Raws li ib feem tseem ceeb ntawm kev xa hluav taws xob, cov kab hluav taws xob dav hlau ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob thoob ntiaj teb. Tshwj xeeb tshaj yog nyob rau hauv teb chaws Australia, nrog rau kev loj hlob tsis tu ncua ntawm lub hwj chim xav tau, overhead cables tau maj mam dhau los ua txoj kev nyiam ntawm kev xa hluav taws xob hauv nroog, suburbs thiab thaj chaw deb. Raws li cov khoom siv hluav taws xob siv hluav taws xob sib txuas, Australian tus qauv hluav taws xob sib luag kab hluav taws xob (Aerial Parallel Cable) tau siv dav hauv kev tsim kho cov hluav taws xob nruab nrab thiab qis hluav taws xob vim nws cov kev ua haujlwm siab, kev lag luam thiab kev ruaj ntseg. Tsab ntawv xov xwm no yuav tham txog kev tsim thiab kev siv ntawm Australian tus qauv sib npaug ntawm cov kab hluav taws xob nyob rau hauv kom meej los ntawm ob qho tib si theoretical thiab cov tswv yim, suav nrog cov ntsiab lus xws li Aerial Parallel Cable, Aerial Cable, Parallel Cable thiab Aerial Cable 0.6/1KV.
1. Lub tswv yim yooj yim thiab kev txhim kho ntawm Aerial Cable
Aerial Cable hais txog cov kab xa hluav taws xob uas tau muab tso rau hauv huab cua. Piv nrog rau cov kab hluav taws xob hauv av ib txwm muaj, cov kab hluav taws xob dav hlau muaj qhov zoo ntawm kev teeb tsa yooj yim, kev saib xyuas yooj yim thiab tus nqi qis, yog li lawv tau siv dav hauv kev xa hluav taws xob hauv nroog thiab hauv nroog. Aerial cables feem ntau yog tsim los ntawm ntau qhov chaw xws li conductors, rwb thaiv tsev txheej, thiab sab nrauv sheaths. Cov khoom siv hluav taws xob feem ntau yog tooj liab lossis txhuas, uas muaj qhov zoo conductivity.
Hauv Australia, daim ntawv thov ntawm cov cables overhead muaj keeb kwm ntev. Nrog kev txhim kho txuas ntxiv ntawm lub zog hluav taws xob, kev tsim thiab thev naus laus zis ntawm cov khoom siv hluav taws xob tau txuas ntxiv thiab txhim kho. Tshwj xeeb tshaj yog nyob rau hauv kev tsim ntawm ** parallel aerial cables (Aerial Parallel Cable) **, niaj hnub fais fab tshuab muaj ntau zog yuav tsum tau rau cables, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm kub tsis kam, siab tsis kam, thiab corrosion kuj, uas tau maj mam nce qib ntawm overhead. cable technology.
2. Tsim cov ntsiab lus ntawm Australian tus qauv parallel aerial cables
Parallel aerial cables, raws li lub npe qhia, xa mus rau kev xa hluav taws xob los ntawm cable conductors teem rau tib lub sijhawm. Nws tsim yog txawv los ntawm cov tsoos nyiaj siv ua haujlwm cables, feem ntau yog reflected nyob rau hauv cov qauv ntawm ntau yam conductors teem nyob rau hauv parallel. Qhov kev tsim no tuaj yeem txhim kho kev ruaj ntseg ntawm cov cable thiab txo qhov tshwm sim ntawm lub zog hluav taws xob tsis ua haujlwm thaum ua kom muaj kev sib kis tau zoo.
