Description

technical field [0001] The invention relates to the field of high-voltage transmission lines, in particular to a three-dimensional visualized intelligent monitoring system for ultra-high voltage transmission lines. Background technique [0002] At present, the existing 500kV power grid is often constructed with a Japanese-shaped double-ring network. As an artificial structure of UHV power lines located in three-dimensional geographical space, the line distance is generally very long, and the geographical environment of the passing area is relatively complicated. , how to safely and effectively monitor and manage UHV transmission lines to ensure the safe operation of the power grid is very important. [0003] Traditional monitoring methods cannot accurately monitor UHV transmission line data (iron towers, wire sags, insulator strings, jumpers, etc.), nor can they link transmission line equipment and environmental conditions such as line corridor topography and landforms for c...
