Cov khoom siv hluav taws xob tuaj yeem muaj ntau qhov ntau thiab tsawg, cov duab, cov ntaub ntawv, thiab cov qauv tsim.Txawm hais tias lawv txhua tus muaj tib lub hom phiaj hauv siab - los tiv thaiv cov khoom siv hluav taws xob los ntawm ib puag ncig, tiv thaiv cov neeg siv hluav taws xob poob siab, thiab txhim kho cov khoom siv hluav taws xob - lawv tuaj yeem sib txawv heev.Yog li ntawd, cov kev xav tau ntawm cov khoom siv hluav taws xob tau cuam tshuam los ntawm kev xav tau ntawm cov neeg siv khoom.
Thaum peb tham txog kev lag luam uas yuav tsum tau muaj rau cov khoom siv hluav taws xob, peb feem ntau tham txog cov qauv es tsis yog cov cai yuav tsum tau ua (piv txwv li, cov cai).Cov qauv no pab txhawb kev sib txuas lus ntawm cov tuam ntxhab thiab cov neeg siv khoom.Lawv kuj tawm tswv yim rau kev nyab xeeb, tsim kom muaj txiaj ntsig, thiab kev ua haujlwm siab.Niaj hnub no, peb yuav dhau los ntawm qee cov qauv kev kaw lus uas muaj ntau tshaj plaws, nrog rau qee qhov kev txhawj xeeb tseem ceeb ntawm cov tib neeg muaj thaum xaj lub txee hluav taws xob lossis lub txee.
Common Standards For Enclosures
Feem ntau cov tuam ntxhab ntawm cov khoom siv hluav taws xob ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb los ntawm lub koom haum muaj npe nrov npe.Hauv Tebchaws Meskas, Underwriters Laboratories (UL), National Electrical Manufacturers Association (NEMA), thiab Intertek yog peb lub koom haum sau npe loj.Ntau lub tuam txhab siv lub International Electrotechnical Commission ntawm lub ntiaj teb no teev (IEC), uas teev ib tsev neeg ntawm cov qauv rau hluav taws xob enclosures, thiab lub koom haum ntawm hluav taws xob thiab Electronics Engineers (IEEE), ib tug kws tshaj lij lub koom haum uas teev cov qauv rau kev nce qib technology thiab pab tib neeg. .
Peb cov qauv hluav taws xob feem ntau yog luam tawm los ntawm IEC, NEMA, thiab UL, raws li tau hais dhau los.Koj yuav tsum sab laj nrog cov ntawv tshaj tawm NEMA 250, IEC 60529, thiab UL 50 thiab 50E.
IEC 60529 (TSI)
Cov qib kev tiv thaiv ingress raug txheeb xyuas siv cov lej no (tseem hu ua Tus Qauv Zauv) (tseem hu ua IP kev ntsuas).Lawv txhais tau hais tias lub kaw lus zoo tiv thaiv nws cov ntsiab lus los ntawm ya raws, plua plav, grime, tib neeg, thiab lwm yam khoom.Txawm hais tias tus qauv tso cai rau kev kuaj tus kheej, ntau lub tuam txhab nyiam kom muaj lawv cov khoom ntawm nws tus kheej sim rau kev ua raws.
TIAB SA 250
NEMA muab kev tiv thaiv ingress zoo ib yam li IEC ua.Nws ua li cas los xij, suav nrog kev tsim kho (tus qauv tsim tsawg kawg), kev ua tau zoo, kev sim, corrosion, thiab lwm yam.NEMA faib cov ntaub thaiv npog raws li lawv Hom es tsis yog lawv qhov ntsuas IP.Nws kuj ua rau kev ua raws li tus kheej, uas tshem tawm qhov xav tau rau kev kuaj xyuas lub Hoobkas.
UL 50 thiab 50E
UL cov qauv yog raws li NEMA specifications, tab sis lawv kuj yuav tsum tau kuaj thib peb thiab nyob rau ntawm qhov chaw soj ntsuam xyuas kom ua raws li.Ib lub tuam txhab cov qauv NEMA tuaj yeem ua pov thawj nrog UL ntawv pov thawj.
Ingress tiv thaiv yog hais nyob rau hauv tag nrho peb cov qauv.Lawv ntsuam xyuas lub qhov rooj muaj peev xwm tiv thaiv qhov nkag ntawm cov khoom (xws li hmoov av) thiab kua (xws li dej).Lawv kuj coj mus rau hauv tus account tib neeg kev tiv thaiv los ntawm enclosure cov khoom txaus ntshai.
Lub zog, sealing, khoom siv / tiav, latching, flammability, qhov cua, mounting, thiab thermal tiv thaiv yog tag nrho cov them los ntawm UL thiab NEMA enclosure tsim qauv.Bonding thiab grounding kuj tau hais los ntawm UL.
