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. ... [Detail]

Bird's nests are often built on power grid rail towers. Branches, grass stems, wire and so on held by birds easily trigger the short connection of the charged body, resulting in tripping, and even burning the equipment. It will cause the power equipment power failure of catenary machines, causing a great impact on the normal transmission and distribution power grid. In particular, birds peck insulator string damage, and bird feces cause insulator string flashing and other circumstances, which will cause more serious power safety accidents. ... [Detail]
