High-altitude rescue method under hot-line work

Abstract

The invention discloses a high-altitude rescue method under hot-line work, and belongs to the technical field of safety rescue methods. The high-altitude rescue method comprises the following steps that S1, a rescue worker climbs a tower, enters a power transmission line in an equipotential mode and conveys rescue equipment to the position above a trapped person; S2, an operation protection station is arranged above the trapped person through a high-altitude rescue combined device; S3, rescue is carried out through a descent control device in the high-altitude rescue combined device; and S4, rescue and personnel evacuation are completed, the descent control device is an insulating descent control device capable of achieving one-way self-locking hovering in a hand cranking mode. The rescuemethod is determined according to the physical condition of the trapped personnel, rescue can be achieved no matter how the trapped personnel are, operation is easy and convenient, and rescue time issaved.

Description

【Technical field】 [0001] The invention relates to the technical field of safe rescue methods, in particular to a high-altitude rescue method under live-line work. 【Background technique】 [0002] At present, the high-altitude rescue method of transmission lines is to rescue in the event of a power outage, which takes a long time, and a long-term power outage will cause a large amount of transmission power loss or a large number of load transfers, damage the grid structure, seriously affect the safe and stable operation of the grid, and cause Large-scale power outages in the power grid affect people's quality of life and cause serious economic losses to merchants, power consumers, and enterprises. Therefore, non-stop operation has become a trend, and research on live rescue has become a top priority.

[0002] At present, the high-altitude rescue method of transmission lines is to rescue in the event of a power outage, which takes a long time, and a long-term power outage will cause a large amount of transmission power loss or a large number of load transfers, damage the grid structure, seriously affect the safe and stable operation of the grid, and cause Large-scale power outages in the power grid affect people's quality of life and cause serious economic losses to merchants, power consumers, and enterprises. Therefore, non-stop operation has become a trend, and research on live rescue has become a top priority.

[0003] Live work can be divided into three categories according to the relationship between the human body and the charged body: equipotential work, ground potential work and intermediate potential work. Dangerous currents flow through and endanger personal safety. Therefore, all workers entering high electric fields should wear a complete set of qualified shielding clothing, including underwear, shoes and socks, hats and gloves. The electrical connection is good, and the resistance between the farthest ends should not be greater than 20Ω, so that an equipotential body is formed on the surface of the human body. The equipotential operation is highly dangerous, labor-intensive, and there is a high risk of rescue after an accidental fall. However, there is no perfect electrification system in China. rescue method
