Momwe mungasankhire zingwe zapakhomo za photovoltaic mwachuma

Mu photovoltaic system, kutentha kwa ACchingwendizosiyananso chifukwa cha malo osiyanasiyana omwe mizereyo imayikidwa. Mtunda pakati pa inverter ndi malo olumikizira gululi ndi wosiyana, zomwe zimapangitsa kutsika kwamagetsi kosiyanasiyana pa chingwe. Kutentha ndi kutsika kwa magetsi kudzakhudza kutayika kwa dongosolo. Choncho, m'pofunika momveka kupanga waya awiri a linanena bungwe panopa wa inverter, ndi mwatsatanetsatane zinthu zosiyanasiyana, kuti kuchepetsa ndalama koyamba wa siteshoni photovoltaic mphamvu ndi kuchepetsa mzere imfa ya dongosolo.
Popanga ndi kusankha zingwe, magawo aumisiri monga mphamvu yonyamulira yapano, voliyumu, ndi kutentha kwa chingwe zimaganiziridwa kwambiri. Pa unsembe, m'mimba mwake akunja, kupinda utali wozungulira, kuteteza moto, etc. chingwe amaganiziridwanso. Powerengera mtengo, ganizirani mtengo wa chingwe.
1. Kutulutsa kwamagetsi kwa inverter kuyenera kukhala kogwirizana ndi mphamvu yonyamula chingwe
Kutulutsa kwaposachedwa kwa inverter kumatsimikiziridwa ndi mphamvu. The single-phase inverter current = mphamvu/230, the three phase inverter current = mphamvu/(400*1.732), ndi ma inverter ena amathanso kuchulukitsidwa ndi nthawi 1.1.
Kuthekera kwamakono kwa chingwe kumatsimikiziridwa ndi zinthu, waya awiri ndi kutentha. Pali mitundu iwiri ya zingwe: waya wamkuwa ndi waya wa aluminiyamu, iliyonse yomwe ili yothandiza. Pakuwona chitetezo, tikulimbikitsidwa kugwiritsa ntchito waya wamkuwa pakutulutsa chingwe cha AC cha inverter, ndipo waya wofewa wa BVR nthawi zambiri amasankhidwa pagawo limodzi. Waya, PVC kutchinjiriza, mkuwa pachimake (zofewa) nsalu voteji kalasi kalasi ndi 300/500V, magawo atatu kusankha 450/750 voteji (kapena 0.6kV/1kV) kalasi YJV, YJLV irradiated XLPE insulated PVC sheathed mphamvu chingwe, ubale pakati pa kudulidwa kwa kondakitala ndi kutentha, ngati kutentha kozungulira kuli kopitilira 35 ° C, ndikololedwa. chapano chiyenera kuchepetsedwa ndi pafupifupi 10% pakuwonjezeka kulikonse kwa kutentha kwa 5°C; ngati kutentha kozungulira kumakhala kotsika kuposa 35 ° C, kutentha Pamene kutentha kumatsika ndi 5 ° C, mphamvu yovomerezeka ikhoza kuwonjezeka ndi pafupifupi 10%. Nthawi zambiri, ngati chingwecho waikidwa m'nyumba mpweya wokwanira malo.
2. Chingwekamangidwe kachuma
M'malo ena, inverter ili kutali ndi malo olumikizira gridi. Ngakhale chingwecho chikhoza kukwaniritsa zofunikira za mphamvu zomwe zilipo panopa, kutaya kwa mzere kumakhala kwakukulu chifukwa cha chingwe chachitali. Kukula kwakukulu, kumachepetsa kukana kwamkati. Komanso ganizirani mtengo wa chingwe, awiri akunja a inverter AC linanena bungwe losindikizidwa ma terminals.
