I-PV array DC isolator, eyaziwa ngokuba yi-DC disconnect switch okanye i-DC isolator switch, sisixhobo esisetyenziswe kwiinkqubo ze-photovoltaic (PV) ukubonelela ngeendlela zokuqhawula umbane othe ngqo (DC) owenziwe ngamapaneli elanga ukusuka kuyo yonke inkqubo.Iyingxenye yokhuseleko oluyimfuneko oluvumela abasebenzi bolondolozo okanye abaphenduli bexesha likaxakeka ukuba bahlukanise uluhlu lwe-PV kwi-inverter kunye namanye amacandelo ukulungiselela ukugcinwa okanye ukuxazulula iingxaki.
Nanga amanye amanqaku aphambili malunga nePV array DC isolator:
Injongo: Eyona njongo iphambili ye-PV array DC isolator kukubonelela ngendlela ekhuselekileyo yokuqhawula umbane weDC oveliswe ziipaneli zelanga ukusuka kuyo yonke inkqubo.Iqinisekisa ukuba akukho mandla e-DC akhoyo kwicala lenkqubo ngexesha lolondolozo okanye kwimeko kaxakeka.
Indawo: I-PV array DC isolators iqhele ukufakwa kufutshane neepaneli zelanga okanye kwindawo apho i-DC wiring esuka kwiipaneli ingena kwisakhiwo okanye igumbi lezixhobo.Ivumela ukufikelela lula kunye nokuqhawulwa ngokukhawuleza kwe-PV uluhlu.
Amanqaku ombane: I-PV array DC i-isolators ilinganiswe ukuphatha amandla ombane kunye namanqanaba angoku enkqubo ye-PV.Ukulinganisa kufuneka kuhambelane okanye kudlule i-voltage ephezulu kunye ne-current ye-PV array ukuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo.
Ukusebenza ngesandla: PV array DC isolators zidla ngokuqhutywa ngesandla.Zingavulwa okanye zicinywe ngokuphethula iswitshi okanye ngokujikelezisa isiphatho.Xa i-isolator ikwindawo evaliweyo, iphula isekethe ye-DC kwaye ihlukanise uluhlu lwe-PV ukusuka kuyo yonke inkqubo.
Iingqwalasela zokhuseleko: PV array DC isolators ziyilwe ngokhuseleko engqondweni.Basoloko beneempawu ezifana neziphatho ezitshixwayo okanye iindawo ezivaliweyo ukuthintela ukufikelela okungagunyaziswanga okanye ukuphazamisa.Ezinye i-isolator nazo zinezibonakaliso ezibonakalayo zokubonisa isimo sokutshintsha, esibonisa ukuba uluhlu lwe-PV luxhunyiwe okanye lunqanyuliwe.
Ukuthotyelwa kwemigangatho: I-PV array DC abahlukanisi kufuneka bahambelane nemigangatho efanelekileyo kunye nemimiselo, njengeKhowudi yoMbane yeSizwe (NEC) okanye imigangatho yeKhomishoni yoMbane yeHlabathi (i-IEC), ngokuxhomekeke kulawulo.Ukuthotyelwa kuqinisekisa ukuba i-isolator iyahlangabezana neemfuno eziyimfuneko zokhuseleko.
Kubalulekile ukubonisana nomntu osebenza ngombane oqeqeshiweyo okanye isifakeli selanga xa ukhetha kwaye ufaka i-PV array DC isolator ukuqinisekisa ubungakanani obufanelekileyo, ukubekwa, kunye nokuthobela iikhowudi zombane zasekhaya kunye nemimiselo,WAMKELEKILE ke ukuba udibane nathi NGEMFUNO YAKHO EKHETHEKILEYO: https://www.cncele.com/
