220kv live work with carbon fiber board big knife card fixture

Abstract

The invention provides a 220kV live work with a carbon fiber plate big knife clamp, including a front clamp, a rear clamp, an insulating pull rod and a wire tensioner, the insulation pull rod is connected with the wire tightener, and the first clamp body and the second clamp body use carbon fiber The carbon fiber sheet includes at least two carbon fiber cloth layers and at least one carbon fiber filament layer, the carbon fiber filament layer is located between the two carbon fiber cloth layers, and the carbon fiber cloth layer is one layer of longitudinal carbon fiber and transverse carbon fiber. The vertical carbon fiber and the horizontal carbon fiber have the same fiber width, and the carbon fiber layer is bidirectionally interwoven with carbon fiber, and the carbon fiber cloth layer and the carbon fiber layer are impregnated with a binder. Strong durability, no rust, can be used in high acid, alkali, salt and atmospheric corrosion environment, also has the advantages of high fatigue resistance, wear resistance, anti-aging and so on.

Description

technical field [0001] The invention relates to a tool for high-voltage live work, in particular to a carbon fiber board machete clamp for 220kV live work. Background technique [0002] Since the birth of new China, my country's electric power industry has developed rapidly. Since the beginning of the 21st century, it has ranked second in the world, and the maintenance work of various voltage levels has increased greatly. The live work method has become an important method for power grid enterprises to effectively improve the reliability of power supply and meet the growing material and cultural needs of the country and the people. One of the technical means is widely used in China Southern Power Grid, and the great economic and social benefits it brings have been proven in practice. At present, the work tools, especially the clamps, are mostly made of metal materials such as steel and aluminum alloy, which is contrary to the needs of my country to build an environment-frie...
