Luam tawm los ntawm TIG Transformer|Technical Standards & Ua raws cai
Taw qhia
Thaum xaiv cov khoom siv hluav taws xob faib rau cov haujlwm thoob ntiaj teb, kev nkag siab txog Ingress Protection (IP) ntsuas qhov system yog qhov tseem ceeb. Raws li tau hais los ntawm IEC 60529 (thiab cov qauv sib npaug xws li GB / T 4208), IP code muab ib txoj hauv kev lees paub thoob ntiaj teb rau kev faib cov qib kev tiv thaiv los ntawm cov khoom siv hluav taws xob tiv thaiv cov khoom, plua plav, thiab dej.
Ntawm TIG Transformer, tag nrho peblub zog faib lub thawv thiabtransformercov ntaub thaiv npogtau tsim thiab txheeb xyuas kom tau raws li cov qauv thoob ntiaj teb no. Phau ntawv qhia no piav qhia txog qhov kev ntsuam xyuas IP hauv cov ntsiab lus siv tau los pab koj txiav txim siab txog kev paub.
Tus IP Code Structure
Tus IP code muaj cov tsiaj ntawv "IP" ua raws li ob tus yam ntxwv tus lej:
- Thawj Zaug (0–6): Kev tiv thaiv cov khoom txawv teb chaws thiab nkag mus rau qhov chaw muaj kev phom sij.
- Tus lej thib ob (0–9): Kev tiv thaiv kev nkag mus ntawm cov dej uas muaj kev phom sij.
Piv txwv li, qhov ntsuas ntawm IP66 qhia tias:
- 6 (Thawj Tus lej): Plua plav- nruj - tsis muaj plua plav tawm.
- 6 (Tus lej thib ob): Tiv thaiv cov dav hlau dej muaj zog.
>Nco tseg: Tag nrho TIG Transformer enclosures yog thib peb - tog tau sim kom siv tau cov lus tshaj tawm IP.

Kev Xeem & Kev Tshawb Fawb
Ntawm TIG Transformer, peb ua raws li cov txheej txheem xeem uas tau teev tseg los ntawm IEC 60529 kom siv tau qhov kev ua tau zoo ntawm cov ntaub ntawv:
- Plua plav Test (IP5X / IP6X): Cov ntaub thaiv npog tau muab tso rau hauv cov plua plav chamber nrog talc hmoov rau 8 teev. Rau IP6X, lub tshuab nqus tsev yog siv los tsim qhov tsis zoo siab (20 mbar) thaum kuaj.
- Kev Ntsuas Dej (IPX1–IPX6): Ua los ntawm kev siv lub thawv calibrated drips, oscillating spray tubes, lossis dej dav hlau nozzles raws li tau hais hauv tus qauv.
- Immersion Test (IPX7 / IPX8): Cov ntaub thaiv npog yog submerged ntawm qhov tob thiab ntev (piv txwv li, 1 m rau 30 feeb rau IPX7).
- Seal Aging Test: Gaskets thiab sealing cov ntaub ntawv yog raug rau kom ceev aging kom paub tseeb tias ntev - lub sij hawm ua hauj lwm.
Txhua qhov kev ntsuam xyuas yog ua los ntawm ISO/IEC 17025 qhov chaw kuaj pom zoo (CNAS), thiab peb cov khoom tsim khoom tau raug coj mus kuaj ua ntu zus rov- pov thawj kom ntseeg tau tias ua raws li qhov txuas mus ntxiv.

Common Misconceptions & Technical Notes
1. IPX7 thiab IPX8 tsis tau txais kev tiv thaiv IPX5 lossis IPX6.
Cov kev sim rau kev tso dej (IPX7/8) txawv ntawm cov dav hlau dej (IPX5/6). Ib qho chaw nyob IP67 tsis tas yuav tiv thaiv cov dav hlau dej muaj zog tshwj tsis yog tshwj xeeb dual- ntsuas (xws li IP66 / IP67).
2. IP ntsuam xyuas tsis suav nrog corrosion kuj.
Rau ib puag ncig marine lossis tshuaj lom neeg, xaiv cov ntaub ntawv uas tsim nyog (piv txwv li, stainless hlau 316L, hmoov-coated aluminium, lossis fiberglass- reinforced polyester).
3. Kev ntsuas IP siab dua tuaj yeem cuam tshuam rau kev tswj xyuas thermal.
Cov ntaub thaiv npog (IP65 thiab saum toj no) yuav tsum tau ua tib zoo tsim thermal los yog ua kom txias thaum lub tsev sov- tsim cov khoom xws li transformers lossis cov khoom siv fais fab.
4. Mechanical impact resistance yog them los ntawm IK code, tsis yog tus IP code.
Rau qhov chaw uas muaj kev pheej hmoo ntawm kev cuam tshuam rau kev siv tshuab, qhia qhov ntsuas IK (piv txwv li, IK08, IK10) ntxiv rau qhov ntsuas IP.

