At present, the transmission lines above 35kV in the overhead lines of the power system in various cities are all bare wires, and there are as many as a thousand foreign objects hanging on the wire every year within a length of thousands of kilometers.
The traditional treatment method requires line blackouts or live work, but line blackouts reduce the reliability of power grid power supply, increase the risk of regional blackouts, and cause greater economic losses and negative social impacts.
In the past, the main method of hanging foreign objects or removing harmful trees was to rely on personnel to approach or enter high-voltage electric fields, directly or indirectly contact charged objects, remove falling objects, and endanger trees.
