Problems solved by technology

[0006] However, due to the extremely complex mechanism of breeze vibration, the results of theoretical calculation or experimental research are often very different from the actual situation in the field.
The currently designed anti-vibration scheme cannot effectively solve the problem of breeze vibration. In recent years, lines equipped with anti-vibration devices still suffer damage from breeze vibration

Abstract

The invention discloses an active antivibrator and active vibration-proof method of an overhead transmission line. The active antivibrator comprises a shell, a power source, a control circuit, an electric motor, a transmission mechanism and a vibration-proof actuating mechanism, wherein the shell is provided with a fixing element which is used to fix the antivibrator on a line, the control circuit, electric motor and transmission mechanism are arranged in the shell and the power source provides electrical energy; the control circuit controls the movement of the electric motor, the electric motor drives the vibration-proof actuating mechanism to move and change the centre-of-gravity position through the transmission mechanism so as to counteract the vibration of the lead by means of reaction and realize the aim of inhibiting the breeze vibration of the lead.

Description

technical field [0001] The invention relates to an overhead transmission line, in particular to an active anti-vibration device and an active anti-vibration method for an overhead transmission line. Background technique [0002] The breeze vibration of the wire is a high-frequency, small-amplitude wire movement caused by the breeze, which is the main cause of accidents such as wire fatigue and broken strands. Since the United States first discovered the vibration and broken strands of the conductor at the strait crossing of a transmission line at the beginning of the last century, people have been conducting research on the problem of breeze vibration, including vibration mechanism, anti-vibration theory, vibration test, anti-vibration device, anti-vibration Vibrating wire and many other aspects. Over the past decades, rich experience has been accumulated, and various specific anti-vibration technical measures have been designed and applied on overhead transmission lines. ...
