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

Abstract

The invention relates to a damping connection type multi-split conductor current-disturbing anti-galloping device. The device comprises a framework and wire clamps, wherein the wire clamps are arranged on the framework, perpendicular to the axial direction of the framework, and arranged outwardly; an inner framework and damping apparatuses are arranged on the same plane of the framework; fixed columns are axially fixed on the framework; and current-disturbing wires wind the side faces of the fixed columns. The current-disturbing anti-galloping device is applicable to prevention of multi-split power transmission line galloping; common multi-split spacing rods are designed and improved, so that the flow field characteristics among the multi-split conductors are effectively changed, the conductor galloping energy can be absorbed, the galloping probability of the power transmission line is lowered, and security and reliability of the line are improved.

Description

technical field [0001] The invention relates to a metal fitting for electrical equipment, in particular to a damping connection type multi-split wire turbulence dance 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....
