Affected by a new round of cold wave, rare freezing rain broke into the Yangtze River Delta, most of the areas in Zhejiang thunderstorms, hail, gusty winds, high-altitude mountainous areas continue to maintain the temperature below zero degrees Celsius, resulting in the existence of ice-covered power lines and equipment potential risks.
In order to protect the safe and stable operation of the line, in recent days, the State Grid Zhejiang Electric Power and rain, snow and ice weather racing, continued to carry out anti-icing and anti-icing initiatives. In Huzhou, Zhejiang Province, Hangzhou, power transmission operation and maintenance personnel to carry out de-icing operations using FC30 large carrier drone, which is also Zhejiang Province, the use of carrier drones to carry out transmission line de-icing work. In addition, State Grid Zhejiang Electric Power also timely ice-covered lines to carry out DC ice melting work, to protect the residents of stable power supply.
The use of drone de-icing and DC ice melting, effectively eliminating the line ice-covering hazards, what is the difference between the two? And what are the characteristics? The following DINSEE SMART to popularize for you.
Drone de-icing
Drone de-icing is the use of drones lifting de-icing stick ascending, by two flyers to complete, a flyer driving a small drone to observe the de-icing position auxiliary command, another flyer is responsible for the implementation of de-icing tasks, in determining the flight altitude, the drone accelerated forward to drive de-icing stick forward fling, can accurately impact the ice layer, so that the ice layer is broken and fall off. The drone de-icing method can make the snow and ice fall quickly, not only do not need to blackout, but also in the early stage of ice cover can effectively curb the rapid growth of ice cover speed, safe and efficient.
DC Ice Melting
DC ice melting is by applying direct current to the line, so that the line heat to eliminate the ice, with high efficiency, wide range of use, high safety factor advantages.
It is understood that during the current round of cold wave, State Grid Zhejiang Electric Power comprehensive organization to carry out transmission, substation and distribution equipment cold wave special patrol. As of February 25, the province's total number of power facilities special patrol personnel more than 9,600 people, special patrol vehicles more than 5,100 times, the key areas, key channels and key equipment for rain, snow and ice hidden trouble again, the responsibility to re-implement. At the same time, the company stationed 13 ice observation stations, 23 ice observation points, covering 50 lines, equipped with 13 sets of transmission, 9 sets of distribution DC ice melting device. Nearly 8,000 repair personnel stick to the front line, fully guarding the safe operation of the power grid and reliable power supply to users.
