Abstract

The invention discloses a self-adaptive electromagnetic energy dissipation anti-galloping vibration damping device which comprises an outer box body, wherein an iron core is arranged in the outer boxbody, the top of the iron core is connected with a mounting piece fixed on the inner wall of the outer box body through a first elastic device, the bottom of the iron core is connected with a piston through a second elastic device, and the piston can move up and down relative to the outer box body; a permanent magnetic pole is arranged in the mounting piece, a permanent magnetic pole is installedin the piston, and the polarities of the two permanent magnetic poles are opposite; a magnet exciting coil is arranged in a gap formed by the iron core and the outer box body, and is connected with acontroller mounted in the box body and a power supply mounted in the outer box body in series to form a closed loop; an upper clamping device connected with the outer box body is arranged above the outer box body, and a lower clamping device connected with the piston is arranged below the outer box body; a displacement monitor is installed on the inner wall of the outer box body and used for monitoring displacement of the first elastic device and the second elastic device; and the displacement monitor is connected with a pre-controller.

Description

technical field [0001] The invention relates to the field of vibration reduction of power system transmission lines, in particular to an adaptive electromagnetic energy consumption anti-galling vibration reduction device. Background technique [0002] With the rapid development of social economy and industry, the country's demand for electric energy is growing rapidly. As an important carrier of electric energy transportation, transmission lines are of great significance to ensure their safety and stability. Galloping of transmission lines has been an important factor affecting the safety of transmission lines in various regions for a long time. The transmission lines in transmission lines are affected by environmental meteorological conditions such as wind, low temperature, ice and snow all the year round, and there will be breeze vibration, sub-gap vibration, along-line vibration and Dancing fatigue vibrations in these four directions. Not only will it lead to flashover a...
