Background technology
The lead that transmits electric power is under certain meteorological condition, wind energy can be fastened in the vibration of lead and iron tower formation by continuous action, lead can be waved, waving of lead is a kind of energy, and this energy is passed to iron tower by the junction point of lead and iron tower, and iron tower and lead constitute vibration system, the continuous action that vibration ties up to wind energy forms resonance and forced vibration down, formed waving of transmission line, and waved the prolongation of understanding along with the time, the amplitude of waving is increasing.This energy of waving destroys the iron tower structure on the one hand, can form short circuit dischange between alternate or iron tower because of waving on the other hand, and waving of lead is one of key factor of influence transmission of electricity safety.
Lead kinetic energy is the junction nodes of lead and iron tower to the node of iron tower transmission, and this node has the characteristics of the flexibility of lead to the sudden turn of events of iron tower relative stiffness.On this node, in the transmittance process of energy, lead forms huge impact to iron tower, this impact failure the integrality of iron tower structure, as bolt looseness, bolt hole cracking, the distortion of tower material, structural failure etc.
In order to prevent conductor galloping, taked a series of measure on the current power transmission circuit, as add measures such as inter-phase spacer, stockbridge damper, certain anti-dance effect has been played in these measures, but very big shortcoming is also arranged, as inter-phase spacer fracture, new circle wave, stockbridge damper gets loose, stockbridge damper is shifted and the anti-dance effect is undesirable etc.
The utility model content
The technical problems to be solved in the utility model provides a kind of device that can prevent that conductor galloping, protection iron tower are not destroyed.
Addressing the above problem the technical scheme of being taked is: sleeve, the pressing plate that is arranged on sleeve one end that stops the device of transmission pressure vibration to comprise to fixedly connected with hanger I, be arranged on creeping-increasing skirt around the sleeve, be arranged on sleeve lining coil, be sleeved on pull bar of fixedlying connected in the sleeve and the permanent magnet of fixedlying connected with pull bar with hanger II.
Be provided with damping fluid in the cavity that sleeve and pressing plate constitute, the drag link sleeve that is arranged in the sleeve is equipped with spring.
Permanent magnet is arranged by permanent magnet and is formed, and the S of permanent magnet is consistent on the circumferential direction of same horizontal plane with the N utmost point, is the staggered setting of arranging at the S and the N utmost point along permanent magnet on the vertical direction of pull bar.
Good effect of the present utility model is: by hanger I sleeve is connected on the transmission pressure, by hanger II pull bar is connected on another transmission pressure, sleeve lining is provided with coil, permanent magnet is arranged by many permanent magnets and is formed, the S of permanent magnet is consistent on the circumferential direction of same horizontal plane with the N utmost point, be staggered at the S and the N utmost point along permanent magnet on the vertical direction of pull bar, can make permanent magnet like this when moving together along with the transmission pressure that is connected with pull bar, can make the change frequency maximum of magnetic flux in the coil, can produce eddy current to greatest extent, produce eddy-current heating, utilize that kinetic energy makes coil produce eddy current in the transmission pressure motion, thereby consumed the kinetic energy of lead, thereby avoided the accumulation of lead kinetic energy to produce big destruction.
The effect of creeping-increasing skirt is to increase creep distance, prevents creeping discharge; Can fill damping fluid in the cavity, the effect of damping fluid is to increase resistance and heat radiation, can prevent like this that coil is overheated to be burnt out; Can also be set with spring on pull bar, spring can be stored the energy that lead passes to pull bar, further reduces the amplitude of waving of lead, prevents that it from producing destruction to iron tower.
