[0010] There are three types of damage that ice can cause to power transmission lines. The first is a small amount of ice. The circular ice on the conductor is not evenly covered on the conductor. It may form an ellipse or other shapes, forming a windward surface in the atmosphere. When the wind angle and the windward angle of the ice are right, the conductor will dance. The second situation is flashover. The structure is not damaged, but its insulation is lost. Once it flashes, the electricity cannot be sent out. The third and most common type is that the entire structure collapses due to excessive vertical load.

[0011] For areas with cold and humid weather, ice on conductors seriously affects the safe operation of transmission lines. Ice on conductors brings harm to production safety, increases the workload of maintenance, and increases corporate costs. Therefore, effectively avoiding and preventing the harm caused by ice disasters to transmission lines is a topic that power and cable companies must face. Only by taking multiple measures can we actively prevent and control ice disasters in power grids.

[0012] However, the accuracy and intelligence level of ice detection on power transmission lines in the existing technology cannot meet the current needs, resulting in false alarms or untimely alarms, which poses a hidden danger to the safe operation of power transmission lines.
