Yuav tiv thaiv Aeolian kev co hauv OPGW Cables: Lub luag haujlwm ntawm kev co Dampers
Hauv kev sib txuas hluav taws xob siv hluav taws xob, Optical Ground Wire (OPGW) cables ua lub luag haujlwm dual: lawv ua cov ntaub thaiv npog los tiv thaiv cov kab los ntawm xob laim thiab ua haujlwm siab - kev sib txuas lus nrawm. Txawm li cas los xij, vim hais tias OPGW cables tau teeb tsa rau saum toj kawg nkaus ntawm cov xaim hluav taws xob, lawv tau raug cuam tshuam los ntawm ib puag ncig. Ntawm cov no,cable aeolian kev coyog qhov uas ntsiag to tshaj plaws tab sis kev hem thawj.
Rau cov neeg siv khoom vaj khoom tsev tswj hwm thiab cov neeg ua haujlwm yuav khoom nrhiav kev ntseeg siabkis kab mob kho vajtse, kev nkag siab yuav ua li cas txo qhov kev ntxhov siab no yog qhov tseem ceeb. Daim ntawv qhia kev qhia no tshawb xyuas qhov cua vibration ua rau qaug zog puas tsuaj thiab yuav ua li cas txhim kho txoj caiOPGW kev co damperncua koj daim phiaj infrastructure lub neej.
Lo lus teb ncaj qha: Aeolian Vibration yog dab tsi thiab Yuav Ua Li Cas Ua Rau OPGW?
Aeolian kev vibrationyog qhov siab - zaus, qis- amplitude oscillation induced los ntawm du, qis- cua nrawm (feem ntau yog 1 txog 7 m / s) tshuab perpendicular mus rau cov kab sib kis. Thaum cov cua hla dhau OPGW cable, nws tsim alternating vortices nyob rau sab saum toj thiab hauv qab ntawm kab (lub npe hu ua Von Kármán vortices).
Qhov tshwm sim no ua rau muaj kev ntxhov siab ntawm txoj kab ntsug ntsug, feem ntau yog tsom rau ntawm cov ntsiab lus nruj ncua kev kawm, xws li qhov twg cov kab sib ntsib.ADSS / OPGW ncua kev kawm ntawv clamp. Nyob rau tib lub sijhawm, cov kev vibrations tsis tu ncua ua rau:
Fretting Fatigue: Txhua tus neeg txhuas-clad steel hlau nyob rau hauv OPGW txheej txheej pib hnav, tawg, thiab snap.
Fiber ntau attenuation: Internal stainless hlau xoob raj warp, inducing micro- khoov uas tawg lub laser teeb liab thiab ua rau cov ntaub ntawv poob.
Kho vajtse Loosing: Kev co tsis tu ncua tuaj yeem loosen bolts thiab pins nyob ib saboverhead power line accessories, txaus ntshai kab hauv zos poob.
Kev daws: Mechanism ntawm Stockbridge Vibration Dampers
Txhawm rau tiv thaiv cov quab yuam cyclic, lub zog siv hluav taws xob thoob ntiaj teb cia siab rauStockbridge kev co damper.
Nws ua haujlwm li cas
Ib yamOPGW kev co dampermuaj ib tug ruaj ntseg clamp, ib tug saj zawg zog steel tub txib cable, thiab ob uniquely zoo li tus luj ntawm ob tog. Thaum cua excites lub OPGW cable, lub damper luj oscillate tawm ntawm theem nrog cov kab. Cov tub txib hloov tau yooj yim khoov rov qab thiab tawm mus, nqus lub zog kinetic ntawm kev co thiab hloov mus rau hauv lub zog thermal tsis zoo. Cov txheej txheem no zoo clamps rau tag nrho amplitude ntawm yoj, tiv thaiv cov qauv cable.
Muab xam qhov chaw thiab kom muaj nuj nqis
Txhawm rau kom ntseeg tau tias qhov kev ua tau zoo tshaj plaws, cov chaw tsim khoom siv kho vajtse siv tshwj xeeb cua damping software los xam qhov tseeb qhov chaw ntawm cov khoom siv. Cov ntsiab lus suav hauv:
Kab Tension & Span Length: Ntev ntev (piv txwv li, hla dej los yog hav) muaj kev tsim hluav taws xob ntau dua thiab xav tau ntau yam dampers.
Anti-Node Distance: Dampers yuav tsum tau muab tso rau ze ntawm qhov tiv thaiv -nodes (cov ntsiab lus ntawm qhov siab tshaj plaws yoj hloov chaw) es tsis yog cov nodes (cov ntsiab lus ntawm xoom txav). Feem ntau, lawv raug kho ntawm qhov kev ncua deb (\\(X\\)) los ntawm qhov nruab nrab ntawm kev ncua lossis nro clamp sib dhos.
