner in the power grid called “Power Laser Cannon” in Wenjiang to clean up the tree barrier in 3 minutes, and quickly eliminated nearly 200,000 residents from power outages. According to reports, the green laser pointer laser cannon was introduced by the State Grid Chengdu Power Supply Company this year. After several previous tests, it was officially put into use for the first time yesterday.
It is reported that there are 56 hidden power lines in Chengdu, which are less than 3 meters away from trees and bamboos, which may trigger regional power outages at any time. As a national flower and tree base, Wenjiang has many hidden dangers in the area under the line. It is a “hardest hit” and “exclusive” 19 hidden dangers. In the event of a 220 kV overhead line, nearly 200,000 residents of Wenjiang will have no electricity available, so the tree barrier must be removed.
Yesterday, the staff patrolled the first and second lines of 220 kV fish in Wenjiang District and Shengzhen, where the hidden dangers were discovered. The drones were used to accurately measure the distance between the overhead lines and the branches – only 1.9 meters! It is understood that this green laser pointer drone was only received on July 15 this year.
The staff first opened a large black box, and took out a camera-like launching instrument from the inside. After the screen was calibrated to remove the obstacle, the green laser would align with the branches that needed to be removed, and the green laser pointer became stronger. The bigger the cigarette is, the lower end of the branch begins to smoke. With an open flame, in less than 3 minutes, the branch is carbonized and falls from the top of the tree. The entire clearing work is completed smoothly.
Yang Fan, deputy director of the transmission and transportation inspection area, said that now the grid remote foreign object remover removes the obstacles, the first time is less, the maximum temperature of the laser can reach 390 ° C, generally only about 3 minutes to eliminate obstacles, kites, etc. It only takes a few seconds. Second is safety, all items within 200 meters can be eliminated through it. Finally, because it is a visual green laser pointer, night clearance is completely unnecessary.
