Slocable MC4 ​​Solar Connectors rau Harsh Ib puag ncig

Ntawm qhov kub thiab txias tshaj 70 ° C los yog qhov siab tshaj 2000 meters, cov kev ua haujlwm ntawm cov khoom siv hluav taws xob sib txawv nyob ntawm qhov kev nyab xeeb.Ib puag ncig hnyav xws li suab puam lossis roob tuaj yeem muab cov xwm txheej zoo tshaj plaws irradiation thiab chaw rau cov tshuab photovoltaic siab.Slocable MC4 hnub ci connectorportfolio yog pov thawj rau cov ntawv thov no.

Thoob plaws ntiaj teb, photovoltaics kuj tau siv ntau ntxiv hauv cov chaw nyuaj.Kwv yees li 35% ntawm lub ntiaj teb thaj av yog suab puam, thiab tib neeg tab tom pib xav txog yuav ua li cas thiaj li siv tau ntau dua ntawm cov cheeb tsam no, uas txwv tsis pub muaj kev lag luam muaj peev xwm thiab thaj chaw muaj neeg nyob tsawg, xws li kev tsim hluav taws xob photovoltaic hauv cov suab puam kub thiab qhuav xws li. Raws li South America, Africa, Southern Europe thiab Middle East.

Tsis tas li ntawd, qhov siab siab kuj yog qhov chaw zoo tshaj plaws rau kev tsim hluav taws xob hnub ci.Vim qhov siab siab dua, cov chaw tsim hluav taws xob photovoltaic tuaj yeem tsim hluav taws xob li 50% ntau dua li hauv thaj chaw tiaj.Tsis tshua muaj siab ntawm hnub ci hluav taws xob thiab huab cua hnub ci tsis tu ncua muab kev pom zoo rau kev tsim hluav taws xob siab.Ntxiv nrog rau thaj tsam alpine ntawm Tebchaws Europe, hauv Andes ntawm South America, ntau thiab ntau cov chaw tsim hluav taws xob photovoltaic tau tsim los saum toj 2000 m saum hiav txwv.

Cov qauv kev nyab xeeb rau qhov kub thiab txias ib puag ncig

Muab qhov kev loj hlob sai ntawm cov kev lag luam no, IEC TC82 technical committee tau sib txawv hauv kev nthuav dav cov kev xav tau ntawm qhov sib txawv ntawm qhov kub thiab txias thiab teeb tsa los tsim cov tshiab PV modules rau cov ntawv thov scenarios nrog kev khiav hauj lwm kub txog li 70 ° C (98 feem pua) Kev nyab xeeb tus qauv IEC 61730 -1.Rau cov ntawv thov kub ib puag ncig xws li hauv thaj chaw suab puam, cov kev cai ntawm IEC TS 63126 yuav siv tau.

IEC TS 63126 qhia cov kev cai thermal rau photovoltaic modules thiab lawv cov khoom, xws li photovoltaic hlws ris thawv thiab photovoltaic connectors, nrog rau ob theem sib txawv.Ob pawg rau PV modules yog:

Chav Kawm Kub 1: sib npaug lossis siab dua 80 ° C (T98th)

Chav Kawm Kub 2: sib npaug lossis siab dua 90 ° C (T98th).

Yam tsawg kawg nkaus uas yuav tsum tau muaj rau sab sauv txwv kub (ULT) ntawm photovoltaic connectors yog raws li nram no:

ULT rau connectors siv rau PV modules ntawm chav kawm 1: 95 ° C yam tsawg kawg nkaus

ULT rau connectors siv rau chav kawm 2 PV modules: 105 ° C yam tsawg kawg nkaus

Yuav tsum muaj kev nyab xeeb rau qhov siab siab

Kev sib koom ua ke ntawm rwb thaiv tsev nyob rau hauv cov qauv kev nyab xeeb ntawm cov khoom siv hluav taws xob feem ntau yog tsim los rau cov ntawv thov txog li 2000 meters saum toj no hiav txwv theem.Rau cov ntawv thov siab dua, kev tshem tawm yuav tsum tau kho dua vim tias cov cua qis qis txo qhov tsis kam ntawm cov khoom siv hluav taws xob kom tshem tawm qhov hluav taws xob flashover tshwm sim.Yog li, qhov kev tshem tawm yam tsawg kawg nkaus yuav tsum tau muab sib npaug los ntawm kev kho qhov tseem ceeb hauv IEC 60664-1: 2020 lub rooj, lossis txheeb xyuas los ntawm qhov ntsuas qhov ntsuas hluav taws xob siab dua.

Tau ntau tshaj kaum xyoo, Slocable PV DC kev sib txuas system tau paub txog nws txoj kev ntseeg siab thiab ruaj khov.Tam sim no, kuaj thiab txheeb xyuas los ntawm TÜV Rheinland, Slocable MC4 connector yog ib qho ntawm cov khoom siv hluav taws xob photovoltaic kom tau raws li qhov yuav tsum tau ua hauv PV systems siv module kub chav kawm 2. Qhov no txhais tau hais tias Slocable PV connector tau sim thiab ua pov thawj tias yuav siv tau. nyob rau hauv huab cua mus txog 105 ° C.
