At noon on August 7, the Huangshi Meteorological Observatory issued a high -temperature red warning. The maximum temperatures of Huangshi City and Daeye and Yangxin will rise to above 40 ° C. That night, Huangshi Power Grid has a maximum load of 2.507 million kilowatts, which is the second time this year reached a record high. At high temperature, high -voltage transmission lines are the same as people, which may be "heat stroke". In order to ensure the normal electricity consumption of residents in the hot summer weather, the State Grid Huangshi Power Supply Company's Inspection and Transportation Inspection Branch used sharp technology to conduct a "physical examination" of high -voltage transmission lines.

"With these two things, you don't have to climb up the mountain to detect it." On the morning of the same day, the operation and maintenance worker of the State Grid Huangshi Power Supply Company's Inspection and Transportation Inspection Branch came to Daye Luoqiao to measure the high -voltage transmission line. Chen Zhulin, deputy squad leader of the class, introduced that at the beginning, he rely on manual climbing to the tower to measure the temperature, especially when the summer high temperature weather climbed up the hillside at noon, the surface temperature was as high as 70 ° C, and the dense jungle made people breathe. It takes more than half an hour to go up and down. Later, with the development of science and technology, there was an infrared armal gun, but it also needed to walk to the bottom of the tower to measure temperature. "With these pointed technology, it is much more convenient now." Chen Zhulin pointed at the infrared temperature guns around him and the drone equipped with infrared devices told Jimu Journalists that using these two tools can be tens of meters in a few minutes. The distance tower is tested.

"220 kV Magnetic Ping No. 2 Tower 2, A phase left front line clip 38 ° C, B phase right rear thread clip 41 ° C." After the drone was launched to detect the tower, Chen Zhulin reported to his colleagues. temperature.

"The temperature of the No. 3 Tower A phase clip has an abnormal temperature, which has reached 79 °. We immediately go up the mountain and use an infrared temperature gun for reinstallation." The ground temperature at noon is about 40 ° C. Later, he carried the toolkit with his colleagues and started walking up the mountain. Twenty minutes later, they came to the top of the mountain and began to use the warm gun for re -testing. "The temperature of the wire clip has reached 75 ° C, which is a serious defect, and exceeding 130 ° C is critical defect. After returning, we study the processing plan." Chen Zhulin introduced that the use of drones for temperature measurement is that Huangshi Power Transmission Company recently introduced the recent introduction The black technology only needs to fly the drone to 3 meters from the wire to collect the real -time temperature of the wire clip. At the same time, according to the different colors on the screen, you can determine whether the line is abnormal.

"In the past, we needed to travel to the tower in front of our temperature. Now we have drones. We can measure the lines by several hundred meters." Chen Zhulin said.

It is understood that since July, Huangshi Power Transmission Company has conducted three full coverage of 220 kV transmission lines in the area. A total of 3 critical defects were found, 16 serious defects, 2 times with power discharge, and power outage and discharge of 1 1 time. Secondly, the safety and reliability of the power grid during the peak summer period was effectively guaranteed, laying a solid foundation for the cool summer summer in the hot summer.
