Lub rwb thaiv tsev qauv ntawm kev siab - voltage switchgear tuaj yeem faib ua rwb thaiv tsev nyob rau hauv qhov chaw txee nyob sab hauv, nyob ntawm lawv qhov chaw nyob.
Cov rwb thaiv tsev feem ntau tshaj plaws nyob rau hauv qhov chaw txee yog huab cua, txhais tau tias huab cua yog siv los ua nruab nrab insulating rau ob qho chaw nyob thiab av, thiab theem nrab. Vim tias cov rwb thaiv tsev nyob deb ntawm theem nyob rau hauv ib tug roj av - muaj qhov loj me txo, lub tshuab hloov pauv loj yog txo. Yog li ntawd, piv rau cov pa - insulated Switchgear, kev pab cuam loj, thiab kho kom zoo dua qub circuits, yog li txhim kho kev nyab xeeb thiab kev ntseeg tau. Txawm li cas los xij, nws qhov tsis zoo yog tias kev siv SF6 roj tuaj yeem ua teeb meem ib puag ncig.
Rwb thaiv tsev ntawm cov khoom siv sab hauv feem ntau cuam tshuam cov khoom insulating ua los ntawm ceramic, yas, roj hmab, iav, thiab lwm yam ntaub ntawv. Piv txwv li, cov nkoj hauv lub tshuab nqus hluav taws xob, cov khoom tseem ceeb hauv Switchgear, siv iav lossis tej hub tawm ntawm chav tsev. Lub insulating cov cheebtsam ntawm lub tshuab nqus hluav taws xob feem ntau yog ua los ntawm 4330 iav fiber ntau txhawb phenolic compression rau hluav taws xob rwb thaiv tsev. Txawm li cas los xij, cov ntaub ntawv no muaj cov laus tsis kam thiab noo noo tsis kam, thiab nws cov rwb thaiv tsev muaj zog txo thaum siv. Yog li no, fiber ntau txhawb nqa polyester compressurated polyester compression moulding (SMC thiab DMC) tam sim no tau siv los ua kom muaj kev ncua deb thiab txhim kho kev ua haujlwm rwb thaiv tsev. Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, tshwj xeeb plastics tau nce qib thawj cov khoom siv rwb thaiv tsev hauv nruab nrab- voltage switchgear.
Txhawm rau muab tag nrho ua si rau qhov zoo ntawm ntau cov ntaub ntawv rwb thaiv tsev, cov thev naus laus zis uas sib xyaw ua ke, uas yog hu ua cov tshuab rwb thaiv tsev. Muaj ntau ntau hom:
(1) Puas rwb thaiv tsev thev naus laus zis nrog cov pa rwb thaiv tsev yog lub cev loj. Cov thev naus laus zis no siv cov pa hluav taws xob tseem ceeb thiab cov txheej txheem rwb thaiv tsev thiab cov txheej txheem resin rau ntawm txoj kev tso tawm kom luv luv. Cov ntawv thov cov ntaub ntawv raug suav nrog: Tso cov tshav kub tshav pob hluav taws xob rau ntawm cov tshuab hluav taws xob, thiab lwm yam ntawm cov thev naus laus zis yog tias cov kev sib tham ntawm kev tiv thaiv kev tiv thaiv kev tawm paug. Thov lub luag haujlwm nrog tib lub polarity raws li qhov hluav taws xob sib faib tuaj yeem txhim kho hluav taws xob teb thiab tau txais cov hluav taws xob ntxiv 1.5 zaug ntawm cov pa rwb thaiv tsev.
(2) Puas Rwb Thaiv Tsev Tshuab nrog Roj Rwb thaiv tsev yog lub cev loj. Tus rwb thaiv tsev sib xyaw nyob rau hauv qis - h siab sf6 roj ze rau cov atmospheric siab yog tib yam li cov pa roj. Ntxig cov tshuaj pheebsuab hauv kev tawm hauv txoj kev tawm tuaj yeem txhim kho hluav taws xob teb thiab nce cov hluav taws xob. Qhov sib txawv tsuas yog qhov kev faib tawm hauv SE6 roj yog cuam tshuam nrog cov duab ntawm kev faib tawm. Qhov nruab nrab - voltage switchgear tuaj yeem txo cov khoom ntim ntim rau 1/3 ntawm huab cua hloov los ntawm kev sib txuas SF6 roj thiab rwb thaiv tsev.
(3) cov khoom {{1} {{- Lub tshuab nqus tsev muaj cov tshuab thev naus laus zis. Cov yam ntxwv ntawm cov thev naus laus zis yog cov khoom siv hluav taws xob sab nraud, thiab cov chaw seem ntawm cov thawv ntim tau ntim nrog SF6 roj ntxiv. Los ntawm cov qauv no, qhov ntim ntawm tus hloov chaw tuaj yeem txo mus rau 1/3 ntawm qhov ntawm huab cua ntshiab.
Yog li, yuav ua li cas txhawm rau txhawm rau txhim kho cov rag thaiv cov qib siab ntawm qhov siab - voltage switchgear?Muaj feem ntau ntsuas:
(1) Nco ntsoov tias cov huab cua ntshiab ua tau raws li qhov yuav tsum tau ua. Rau 10KV Switchgear nrog cov pa rwb thaiv tsev, qhov kawg cua sib txawv ntawm theem thiab rau hauv av yuav tsum tsis pub tsawg tshaj 125mm; Cov cua sib txawv ntawm tus thawj coj thiab kev faib tawm cov insulit yuav tsum tsis pub tsawg tshaj li 30mm.
