Product Description

Raws li ib feem tseem ceeb ntawm cov hluav taws xob fais fab fittings, kev siv cov pas nrig spacer yog nquag siv nyob rau hauv kev sib kis kab ntawm Tuam Tshoj lub hwj chim daim phiaj, thiab nws cov kev thov ntau lawm kuj nce.Txhawm rau tiv thaiv kev nplawm ntawm cov xov hlau thiab txo qhov kev vibration ntawm cov xov hlau los ntawm cov cua, lub luag hauj lwm ntawm lub spacer ntawm cov xov hlau yog ib qho tseem ceeb heev, zoo ib yam li cov nyhuv ntawm anti-vibration rauj, tab sis lub luag hauj lwm tseem ceeb ntawm lub spacer yog los txo cov kev vibration ntawm cov spans.
Lub pas nrig spacer hais txog cov fittings ntsia rau ntawm cov xov hlau sib cais los kho qhov kev ncua deb ntawm cov xov hlau sib cais, txhawm rau tiv thaiv cov xov hlau los ntawm kev nplawm ib leeg, txwv tsis pub cov cua vibration thiab sub-gap vibration.Lub spacer feem ntau ntsia nruab nrab ntawm qhov ncua sij hawm, thiab ib qho yog ntsia ntawm ib ntus ntawm 50-60m.Ob-split, plaub-split, rau-split, thiab yim-split hlau spacer rods, piv nrog rau kev vibration amplitude ntawm cov split hlau tom qab txhim kho tus pas nrig spacer thiab tsis muaj tus pas nrig, ob-split hlau yog txo los ntawm 50%. , thiab plaub-split hlau yog txo los ntawm 87% thiab 90%.
Lub ntsiab yuav tsum tau rau lub spacer yog hais tias lub clamp yuav tsum muaj txaus tuav thiab yuav tsum tsis txhob loosen thaum lub sij hawm lub sij hawm ua hauj lwm mus sij hawm ntev, thiab tag nrho lub zog yuav tsum muaj peev xwm tiv taus lub centripetal quab yuam ntawm txhua txoj kab sib cais thaum txoj kab luv luv thiab qaug zog hauv qab. kev vibration mus ntev.Lub spacer yuav muab faib ua ob pawg: damping thiab rigidity nyob rau hauv cov nqe lus ntawm kev ua tau zoo.Lub damping spacer yog embedded nrog ib tug hnav-resistant roj hmab ncoo nyob rau hauv nws tsiv qhov chaw, thiab siv lub damping ntawm cov roj hmab ncoo kom haus lub zog vibration ntawm tus neeg xyuas pib, yog li ua ib tug damping nyhuv ntawm kev co ntawm tus neeg xyuas pib..Rigid spacers tsis muaj xws li cov roj hmab pads feem ntau yog siv nyob rau hauv cov cheeb tsam uas kev co tsis yooj yim rau tshwm sim los yog rau jumper spacers vim tsis zoo vibration absorption kev ua tau zoo.
Lub damping spacer yog ib qho yooj yim los yog semi-rigid spacer uas tuaj yeem txo qhov kev vibration los yog qhov sib txawv ntawm qhov sib cais ntawm tus neeg xyuas pib.kuv lub teb chaws 500kV kis tau tus mob siv ib tug plaub-split conductor qauv.Lub spacer yog lub ntsiab haum nyob rau hauv lub split hlau qauv.Cov haujlwm yooj yim ntawm tus kab txuas yog: Txhawm rau tiv thaiv kom tiv thaiv cov xov hlau ntawm cov xov hlau, txhawm rau txhawm rau txhawb qhov kev co ntawm txoj kev tshau thiab kev co ntawm cov sub-sib txawv.Feem ntau siv yog damping spacer, uas muaj kev vibration absorption kev ua tau zoo dua li qhov tsis sib xws.Yog li ntawd, kev ntsuam xyuas kom muaj nuj nqis ntawm damping spacer qhov kev co-absorbing tau dhau los ua tus yuam sij rau kev tshawb fawb, tsim, tsim thiab xaiv cov damping spacer.

Technical parameters

Khoom nta thiab kom zoo dua

1. Damping spacer thiab non-damping spacer.Cov yam ntxwv ntawm damping hom spacer yog cov roj hmab siv los ua cov khoom damping ntawm qhov sib koom ua ke ntawm lub spacer kom haus lub zog vibration ntawm cov hlau thiab tsim cov nyhuv damping ntawm kev co ntawm cov hlau.Yog li ntawd, hom spacer no haum rau txhua cheeb tsam.Txawm li cas los xij, xav txog kev lag luam ntawm cov kab xa hluav taws xob, hom spacer no feem ntau yog siv rau cov kab hauv thaj chaw uas cov neeg siv hluav taws xob muaj kev co.Cov tsis-damping spacer muaj kev poob siab tsis zoo thiab tuaj yeem siv rau cov kab hauv thaj chaw uas kev co tsis yooj yim tshwm sim lossis siv los ua jumper spacer.
2. Ob, plaub lossis ntau qhov sib cais conductors yog siv rau txhua theem tus neeg xyuas pib ntawm qhov ntev thiab muaj peev xwm loj EHV kis tau tus mob.Tam sim no, 220KV thiab 330KV kis tau tus mob kab siv ob-split conductors, 500KV kis tau tus mob kab siv peb-split thiab plaub-split conductors, thiab ultra-high voltage kis kab nrog voltages siab tshaj 500KV siv rau-split thiab ntau split conductors.Txhawm rau kom ntseeg tau tias qhov kev ncua deb ntawm cov hlua hlau sib cais tseem tsis hloov pauv kom tau raws li kev ua haujlwm ntawm hluav taws xob, txo qhov muaj peev xwm gradient, thiab nyob rau hauv cov ntaub ntawv ntawm ib tug luv luv Circuit Court, lub electromagnetic quab yuam yuav tsis raug generated ntawm cov hlau harnesses, ua rau kev sib nrig sib attraction. thiab kev sib tsoo, lossis txawm tias qhov kev sib tsoo tam sim no tshwm sim, tab sis tom qab qhov kev sib tsoo raug tshem tawm sai sai tuaj yeem rov qab mus rau lub xeev qub, yog li spacer rods tau teeb tsa ntawm qee qhov kev ncua deb.Lub installation ntawm spacer rods kuj tuaj yeem ua lub luag haujlwm qee yam hauv kev txwv qhov kev vibration ntawm qhov nruab nrab ncua sij hawm thiab kev co ntawm cov cua.

