Qhov mob taw tes ntawm photovoltaic mc4 connector installation: Crimping

Nrog rau kev loj hlob sai ntawm kev faib tawm, tshwj xeeb tshaj yog tsev neeg photovoltaic kev ua lag luam nyob rau hauv xyoo tas los no, cov teeb meem zoo ntawm photovoltaic systems tau dhau los ua qhov tseem ceeb.Hluav taws kub hauv lub tshuab hluav taws xob photovoltaic yuav tsis tsuas ua rau muaj kev nyab xeeb ntawm tus kheej, tab sis kuj muaj kev cuam tshuam tsis zoo rau kev lag luam.Raws li cov ntaub ntawv tshawb fawb txawv teb chaws, cov khoom sib txuas sib txuas sib txuas thiab cov khoom sib txuas tsis tu ncua yog qhov ua rau thawj thiab thib peb ua rau hluav taws.Cov kab lus no tsom mus rau kev tsom xam ntawm qhov tsis sib xws ntawm kev teeb tsa ntawm cov khoom sib txuas, tshwj xeeb tshaj yog crimping ntawm photovoltaic cable thiab connector hlau core, thiaj li yuav muab cov neeg siv nrog qee qhov kev siv, tuav lub photovoltaic system, thiab tiv thaiv cov txiaj ntsig ntawm cov neeg siv.

Kev ua lag luam

Nyob rau hauv lub tshuab hluav taws xob photovoltaic, cov khoom siv hluav taws xob photovoltaic feem ntau yog siv rau hauv cov khoom sib txuas, cov thawv sib txuas, cov khoom siv hluav taws xob thiab cov kev sib txuas ntawm lawv, feem ntau yog ntsia hauv lub Hoobkas, thiab cov crimp zoo kuj tseem txhim khu kev qha.Kwv yees li ntawm 10% ntawm cov txuas txuas ntxiv yuav tsum tau muab ntsia rau ntawm qhov project site, feem ntau yog hais txog qhov yuav tsum tau nruab cov khoom sib txuas ntawm ob qho kawg ntawm photovoltaic cable txuas txhua lub cuab yeej.Raws li cov kev paub dhau los ntawm ntau xyoo ntawm cov neeg tuaj xyuas, vim tsis muaj kev cob qhia ntawm cov neeg ua haujlwm hauv qhov chaw thiab kev siv cov cuab yeej crimping, crimping irregularities muaj ntau, raws li qhia hauv qab no.

Hom thiab yam ntxwv ntawm cov hlau cores

Cov tub ntxhais hlau yog lub cev tseem ceeb ntawm cov khoom sib txuas thiab txoj hauv kev tseem ceeb tshaj plaws.Tam sim no, feem ntau ntawm photovoltaic connectors nyob rau hauv kev ua lag luam siv ib tug "U"-zoo li tus hlau core, uas yog stamped thiab tsim los ntawm ib daim ntawv tooj liab, tseem hu ua stamped hlau core.Ua tsaug rau cov txheej txheem stamping, "U"-zoo li tus hlau tub ntxhais tsis tsuas yog muaj kev ua haujlwm siab, tab sis kuj tuaj yeem npaj rau hauv cov saw hlau, uas yog qhov tsim nyog rau kev siv cov hlua khi hlua khi.

Qee cov khoom siv hluav taws xob photovoltaic siv lub "O" zoo li tus hlau core, uas yog tsim los ntawm qhov drilling qhov ntawm ob qho kawg ntawm ib tug nyias tooj liab pas nrig, uas tseem hu ua machined hlau core.Cov tub ntxhais "O"-zoo li tus hlau tuaj yeem tsuas yog crimped ib tus zuj zus, uas tsis haum rau siv hauv cov khoom siv tshuab.

【Daim duab 2: Hlau core hom】

Kuj tseem muaj cov tub ntxhais hlau uas tsis tshua muaj hlau uas tsis muaj crimp, uas txuas nrog lub cable los ntawm daim ntawv caij nplooj ntoos hlav.Txij li tsis muaj cov cuab yeej crimping yuav tsum tau, installation yog kuj yooj yim thiab yooj yim.Txawm li cas los xij, kev sib txuas ntawm lub caij nplooj ntoo hlav yuav ua rau muaj kev sib cuag loj, thiab kev ntseeg siab ntev tsis tuaj yeem lav.Qee lub koom haum muab ntawv pov thawj kuj tsis pom zoo rau cov tub ntxhais hlau zoo li no.

Kev paub yooj yim ntawm crimping

Crimping yog ib qho ntawm cov txheej txheem yooj yim tshaj plaws thiab kev sib txuas.Suav crimping tshwm sim txhua hnub.Nyob rau tib lub sijhawm, crimping tau raug pov thawj los ntawm kev paub tab thiab txhim khu kev qha kev sib txuas tshuab.

Crimping txheej txheem

Kev ntseeg siab ntawm crimping feem ntau nyob ntawm cov cuab yeej thiab kev ua haujlwm, ob qho tib si txiav txim siab seb qhov kawg crimping cuam tshuam raws li qhov yuav tsum tau ua ntawm tus qauv.Siv lub "U"-zoo li tus hlau core ua piv txwv.Nws yog ib qho khoom siv tooj liab tin-plated thiab yuav tsum tau txuas nrog photovoltaic cable los ntawm crimping.Cov txheej txheem crimping yog raws li nram no:

【Daim duab 3: Cov txheej txheem crimping】

Nws tsis yog qhov nyuaj kom pom tias "U" zoo li cov hlau tseem ceeb crimping yog txheej txheem uas thaum lub siab crimping maj mam txo qis (thaum lub crimping quab yuam maj mam nce), daim ntawv tooj liab qhwv nrog lub cable tooj liab hlau yog maj mam compressed.Hauv cov txheej txheem no, kev tswj ntawm crimping qhov siab ncaj qha txiav txim siab qhov zoo ntawm crimping.Kev tswj ntawm crimp dav tsis yog ib qho tseem ceeb heev, vim hais tias lub crimp tuag txiav txim siab qhov dav tus nqi.

