Nigute ushobora guhitamo umugozi ukwiye？

Mu myaka yashize, tekinoroji yainganda zifotorayateye imbere byihuse kandi byihuse.Imbaraga za module imwe zabaye nini kandi nini, kandi ikigezweho cyumugozi nacyo cyabaye kinini kandi kinini.Ibiriho imbaraga-modules nyinshi bigeze kuri 17A.Kubijyanye nigishushanyo mbonera cya sisitemu, ikoreshwa ryibikoresho bifite ingufu nyinshi hamwe nu mwanya wabitswe neza birashobora kugabanya igiciro cyambere cyishoramari nigiciro cya kilowatt-isaha ya sisitemu.Igiciro cyinsinga za AC na DC muri sisitemu ntabwo kiri hasi.Nigute gushushanya no gutoranya bigomba gukorwa kugirango ibiciro bigabanuke?

1. Guhitamo insinga za DC

Umugozi wa DC washyizwe hanze.Mubisanzwe birasabwa guhitamo insinga zidasanzwe zifotora zahujwe nimirasire.Nyuma yo gukwirakwiza imirasire ya elegitoronike ifite ingufu, imiterere ya molekuline yumurongo wibikoresho bya insulasiyo ihinduka kuva kumurongo ugana kumurongo wa molekuliyumu yimiterere itatu, kandi urwego rwo kurwanya ubushyuhe rwiyongera kuva kuri 70 ° C kugeza kuri 90 ° C, 105 ° C, 125 ° C, 135 ° C, Ndetse kugeza kuri 150 ° C, ubushobozi bwo gutwara ubu burenze 15-50% kurenza ubw'insinga zifite ibisobanuro bimwe.Irashobora kwihanganira ihinduka rikabije ryubushyuhe hamwe nisuri yimiti kandi irashobora gukoreshwa hanze mumyaka irenga 25.Mugihe uhisemo insinga za DC, hitamo ibicuruzwa mubakora bisanzwe bafite ibyemezo bijyanye kugirango wemeze gukoresha igihe kirekire hanze.

Kugeza ubu, ikoreshwa cyaneamashanyarazi ya DCni PV1-F1 * 4 4 metero kare.Ariko, hamwe no kwiyongera kwubu modul ya Photovoltaque no kwiyongera kwingufu za inverter imwe, uburebure bwumugozi wa DC nabwo buriyongera.Metero kare 6 Gukoresha insinga za DC nabyo biriyongera.

Ukurikije ibisobanuro bifatika, birasabwa ko muri rusange gutakaza DC bifotora bitagomba kurenga 2%.Twifashishije ibipimo ngenderwaho mugushushanya uburyo bwo guhitamo insinga za DC.Imirongo irwanya PV1-F1 * 4mm² Umugozi wa DC ni 4,6mΩ / metero, naho umurongo wa PV6mm² DC ni 3.1 mΩ / metero, ukeka ko module ya DC ikora voltage ari 600V, 2% igabanuka rya voltage ni 12V, ukeka ko ko module iriho ari 13A, ukoresheje umugozi wa 4mm² DC, intera iri hagati yimpera ya kure ya module na inverter irasabwa kutarenza metero 120 (umugozi umwe, (usibye inkingi nziza nibibi), niba intera irenze iyi intera, birasabwa guhitamo umugozi wa 6mm² DC, ariko birasabwa ko intera iri hagati yimpera yanyuma yibigize na inverter itagomba kurenga metero 170.

2. Kubara insinga ya Photovoltaque

Kugirango ugabanye ibiciro bya sisitemu, ibigize nainverteri yumuriro wamashanyarazini gake cyane muburyo bwa 1: 1.Ahubwo, ibice bimwe birenze urugero byashizweho hashingiwe kumiterere yumucyo, ibikenerwa byumushinga, nibindi. 158A.Umugozi wa AC urashobora gutoranywa hashingiwe kumasoko ntarengwa asohoka yainverter.Kuberako nubwo ibice byinshi byashyizweho, AC yinjiza ya inverter ntizigera irenga umusaruro mwinshi wa inverter.

3. Inverter AC isohoka ibipimo

Ubusanzwe insinga z'umuringa wa AC kuri sisitemu ya Photovoltaque harimo BVR na YJV.BVR bisobanura intoki z'umuringa PVC zifite insinga zoroshye, YJV ihuza imiyoboro ya polyethylene.Mugihe uhitamo, witondere urwego rwa voltage nurwego rwubushyuhe bwa kabili.. / 1kV, bisobanura metero kare 25 ya insinga.Multi-core yagoretse ishami ryibisobanuro byerekana, umubare winsinga mumuzingo umwe * kwambukiranya izina, nka: 3 * 50 + 2 * 25mm 0,6 / 1KV, bivuze insinga eshatu nzima 50, insinga imwe itagira aho ibogamiye na insinga ya kare kare 25.
