Power transmission lines are exposed outdoors all year round. It is inevitable that foreign objects such as plastic sheets, kites, and dead branches will get entangled on the conductors. This not only affects the normal operation of the lines but also may cause safety hazards such as short circuits and tripping. What should be done?
Removing them by manual climbing is not only troublesome and laborious but also involves huge risks such as falling from heights and electric shock, with extremely low safety. Now, whenever possible, laser obstacle removal devices are used. They can be operated remotely from the ground, avoiding risks like falling from heights and electric shock, and efficiently completing the obstacle removal. It's just too convenient.
However, many people are still concerned: what if the laser burns the power lines when clearing obstacles? Here's the clarification: only when the laser clearing device is used in violation of regulations, such as deliberately shining the laser on the power lines for a long time or starting the equipment without precise positioning, is there a possibility of causing slight wear on the surface of the lines. But as long as the operation is standardized, such problems can be completely avoided.
Under normal and standardized usage, the laser of Guangxi Hizhao Technology's HIZ-NT-QZY overhead line laser obstacle removal device will never burn the transmission lines. The core lies in its precise technical design and strict safety control. The specific reasons are as follows:
1. Precise laser parameter matching: The laser wavelength and power of the equipment have been strictly debugged. It will only produce thermal effects on the obstacles to be cleared, such as dead branches, tree trunks, and non-metallic hanging objects (plastic, kites), thereby achieving precise cutting and removal. The core material of the transmission line is steel-cored aluminum stranded wire, which inherently has the characteristics of high-temperature resistance and laser loss resistance. The laser energy will not cause any damage such as scorching or strand breakage to it at all.
2. Intelligent Positioning and Control: The equipment is equipped with a focusable machine vision magnification system, which can accurately lock onto the obstacle clearance target and effectively prevent the laser from mistakenly irradiating the main body of the transmission line. It also has a power adjustment function, allowing for flexible adjustment of laser energy based on the clearance distance and target size, ensuring that the laser only acts on the obstacles and does not affect the normal operation of the line.
3. Robust safety protection mechanism: The equipment is equipped with multiple safety monitoring modules. Once it detects that the laser deviates from the target or approaches the core part of the transmission line, it will automatically trigger a shutdown protection, further eliminating the risk of line damage caused by misoperation and comprehensively ensuring the safety of the transmission line.
