Amacandelo enkqubo ye-photovoltaic
Amacandelo enkqubo ye-1.PV Inkqubo ye-PV iquka la macandelo abalulekileyo alandelayo. Iimodyuli ze-Photovoltaic zenziwa ukusuka kwiiseli ze-photovoltaic kwiipaneli zefilimu ezincinci ezibekwe phakathi kwe-encapsulation layer. I-Inverter kukubuyisela umva amandla e-DC aveliswa yimodyuli ye-PV kumbane we-AC oqhagamshelwe kwigridi. Ibhetri sisixhobo esigcina amandla ombane akhoyo ngokwekhemikhali. Ukunyuka kwe-Photovoltaic kunika inkxaso yokubeka iimodyuli zePV.
2. Iindidi zeenkqubo zePV zinokuhlelwa ngokubanzi zibe ziintlobo ezimbini. Inkqubo edibeneyo yegridi: inzuzo yolu hlobo lwenkqubo kukuba akukho bhetri yokugcina ibhetri, exhunywe ngokuthe ngqo kwigridi yesizwe, musa ukukhathazeka malunga nokuphuma kwamandla; inkqubo ye-off-grid: inkqubo ye-off-grid ifuna ibhetri ukugcina amandla, ngoko ke ixabiso liya kuba phezulu.
Imizekelo yeenkqubo eziqhagamshelwe kwigridi kunye neenkqubo ezingekho kwigridi ziboniswa xa kuthelekiswa:
Umbane wenkqubo ye-Photovoltaic:
1. Iimodyuli ze-PV zenkqubo ye-PV-parallel uxhumano lwe-PV zinokudibaniswa ngokuhambelanayo okanye kwi-series ngokweemfuno, kwaye zinokudibaniswa kwi-series-parallel mix. Ngokomzekelo, iimodyuli ze-4 12V ze-PV zisetyenziselwa ukuyila inkqubo ye-24V ye-off-grid: iimodyuli ze-16 34V ze-PV zisetyenziselwa ukuyila inkqubo edibeneyo yegridi equka iinxalenye ezimbini zechungechunge.
2. Amacandelo okudibanisa kwiimodeli ze-inverter. Inani lamacandelo anokuthi adityaniswe kwiimodeli ezahlukeneyo ze-inverters liqinisekile, kwaye inani loqhagamshelo kwiqela ngalinye lamacandelo linokwabiwa ngokwenani lamasebe e-inverter, njengoko kubonisiwe kumfanekiso:
3. Indlela yokudibanisa i-inverter ye-DC i-circuit breaker kunye ne-AC circuit breaker kufuneka ifakwe kwi-input ye-DC kunye nemveliso ye-AC ye-inverter ngokulandelanayo. Ukuba kukho ngaphezu kweqela elinye le-inverters ukuba lidityaniswe ngexesha elifanayo, i-terminal ye-DC yeqela ngalinye le-inverters kufuneka ixhunywe kwimodyuli ngokwahlukileyo, kwaye i-terminal ye-AC inokudibaniswa kwigridi ngokufanayo, kwaye ububanzi bekhebula kufuneka bugqitywe ngokufanelekileyo.
4. Uxhumo lwegridi ye-AC ye-terminal ixhunywe ngokubanzi kwigridi yinkampani yonikezelo lwamandla, iyunithi yokufakela idinga kuphela ukugcina i-terminal ye-AC kwibhokisi yemitha, kwaye ufake i-switch switch. Ukuba umnini akasebenzisi igridi okanye akavunywanga uxhulumaniso lwegridi. Emva koko iyunithi yokufakela kufuneka idibanise isiphelo se-AC kwisiphelo esisezantsi sokutshintsha kwamandla okungena. Umsebenzisi uya kufuna inverter yesigaba sesithathu ukuba uqhagamshelwe kumandla amanqanaba amathathu.
Inxalenye yesibiyeli:
Isibiyeli sesamente esisicaba sesamente uphahla olusicaba lunokwahlulwa lube ngamacandelo amabini, enye yinxalenye yesiseko sesibiyeli kwaye enye yinxalenye yesibiyeli. Isiseko se-bracket senziwe ngekhonkrithi kunye ne-C30 eqhelekileyo. Iibrakethi eziveliswa ngabavelisi abahlukeneyo zihluke, kwaye iibhakethi ezisebenzayo zihluke ngokweemeko ezizodwa zesayithi. Okokuqala, kulungele ukuqonda izinto eziqhelekileyo ze-bracket kunye nemilo yecandelo ngalinye lokufakwa ngokukhawuleza kweebakaki.
