The power transmission is realized by using a transformer to boost the electric energy generated by a generator and then connecting the electric energy to a power transmission line through control equipment such as a breaker and the like. According to the structural form, the power transmission line is divided into an overhead power transmission line and a cable line. The overhead transmission line consists of a line tower, a lead, an insulator, a line hardware fitting, a stay wire, a tower foundation, a grounding device and the like and is erected on the ground. Power transmission is classified into ac power transmission and dc power transmission according to the nature of the transmitted current.
Usually, the cables of the towers of the transmission line are arranged in the field. In low-temperature rain and snow weather and cold weather, due to high humidity, a large amount of water vapor is condensed on the surface of the wire to cause re-icing, so that the freezing disaster of the power system is easily caused. When ice is recovered, the tension on two sides of the rod is unbalanced, and the falling of the rod caused by the breaking impact load of the lead can occur; frozen electric wires can shrink when cooled, wind blows to cause vibration, the electric wires can be broken sometimes because of unsmooth heavy load, and even if the continuous galloping time is too long, the wires, the tower poles, the insulators, the hardware fittings and the like can be subjected to unbalanced impact to cause fatigue damage. The power transmission line pole (tower) falling, line breaking and tripping accidents caused by ice coating and waving can cause great damage to the power transmission line of the power system, and further threaten the safe and stable operation of a power grid and the reliability of the operation of a power supply system.
Generally, the height of a tower of a power transmission line is high, the power transmission line spans between two towers, the span is large, sometimes, a mountain stream exists between the two towers, and geographical factors such as a cliff and the like which are not beneficial to inspection are included. This brings great inconvenience to daily inspection and special inspection. If the manual inspection and special inspection are adopted, the tower can only be climbed manually for quality inspection, thus bringing great danger to inspection personnel and being not beneficial to the operation of a daily power transmission system.
High tension transmission line arranges in the field, all need overhaul each year, each item work such as salvage, staff's power failure during operation then need install the earthing wire temporarily in the circuit each side, then demolish after the work, then report as value scheduling personnel, then often because various reasons have the staff to miss demolish the earth connection or the circuit has work and not in time inform the dispatch, lead to the circuit to take the earth connection and the vicious maloperation incident of closing a floodgate. Meanwhile, after the circuit is not successfully tripped and coincided, a dispatcher can forcibly send the signal once according to a dispatching rule, if the high-voltage circuit is disconnected or the high-voltage circuit is grounded, the signal can be tripped again, huge impact current can impact and damage the whole circuit and station end equipment, and even cause misoperation or override action of protection, so that the accident range is enlarged. Some prior arts disclose a method for inspection without manually climbing to a tower, such as infrared data, video data, visible light image data and laser point cloud data acquired by collecting a target object on a power transmission line based on an unmanned aerial vehicle; the infrared data, the video data, the visible light image data and the laser point cloud data which are acquired after the target object on the power transmission line is acquired by the unmanned aerial vehicle are acquired, and the infrared data, the video data, the visible light image data and the laser point cloud data which are registered are displayed according to the acquired display instruction, so that three-dimensional visual management can be performed, and more data support is provided for power transmission line management and maintenance. The visual detection of the routing inspection power transmission line is realized. Only the problem of being able to see the transmission line is solved. However, in the power transmission line, the number of positions to be inspected is large, the environment is complex, the positions to be detected have specific requirements, sometimes, the power transmission line detection device needs to be well controlled during inspection, the specified position of the power transmission line can be detected, and the purpose of detection cannot be achieved if the specified position is not detected. Sometimes, the power transmission line is required to enter narrow spaces such as deep wells, tunnels and caves for detection.
With the continuous acceleration of industrialization and urbanization, the power demand continuously increases, and a strong and reliable modern large power grid has irreplaceable effects on guaranteeing national energy safety and optimizing energy configuration in a larger range. The intelligent power grid with the characteristics of informatization, digitization and automation is a guarantee of safe, reliable and efficient power transmission, is the direction of power science development, and is particularly important for monitoring the power grid. The power transmission line serving as a power transmission link has the characteristics of large dispersity, long distance, difficulty in inspection and maintenance and the like, so that remote monitoring of the power transmission line becomes urgent work.
