Research and Application of Special Tools for Installing Online Icing Monitoring Devices for 500 kV Compact Transmission Lines While Live
In power systems,icing disasters on transmission lines can cause pole collapses,wire breakages,and power outages,resulting in huge losses.Preventing icing disasters on transmission lines and conducting early monitoring is currently the best method.At this stage,mainly by installing an online icing monitoring device for transmission lines,real-time on-site icing data is collected,the on-site situation is analyzed,and deicing measures are taken in a timely manner to ensure the safe and stable operation of transmission lines during freezing periods.The core point of installing an online icing monitoring device for 500 kV compact transmission lines is to replace the U-shaped ring fittings of the original line with the load-bearing data sensor of this device.Generally,a special screw rod,fixture,and insulating pull plate are used to connect the lifting hook to tighten the conductor.After transferring the load of the insulator string,the U-shaped ring fitting is removed and then replaced with the load-bearing data sensor of the icing monitoring device.500 kV compact transmission lines mostly use composite insulators and are connected to conductors in a"V"shape.