(2) tsim kho kho cov rwb thaiv tsev sab nraud kom deb li deb. Cov phiaj xwm tsim nyog plooj me nyuam yog lub hauv paus rau cov phiaj hniav los tiv thaiv kev qias neeg. Tus rwb thaiv tsev sab nraud sab nraud yuav tsum yog tsim nyog tau teeb tsa raws li cov kev ua qias tuaj hauv thaj chaw. Rau sab hauv tsev hloov chaw ua haujlwm hauv kev hws thiab cov khoom muaj kuab paug nyob rau hauv cov ntaub ntawv tsis tu ncua yog 18 hli / kv rau cov ntaub ntawv organic thiab 20mm / kV rau cov ntaub ntawv organic.
(3) Xaiv cov khoom siv nrog cov khoom siv rwb thaiv tsev zoo. Cheebtsam nrog cov khoom siv rwb thaiv tsev zoo yuav tsum tau xaiv, tshwj xeeb tshaj plaws hloov hluav taws xob. Lawv volt - Cov yam ntxwv amperistics yuav tsum ua kom tau raws li qhov yuav tsum muaj qhov tsis muaj kev ua haujlwm tseem ceeb hauv qab cov kab hluav taws xob. Raws li txoj kev sib txuas, nws yog qhov zoo tshaj plaws tsis txuas rau ib lossis ob theem hluav taws xob hloov pauv ntawm cov ntu ntawm cov av thiab tsis txhob nruab nrab ntawm lub chaw lossis resonance.
(4) Siv interrath insulating partitions rau trolley {{1} kev daws teeb meem, yog tias daws tau qhov kev daws teeb meem, qhov kev daws teeb meem yuav tuaj yeem txhim kho intervhase partitions. Cov tshuaj insulating siv yuav tsum muaj cov nplaum nplaum ua ntu zus, thiab lawv cov ntaub ntawv yog: ① Epoxy Resin Laminated iav daim ntaub board ua los ntawm cov hluav taws xob cua ua los ntawm hluav taws xob cua sov thiab kho hluav taws xob cua sov thiab kho hluav taws xob thiab kho hluav taws xob thiab kho hluav taws xob thiab kho hluav taws xob thiab kho hluav taws xob; ② DMC thiab SMC tsis tau lav Polyester Iav Fiber ntau txhawb cov khoom yas.
(5) Ua cov rwb thaiv tsev rwb thaiv cov rwb thaiv cov rwb thaiv tsev rwb thaiv tsev ntawm cov chaw busbar ntawm txhua qhov hloov. Thaum muaj kev sib tsoo tshwm sim nyob rau hauv ib qho kev sib tsoo, kev sib tsoo tuaj yeem raug kaw rau kev sib tsoo txee, yog li txo qis kev poob. Qhov thib ob, sealing thiab cais cov chav nyob ntawm cov chaw hloov hluav taws xob ntawm cov hloov kuj yog qhov ntsuas tau zoo los txwv qhov kev sib tsoo. Rau lub busbar, cov nplaim taws {4 4}} retardant tshav kub {}} shrinkable insulating rasulating Raj teeb tuaj yeem siv tau. Arc - tiv taus thiab nplaim taws- retever insulating lub rooj zaum los tiv thaiv qhov tshwm sim ntawm "hluav taws kub lub yeej" kev raug xwm txheej. Hauv qab ntawm lub txee yuav tsum tau kaw kom nruj me ntsis los tiv thaiv cov tsiaj me los ntawm kev tso dej tsaws chaw thiab ua rau hauv av lossis cuam tshuam luv luv hluav taws xob. Thawj cais tawm ntawm lub tuam txhab Trolley yuav tsum tau them nrog cov npog insulating. Thaum lub trolley tawm lub txee rau, ib qho insulating baffle yuav tsum tau cais cov chaw sib chwv ntawm cov neeg ua haujlwm zoo nkauj los tiv thaiv kev ua haujlwm los ntawm kev ua kom muaj hluav taws xob. Ib daim ntaub thaiv insulating kuj tseem siv tau, tab sis tom qab Trolley hloov yog thawb mus rau txoj haujlwm ua haujlwm, cov huab cua sib txawv ntawm lub neej thiab ntawm lub qhov (socket) yuav tsum muaj ntau dua 30 hli. Txawm li cas los xij, qhov no ua rau cov qib ntawm kev sib khi ntawm cov compartments.
(6) siv tag nrho cov ntaub ntawv insulating. Rau insulating partitions, insulating cov ntaub ntawv nrog cov rwb thaiv tsev zoo, tsis - hygroscopicity yuav tsum tau xaiv. Ntxiv nplaim - retardant kub ntsws tub rog thiab lwm tus neeg coj tuaj yeem txhim kho qib rwb thaiv tsev ntawm lawv cov cua. Tsis tas li ntawd, kev siv ntawm ib qho {{}}}}} reetrically rwbing tiab yog tseem muaj kev ntsuas zoo los txhim kho qib rwb thaiv tsev ntawm hloov lub txee.
(7) Tswj thiab txhim kho qhov chaw ua haujlwm. Cov kev tswj hwm thiab kev txhim kho ntawm kev ua haujlwm ib puag ncig yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov hloov chaw. Cov khoom siv hloov yuav tsum ua raws li txoj ntsiab cai ntawm "kev tu txhua zaus nws nres". Hloov chav nrog cov av noo muaj peev xwm txais yuav cov kev ntsuas xws li cua sov thiab txhim kho dehumiders kom txhim kho ib puag ncig hloov.
