Laser obstacle remover de-icing site
The accident caused by ice covering of overhead transmission line is very harmful considering the current situation of ice covering of transmission line at home and abroad. There are many solutions for prevention, melting and de-icing that have been explored at home and abroad. Through research and discussion, the heat transfer and energy of wire icing were analyzed, and a variety of lasers were used for laser de-icing (ice-removing) experiments, and the de-icing situation of CO2 laser was compared. The method, research direction and prospect of laser de-icing has also proposed.
There are various types of icing on the transmission lines, including wet snow, mixed glaze, fog glaze, rain glaze, frozen fog icing and freezing rain icing, etc. The main meteorological factors affecting the icing of the lines are wind, temperature and air humidity. If the transmission line is covered with ice, it may cause icing flashover; if it is heavy, it will cause towers (poles) falling, lines breaking, and even destroy the power grid. We can make detailed emergency plans for line operation through ice-covering observation and calculation. The ice-covering data after long-term observation is an important basis for the division of ice areas and has important guiding significance for the design, operation and maintenance of overhead transmission lines in the future.
