Cov chav da dej yog dab tsi?

Muaj peb thaj chaw nyob hauv chav dej. Txhua cheeb tsam cov kev cai zonal feem ntau yog raws li qhov yuav ua rau cov dej tuaj yeem sib cuag lossis ze rau cov khoom siv hluav taws xob. Lub installation yuav raug mob, tab sis qhov kev pheej hmoo ntawm hluav taws xob poob siab yog qhov tseem ceeb dua. Nov yog peb chav dej:

Zone 0
IP68 yog qhov xav tau yam tsawg kawg nkaus rau cheeb tsam no. Qhov chaw hauv lub dab da dej los yog da dej yog qhov no. Nws tsuas yog siv tau 12V SELV (Kev Nyab Xeeb Ntxiv Tsawg Voltage)

khoom siv.

Zone 1 xav tau qhov ntsuas IP44 tsawg kawg. Qhov no yog qhov chaw mus txog 2.25 meters siab uas yog ncaj qha saum lub da dej thiab hauv chav da dej.

Zone 2
zoo ib yam li saum toj no, xav tau yam tsawg kawg nkaus IP44. Qhov no yog qhov chaw uas tsis nyob hauv chav dej lossis chav da dej.

Cov cheeb tsam sab nraud ntawm cov no (yav tas los hu ua zone 3) yog raws li cov txheej txheem kev cai thiab tsis tas yuav tsum muaj qhov ntsuas IP. Txhawm rau kom ntseeg tau tias lawv txhua tus sib tw, peb qhia kev txhim kho chav dej teeb rau IP44 lossis siab dua qhov tsawg kawg nkaus. Lawv yuav tiv taus ntau dua rau chav thiab nws txhim kho qhov pom ntawm qhov chaw. Yog tias cov LEDs kim heev tau siv, chav yuav ua rau lub teeb tsis ua haujlwm, uas tuaj yeem raug nqi. Lub teeb pom kev zoo nrog qhov ntsuas IP yuav raug nqi ntxiv £ 2, thaum hloov lub LED yuav raug nqi £ 4. Koj tsis tas yuav muaj kev xaiv vim tias IP65 kev ntsuam xyuas yog ib qho qauv rau feem ntau ntawm cov teeb pom kev zoo LED. Nruab IP65 thoob plaws hauv koj chav dej yog tias koj tsis paub meej.

30ma RCD (Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob) yuav tsum tau siv los tiv thaiv txhua qhov hluav taws xob hauv chav dej. Txawm hais tias qhov no yog tam sim no tus txheej txheem txheej txheem thiab raug yuam los ntawm Tshooj P ntawm Txoj Cai Tswj Tsev, txawm li cas los xij, nws tseem ceeb heev kom paub tseeb ob npaug, tshwj xeeb tshaj yog hauv cov qauv qub.

Cov chav da dej tuaj yeem nkag siab zoo tshaj plaws thaum koj paub txog kev ntsuas IP. Txawm hais tias IP sawv cev rau kev tiv thaiv thoob ntiaj teb, lo lus "ingress tiv thaiv" yog siv ntau zaus. Thaum X tau siv, nws qhia tau tias kev tiv thaiv cov khoom tsis tseem ceeb.

IP Ratings - Phau Ntawv Qhia

Ib qho kev kaw lossis cov khoom siv hluav taws xob theem ntawm kev tiv thaiv ingress yog qhia los ntawm qhov ntsuas IP, uas yog tus lej. Cov kev ntsuam xyuas tshwj xeeb uas ua los ntawm cov khoom tsim los yog hauv qhov chaw kuaj pom muaj pov thawj txiav txim siab cov kev ntsuas no.

Ob tus lej ua tus IP tus lej, thawj qhov qhia txog qib ntawm kev tiv thaiv cov khib nyiab zoo li plua plav thiab qhov thib ob tiv thaiv cov kua dej zoo li dej. Kev tiv thaiv qib yuav zoo dua tus lej ntau dua. Cov thawj uas tau nthuav tawm ntawm nplooj ntawv no yog raws li hauv qab no:

Touchproof IP20
Tus naj npawb 2 qhia txog kev tiv thaiv cov khib nyiab txog li 12 mm square. raws li tus ntiv tes ntawm tus neeg.

Lub zero qhia txog qhov tsis muaj dej tsis kam.

Txwv dej tsis kam, IP44
Thawj plaub sawv cev tiv thaiv cov khib nyiab txog li 1 hli square.

Kev tiv thaiv los ntawm cov dej txau nyob rau hauv tag nrho cov lus qhia yog sawv cev los ntawm plaub thib ob. xws li dej txaws-resistant.

Dej-resistant IP65
Tus naj npawb rau sawv cev rau kev tiv thaiv plua plav tag.

Tus naj npawb 5 qhia txog kev tiv thaiv cov dav hlau dej nrog lub siab me me. xws li lub tshuab ntxhua khaub ncaws.

Submersible, IP67
muaj peev xwm submerge nyob rau hauv dej ib ntus. ntawm 150mm thiab 1 meter hauv qhov tob.

Submersible, IP68
Nws tuaj yeem txuas ntxiv submerged hauv dej. Nws yuav raug kaw tag.
