Embodiment Construction

[0027] The specific implementation manner of the present invention will be further described in detail below in conjunction with the drawings and specific examples.

[0028] Such as figure 1 , figure 2 As shown, the present invention proposes a semi-active anti-vibration device for overhead transmission lines, wherein the anti-vibration device includes a housing, a power supply, a control circuit, a motor, a transmission mechanism, and an actuator, wherein the housing is provided with the anti-vibration The vibrator is fixed on the fixing piece on the wire, so that the position of the vibration isolator is fixed relative to the wire (not shown in the figure). The control circuit, motor, and transmission mechanism are set in the casing, and the power supply provides electric energy. The control circuit controls the action of the motor. The actuator has an adjustable arm. The motor drives the adjustable arm of the actuator through the transmission mechanism to change the execu...

Abstract

The invention discloses a semi-active vibration isolator of an overhead power transmission line and a semi-active vibration isolation method. The semi-active vibration isolator of the overhead power transmission line comprises a shell, a power supply, a control circuit, a motor, a transmission mechanism and an actuating mechanism, wherein the shell is provided with a fixture for fixing the vibration isolator to the wire; the control circuit, the motor and the transmission mechanism are arranged in the shell and powered by the power supply; the actuating mechanism is provided with an adjustable arm; the action of the motor is controlled by the control circuit; the adjustable arm of the actuating mechanism is driven to act by the motor through the transmission mechanism; and the damping characteristic of the actuating mechanism is varied through the mechanical action for varying the arm length of a damper so as to achieve the purpose of suppressing the aeolian vibration of the wire.

Description

technical field [0001] The invention relates to an anti-vibration technology for an overhead power transmission line, in particular to a semi-active anti-vibration device and a semi-active anti-vibration method for an overhead power 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 d...