2.1 Cov ntaub ntawv tus neeg xyuas pib thiab kev ua haujlwm cable
Hauv tebchaws Australia, cov conductors ntawm Aerial Parallel Cable feem ntau yog ua los ntawm txhuas lossis tooj liab. Aluminium conductors feem ntau yog siv rau cov hluav taws xob qis thiab nruab nrab-voltage kis tau tus mob vim lawv lub teeb yuag thiab tus nqi qis. Copper conductors yog tsim rau high-voltage fais fab kis tau tus mob vim lawv zoo conductivity. Cov kev qhia tshwj xeeb thiab cov ntaub ntawv ntawm tus neeg xyuas pib cuam tshuam ncaj qha rau kev ua haujlwm hluav taws xob ntawm lub cable, suav nrog nws lub peev xwm kis tau tus mob, qhov kub tsis kam, thiab muaj peev xwm tiv thaiv hluav taws xob tsis raug.
2.2 Cov ntaub ntawv rwb thaiv tsev thiab kev tiv thaiv tsim
Australia cov kab hluav taws xob sib txuas feem ntau siv ** polyethylene (PE) lossis cross-linked polyethylene (XLPE) ua cov ntaub ntawv rwb thaiv tsev. Hla-txuas polyethylene yog dav siv nyob rau hauv ntau yam sab nraum zoov overhead cables vim nws zoo heev tiv taus kub, UV hluav taws xob thiab tshuaj corrosion. Rau cov tshuab hluav taws xob tsawg thiab nruab nrab, polyethylene yog qhov kev xaiv zoo dua thiab siv tau. Txhawm rau txhim kho cov kav ntev ntawm lub cable, lub tsho sab nrauv feem ntau yog ua los ntawm polyvinyl chloride (PVC) lossis polyethylene (PE) ** cov ntaub ntawv, uas tuaj yeem tiv thaiv ib puag ncig sab nraud los ntawm kev puas tsuaj rau cable, xws li kev puas tsuaj, hluav taws xob ultraviolet. thiab nag.
2.3 Kev ua haujlwm hluav taws xob thiab qib voltage
Raws li kev xav tau ntawm kev xa hluav taws xob, cov kab hluav taws xob overhead hauv Australia muaj qhov sib txawv voltage. Cov kab hluav taws xob siv hluav taws xob ntau muaj qhov voltage ntawm 0.6/1KV, uas yog siv rau kev xa hluav taws xob tsawg thiab nruab nrab-voltage. Rau cov ntawv thov uas xav tau kev xa hluav taws xob ntau dua, cov khoom siv hluav taws xob siv hluav taws xob nrog cov qib siab voltage xws li 35KV kuj tuaj yeem siv. Qhov voltage theem ntawm lub cable yog ze ze rau cov specifications ntawm nws cov neeg xyuas pib, thickness ntawm cov ntaub ntawv rwb thaiv tsev thiab tag nrho cov tsim ntawm cable. Hauv kev siv cov tswv yim, cov neeg tsim qauv yuav xaiv cov qauv tsim nyog cable thiab cov lus qhia tshwj xeeb raws li qhov sib txawv ntawm cov kev xav tau ntawm lub zog xa mus thiab qhov deb.
3. Daim ntawv thov thaj chaw ntawm Australian tus qauv parallel overhead cables
Aerial Parallel Cable muaj ntau yam kev siv hauv Australia, suav nrog ntau lub zog xa hluav taws xob los ntawm cov nroog mus rau cov chaw nyob deb nroog thiab los ntawm qhov tsis tshua muaj hluav taws xob mus rau qhov siab. Parallel overhead cables tuaj yeem tsis tsuas yog ua tau raws li kev xav tau ntawm lub zog txhua hnub, tab sis kuj hloov mus rau kev xa hluav taws xob hauv qee qhov chaw tshwj xeeb.
3.1 Kev xa hluav taws xob hauv nroog thiab thaj chaw muaj kev lag luam
Aerial cables yog dav siv nyob rau hauv lub hwj chim faib systems nyob rau hauv lub nroog thiab industrial cheeb tsam. Raws li Urban lub zog hluav taws xob feem ntau yog feem ntau ntom thiab txoj kev teeb tsa ntawm cov neeg siv nyiaj ua haujlwm tsis yog yooj yim thiab muaj nyiaj txiag, tab sis kuj yooj yim tswj. Tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas yuav tsum tau loj-muaj peev xwm kis tau tus mob, 0.6/1KV parallel overhead cables yuav muab npaum thiab ruaj khov fais fab mov.
