Yintoni ekufuneka ithathelwe ingqalelo phambi kokuThenga iPV DC yokuqhawula iSwitch?

Kufakelo lwePV, iIswitshi yokuqhawula i-DCifana ne-airbag emotweni.Umgangatho we-IEC 60364-7-712 ufuna ukusetyenziswa kwe-PV DC yokuqhawula utshintsho phakathi kwe-PV kunye ne-inverter.I-Slocable DC disconnect switches yenzelwe ngokukodwa ukukhupha ii-inverters ze-DC/AC ukusuka kuluhlu lwephaneli yelanga.Sinikezela ngePV yokuqhawula iiswitshi zombane ukuya kuthi ga kwi-1500 V DC.Zingasetyenziselwa ukudala amanqaku okutshintsha okuzimeleyo njengoko kufunwa yi-VDE 6012, umzekelo, ukuvumela ukuqhawulwa okukhuselekileyo kwee-inverters eziphosakeleyo.Yonke i-DC switch switch disconnector switches kwiipali ezimbini kwaye ifanelekile kwiinkqubo ezivunjululweyo.

Indlu ye-PV yokuqhawula i-switch switch ilungele ukufakwa kwaye ibonelela ngokusebenza ngokusebenza kwe-30 A kwi-1000 V / 1500 V DC.Ifumaneka kwimitya emibini kunye nene kunye neentlobo ezimbini zekhonkco eziqhelekileyo zoqhagamshelwano.I-MC4 okanye i-metric cable glands ivumela ukuhlanganiswa okugudileyo kwiingcamango zenkqubo ezahlukeneyo.I-DC yokuqhawula i-switch enclosure ineklasi yokukhusela i-IP66 kwaye ngoko ifanelekele ukufakela ngaphandle.Umsebenzi wokutshixa ubonelela ngokhuseleko ngexesha lenkonzo kunye nokugcinwa.Into yembuyekezo yoxinzelelo ithintela ukunyuswa ekuqokeleleni kwaye ngaloo ndlela ithintela ukusilela ngenxa yombane.

Yintoni ekufuneka ithathelwe ingqalelo phambi koThenga iPV yokuqhawula iSwitch?

1. Loluphi uhlobo olufunayo?

Kufuneka uqwalasele uhlobo lwe-PV yokuqhawula uqhagamshelwano olufunekayo, umzekelo ukuqonda iimfuno zakho zamandla.I-Slocable inezitshixo zokuqhawula ukusuka kwi-DC 1000V ukuya kwi-1500V.Ukuba ufuna isisombululo esenziwe ngokwezifiso, sinokubonelela ngeeswitshi zokuqhawula i-PV ze-600V, i-800V, i-1000V, i-1200V okanye i-1500V.

2. I-Voltage kunye neyangoku

Ukuba ufuna ukufaka i-DC yokuqhawula uqhagamshelwano, kufuneka ulinganise abafowunelwa bayo ukuze uqinisekise ukuba inokwamkela amandla ahanjiswa ngegridi yayo.

Ukuba ufuna imisinga ephezulu, kuya kufuneka uqhagamshelwe ngakumbi ukuze uxhase ukunqanda ukushisa okugqithisileyo kwesixokelelwano sombane.I-Slocable PV yethu yokuqhawula i-switch switch isuka kwi-1000V, i-1200V ukuya kwi-1500 kwaye ihlelwe kwi-32A kunye ne-55A.

3. Izatifikethi ze-IEC kunye ne-AS

Enye into ekufuneka uyiqwalasele kukwazi izatifikethi ze-IEC kunye ne-AS.Ukuba umvelisi wokutshintsha uqhagamshelo lweDC unezi zatifikethi, oko kuthetha ukuba inkampani ilandela izikhokelo zamazwe ngamazwe xa kusenziwa i-PV DC yokuqhawula iimveliso zokutshintsha.

Ngokomzekelo, kwinxalenye yokuqala ye-EIC 60204-1: 2016, umenzi kufuneka abonelele ngokusetyenziswa ngesandla ukucima ukutshintshela kumthombo wamandla oyintloko ofakwe kunye neeparitha zoyilo oluthile.

4. Indlela yokufakela

Kuya kufuneka kwakhona uqwalasele indawo ekhethwayo yokunyusela iswitshi yoqhawulo lwe-DC kunye nesimbo sokunyusa esifanelekileyo kwisicelo sakho.Isitayela esixhaphakileyo yintaba yemingxuma emine, eyakhiwe kwipatheni yesikwele kunye nemingxuma emine ye-screw kwikona nganye.Esi simbo sifanelekile ukuba ujonge ukunyusa iswitshi kwindawo ethe tyaba, njengoko ivumela iswitshi ukuba igungxulwe ngokusemandleni.

Iimpawu zeSlocable PV DC disconnect switch:

1. Uqhagamshelwano lomphetho weemela oluthembekileyo kakhulu kunye negumbi lokupholisa i-arc elide liqinisekisa ukwahlukaniswa okukhuselekileyo kombane weDC.
2. Yandisa ukhuseleko ngenqaku le-Slocable elinelungelo elilodwa lomenzi “Isitshixo soKhuseleko”.
3. I-Slocable PV yokuqhawula i-switch series ifumaneka kwi-2 ukuya kwi-8 iinguqulelo zepali kunye neentlobo ezahlukeneyo zokunyuka kunye nokusingatha ulungelelwaniso oluninzi lwe-OEM okanye ukufakwa kwezicelo zentsimi.

Ezi zitshintshi ze-PV ziye zavavanywa ngabahloli kwaye ziyi-UL508i, i-TUV (60947-1 & 60947-3), i-CE kunye ne-CCC eqinisekisiwe.

I-Slocable ikwabonelela nezinye izincedisi ze-PV zelanga, kubandakanya iziqhagamshelo zeSolar MC4, izibambi ze-fuse ze-MC4, iibhokisi ze-photovoltaic junction kunye nabakhuseli botyando be-DC.
