Description

A wire tightening method for electric power construction

technical field

The invention relates to the technical field of electric power construction equipment, in particular to a wire tightening method for electric power construction.

Background technique

In recent years, in order to solve the "stuck neck" and "low voltage" problems of the power grid and meet the increasing electricity demand of the majority of users, the State Grid has launched various power grid upgrading and reconstruction projects.

Electricity is an energy source powered by electrical energy. Invented in the 1870s, the invention and application of electricity set off the second industrialization climax. It has become one of the three scientific and technological revolutions in the world since the 18th century in human history. Since then, technology has changed people's lives. The large-scale power system that appeared in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. It converts the primary energy of nature into electricity through mechanical energy devices, and then supplies electricity to various users through power transmission, transformation and distribution.

The transmission of electric energy, together with power transformation, power distribution, and power consumption, constitutes the overall function of the power system. Through power transmission, power plants and load centers that are far apart (up to thousands of kilometers) are connected, so that the development and utilization of electric energy go beyond geographical restrictions.

Transmission lines can be divided into overhead transmission lines and underground transmission lines according to their structural forms. The former consists of line towers, wires, insulators, etc., and is erected on the ground; the latter mainly uses cables and is laid underground (or underwater).

During the construction of overhead transmission lines, it is inevitable to use cable pay-off and take-up equipment.

Cable pay-off and take-up equipment is generally used in the production and construction of various cables. Through pay-off, the wire on the reel can be evenly and straightly transported to the winding mechanism for processing. The traditional pay-off is mainly through The motor drives the wire reel to rotate to pay off the wire. Because the size of the wire reel is different, during the continuous pay-off process of the wire reel, as the diameter of the coil gradually becomes smaller, the length of the wire released by one rotation of the wire reel is different, and the release cannot be guaranteed. The uniform speed pay-off of the wire machine, and during the pay-off process, due to the change of the speed of the wire reel drive device and the speed of the drive device of the winding mechanism, the tension of the wire will change, which will easily cause excessive wire bundle accumulation Or the phenomenon of jamming due to too few wire harnesses will affect the cutting of the later wire harnesses.

Similarly, similar problems also exist in the line take-up process.

in addition. In the wiring process of electric power construction, manpower or large-scale equipment are generally used to lay out the wires. Sometimes the construction site environment is narrow, there are many people or large-scale equipment cannot be deployed, or safety accidents are prone to occur during the process of tightening and feeding wires.
