Thaum peb tham txog kev txhawb nqa nws tus kheej hauv huab cua, ib qho ntawm cov kev siv ntau tshaj plaws rau kev sib kis mus ntev yog kev tso cov fiber ntau optic cables hauv high-voltage towers.
Tam sim no cov qauv high-voltage tshaj tawm hom kev teeb tsa zoo nkauj heev vim tias lawv txo cov peev txheej hauv cov txheej txheem tsim nyog los tsim cov kev sib txuas fiber ntau optic tshiab, cov no, twb tau tsim.Tab sis cov kab hauv high-voltage towers feem ntau nthuav tawm cov kev cov nyom loj, feem ntau pom nyob rau hauv cov khoom siv uas tswj cov hluav taws xob hluav taws xob siab: kev taug qab cov nyhuv thiab corona tawm.
Txoj kev taug qab yog dab tsi?
Kuj paub nyob rau hauv kev lag luam raws li qhuav banding los yog hluav taws xob arborescence, cov kev taug qab cov nyhuv yog hais txog lub dielectric puas ntawm insulating cov ntaub ntawv, ib tug irreversible txheej txheem muab los ntawm ib feem ntawm hluav taws xob tawm uas nkag mus rau hauv los yog nyob rau saum npoo ntawm ib tug dielectric cov ntaub ntawv thaum nws raug mus rau lub sij hawm ntev. -voltage hluav taws xob kev nyuaj siab.
Corona tawm
Lwm qhov kev pheej hmoo uas cov kab hluav taws xob txhawb nqa nws tus kheej khiav thaum lawv tau teeb tsa hauv cov tsev hluav taws xob siab yog cov nyhuv corona, tseem hu ua corona tawm, txhais tau tias yog ionization ntawm cov roj uas nyob ib puag ncig tus neeg xyuas pib.Rau kev txhim kho fiber ntau optic cable, cov pa roj yog cua nws tus kheej, uas nyob ib puag ncig cov kab sib kis.
Cov nyhuv corona muaj nyob rau hauv txhua yam khoom siv thiab kev teeb tsa uas ua haujlwm nrog lossis ua hluav taws xob.Nyob rau hauv peb lub neej niaj hnub, qhov no feem ntau tsis pom thiab tsis cuam tshuam rau peb vim qhov voltages thiab hluav taws xob muaj peev xwm uas peb ib txwm siv.Txawm li cas los xij, nyob rau hauv high-voltage towers, cov voltages uas khiav ntawm lawv cov kab yog siab heev (los ntawm 66 kV mus rau 115 kV), ua rau cov corona cov nyhuv uas tsim los ntawm cov conductors mus rau qhov dav dav.
Thaum raug rau sab nraum zoov, cables raug cuam tshuam los ntawm ob yam tseem ceeb: qhov txheeb ze av noo ntawm huab cua thiab cov pa phem ntawm ib puag ncig.Nrog rau cov av noo ntau, dej ntau condenses ntawm qhov chaw ntawm lub cable;thiab qhov ntau dua qhov ua paug ntawm ib puag ncig, ntau qhov khoom (plua plav, hnyav hlau, minerals) yuav raug daig hauv cov tee dej tsim.
Cov tee no nrog impurities ua conductive, thaum corona cov nyhuv ntawm high-voltage kab mus txog ob tee uas nyob ze txaus rau ib leeg, ib tug hluav taws xob arc tsim, generating tshav kub ntawm lawv thiab degrading lub tsho ntaub ntawm lub cable.
Cable tiv thaiv thiab cov ntaub ntawv tiv thaiv kev taug qab
Nws raug pom zoo kom siv cov ntaub ntawv los tiv thaiv thaum tsoADSS fiber ntau optic cablesnyob ib sab ntawm cov cuab yeej siv thiab cov chaw siv hluav taws xob muaj peev xwm ntawm 12 kV txog 25 kV.Cov no tuaj yeem tiv taus qhov cuam tshuam ntawm hluav taws xob tawm, txo cov teebmeem ntawm ionization, cua sov, thiab degradation ntawm cables.
Cov ntaub ntawv tiv thaiv kev taug qab tau muab faib ua ob pawg loj, cov ntaub ntawv A thiab cov khoom siv hauv chav kawm B:
Class A cov ntaub ntawv
Cov ntaub ntawv Class A yog cov uas ua tau raws li cov qauv kev tiv thaiv raws li qhov ntsuas hluav taws xob thiab cov pa phem tau sim raws li IEEE P1222 2011 tus qauv, qhov no suav tias yog "tus qauv" ntawm lub khw.
Class B cov ntaub ntawv
Class B cov ntaub ntawv yog cov uas tsis nyob rau hauv tus qauv, qhov no tsis tau txhais hais tias cov ntaub ntawv no tsis ua hauj lwm los tiv thaiv kev mus txog qhovtwg nyhuv, tab sis, theej, lawv yog tswj los ntawm tsis los yog tshwj xeeb tej yam kev mob txhais los ntawm cov chaw tsim tshuaj paus, txawm rau tshwj xeeb daim ntawv thov. lossis cov kev cai nruj dua, chav kawm no tuaj yeem txhais tau tias "kev cai".
Tswv yim rauADSS kabinstallations nyob rau hauv high-voltage yees
Kev npaj yog qhov tseem ceeb.Nws yog ib qho tsim nyog yuav tsum coj mus rau hauv tus account cov pa phem Performance index thiab installation voltage thaum ib tug self-supporting fiber optic cable yog nteg nyob rau hauv ib tug ntev-ntev, high-voltage ntauwd.Tsuav yog peb nyob hauv cov kev txwv tsim los ntawm IEEE P1222-2011 tus qauv, peb tuaj yeem siv cov khoom siv hauv chav kawm A, uas yog siv tau ntau dua hauv kev ua lag luam;rau ib puag ncig hnyav dua lossis muaj hluav taws xob ntau dua, nws yuav tsum siv cov khoom siv hauv chav kawm B.
Hu rau koj lub chaw tsim khoom cable kom paub meej cov khoom siv uas tuaj yeem siv los tiv thaiv kev ncaj ncees ntawm cable hauv koj qhov kev teeb tsa, ua tau raws li cov xwm txheej uas yuav raug nthuav tawm.
