Problems solved by technology

[0004] With the continuous expansion of the scale of the power grid, the situation of wire galloping in transmission lines has attracted more and more attention and attention, because once a large area of ​​galloping occurs, it will cause flashover and tripping of the line in the slightest, and deformation of fittings and damage to insulators in severe cases Serious accidents such as disconnection of wires, collapse of towers, etc., resulting in large-scale power outages and affecting the safe and stable operation of the power grid

Abstract

The invention provides an annular anti-galloping device, and the anti-galloping device comprises a regularly polygonal frame, wherein each intersection is provided with a connection wire clamp. The connection wire clamps and the regularly polygonal frame are located on the same plane, and the connection wire clamps are arranged along the symmetric axis of the regularly polygonal frame. The improvement lies in that the interior of the regularly polygonal frame is provided with regularly polygonal energy-consuming mechanisms, wherein the number of the regularly polygonal energy-consuming mechanisms is the same as the number of sides, and the intersections of all sides of the regularly polygonal energy-consuming mechanisms are correspondingly connected with the connection wire clamps. Compared with the prior art, the anti-oscillation device can effectively reduce the possibility of conductor galloping of a power transmission line based on the energy consumption principle, and improves the safety and reliability of the power transmission line.

Description

technical field [0001] The invention relates to a dance preventer for power transmission lines, in particular to a ring-shaped dance preventer for power transmission lines based on the principle of energy consumption. Background technique [0002] Power transmission is achieved by using a transformer to boost the power generated by the generator, and then connecting it to the transmission line through circuit breakers and other control equipment. According to the structural form, transmission lines are divided into overhead transmission lines and cable lines. The overhead transmission line erected on the ground is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc. [0003] In recent years, with the accelerating pace of power development, the power grid has also developed rapidly, the operating voltage level of the power grid system has continued to increase, and the network scale has also continued to expand. Th...
