Yintoni umahluko phakathi kwe-AC kunye ne-DC yebhokisi yokuhlanganisa?

I-AC (Alternating Current) kunye ne-DC (Ngqo ngoku)iibhokisi zokudibanisasebenza iinjongo ezahlukeneyo kwiinkqubo zombane, ngakumbi kwiinkqubo zamandla ahlaziyekayo njengofakelo lwe-solar photovoltaic (PV).

Iibhokisi zokudibanisa i-AC zisetyenziselwa ukudibanisa iisekethe ezininzi ze-AC ezivela kwii-inverters zelanga okanye eminye imithombo ye-AC. Ezi sekethe ziphethe umsinga otshintshanayo, luhlobo lwangoku olusetyenziswa rhoqo kwiinkqubo zombane zasekhaya kunye nezorhwebo.

DC Combiner ibhokisi:Iibhokisi zokudibanisa DC, ngakolunye uhlangothi, zisetyenziselwa ukudibanisa iintambo ezininzi ze-DC okanye uluhlu lweepaneli zelanga ngaphambi kokuba zidibaniswe ne-solar inverter. Le micu okanye i-arrays ivelisa i-current ngqo, luhlobo lwangoku oluveliswa ngamapaneli elanga.

Iibhokisi zokudibanisa i-AC zidla ngokuphatha amanqanaba ombane asezantsi kuba zijongana nemveliso evela kwii-inverters, eziguqula i-DC ukuya kwi-AC kumbane olungele uqhagamshelo lwegridi (umzekelo, i-120V, 240V, 480V).

Ibhokisi ye-DC Combiner: Iibhokisi zokuhlanganisa i-DC kufuneka zilawule amanqanaba aphezulu ombane kuba zijongene nemveliso ye-DC eluhlaza esuka kwiipaneli zelanga, ezinokususela kumakhulu aliqela e-volts ukuya ngaphezulu kwe-1,000 volts ngokuxhomekeke kubumbeko kunye nobukhulu benkqubo.

Izixhobo ezikwiibhokisi zokuhlanganisa i-AC, ezinje ngezaphuli zesekethe okanye iifuse, ngokwesiqhelo zithelekelwa usetyenziso lwe-AC kwaye zinokuba neenkcukacha ezahlukeneyo xa zithelekiswa nezo zisetyenziswa kwiibhokisi ze-DC zokuhlanganisa.

Ibhokisi ye-DC Combiner: Izixhobo ezikwiibhokisi zokuhlanganisa ze-DC, ezibandakanya iifuse, iziqhekezi zesekethe, kunye nezikhuseli ze-surge, kufuneka ziyilwe ngokukodwa kwaye zilinganiswe kwizicelo ze-DC ngenxa yeempawu ezahlukeneyo zombane we-DC.

Iingqwalasela zoKhuseleko:

Iingqwalasela zokhuseleko kwiibhokisi zokudibanisa i-AC zijolise ekukhuseleni ngokugqithisekileyo kunye neesekethe ezimfutshane, kunye nokubonelela ngeendlela zokuzihlukanisa kunye nokuqhawula njengoko kufunwa iikhowudi zombane.

Ukongeza kwi-overcurrent kunye nokhuseleko lwesekethe emfutshane, amanyathelo okhuseleko kwiibhokisi ze-DC zokudibanisa zikwabandakanya ukukhuselwa kwi-arcing kunye nokusilela kwe-insulation ngenxa yombane ophezulu obandakanyekayo.

Isishwankathelo, i-AC kunyeIibhokisi zokudibanisa DCziyahluka ngokohlobo lwangoku abaluphathayo, amanqanaba ombane, ukhetho lwecandelo, kunye nokuqwalaselwa kokhuseleko. Badlala indima eyahlukileyo kwiinkqubo zamandla avuselelekayo kwaye kufuneka zikhethwe kwaye zifakwe ngokufanelekileyo ngokweemfuno ezithile zenkqubo.
