Zvikamu zve photovoltaic system
1.PV system components PV system ine zvikamu zvinotevera zvinokosha.Photovoltaic modules inogadzirwa kubva kune photovoltaic masero kuita matete firimu mapaneru akaiswa pakati peiyo encapsulation layer.Inverter ndeyekudzosera iyo DC simba rinogadzirwa nePV module kuita grid-yakabatana AC simba.Bhatiri ndiro rinochengeta nekemikari magetsi akananga (DC).Photovoltaic mounts inopa rutsigiro rwekuisa iyo PV modules.
2. Mhando dzePV masisitimu dzinogona kukamurwa zvakanyanya kuita mhando mbiri.Grid-yakabatana system: iyo inobatsira yemhando iyi yehurongwa ndeyekuti hapana bhatiri rekuchengetedza, rakabatana zvakananga kune grid yenyika, haufanirwe kunetseka nezvekudzima kwemagetsi;off-grid system: off-grid system inoda bhatiri kuchengetedza simba, saka mutengo uchave wakakwira.
Mienzaniso yegridhi-yakabatana masisitimu uye off-grid masisitimu anoratidzwa mukuenzanisa:
Photovoltaic system wiring:
1. PV system series-parallel connection PV modules inogona kubatanidzwa mune zvakafanana kana munhevedzano maererano nezvinodiwa, uye inogonawo kubatanidzwa mumutsara-parallel musanganiswa.Semuenzaniso, 4 12V PV modules inoshandiswa kugadzira 24V off-grid system: 16 34V PV modules inoshandiswa kugadzira grid-yakabatana system ine zvikamu zviviri zvakatevedzana.
2. Kubatanidza zvikamu zve inverter mienzaniso.Huwandu hwezvikamu zvinogona kupetwa kune akasiyana mamodhi inverters ndeyechokwadi, uye nhamba yekubatanidza kune rimwe nerimwe boka rezvikamu inogona kugoverwa zvichienderana nenhamba yematavi inverter, sezvakaratidzwa mumufananidzo:
3. Inverter yekubatanidza nzira DC circuit breaker uye AC circuit breaker inofanira kuiswa paDC inopinza uye AC kubuda kwe inverter maererano.Kana paine boka rinopfuura rimwe remainverters kuti abatanidzwe panguva imwe chete, iyo DC terminal yeboka rega rega reinverters inofanirwa kubatanidzwa kune module zvakasiyana, uye iyo AC terminal inogona kubatanidzwa kune gidhi mukuwirirana, uye dhayamita yetambo. inofanira kukobvuswa maererano.
4. AC terminal grid yekubatanidza inowanzobatanidzwa kune grid nekambani yemagetsi, iyo yekuisa unit inoda chete kuchengetedza AC terminal mubhokisi remamita, uye isa disconnect switch.Kana muridzi wacho asingashandisi grid kana kuti asina kubvumirwa kubatanidza grid.Ipapo iyo yekumisikidza unit inoda kubatanidza iyo AC yekupedzisira kumucheto wezasi wemagetsi inlet switch.Mushandisi achada matatu-phase inverter kana akabatana kune matatu-chikamu simba.
Chikamu cheBracket:
Iyo bracket ye simenti yakadzika denga sement denga denga rinogona kukamurwa kuita zvikamu zviviri, imwe ndiyo yepasi chikamu chebhureki uye imwe yacho chikamu chebhureketi.Nheyo yebhuraketi yakagadzirwa nekongiri ine chiyero cheC30.Mabhuraketi anogadzirwa nevagadziri vakasiyana akasiyana, uye mabhureki anoshanda akasiyana zvichienderana neakasarudzika mamiriro esaiti.Chekutanga pane zvese, zviri nyore kunzwisisa zvakajairwa bracket zvinhu uye chimiro chechimwe nechimwe chikamu chekukurumidza kuisirwa mabhureki.
