Background technology
The vibration of overhead power transmission line line conductor and lightning conducter and aerial fiber cable circuit is by wind-induced periodic wobble on vertical plane, and forms the little standing wave of a series of amplitudes in whole span.Lead vibration for a long time can make conductor material produce additional mechanical stress, As time goes on causes lead to produce tired and ruptures.The vibration of lead is very big to the safe operation threat of circuit, except that causing wire fracture, also may make electric insulator steel foot loose or dislocation, the wearing and tearing of gold utensil accessory, even the destruction of causing shaft tower.The effective ways of eliminating conductor vibration are to install stockbridge damper on lead additional.When lead was vibrative, the relative motion of stockbridge damper had absorbed the vibrational energy of lead, thereby reduced and eliminated the vibration of lead.Various stockbridge dampers are different according to structure, weight and physical dimension, all have certain natural frequency and vibrationproof performance.Yet the fixed form of the stockbridge damper that generally uses now employing adopts bolt type to fix usually, is easy to lead is caused damage in the process of installing.Simultaneously because overhead transmission line after operation a period of time, lead can produce creep (variation in diameter), thereby causes the stockbridge damper slippage or come off, and brings huge harm for the safe and stable operation of circuit.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of aesthetic in appearancely, and it is convenient to install, and weather resistance is good, and has the multifrequency point pre reeled silk type stockbridge damper of superior vibration-isolating effect.The utility model can be good at solving traditional stockbridge damper and holds tight lead, wearing and tearing lead, problem such as come off easily.
Technical characterictic of the present utility model be designed a kind of can be firm, convenient, and the chuck that can install rapidly is connected with lead, this chuck adopts preformed armor rods to be fixed on the node location of lead appointment.On chuck, adopt the mode of crimping to fix two galvanized strand wiress, the other end crimping of twisted wire " stoke cloth Ritchie " (tuning fork) structure tup.Chuck adopts the manufacturing of fine aluminum alloy, adopts the process forming that stretches, and has characteristics in light weight, that intensity is high, weather resistance is good; The chuck unique design can directly adopt preformed armor rods to be fixed on the lead of assigned address, can avoid crushing and the lead that weares and teares, and can avoid the slippage of stockbridge damper again.Simultaneously stockbridge damper to the shearing force of lead from the width extending of chuck on the length of whole section preformed armor rods, significantly reduced damage to lead.Preformed armor rods adopts the structure of aluminium Baogang, and its internal diameter is slightly less than lead, can effectively avoid under lead creep (diameter diminishes) situation chuck loosening.All adopt the technologies of crimping between tup and the steel strand wire and between steel strand wire and the chuck, avoided corrosion and looseningly caused coming off of tup.The part that this pre reeled silk type stockbridge damper contacts with lead all adopts the material of aluminium alloy and aluminium Baogang, and the generation of the magnetic hysteresis eddy current of avoiding can reach desirable energy-saving effect.
Below introduce structure of the present utility model in detail: a kind of pre reeled silk type stockbridge damper of ultra-high-tension power transmission line.It is characterized in that the chuck that aluminium alloy is made, can fixedly secure preformed armor rods on lead to chuck, two galvanized strand wiress of the lower end crimping of chuck, the other end of steel strand wire are fixed two tuning-fork type tups that vary in weight respectively.The chuck unique design make it adopt preformed armor rods to be fixed on the lead very easily, and it is fastening not need to adopt bolt to carry out, and does not need to adopt simultaneously any instrument when mounted.
When the utility model uses, chuck is suspended on the lead appointed positions, gets final product with evenly natural being wrapped on the lead of preformed armor rods of hand with both sides.
The utility model has the advantages that: the shortcoming of having eliminated the bolt fastening stockbridge damper.When installing, do not need to use any instrument, free-hand can finishing.Quick and easy for installation, construction cost is cheap.
Description of drawings
