The power inspection work has always been the focus of the State Grid Corporation of the current high-voltage transmission line operation and maintenance, management mode, and routine operation methods. The work of electric power inspectors is labor-intensive and tolerates problems such as links and climate influences, resulting in low work efficiency and potential safety hazards.
The emergence and development of electric power inspection drones effectively improve the efficiency of electric power inspectors, reduce the work intensity, and exclude the long-term high-altitude operations, the environment, the climate brought about by the security risks, and other problems. And the drone patrol has the advantages of low manufacturing cost, low flight cost, flight control personnel safety, mobility and flexibility, functional diversity, fast task unfolding speed, over-the-horizon autopilot, etc. UAV inspection can be divided into infrared and visible light inspection, which can be the whole video and photo. Combining a variety of equipment to inspect and record the lines by various means greatly improves the technical content of transmission line inspections and shows its superiority in places that are difficult to patrol manually, such as mountains and large ridges or UHV transmission lines. It was a huge leap inline inspection.
Line inspection is a work that power companies and enterprises must do every day, mainly to check whether there are problems with the circuit. If there are problems, they need to be dealt with in time to avoid causing greater disasters. However, it is very troublesome to rely solely on the workforce to patrol the line, and a lot of time and energy will be wasted. At this time, power line patrol drones can be invested. So what are the main advantages of this drone?
1. It is not restricted by the terrain environment and has high efficiency.
The environment and terrain limit the traditional manual power line inspection method, and the efficiency is low. Usually, the UAV can complete the task of 1 hour in 15 minutes for a voyage. Especially in steep terrain, the advantages of UAVs are more obvious.
2. Ensure the safety of personnel.
Traditional artificial line patrols usually face the danger of being attacked by wild animals and insects. In emergencies such as flash floods and earthquake disasters, life and safety may even be endangered. Unmanned aerial vehicles(UAV) can conduct surveys and emergency investigations on potential hazards of the line, such as the collapse of the tower foundation, without being affected by the road conditions.
3. Low cost and high accuracy.
Compared to helicopter patrol, UAVs have advantages and costs, and personnel can carry visible light, infrared thermal imaging, and ultraviolet imaging equipment for all-round observation of the line. Drones can also perform fixed-point hovering and more detailed inspection of the line. Drones with built-in GPS positioning and navigation systems can also eliminate the risk of disappearance and minimize risk.
UAVs are lightweight and loaded with advanced aerial survey systems, which are less costly and much more convenient than human-crewed aircraft and helicopters. Generally, only two staff can complete the task, can be remotely shot on the transmission conductor, gold, insulators, and tower corrosion and fouling, line corridors, and other conditions to monitor, and can obtain a full range of transmission line image data, instead of artificial climbing inspection.
In response to the pain points of transmission line channel inspection, JOUAV adopts vertical take-off and landing(VTOL) and fixed-wing cruise to solve the problems of inconvenience and low reliability of traditional fixed-wing UAVs. According to the preset route, it can easily reach areas out of reach and adjust the position and height according to the terrain coordinates to complete the line patrol task. At the same time, a variety of solutions have been proposed for power channel inspections, including routine inspections of transmission lines, oblique photography and tree barrier ranging inspections, lidar inspections, and real-time monitoring inspections.
