Abstract

The invention provides a high-energy-consumption wave-prevention device. The high-energy-consumption wave-prevention device comprises a cover and a base. The high-energy-consumption wave-prevention device is characterized in that a joint plate and a spring are sequentially arranged in the direction from the cover to the axis of the base and the cover is a cover body which is made of rubber-based high-energy-consumption materials and is embedded into the lateral wall of the base. Compared with the prior art, the high-energy-consumption wave-prevention device is good in wave prevention performance, capable of effectively preventing electric transmission lines from waving under ice and wind shock excitation, simple in structure, easy to install, capable of being matched with a wire spacer bar, good in economic performance and suitable for large-scale popularization and use.

Description

technical field [0001] The invention relates to an anti-dance device, in particular to a high-energy consumption anti-dance device for power transmission lines. Background technique [0002] In recent years, with the continuous acceleration of China's electric power development, China's 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. At present, power grid construction has become the main direction of my country's power construction, and the prospect of power grid construction is attractive. . During the "Twelfth Five-Year Plan" period, my country's power grid investment scale continued to expand. By 2020, a unified strong smart grid will be fully built, and the goal of building a world-class power grid will be initially realized. [0003] As an important part of the power system, the transmission line is responsible for the transmission of electric ener...
