Problems solved by technology

At present, although the common anti-vibration hammers on the market can play a certain role in eliminating the natural vibration of the line and the resonance caused by the wind during use, because the hammer itself swings with the wires, its own resistance is small. , when being swayed by wires, the best shockproof effect cannot be achieved
When relying on factors such as increasing the volume or force-bearing area to increase resistance, it will also bring other problems such as heavy load, which will directly or indirectly cause damage to the line, and the effect of shockproof protection cannot be achieved or the shock absorption effect is poor.

Abstract

The invention discloses an intelligent stockbridge damper, and relates to the technical field of manufacturing of a power metal fitting. The intelligent stockbridge damper comprises an A hanger, a B hanger, a C hanger and a holding ring successively form the left to the right. An A stepping motor is installed above the B hanger; an arc-shaped tooth bar engaged with the gear of the A stepping motor is fixed on the upper surface of the C hanger; a swing ball is connected below the C hanger; an installation substrate is connected below the B hanger; one side of the installation substrate is provided with a B stepping motor; a vertical tooth bar engaged with the gear of the B stepping motor is elastically connected below the A hanger; the other side of the installation substrate is provided with a processor for controlling the A stepping motor and the B stepping motor; the holding ring is provided with a fastening bolt and a triaxial acceleration transducer; and the output end of the triaxial acceleration transducer is connected with the input end of the processor. The intelligent stockbridge damper has the following advantages: information is collected by the triaxial acceleration transducer and is determined and processed by the processor, the motors are controlled to perform active inverse motion, and thus a shockprooft protection effect is exhibited.

Description

technical field [0001] The invention relates to the technical field of electric fittings. Background technique [0002] The overhead power lines are affected by meteorological conditions such as wind, ice, and low temperature, causing the lines to vibrate and dance. The vibration frequency is high and the amplitude is small. The wind vibration causes the overhead line to be repeatedly bent at the suspension point, causing material fatigue, and finally leads to broken strands and broken lines. The frequency of galloping is very low, but the amplitude is very large, which can easily cause phase-to-phase flashover, resulting in serious accidents such as line tripping, power failure or burning of wires. A shock hammer is just a length of iron rod. Because it is hung at the suspension point of the line tower pole, it can absorb or weaken the vibration energy on the line, change the swing frequency of the line, and prevent the line from vibrating or galloping. At present, altho...