Cov khoom lag luam

Lub hauv paus ntsiab lus ua haujlwm ntawm damping spacer:
qhov kev vibration ntawm cov hlau uas tshwm sim los ntawm cua thiab kev vibration ntawm lub sub-gap induced los ntawm cov cua muaj zog yuav ua rau qaug zog ntawm cov hlau, thiab lub looseness ntawm fastener yuav ua rau cov hlau hnav.Split wires siv spacers kom ruaj khov electromechanical kev ua tau zoo.Lub damping spacer yog siv cov elasticity ntawm cov khoom siv roj hmab kom tau raws li qhov xav tau rigidity kom nws muaj peev xwm muaj peev xwm txaus thaum tswj xyuas qhov ntev geometric ntawm cov hlau sib cais.Siv cov viscosity ntawm cov roj hmab kom nqus tau lub zog txaus nyob rau hauv alternating kev ntxhov siab kom ua tiav lub hom phiaj ntawm suppressing cua vibration.
Lub damping kev ua tau zoo ntawm lub damping spacer muaj feem xyuam rau damping coefficient ntawm cov khoom siv roj hmab.Txawm li cas los xij, cov nyhuv damping ntawm cov khoom siv roj hmab muaj feem cuam tshuam nrog cov qauv thiab siv cov xwm txheej ntawm lub spacer.Kev ua haujlwm damping yog qhov tseem ceeb rau kev tshawb nrhiav thiab tsim cov damping spacers.Cov yam ntxwv ntawm kev vibration absorption thiab durability ntawm ntau hom damping spacers tuaj yeem kwv yees thiab sib piv los ntawm kev sim lawv qhov nruj thiab kev siv zog.
Txoj cai xeem
ntawm lub damping spacer: Ib qho kev txhawb nqa xaim ntawm lub damping spacer txuas nrog lub slider ntawm lub simulated vibration rooj los tsim lub rocker slider mechanism, thiab kev co ntawm slider yog siv los simulate lub xeev ua hauj lwm ntawm lub damping spacer ntawm lub overhead. hlau.Ntsuas lub voj kab ntawm damping spacer pas nrig ntawm cov nyiaj siv ua haujlwm los txhawb lub amplitude ntawm txoj kab kev txhawb nqa hloov nrog lub zog sab nraud.Cov cheeb tsam uas nyob ze ntawm kab kab no yog lub zog poob txhua lub lim tiam.Qhov nruab nrab nruj yog xam los ntawm qhov siab tshaj plaws sab nraud quab yuam thiab amplitude.
Anti-dancing mechanism ntawm lub clamp teb spacer:
cov dej khov txheej ntawm ib qho xaim thiab sib cais cov hlau sib txawv heev.Lub axis ntawm cov kab sib kis feem ntau yog eccentrically iced thiab tig mus rau sab cua.Tom qab tus neeg xyuas pib yog coated nrog dej khov, qhov loj tsis txaus yuav twist nyob ib ncig ntawm nws tus kheej axis.Tus ntoo khaub lig-sectional duab ntawm cov iced conductor ua ib yam thaum lub sij hawm tus txheej txheem ntawm nruam twisting thiab ice txheej.Nws muaj cov nyhuv ntawm suppressing lub galloping ntawm cov hlau.Cov kab hluav taws xob sib cais muaj qhov sib txawv ntawm qhov sib txawv los txhim kho cov khoom siv hluav taws xob, kom cov khoom siv hluav taws xob tsis tuaj yeem tig raws li nyob ze ntawm cov pas nrig spacer.Nyob rau tib lub sijhawm, vim qhov kev sib txuas ruaj khov, qhov torsional rigidity ntawm luv luv sub-gauge conductor yog nce.Lub sub-conductor ntawm qhov sib txawv yuav tsum muaj lub zog zoo li qub uas yuav tsum tau thim rov qab, thiab nws nyuaj rau tus neeg xyuas pib tig ncig nws tus kheej axis.Lub torsion coefficient ntawm cov hlau sib cais yog loj dua li ntawm ib lub xaim, thiab cov icing tsis sib xws yog qhov hnyav dua, yog li cov xaim sib cais yog feem ntau yuav gallop dua li ib lub xaim.
Lub hauv paus ntsiab lus tiv thaiv kev seev cev ntawm cov hlau clamp teb spacer: lub rotatable hlau clamp yog tus yuam sij rau tiv thaiv kev seev cev.Thaum cov sub-conductors raug kho nrog spacers, ib nrab ntawm cov sub-conductors tuaj yeem tig nyob rau hauv ib qho chaw.Txawm nyob rau hauv cov ntaub ntawv ntawm icing, cov neeg xyuas pib kuj siv tau cov dej khov-coated thiab snow-them eccentric loj rau twist, thiab tsim los ntawm twisting nyob ib ncig ntawm lawv tus kheej axes evenly round nrog icing.Yog li kom ua tiav lub hom phiaj ntawm suppressing cov dej khov-coated galloping ntawm cov hlau.