Cov lus nug nquag nug (FAQ)
1. Puas yog qhov ntsuas IP siab dua ib txwm zoo dua?
Tsis tas li. Kev ntsuas IP siab dua txo qhov cua, nce qhov hnyav thiab tus nqi, thiab feem ntau xav tau cov cuab yeej qhib. Tshaj -kev qhia tshwj xeeb tuaj yeem ua rau muaj cua sov dhau los lossis kev saib xyuas nyuaj. Peb pom zoo kom xaiv qhov tsawg kawg nkaus uas yuav tsum tau ntsuas IP raws li koj qhov chaw nyob.
2. Ib lub qhov rooj puas tuaj yeem ntsuas IP66 thiab IP67?
Yog lawm. IP66 tiv thaiv cov dav hlau dej muaj zog, thaum IP67 npog kev nkag mus rau ib ntus (1m rau 30 feeb). Ntau TIG Transformer sab nraum zoov cov ntaub ntawv yog dual- ntsuas IP66 / IP67 los daws ob qho tib si dej nyab thiab luv - lub sijhawm dej nyab.
3. Puas yog IP ntsuas kev tiv thaiv corrosion?
Tsis yog. IP ntsuam xyuas tsuas yog npog cov plua plav thiab dej nkag. Corrosion kuj nyob ntawm cov ntaub ntawv enclosure. Rau ib puag ncig ntawm ntug dej hiav txwv lossis tshuaj lom neeg, peb pom zoo kom tsis muaj steel hlau (316L) lossis fiberglass- siv zog polyester.
4. Qhov ntsuas IP twg kuv xav tau rau kev siv sab nraum zoov?
IP65 yam tsawg kawg nkaus, IP66 pom zoo. Rau thaj chaw uas muaj nag los nag lossis dej nyab, xaiv IP67 lossis IP68. Kuj tseem qhia txog UV- cov ntaub ntawv tiv taus thiab cov pa nqus dej kom tiv thaiv kev ua paug sab hauv.
5. Kuv puas tuaj yeem hloov kho tus IP- ntsuas qhov chaw nyob hauv thaj teb?
Tsis yog tsis muaj kev pheej hmoo rau qhov ntsuas. Txhua qhov drilling lossis ntxiv nkag yuav tsum siv cov qog uas tau lees paub thiab kev sib khi kom raug. TIG Transformer muaj ua ntej- teeb tsa kev sib tw thiab cov khoom siv sib khi kom tswj tau tus IP kev ncaj ncees tom qab kev hloov kho.
6. Kuv yuav ua li cas txheeb xyuas qhov ntsuas IP uas tau thov?
Thov daim ntawv tshaj tawm kev xeem los ntawm ISO/IEC 17025 kev lees paub (CNAS lossis sib npaug) kuaj. Daim ntawv tshaj tawm yuav tsum tau hais txog qhov ntsuas IP, cov txheej txheem xeem raws li IEC 60529, thiab kev txheeb xyuas tus qauv. TIG Transformer muab cov ntaub ntawv thib peb - tog raws li kev thov.
7. Kuv puas tuaj yeem siv IP65 enclosure hauv thaj chaw muaj kev phom sij (explosive)?
Tsis muaj IP65 ib leeg tsis txaus. Explosive atmospheres xav tau Ex-cov ntaub ntawv pov thawj (xws li ATEX, IECEx). Txawm li cas los xij, feem ntau Ex enclosures kuj muaj qhov ntsuas IP - feem ntau IP66 lossis siab dua. TIG Transformer muaj kev sib xyaw ua ke Ex thiab IP tau lees paub daws teeb meem.