Crimp qhov siab

Ntau tus neeg paub tias crimping xoob dhau los yog nruj dhau tsis zoo, yog li thaum lub crimping nce, yuav tsum tswj qhov siab crimping ntau npaum li cas?Tsis tas li ntawd, ob qho kev ntsuas tseem ceeb, uas yog lub zog rub tawm thiab hluav taws xob conductivity, hloov pauv li cas thaum tus txheej txheem no?

[Daim duab 4: Pull-off quab yuam thiab crimp qhov siab]

Raws li qhov siab crimping maj mam txo qis, lub zog rub tawm ntawm lub cable thiab cov tub ntxhais hlau yuav maj mam nce mus txog thaum nws mus txog qhov "X" point hauv daim duab saum toj no.Yog tias qhov siab crimping tseem txo qis, lub zog rub tawm yuav txo qis vim qhov kev puas tsuaj zuj zus ntawm cov qauv ntawm cov hlau tooj liab.

[Daim duab 5: Conductivity thiab crimp qhov siab]

Daim duab saum toj no piav qhia txog cov yam ntxwv hluav taws xob mus sij hawm ntev ntawm crimping.Qhov loj dua tus nqi, qhov zoo dua ntawm cov hluav taws xob conductivity, thiab qhov zoo ntawm cov khoom siv hluav taws xob ntawm cov cable thiab hlau core txuas."X" sawv cev rau qhov zoo tshaj plaws.

Yog hais tias ob lub nkhaus saum toj no yog superimposed ua ke, peb tuaj yeem tau txais cov lus xaus yooj yim:

        Covzoo tshaj plaws crimping qhov siab tsuas yog ib qho kev xav txog ntawm kev rub tawm quab yuam thiab conductivity, thiab tus nqi ntawm thaj tsam ntawm ob lub ntsiab lus zoo tshaj plaws, raws li qhia hauv qab no.

Crimping kev ntsuam xyuas zoo

Cov kev txiav txim siab feem ntau siv hauv kev lag luam yog raws li hauv qab no:

■ Lub crimping qhov siab / dav tuaj yeem ntsuas nrog vernier caliper nyob rau hauv qhov kev txiav txim siab;

■ Pull-off quab yuam, uas yog, lub zog yuav tsum tau rub los yog tawg cov tooj liab hlau los ntawm qhov chaw crimping, xws li 4mm2 cable, IEC 60352-2 yuav tsum muaj tsawg kawg yog 310N;

■ Resistance, noj 4mm2 cable raws li piv txwv, IEC 60352-2 yuav tsum tau cov kuj ntawm crimp kom tsawg tshaj li 135 microohms;

■Kev soj ntsuam hla ntu, tsis muaj kev puas tsuaj ntawm cheeb tsam crimping, tsom xam qhov dav, qhov siab, compression tus nqi, symmetry, tawg thiab burrs, thiab lwm yam.

Yog tias nws yuav tso tawm cov cuab yeej tshiab lossis tshiab crimping tuag, ntxiv rau cov ntsiab lus saum toj no, nws tseem yuav tsum tau saib xyuas qhov kev tiv thaiv kev ruaj ntseg nyob rau hauv qhov kub thiab txias, xa mus rau tus qauv IEC 60352-2.

Crimping cuab tam

Feem ntau ntawm photovoltaic connectors yog ntsia nyob rau hauv lub Hoobkas los ntawm automated khoom, thiab crimp zoo yog siab.Txawm li cas los xij, rau cov khoom sib txuas uas yuav tsum tau teeb tsa ntawm qhov project site, crimping tsuas yog ua tau nrog crimping pliers.Tus thawj kws crimping pliers yuav tsum tau siv rau crimping.Ib qho yooj yim vise lossis koob-qhov ntswg pliers tsis tuaj yeem siv rau crimping.Ntawm qhov tod tes, qhov zoo ntawm crimping yog tsawg, thiab qhov no kuj yog ib txoj kev uas tsis tau lees paub los ntawm connector manufacturers thiab cov koom haum muab ntawv pov thawj.

Irregular crimping txaus ntshai

Cov crimping tsis zoo tuaj yeem ua rau tsis ua raws li cov lus qhia tshwj xeeb, kev tiv thaiv tsis ruaj khov, thiab sealing tsis ua haujlwm.Nws yog ib qho kev pheej hmoo loj uas cuam tshuam rau tag nrho cov haujlwm thiab cov txiaj ntsig ntawm photovoltaic fais fab nroj tsuag.

Cov ntsiab lus

■ Lub connector yog ib feem me me, tab sis nws yuav cuam tshuam rau kev ua haujlwm ntawm qhov project photovoltaic.Kev cuam tshuam nrog kev ua tau zoo feem ntau txhais tau tias muaj kev poob qis thiab kev pheej hmoo siab, uas tuaj yeem zam tau;

■ Rau kev teeb tsa ntawm photovoltaic connectors, qhov txuas crimping yog qhov tseem ceeb tshaj plaws, thiab nws raug nquahu kom siv cov cuab yeej crimping kws tshaj lij.Rau engineering installers, crimping kev cob qhia yog ib qho tseem ceeb txuas.
