Thaum cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob xav tau rau kev tswj vaj huam sib luag yog qhov tseem ceeb ntawm koj qhov kev tsim ua haujlwm, kev kwv yees lossis ncua sij hawm xaiv ntawm ib qho chaw tsim nyog tuaj yeem ua rau muaj teeb meem loj uas tuaj yeem zam tau nrog kev xav me ntsis. Txuag koj tus kheej kom mob taub hau los ntawm kev xav txog cov ntsiab lus tseem ceeb ua ntej. Yam khoom siv hluav taws xob twg yuav tsum siv?
Kev tshawb nrhiav hauv Google sai rau "hluav taws xob enclosures" tau txais 58 lab cov txiaj ntsig, yog li nws tsis xav tsis thoob tias qee tus kws tshaj lij yuav xav tias muaj kev ntxhov siab me ntsis los ntawm txoj haujlwm. Rau feem ntau cov ntawv thov, muaj kev daws teeb meem zoo kawg nkaus - qhov tseeb. Nws yog qhov zoo tshaj plaws los nrhiav kev txhawb nqa los ntawm koj tus neeg muab khoom kaw thaum xav tau, tab sis koj yuav tsum paub qee cov ntaub ntawv tseem ceeb los txiav txim siab qhov tsim nyog. Muaj ntau yam uas tuaj yeem cuam tshuam rau kev xaiv ntawm ib lub thawv rau ib daim ntawv thov tshwj xeeb. Peb yuav tsom mus rau xya qhov kev txiav txim siab rau cov khoom siv hluav taws xob.
1. qib kev tiv thaiv
2. Daim ntawv pov thawj thiab kev pom zoo
3. qhov loj
4. Cov kev cai nkag

Qib ntawm kev tiv thaiv
Cov chav kawm tiv thaiv ntawm ib lub thawv ntawv qhia tias lub qhov rooj tiv thaiv cov cuab yeej sab hauv zoo npaum li cas. Cov ntaub thaiv npog raug ntsuas raws li lawv lub peev xwm los tiv thaiv qhov nkag ntawm ntau theem ntawm plua plav thiab kua. Cov kev tiv thaiv kev ntsuas no feem ntau hu ua "hom" lossis "NEMA" (National Electrical Manufacturers Association) kev ntaus nqi.
Daim ntawv pov thawj thiab kev pom zoo
Cov koom haum Standards tau tsim kev ntsuas ntsuas rau kev ua tau zoo ntawm cov khoom sib txawv. Pawg ntawm cov khoom siv hluav taws xob tau txhais los ntawm cov koom haum xws li NEMA, CSA, UL thiab IEC los txiav txim siab lub peev xwm ntawm lub qhov rooj nkag los muab kev tiv thaiv plua plav, dej ntws, hose-shot dej, thiab lwm yam.
Txawm hais tias tag nrho cov qauv no tau tsim los coj cov neeg siv hauv kev xaiv cov khoom tsim nyog, muaj qee qhov sib txawv tseem ceeb ntawm lawv.
Hauv North America, NEMA, UL thiab CSA yog cov koom haum feem ntau pom zoo. Lawv zoo ib yam nyob rau hauv lawv cov kev ntsuam xyuas thiab kev ntsuam xyuas ntawm enclosures.
UL thiab CSA xav tau cov ntaub thaiv npog los kuaj hauv cov chaw kuaj pom zoo los ua pov thawj lawv qhov kev ua tau zoo. Lawv tsis tu ncua tshuaj xyuas cov tuam txhab lag luam kom ntseeg tau tias lawv siv cov ntaub ntawv pom zoo thiab tsim cov khoom raws li cov khoom lag luam kuaj yav dhau los. Nyob rau hauv lem, lawv muab ib tug "daim ntawv pov thawj daim ntawv lo" uas yog mus tas li affixed rau hauv lub enclosure.
Thaum NEMA kev ntsuam xyuas yog ib qho kev siv ib txwm, tsis zoo li UL / CSA, lub koom haum no tsis muab cov kev pabcuam kuaj, lawv tso kev ua raws thiab kev sim rau cov neeg tsim khoom txiav txim siab thiab lawv tsis muab 'daim ntawv pov thawj' rau cov ntaub thaiv npog.
Hauv Tebchaws Europe, IEC qhov ntsuas yog qhov feem ntau lees paub tus qauv rau cov ntaub thaiv npog. Qhov ntsuas IEC zoo ib yam li NEMA tab sis nrog cov kev cai sib txawv kom dhau los yog ua tsis tiav. IEC feem ntau txhawj xeeb txog kev tiv thaiv kev nkag thiab tsis suav nrog cov kev ntsuas tshwj xeeb rau cov ntaub thaiv npog hauv corrosive, xeb, roj, dej khov lossis tawg (muaj kev phom sij) ib puag ncig.
Qhov ntev
Qhov no yog qhov yooj yim, tab sis xav txog qhov tsawg kawg nkaus qhov loj ntawm lub thawv uas yuav tsum tau ua kom haum rau txhua qhov kev teeb tsa - piv txwv li, qhov sib sib zog nqus tob npaum li cas? Tom qab ntawd, paub meej tias seb puas muaj qhov txwv loj ntawm lub cev qhov chaw yuav tsum tau nruab - yog qhov chaw muaj qhov dav, luv thiab dav, siab thiab nyias, thiab lwm yam.
