Hauv kev ua haujlwm hluav taws xob, kev xaiv cov xov hluav taws xob siab thiab qis yog qhov tseem ceeb heev kom ntseeg tau tias muaj kev nyab xeeb, ua haujlwm tau zoo thiab txhim khu kev qha. Kev nkag siab txog qhov sib txawv tseem ceeb ntawm ob hom xov hluav taws xob no tuaj yeem pab cov engineers, cov kws kho hluav taws xob, thiab cov thawj coj ua haujlwm txiav txim siab zoo rau lawv cov ntawv thov tshwj xeeb.
Kev txhais thiab qhov voltage ntau yam
Cov xov hluav taws xob siabyog tsim los nqa tam sim no ntawm cov voltages feem ntau siab tshaj 1,000 volts (1 kV). Cov cables no yog qhov tseem ceeb rau kev xa hluav taws xob hla kev deb, xws li los ntawm cov chaw tsim hluav taws xob mus rau cov chaw hloov pauv lossis ntawm cov chaw hloov pauv thiab cov tes hauj lwm faib khoom. Cov ntawv thov feem ntau suav nrog cov kab hluav taws xob saum toj kawg nkaus thiab cov kab ke xa hluav taws xob hauv av.
Cov xov hluav taws xob tsawg, ntawm qhov tod tes, ua haujlwm ntawm qhov hluav taws xob qis dua 1,000 volts. Lawv feem ntau siv rau hauv teeb pom kev zoo, faib hluav taws xob thiab tswj cov kab ke hauv tsev, chaw ua lag luam thiab chaw ua haujlwm. Piv txwv li, cov xov hluav taws xob siv rau hauv cov xov hluav taws xob hauv tsev, cov voj voog teeb pom kev zoo thiab cov tshuab me me.
Kev tsim kho thiab cov ntaub ntawv
Cov qauv ntawm cov xov hluav taws xob siab muaj ntau dua li cov xov hluav taws xob qis. Cov xov hluav taws xob siab feem ntau muaj ntau txheej, suav nrog cov hlau conductors, insulators, shields thiab sheaths sab nraud. Cov ntaub ntawv rwb thaiv tsev yog qhov tseem ceeb los tiv thaiv kev xau thiab xyuas kom muaj kev nyab xeeb. Cov ntaub ntawv rwb thaiv tsev feem ntau siv hauv cov xov hluav taws xob siab suav nrog cross-linked polyethylene (XLPE) thiab ethylene-propylene roj hmab (EPR).
Cov xov hluav taws xob tsawg feem ntau yooj yim dua hauv kev tsim, txawm hais tias lawv tseem xav tau cov ntaub ntawv zoo. Lawv feem ntau yog insulated siv PVC (polyvinyl chloride) lossis roj hmab, uas txaus rau qhov ntsuas hluav taws xob qis dua. Cov ntaub ntawv conductor tuaj yeem sib txawv, tab sis tooj liab thiab txhuas yog cov kev xaiv feem ntau rau kev siv hluav taws xob siab thiab qis.
Kev ua tau zoo thiab kev ruaj ntseg
Cov xov hluav taws xob siabtau tsim los kom tiv taus cov xwm txheej hnyav, suav nrog qhov kub thiab txias siab, kev ntxhov siab ntawm lub tshuab thiab cov yam ntxwv ib puag ncig. Lawv feem ntau raug kuaj xyuas lub zog dielectric, uas ntsuas lub peev xwm ntawm cov xov hlau los tiv taus kev tawg hluav taws xob. Qhov no yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub kaw lus xa hluav taws xob.
Qhov sib txawv, cov xov hluav taws xob qis yog tsim los rau cov chaw uas tsis tas siv zog ntau. Txawm hais tias lawv tseem yuav tsum ua raws li cov qauv kev nyab xeeb, cov kev cai ua haujlwm tsis nruj npaum li cov xov hluav taws xob siab. Txawm li cas los xij, cov xov hluav taws xob qis tseem yuav tsum ua raws li cov cai hluav taws xob hauv zos thiab cov cai kom ntseeg tau tias kev ua haujlwm muaj kev nyab xeeb.
Daim Ntawv Thov
Cov kev siv ntawm cov xov hluav taws xob siab thiab cov xov hluav taws xob qis yog txawv heev. Cov xov hluav taws xob siab feem ntau yog siv rau hauv kev tsim hluav taws xob, kev sib kis thiab kev faib hluav taws xob. Lawv yog qhov tseem ceeb rau kev txuas cov chaw siv hluav taws xob rov ua dua tshiab xws li cua thiab hnub ci ua liaj ua teb rau lub network.
Txawm li cas los xij, cov xov hluav taws xob qis muaj nyob txhua qhov chaw hauv lub neej txhua hnub. Lawv siv rau hauv cov xov hluav taws xob hauv tsev, cov tsev lag luam thiab cov chaw ua haujlwm kom teeb pom kev zoo, cua sov thiab muab hluav taws xob rau ntau yam khoom siv. Lawv qhov kev hloov pauv ua rau lawv haum rau ntau yam kev siv, los ntawm cov voj voog yooj yim hauv tsev mus rau cov kab ke tswj hwm nyuaj hauv cov chaw tsim khoom.
xaus lus
Hauv kev xaus lus, kev xaiv cov xov hluav taws xob siab thiab qis nyob ntawm qhov xav tau tshwj xeeb ntawm lub tshuab hluav taws xob cuam tshuam. Cov xov hluav taws xob siab yog qhov tseem ceeb rau kev xa hluav taws xob zoo mus deb, thaum cov xov hluav taws xob qis yog qhov tseem ceeb rau kev siv hluav taws xob txhua hnub. Kev nkag siab txog qhov sib txawv tseem ceeb hauv kev tsim kho, kev ua tau zoo, thiab kev siv tuaj yeem pab cov kws tshaj lij txiav txim siab kom paub tseeb tias muaj kev nyab xeeb thiab kev ntseeg siab ntawm lawv cov tshuab hluav taws xob. Txawm hais tias koj tab tom tsim lub network hluav taws xob tshiab lossis kev txuas hluav taws xob hauv tsev, kev paub thaum twg yuav tsum siv cov xov hluav taws xob siab thiab qis yog qhov tseem ceeb rau kev vam meej.
