Recently, a "laser cannon" to clean up the trees of the video went viral: due to the trees are too dense, affecting the operation of power equipment, a power company in Sichuan staff on the ground to operate a magical device. In an instant, thicker than the bowl mouth of the trees suddenly broke, the incision scorched black, very smooth. Netizens have exclaimed, "Is this the Six-Pulse Excalibur?"
Six Chakra Divine Sword is a fabrication of martial arts novels, "Laser Cannon" practical application does not have the same launch path and sound effects in the video, the entire process of clearing the obstacles is unlikely to be completed in an instant as in the video. In fact, the laser to clear obstacles to the application of technology has been a long time, the "laser cannon" used here is actually a "laser remote clearing instrument", is widely used in the tree clearing, hanging cleanup, line de-icing, unexploded ordnance destruction and other fields to ensure the safe operation of the power system Operation has made considerable contributions.
What are the advantages of laser obstacle clearance?
In January 2008, a once-in-a-century snow and ice disaster, so that the temperature in many areas of the South dipped below zero. At night, with the mixing of snow and ice freezing, thicker and thicker layers of ice wrapped, so that the transmission lines are overwhelmed have broken, and even power transmission towers are collapsed.
In order to ensure people's production and life, the Southern Power Grid organized power workers to repair lines in the most seriously affected mountainous areas of Hunan province, striving to let the railroad network resume operation in early February. Several power grid workers sacrificed their lives at their posts during the grueling rescue. In the end, the disaster caused more than 100 deaths and 151.65 billion yuan in direct economic losses.
Learning from the pain, after the disaster, the power sector also began to think of new reforms. In China as the "infrastructure monster", improve the power grid facilities at the same time, laser removal also gradually show their own advantages.
Traditionally clean up high-voltage line debris, it is often difficult to determine the line directly in contact with which debris, in order to ensure safety may have to blackout operations. As the laser has the advantage of contactless cutting, for similar trees, snow and ice such complex conditions of the clearance, do not need power grid personnel to personally board the trees, to avoid the corresponding safety hazards at the same time also protects the ecology of the trees. At the same time, the whole process is efficient and simple, the laser will not damage the power lines, without the need for power outages.
How to ensure accurate and safe?
Laser is known as the "fastest knife", "the most accurate ruler", "the brightest light", mention laser, we tend to think of industrial production, high-power operations, more than ten millimeters thick steel plate should be sounded! And break the scene, then the laser debarring whether there are safety hazards?
According to the R & D company - Sichuan Red Bank Base Intelligent Technology Co., Ltd. said that the laser clearing instrument is not for personal sale, the target group only for the power grid system. The grid system staff in the use of laser barrier removal instrument, need to follow multiple security verification procedures to start, the background of the product use time and place will make a unified monitoring. At the same time, the equipment has a relevant internal identification function, if found people or animals will stop the light. Before launching, after entering the password, there is a delay in launching and sound and light alarms, to further ensure the safety of the equipment.
What is the application potential?
Not only for tree branches, for other non-metallic foreign objects, laser clearing instrument can also come in handy.
Not long ago on December 6, the State Grid Changzhi Power Supply Company staff Sun Rui in the monitoring system found that a village high-voltage line hanging plastic film. Do not underestimate a small piece of plastic film, with it constantly fluttering with the wind, may be hooked up to make the circuit short-circuit, is a security risk of grid operation.
At 13:00 on the same day, "laser cannon" was mobilized to the scene, with a laser issued, ten minutes later, this plastic film was successfully broken down and removed.
In addition, Leshan Electric Power Bureau has also used the equipment in 3 minutes to cut the trunk diameter of 15 centimeters of the tree, Zhanjiang Electric Power Bureau also used 5 minutes to cut the trunk diameter of 17 centimeters of the tree. (The fact that the laser operation lasted for such a long period of time was also to further ensure safety)
By the end of 2020, the total length of China's power grid had reached about 16.8 million kilometers, while the total length of ultra-high voltage transmission lines exceeded 4.7 million kilometers. From the roof of the world to the deep valleys and rift valley, every inch of the circuit, are hosted on one side of the people's food, clothing, housing and transportation needs, are indispensable arteries of the national economy. With the continuous application of laser clearing in the power grid system, its high efficiency and safety, without the need to power off the application of the advantages will be more obvious.
