A rescue method for people working at heights on power transmission lines after the wires fall

Abstract

The invention discloses a rescue method for workers who work at heights on a power transmission line after the wires fall, which solves the problems that the trapped workers are prone to suspension syndrome and life risks in the prior art, and has the advantages of preventing the trapped workers from quickly The beneficial effect of getting rid of the danger is as follows: a rescue method for workers who work at heights on power transmission lines after the wires fall. An annular ring is set at the bottom of the pedal, and the person's feet are placed in the annular ring for support, so that the person can be supported; take out the throwing bag and the traction rope, and tie the traction rope to the safety belt; Conductor throwing, so that the throwing bag guides the traction rope to bypass the conductor, and the operator climbs up to the conductor through the short safety rope.

Description

Technical field[0001]The present invention relates to the field of transmission lines, in particular, to a rescue method behind a wire fall of high-altitude operation personnel in transmission lines.Background technique[0002]The installation construction, operation and maintenance and repair of the transmission line requires the operator to go up and down the tower, on the rod tower, wire, and insulator. The transmission line operation has the characteristics of high-altitude, more complex, more complicated, more manual operation, high labor intensity, high dangerous, and high rescue difficulties. At present, when operators are homework on wires, they mainly rely on all-round seat belts and backups. Protect rope for individual protection, there is a risk of falling from a high risk, which belongs to high risk operations. Especially the ultra-high pressure of 500kV and above voltage level, it is easy to fall from high-voltage transmission line operation, while the operator has not su...

AI Technical Summary

Problems solved by technology

The operation of transmission lines has the characteristics of large amount of high-altitude operations, complex and changeable environment, many manual operations, high labor intensity, high degree of danger, and difficult rescue. At present, when operators work on wires, they mainly rely on all-round safety belts and backup The protection rope is used for personal protection, and there is a risk of falling from a high place, which is a high-risk operation

In particular, ultra-high voltage and ultra-high voltage transmission lines with a voltage level of 500kV and above are prone to fall from high places during operation, and the workers are not supported after falling, and are suspended by seat belts, and trapped workers are suspended in the air by seat belts for a long time Suspension trauma (seat belt suspension syndrome) will occur and gradually lose consciousness, coupled with factors such as fear, impact injury and no self-rescue ability, the rescue time is very urgent

In addition, the rescue on the existing transmission lines and transmission towers often requires a power outage for rescue, so once the emergency stop operation due to rescue, it will cause a large amount of transmission power loss (power outage) or a large number of load transfers, causing damage to the grid structure and seriously affecting The safe and stable operation of the power grid may cause large-scale power outages in the power grid, which will have a great impact on normal production and living order, and endanger social harmony, security and stability.
