Kwinkqubo ye-photovoltaic, ukushisa kwe-ACintamboyahlukile kwakhona ngenxa yeemeko ezahlukeneyo apho iilayini zifakwe khona.Umgama phakathi kwe-inverter kunye nendawo yokudibanisa igridi iyahluka, okubangela ukuhla kwamandla ohlukeneyo kwikhebula.Bobabini ubushushu kunye nokwehla kwamandla ombane kuya kuchaphazela ukulahleka kwenkqubo.Ngoko ke, kuyimfuneko ukuyila ngokufanelekileyo i-wire diameter ye-output current ye-inverter, kunye nokuqwalasela ngokubanzi izinto ezahlukeneyo, ukwenzela ukunciphisa utyalo-mali lokuqala lwesikhululo samandla e-photovoltaic kunye nokunciphisa ukulahleka komgca wenkqubo.
Xa uyila kunye nokukhetha iintambo, iiparitha zobugcisa ezifana nomthamo wokuthwala wangoku, i-voltage, kunye nobushushu bekhebula ziqwalaselwa ikakhulu.Ngexesha lofakelo, ububanzi bangaphandle, i-radius yokugoba, ukuthintela umlilo, njl njl.Xa ubala iindleko, qwalasela ixabiso lentambo.
1. Imveliso yangoku ye-inverter kufuneka ihambelane nomthamo wangoku wokuthwala ikhebula
Imveliso yangoku ye-inverter inqunywe ngamandla.I-inverter yesigaba esisodwa samanje = amandla / i-230, i-inverter yesigaba sesithathu yangoku = amandla / (400 * 1.732), kunye nezinye ii-inverters zinokugqithiswa ngamaxesha e-1.1.
Umthamo wangoku wokuthwala ikhebula unqunywe yimpahla, i-wire diameter kunye neqondo lokushisa.Kukho iintlobo ezimbini zeentambo: ucingo lobhedu kunye nocingo lwe-aluminium, nganye iluncedo.Ngokombono wokhuseleko, kuyacetyiswa ukuba kusetyenziswe ucingo lobhedu kwimveliso ye-AC cable ye-inverter, kunye ne-BVR yocingo oluthambileyo lukhethwa ngokubanzi kwisigaba esisodwa.Ucingo, ukugqunywa kwePVC, undoqo wobhedu (othambileyo) welaphu lombane wombane weklasi yi-300/500V, inqanaba lesithathu likhetha i-450/750 yombane (okanye 0.6kV/1kV) iklasi YJV, YJLV irradiated XLPE insulated PVC Sheathed power cable, ubudlelwane phakathi i-cutoff ye-conductor kunye neqondo lokushisa, ukuba ubushushu be-ambient bungaphezulu kwe-35 ° C, umbane ovumelekileyo kufuneka uncitshiswe malunga ne-10% kwi-5 ° C yokwanda kweqondo lokushisa;ukuba iqondo lokushisa eliphantsi lingaphantsi kwe-35 ° C, iqondo lokushisa Xa ubushushu buhla ngo-5 ° C, umbane ovumelekileyo unokunyuswa malunga ne-10%.Ngokuqhelekileyo, ukuba ikhebula lifakwe kwindawo yokungena ngaphakathi.
2. Intambouyilo lwezoqoqosho
Kwezinye iindawo, i-inverter ikude nendawo yokudibanisa igridi.Nangona i-cable ingahlangabezana neemfuno zomthamo wangoku wokuthwala, ukulahleka komgca kukhulu ngenxa yekhebula elide.Inkulu i-warp, iyancipha ukuchasana kwangaphakathi.Kodwa kwakhona qwalasela ixabiso lentambo, i-diameter yangaphandle ye-inverter AC imveliso etywinwe iitheminali.