Qhov tseem ceeb ntawm Cov Qauv
Cov neeg tsim khoom thiab cov neeg siv khoom tuaj yeem sib txuas lus tau yooj yim txog cov khoom lag luam zoo, cov yam ntxwv, thiab qib kev ua haujlwm zoo ua tsaug rau cov qauv.Lawv txhawb kev nyab xeeb thiab txhawb cov tuam txhab tsim khoom kom ua tau zoo thiab ua tiav cov qauv kev ua tau zoo.Qhov tseem ceeb tshaj plaws, lawv pab cov neeg siv hauv kev paub txog kev xaiv kom lawv tuaj yeem xaiv cov ntaub ntawv uas haum rau lawv daim ntawv thov cov cai tshwj xeeb.
Yuav muaj ntau qhov sib txawv ntawm cov khoom tsim thiab kev ua haujlwm yog tias tsis muaj cov qauv nruj.Tsis txhob tsom mus rau qhov tau txais tus nqi qis tshaj plaws, peb txhawb kom txhua tus neeg siv khoom xav txog cov qauv kev lag luam thaum tau txais cov ntaub ntawv tshiab.Kev ua tau zoo thiab kev ua tau zoo yog qhov tseem ceeb tshaj li tus nqi hauv lub sijhawm ntev.
Cov neeg siv khoom xav tau
Vim tias cov chaw tsim hluav taws xob tsuas yog yuav tsum tau ua kom tiav qee qhov kev xav tau (lawv cov qauv), feem ntau ntawm cov khoom siv hluav taws xob xav tau los ntawm cov neeg siv khoom.Dab tsi nta cov neeg muas zaub xav tau nyob rau hauv ib qho hluav taws xob enclosure?Lawv txoj kev xav thiab kev txhawj xeeb yog dab tsi?Thaum tab tom nrhiav lub txee tshiab los tuav koj cov khoom siv hluav taws xob, koj yuav tsum nrhiav dab tsi?
Xav txog cov kev xav hauv qab no thaum ua koj daim ntawv teev npe ntawm cov kev xav tau thiab kev nyiam yog tias koj xav tau ib lub thawv hluav taws xob:
Cov ntaub thaiv npog
Cov ntaub thaiv npog yog ua los ntawm ntau yam ntaub ntawv, suav nrog hlau, yas, fiberglass, tuag-cam khwb cia, thiab lwm yam.Xav txog qhov hnyav, kev ruaj ntseg, nqi, kev xaiv mounting, saib, thiab kav ntev ntawm koj cov kev xaiv thaum koj tshawb nrhiav lawv.
Kev tiv thaiv
Ua ntej koj yuav khoom, saib dhau NEMA cov qhab nia, uas qhia cov khoom qib ntawm kev tiv thaiv ib puag ncig.Vim tias cov kev ntsuas no qee zaum nkag siab yuam kev, tham nrog cov chaw tsim khoom / tus muag khoom txog koj cov kev xav tau ua ntej.NEMA kev ntsuam xyuas tuaj yeem pab koj txheeb xyuas yog tias lub kaw lus tsim nyog rau kev siv sab hauv thiab sab nraud.seb nws puas tuaj yeem tiv thaiv cov dej ingress, seb nws puas tuaj yeem tiv thaiv kev tsim cov dej khov, thiab ntau ntxiv.
Mounting thiab Orientation
Mounting thiab Orientation: Koj lub qhov rooj puas puas yog phab ntsa-mounted lossis sawv ntsug?Puas yuav lub qhov rooj yuav vertically lossis horizontally oriented?Xyuas kom lub enclosure koj xaiv ua tau raws li cov kev cai yooj yim logistical.
Loj
Xaiv qhov loj me me yuav tshwm sim ncaj nraim, tab sis muaj ntau qhov ua tau.Yog tias koj tsis ceev faj, koj tuaj yeem "overbuy," yuav ntau dua li qhov koj xav tau.Txawm li cas los xij, yog tias koj cov ntaub ntawv pov thawj me me dhau lawm yav tom ntej, koj yuav tau hloov kho dua tshiab.Qhov no yog qhov tseeb tshwj xeeb yog tias koj qhov chaw nyob yuav xav tau kom haum rau yav tom ntej technologies.
Climate Control
Thaum tshav kub kub sab hauv thiab sab nrauv tuaj yeem ua mob rau cov khoom siv hluav taws xob, yog li kev tswj hwm huab cua yog qhov tseem ceeb.Tej zaum koj yuav tau tshawb xyuas cov txheej txheem hloov hluav taws xob raws li kev tsim hluav taws xob ntawm koj cov khoom siv thiab nws qhov chaw sab nraud.Nws yog ib qho tseem ceeb uas yuav tau xaiv lub tshuab cua txias kom raug rau koj lub qhov rooj.
Xaus
