IP tiv thaiv ntsuas ntawm lub hwj chim mov
Kev tiv thaiv qib qhia txog qib uas cov khoom siv hluav taws xob tiv thaiv kev nkag mus ntawm cov khoom txawv teb chaws thiab ya raws. Hauv tsab xov xwm no, koj yuav kawm paub tias qib kev tiv thaiv IP muaj nyob li cas, lawv txawv li cas ntawm ib leeg, thiab dab tsi yuav tsum tau them rau thaum xaiv lub hwj chim.
Ib puag ncig cuam tshuam xws li plua plav lossis dej noo tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob. Tsis tas li ntawd, nws yuav tsim nyog los tiv thaiv cov khoom siv sab hauv los ntawm kev nkag mus ntawm cov khoom txawv teb chaws xws li cov cuab yeej, cov ntsia hlau, lossis cov xov hlau, lossis tiv thaiv cov neeg siv kev sib cuag. Tshwj xeeb tshaj yog thaum siv cov khoom siv hluav taws xob sab nraud ntawm cov khoom hluav taws xob, qib kev tiv thaiv, hu ua IP code (International Protection code), yuav tsum tau txiav txim siab thaum xaiv. Tsuas yog thaum qhov kev tiv thaiv qib sib npaug ntawm ib puag ncig cov xwm txheej tuaj yeem siv cov khoom siv hluav taws xob kom nyab xeeb, tsis txhob raug nqi ntau.
IP tiv thaiv qib yog dab tsi?
Cov qib kev tiv thaiv feem ntau txhais los ntawm tus lej IP ("International Protection"; feem ntau hu ua "Ingress Protection" hauv lus Askiv) ua raws li ob tus lej (xws li IP20, IP54, IP67, thiab lwm yam).
Thawj tus lej qhia txog qib ntawm kev tiv thaiv kev sib cuag thiab kev nkag mus ntawm cov khoom txawv teb chaws, xuab zeb, thiab hmoov av. Tus lej thib ob qhia txog qib kev tiv thaiv dej thiab noo noo.
Rau cov khoom siv fais fab, kev tiv thaiv qib yog txiav txim siab raws li DIN EN 60529 tus qauv. Rau txoj kev tsheb, ISO 20653: 2013 tus qauv kuj tseem siv tau. Txawm li cas los xij, tus qauv no tsuas yog siv rau cov khoom siv hluav taws xob hauv tsheb uas yuav tsum tau muaj kev tiv thaiv ntxiv tiv thaiv siab -kev tu siab (xws li, siv lub dav hlau dav hlau).
Hauv cov ntsiab lus ntawm cov khoom siv hluav taws xob, qib kev tiv thaiv qee zaum tsis meej pem nrog kev faib tawm rau kev tiv thaiv hluav taws xob. Kev tiv thaiv qib yog hais txog kev tiv thaiv cov khoom txawv teb chaws, dej nkag, thiab kev sib cuag, qhov kev faib IEC rau kev tiv thaiv hluav taws xob qhia txog kev tsim kho thiab rwb thaiv tsev ntawm cov khoom siv hluav taws xob los tiv thaiv cov neeg siv hluav taws xob.
Cov lus hauv qab no qhia txog lub ntsiab lus ntawm tus lej hauv qib tiv thaiv IP:
Kev tiv thaiv tawm tsam txawv teb chaws (thawj tus lej)
| Tus lej | Txhais |
|---|---|
| 0 | Tsis muaj kev tiv thaiv |
| 1 | Tiv thaiv cov khoom uas muaj txoj kab uas hla Ntau dua lossis sib npaug li 50 mm (xws li tes) |
| 2 | Tiv thaiv cov khoom uas muaj txoj kab uas hla Ntau dua lossis sib npaug li 12 hli (piv txwv li, ntiv tes) |
| 3 | Tiv thaiv cov khoom uas muaj txoj kab uas hla Ntau dua lossis sib npaug li 2.5 hli (xws li cov cuab yeej) |
| 4 | Tiv thaiv cov khoom uas muaj txoj kab uas hla Ntau dua lossis sib npaug li 1 hli (xws li cov xov hlau) |
| 5 | Tag nrho tiv thaiv kev sib cuag thiab plua plav |
| 6 | Kev tiv thaiv tag nrho tiv thaiv kev sib cuag thiab plua plav tag- nruj |
Kev Tiv Thaiv Kev Tiv Thaiv Dej (Tus lej thib ob)
| Tus lej | Txhais |
|---|---|
| 0 | Tsis muaj kev tiv thaiv |
| 1 | Tiv thaiv cov vertically ntog dej |
| 2 | Tiv thaiv cov vertically ntog tee dej thaum lub qhov thaiv yog tilted mus txog 15 degree |
| 3 | Tiv thaiv cov tshuaj tsuag dej ntawm cov ces kaum mus txog 60℃los ntawm ntsug |
| 4 | Tiv thaiv tsis txhob txaws dej los ntawm txhua qhov kev taw qhia |
| 5 | Tiv thaiv cov dav hlau dej los ntawm txhua qhov kev taw qhia |
| 6 | Tiv thaiv cov dej dav hlau muaj zog los ntawm txhua qhov kev taw qhia |
| 7 | Tiv thaiv tiv thaiv ib ntus immersion |
| 8 | Tiv thaiv tsis tu ncua immersion |
| 9 | Tiv thaiv kom siab -siab thiab siab- cua kub dej dav hlau |
Dab tsi yog qhov kev tiv thaiv kev ntsuas rau cov khoom siv fais fab?
Qhov kev ntsuas kev tiv thaiv yuav tsum nyob ntawm qhov chaw teeb tsa thiab ib puag ncig ib puag ncig hauv daim ntawv thov sib xws. Cov neeg tsim khoom uas muab cov khoom siv hluav taws xob los ntawm cov khoom lag luam feem ntau tsuas yog muab cov khoom lag luam nrog cov kev xaiv IP tiv thaiv, uas tau dhau los ua cov qauv kev lag luam. Cov lus hauv qab no qhia txog kev tiv thaiv ntau tshaj plaws rau cov khoom siv fais fab.
| Kev tiv thaiv ntsuas | Cov khoom txawv teb chaws (digit) | Kev tiv thaiv tawm tsam txawv teb chaws | Dej (digit) | Kev tiv thaiv tiv thaiv dej |
|---|---|---|---|---|
| IP20 | 2 | Tiv thaiv cov khoom uas muaj txoj kab uas hla Ntau dua lossis sib npaug li 12 hli (piv txwv li, ntiv tes) | 0 | Tsis muaj kev tiv thaiv |
| IP54 | 5 | Tag nrho tiv thaiv kev sib cuag thiab plua plav | 4 | Tiv thaiv tsis txhob txaws dej los ntawm txhua qhov kev taw qhia |
| IP65 | 6 | Kev tiv thaiv tag nrho tiv thaiv kev sib cuag thiab plua plav tag- nruj | 5 | Tiv thaiv cov dav hlau dej los ntawm txhua qhov kev taw qhia |
| IP67 | 6 | Kev tiv thaiv tag nrho tiv thaiv kev sib cuag thiab plua plav tag- nruj | 7 | Tiv thaiv tiv thaiv ib ntus immersion |
