On the same day, Xiong Feng, a technician of the third shift of the State Grid Wuhan Power Supply Company's power transmission and inspection branch, and his colleagues Zhang Qiang and Li Chang came here to inspect the 110 thousand volt Dai iron line.
Xiong Feng told reporters that his team is responsible for the daily inspection of a total of 106 lines in the central urban area of Hankou and Dongxihu District, with a total length of 610 kilometers.
In the recent Spring Festival, low temperature rain and snow have been superimposed, and the hidden dangers related to the important routes of the Spring Festival transportation capacity should be particularly detailed. Xiong Feng told reporters that the Dai Tie Line is nearly 6 kilometers long, spanning the Beijing-Guangzhou Line, which is an important support for the power supply of railway trains. Recently, they have focused on the 110 thousand volt Dai Iron Line, German Railway Line and other key lines related to railway power supply to increase the inspection efforts, from once every two weeks to once every 3 days, and the team members can patrol the line every day The length of the line can reach 30 kilometers.

On the ground covered with ice and snow, the team members carried equipment and walked cautiously to prepare for drone inspection in an open field. Immediately, the drone took off into the air, and under the control of Zhang Qiang, it slowly approached the top of the tower, hovering precisely at the components and connections, and the team members carefully checked it on the flight controller. "Focus on checking whether the insulator is seriously iced, whether there is abnormal fracture of the line and other hidden dangers. At the same time, Li Chang** walked under the road, used a telescope to check the important parts, and found a suspicious problem, so he used a drone to approach and review.
There are no significant anomalies in this paragraph. 20 minutes later, Zhang emphasized that he returned to the drone, and everyone packed up the equipment and returned to the car, headed towards Daijiashan, to the next point, and continued to inspect. At 5 o'clock in the afternoon of the same day, at the other end of the ** road, Daijiashan substation, they ended the inspection of the line.

Since the current round of low temperature and cold wave weather in Wuhan, Xiong Feng and his colleagues have been on duty all day, braving low temperature, rain and snow, and found and eliminated hidden dangers such as icing of multiple wires and insulators during inspections, which effectively guaranteed the power supply of the Spring Festival transportation capacity.
It's a test of faith and patience. Xiong Feng said that the UAV inspection has high requirements for control accuracy, and the aircraft must maintain a safe distance of more than 1 meter from the cable and equipment. At the same time, the inspection line often crosses the mountains and wastelands, and it is difficult to walk and the road is arduous, which is greatly affected by the weather, "the worse the weather, the more you need to rush to the front line and go all out to ensure the safety of power supply during the Spring Festival and the Spring Festival."