3.2 Cov khoom siv hluav taws xob hauv cov chaw nyob deb nroog thiab thaj chaw deb
Aerial cables yog tshwj xeeb tshaj yog haum rau tej thaj chaw deb thiab nyob deb nroog hauv Australia. Piv nrog rau hauv av cables, overhead cables tsis tsuas yog txo nqi installation, tab sis kuj yuav yooj yim dua tiv nrog complex struts tej yam kev mob. Hauv qee qhov chaw uas muaj rugged struts, overhead cables tuaj yeem hla cov teeb meem xws li roob thiab dej ntws los ntawm kev teeb tsa lub zog xa hluav taws xob los xyuas kom muaj kev ruaj ntseg ntawm lub zog hluav taws xob.
3.3 Kev nkag mus rau cua thiab hnub ci fais fab nroj tsuag
Raws li lub zog ntawm kev tsim hluav taws xob tauj dua tshiab hauv Australia nrawm dua, kev tsim kho cua thiab hnub ci fais fab nroj tsuag tau maj mam nce. Nyob rau hauv tus txheej txheem ntawm lub hwj chim nkag mus rau cov fais fab nroj tsuag, nyiaj siv ua haujlwm cables feem ntau yog siv los xa hluav taws xob los ntawm cov tshuab hluav taws xob mus rau hauv daim phiaj loj. Aerial Parallel Cable tau dhau los ua cov cable nyiam rau lub sijhawm no vim nws tus nqi qis thiab muaj zog yoog raws.
4. Kev teeb tsa thiab kev saib xyuas ntawm Aerial Cable 0.6/1KV
4.1 Installation yuav tsum
Thaum txhim kho Aerial Cable 0.6/1KV, qee qhov kev xav tau thiab kev teeb tsa tshwj xeeb yuav tsum ua raws. Ua ntej, kev tso cov nyiaj siv ua haujlwm yuav tsum xav txog qhov khoov lub vojvoog ntawm cov kab hluav taws xob kom tsis txhob cuam tshuam ntau dhau ntawm cov cable thiab kev puas tsuaj rau cov txheej txheem rwb thaiv tsev. Qhov thib ob, qhov verticality thiab parallelism ntawm lub cable yuav tsum tau ua kom ntseeg tau thaum lub sijhawm teeb tsa kom tsis txhob muaj kev ntxhov siab sab nraud ntawm lub cable. Rau cov kab hluav taws xob ntev ntev, nws yog ib qho tsim nyog yuav tsum xyuas kom muaj kev nyab xeeb ntawm cov kab hluav taws xob los ntawm kev teeb tsa cov hlua khi thiab cov hlua khi.
4.2 Kev tu thiab tshuaj xyuas
Kev saib xyuas thiab tshuaj xyuas cov kab hluav taws xob overhead kuj tseem ceeb heev. Tsis tu ncua xyuas seb lub plhaub sab nraud thiab cov txheej txheem rwb thaiv tsev ntawm lub cable puas muaj cov kab nrib pleb, hnav thiab lwm yam kev puas tsuaj. Yog tias lub cable ntsib kev puas tsuaj rau lub cev sab nraud, nws yuav ua rau lub zog tsis ruaj khov thiab txawm tias muaj kev nyab xeeb xws li luv luv Circuit Court. Yog li ntawd, rau kev saib xyuas ntawm cov nyiaj siv ua haujlwm cables, tsis yog tsuas yog yuav tsum tau kuaj xyuas tsis tu ncua, tab sis tseem yuav tsum tau hloov lub sijhawm ntawm cov khoom siv cable puas los xyuas kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub zog hluav taws xob.
