Description

Technical Field

[0001] The present invention relates to the technical field of monitoring load-bearing tools for live working on high-voltage transmission lines, and in particular to a load-bearing tool for live working on high-voltage transmission lines and a method for using the tool. Background Art

[0002] High-voltage transmission lines require continuous maintenance during operation to ensure continuous and reliable power supply to the grid. While live-line work can avoid power outages, it poses a complex operating environment and high risks, primarily in the following areas:

[0003] 1. Blind spot in force monitoring: It is difficult to obtain real-time force data of traditional load-bearing tools (such as hanging hooks, screw rods, and insulating ropes) during operation. Once overloaded or the tool fails due to fatigue, it is easy to cause detachment or falling accidents.

[0004] 2. Insulation performance is difficult to evaluate online: Existing insulation tools can only be evaluated through periodic tests. Their leakage current and insulation performance lack real-time monitoring during on-site operations. Once the insulation ages or the surface is contaminated, it is very easy to cause the risk of electric shock.

[0005] 3. The impact of current fluctuations is not quantified: High-voltage lines are subject to load fluctuations, switching shocks, and other conditions. The instantaneous changes in conductor current have a direct impact on the safety of tools and operators, but traditional methods make it difficult to synchronously record and analyze them.

[0006] 4. Delayed early warning and decision-making: Existing monitoring systems rely heavily on manual inspections or post-event data analysis, failing to achieve online visualization of operational status and immediate early warning, making it difficult to address potential hazards in a timely manner.

[0007] Based on this, the present invention proposes a load-bearing tool for live working on high-voltage transmission lines and a method of using the tool to achieve multi-modal real-time monitoring of the tool's force, deformation, current and insulation status, and transmit the data to a wireless monitoring data receiver, helping operators and persons in charge to conduct online monitoring and risk warning of the entire live working process, thereby improving the safety and reliability of high-voltage live working.

3. The electrician on the tower secures the old insulator string, removes the old insulator string and connects it to the crossarm. The electrician on the tower controls the tail rope and works with the electrician on the ground to lower the replacement insulator to the ground. S4.

4. Lift and replace the new insulator. First, restore the cross-arm connection, then restore the conductor connection. Check that the insulator string pins are complete and aligned, and that the pins are in place. S4.

5. Loosen the screw rod, transfer the load to the new insulator string, and remove the screw rod and the load-bearing tools for live working on the high-voltage transmission line; S5, exit the electric field; The equipotential electrician shall withdraw from the electric field after confirming that the safety belt and shielding suit are properly connected; S6, lower tower; The electrician on the tower carries the insulating transfer rope down the tower.

10. The method for using a load-bearing tool for live working on a high-voltage transmission line according to claim 9, characterized in that: After step S6, the wireless monitoring data receiver automatically generates a table and a trend chart of the maximum value, minimum value, average value and alarm time point of this operation.
