Problems solved by technology

[0005] The widely used power equipment multi-split spacers on transmission lines have poor stability, poor strength, and weak ability to prevent transmission line galloping, which are far from meeting the needs of UHV long-distance and large-span transmission development in the power industry.
In order to solve these problems, it is necessary to maintain a high distance to the ground when designing the line, install a control galloping device, and require a large amount of line maintenance every year, which will cost a lot of money

Embodiment Construction

[0029] Invention example 1: such as figure 2 As shown, in the example of the present invention, a multi-split wire spoiler dancer includes a frame 3 and six clamps 1 arranged outwardly and perpendicularly to its axial direction; An inner frame 4 is arranged on the same plane inside the rectangular frame 3, and fixed columns 7 are vertically arranged on the regular hexagonal frame 3, and spoiler wires 6 are wound on the fourteen fixed columns 7.

[0030] The inner frame 4 is a circle on which hollow grooves 2 and fixing holes 8 are arranged, and the frame 3 is a regular hexagon.

[0031] The fixed column 7 is a cylinder with a length of 460 mm and a diameter of 35 mm, and the spoiler line 6 is a cylindrical section line with a diameter of 12 mm.

[0032] The end faces of the fixing columns 7 are connected with the inner frame 4 .

[0033] Both ends of the four bracket connectors 5 are respectively provided with fixing holes for connecting the inner and outer frames.

Abstract

The invention relates to a current-disturbing anti-galloping device for multi-split conductors. The anti-galloping device comprises a frame and wire clamps disposed on the frame, and the wire clamps are perpendicular to the axial direction of the frame and are disposed outward. The anti-galloping device is characterized in that an inner frame is disposed in the same plane as the frame, the frame is axially provided with fixing columns, and current disturbing wires are wound on the fixing columns. The anti-galloping device is suitable for preventing multi-split transmission lines from galloping. By designing and improving a common multi-split spacer, the characteristics of the flow field between multi-split conductors are effectively changed, wire galloping energy is absorbed, the galloping rate of transmission lines is reduced, and the safety and reliability of lines are improved.

Description

technical field [0001] The invention relates to a metal fitting for electrical equipment, in particular to a multi-split wire turbulence preventer. Background technique [0002] With the continuous high-speed growth of electricity demand and the acceleration of electric power development, the electric power industry has developed rapidly. Optimizing the allocation of energy resources, ensuring national energy security, and providing high-quality and reliable power supply for national economic and social development are important missions of the power industry in serving the construction of a socialist harmonious society. [0003] The galloping of multi-split transmission lines on EHV lines has the characteristics of low frequency, large amplitude, and one or n half-wave forms within the span. On a typical EHV line, the galloping frequency is 0.15 Hz to 1 Hz, and the galloping amplitude is 0.1 to 1 times the sag of the conductor within the span. [0004] The degree of harm ...
