[0002] Pollution flashover has long threatened the safe and stable operation of power systems. Traditional methods of regular line cleaning are time-consuming and labor-intensive, and lack real-time detection capabilities. An intelligent pollution monitoring and early warning system monitors the contamination status of insulators in real time and uses this data to determine whether insulators require cleaning, reducing unnecessary cleaning and improving efficiency. The intelligent pollution monitoring and early warning system requires the installation of drainage rings on high-voltage insulators to collect the pollution flashover voltage of the monitored insulators.

[0003] Existing drain rings are manually installed close to high-voltage insulators, posing a significant threat to the safety of installers. Therefore, a device that can remotely install drain rings is designed to ensure the safety of installers and improve installation convenience.
