"This line is the 'main artery' of power supply, connecting hefei No. 2 power plant and Screwdriver substation. Safe operation during high temperature and heavy load is extremely important!" Zhang chengxi said that before this year's peak summer, the center carried out a detailed special tour of the city's important transmission lines in advance, and promptly found and eliminated more than 500 hidden defects.
According to reports, the total length of the spiral up to 21 kilometers, along the road side extends to the distance of the invisible. If the traditional manual inspection is used, the staff should use telescopes and other equipment to go to each tower on foot for inspection. This will take at least a day, and there may be subtle pitfalls left behind.
"Since this year, we have made full use of the means of scientific and technological operation and maintenance, greatly improving the efficiency and making any defect 'impossible to escape'!" Under The operation of Zhang Chengxi, the uav flies steadily in the high altitude, and key parts of the line, such as porcelain bottles, are as clear as before. "Unlike other similar products on the market, this professional version of the drone can accurately locate, its monitoring error is only centimetres."
Currently, Hefei is in the process of a new round of large-scale construction. In order to eliminate unsafe offline construction behaviors, the city's power grid has set up "sky eyes", and 1000 sets of line image monitoring devices are used for 24-hour monitoring of important line channels. In case of off-line fire and unsafe work, it will report to the police in time and send a short message to the staff's mobile phone in the first time.
