Drone Line in the Snow

On January 7th, the first snowfall of 2020 went down to the third day. Under the special temperature and humidity conditions in recent days, some transmission lines in Jincheng have experienced icing conditions that have not been encountered for many years, which has put a lot of pressure on the security of the power grid.

Jincheng Power Supply Company's transmission and transportation inspection professionals embarked on a special tour of the transmission line. At the 110-13 volt Putian Line 12-13 # pole tower, the power transmission maintenance class will conduct the first snow drone patrol line.

Near noon, the snow was getting smaller, but the fog was still there. In the white wilderness, only a few figures in red and blue work clothes and hard hats were particularly clear. After exploring the location and taking out the drone, "Captain" Wang Meng carefully inspected the various parts of the machine to check the remote control and power. We discussed the flight route together, and the drone roared and flew up.

The reporter learned that "Captain" and "Flyer" are different levels of drone driver qualifications, like "A" and "C" for car drivers. The "captain" can operate the drone for over-the-horizon flight. Currently, only Wang Meng is the only "captain" in the power transmission and transportation inspection profession. He is the authority when the drone patrols the line.

Along the Putian Line, drones fly higher and higher, and fly farther and farther. Wang Meng and squad leader Gao Huiyong stared nervously at the monitor screen in their hands. From time to time, Wang Meng fine-tuned the flight height and position to hover the machine above the # 12 tower.

"... I can't see clearly, go down a bit." "The wires here are covered with ice and very thin."

The biggest role of the drone is to closely check the thickness of the icing wire, whether there is a galloping phenomenon, and whether the hardware has abrasion and collision. The images returned in real time are very clear, and they will also be stored. After being returned to the office, they will be exported for further research, providing first-hand reference materials for the icing of the line.

"You stood tall and slipped carefully," reminded Master Li Qiang, who was in charge of supervision.

When the drone flew back, there was 30% of power left. The two of them helped to get down from the snow slope and their feet slipped. They didn't care about their frozen hands, they checked the drone for the first time. Wang Meng pulled out the towel and carefully wiped off the snow on the flying platform.

The time has passed at 1 noon, and the line in the snow came to an end. The off-road vehicle made brisk ruts in the thick snow, and the power supply staff embarked on the return journey with a smile.
