Ingaba iPV Array DC Isolator switch iyikhusela njani iPhotovoltaic System?

       PV uluhlu DC isolator iswitshi, njengoko igama libonisa, lutshintsho oluhlukanisa i-DC.Isetyenziswa kakhulu kwiinkqubo zesikhululo samandla e-photovoltaic, kwaye isetyenziswe phakathi kwe-high-voltage DC photovoltaic arrays kunye ne-grid-connected inverters ukunqumla i-arcs eyenziwe ngamandla e-DC, ukuphepha iingozi ezinobungozi, kunye nokuqinisekisa ukusebenza ngokukhuselekileyo.Zibekwe kufuphi ne-inverter kwaye zifuna indlela yokuhlukanisa ngesandla lonke uluhlu lwe-PV ngexesha lofakelo lwenkqubo okanye naluphi na ulondolozo olulandelayo.

Yeyiphi iMisebenzi yoKhuseleko yePV Array DC Isolator switch?

(1) Xa ufaka inkqubo ye-photovoltaic, umfaki ngokuqhelekileyo ucima i-DC switch kuqala ukuhlukanisa igalelo lepaneli yelanga kwi-inverter.Ngexesha le wiring kunye neplagi yeetheminali DC, amandla DC akaqhagamshelwanga kwicala DC inverter ukuthintela ukothuka zombane zomntu kunye nomonakalo kwi-inverter kunye nezixhobo ngasemva-isiphelo.Ke ngoko, xa ufaka inkqubo, sifuna i-PV array dc isolator ukwahlula amandla eDC phakathi kwe-inverter kunye nephaneli yebhetri.

(2) Kwisikhululo samandla e-photovoltaic, i-inverter yi "core center".Ukuze kuqinisekiswe ixesha elaneleyo lokuvelisa amandla, i-inverter ayinalo iqhosha lokuqala lokumisa.Ngethuba nje kukho ukukhanya (nangona kwimozulu yemvula), iipaneli zelanga zinokuvelisa umbane kwaye i-inverter inokusebenza ngokuzenzekelayo.Nangona kunjalo, oku kwakhona kuzisa ingxaki.Xa utshintsha okanye ulungisa i-inverter, nangona icala le-AC liye lacinywa yi-AC efakwe i-circuit breaker, icala le-DC lihlala linamandla.Kule meko, ukuba i-inverter ayinayo i-solar array dc isolator switch yokuhlukanisa amandla e-DC yeepaneli, kulula ukubangela ukutshitshiswa kombane kunye nomonakalo wezixhobo.

(3) Okwangoku, uninzi lwe-inverters kwimarike luchungechunge lwe-TL, oko kukuthi, akukho nto yodwa yombane ngaphakathi, kwaye kukho ithuba lokubuyela umva ukusuka kwicala le-AC ukuya kwicala le-DC.Ngexesha lokugcinwa, ukuba i-AC switch kunye ne-DC itshintshile yodwa ngokwasemzimbeni, inokukhuselwa ngokukhuselekileyo.

Iintlobo zoFakelo ezahlukeneyo

Kukho iintlobo ezi-5 zokufakela: Uhlobo lokuxhoma lomngxuma omnye, uhlobo lokufakwa kwePaneli, uhlobo lokunyusela uloliwe, uhlobo lokuxhoma isitshixo somnyango, kunye nohlobo lokuxhoma lwaNgaphandle.

Iimpawu ze-Slocable PV Array DC Isolators:

1. Ngokukodwa yenzelwe isicelo se-DC, i-related current range 16 ~ 630A, i-voltage range: ≤1500V, ifanelekile kwizicelo ezahlukeneyo;

2. Iindlela ezahlukeneyo zokufakela kunye noyilo lweemodyuli zinika ukuguquguquka kofakelo lwemveliso;

3. Uyilo lombane lokuzicoca, lunciphisa ukuxhathisa kunye nokusetyenziswa kwamandla, kunye nokwandisa ubomi benkonzo;

4. Inani leepali: 2 ~ 10 amanqanaba okuzikhethela;

5. Ixesha elininzi lokuvala: ngaphantsi kwe-5ms

6. Izinto ezifakwe ngaphandle kwe-UL94V-0 ze-flame retardant zisetyenzisiweyo, ezinokuthi zisetyenziswe kwiindawo ezisetyenziswayo ezinzima;

7. Ukuthobela imigangatho eyahlukeneyo (efana ne-IEC, UL, TUV, CE, CB, SAA, CCC, njl.)

I-Slocable inokuvelisa ii-PV zoluhlu lwe-isolator ezifanelekileyo kuluhlu olupheleleyo lwee-inverters zeentambo ukusuka kwi-1KW ukuya kwi-320KW.Ingumthengisi we-DC isolator switchs ngokuhambelana ne-IEC60947-3 (ed.3.2): 2015 kwaye ufumene isatifikethi se-UL.

Ezi mveliso ezihambelana nemigangatho yamva nje ye-photovoltaic zinokuhlangabezana neemfuno ezibanzi zemarike ye-photovoltaic yehlabathi kwaye inokusombulula amaxhala abathengi malunga nokhuseleko lwenkqubo kunye nokukhuselwa.I-Slocable iya kuqhubeka iqhuba uphando olunzulu ukubonelela imarike ngokhetho olwahlukeneyo nolungcono.
