Abstract

The invention relates to a 1000-Kv tension-resistant horizontal insulator charged exchange device. The device comprises a large-bypass stressing system, wherein the large-bypass stressing system comprises a tension-resistant front clamp and a tension-resistant rear clamp; an insulating pull bar is arranged between the tension-resistant front clamp and the tension-resistant rear clamp; a wire-tensioning device is arranged at the end head of the insulating pull bar; and a functional opening is formed on the tension-resistant front clamp. The invention provides the tension-resistant horizontal insulator charged exchange device, which is convenient to operate, exchanges devices simply and is safe and reliable to use.

Description

Technical field [0001] The invention belongs to the technical field of live working on ultra-high voltage transmission lines, and relates to a strain-resistant horizontal insulator live replacement device, in particular to a 1000kV ultra-high voltage transmission line strain-resistant horizontal insulator replacement device. Background technique [0002] The 1000kV UHV power grid is currently the highest voltage power grid currently in commercial operation in my country and the world. The power grid from Shanxi Jinsoutheast to Hubei Jingmen Power Grid was completed and put into operation in 2008, and the northwest to North China and the southwest to Central China are under construction. Relying on these UHV grids to realize the conversion and deployment of super-capacity energy to meet the energy demand of the rapid development of my country's socialist construction. [0003] The 1000kV ultra-high voltage power grid has a decisive impact on the security of the power grid from the m...
