一、 Iinkqubo zePhotovoltaic ziyaqhuma
Ngokugxininiswa okunyukayo ekukhuselweni kwendalo emhlabeni jikelele, iinkqubo ze-photovoltaic zisetyenziswe ngokubanzi kwiinkalo ezahlukeneyo. Kwiimarike zombane, iinkqubo ze-photovoltaic azikwazi ukubonelela ngombane kuphela kwizixeko, kodwa zibonelela ngokukhanyisa kunye neenkonzo zonxibelelwano kwiindawo ezikude. Ngelo xesha, iinkqubo ze-photovoltaic zineendleko eziphantsi zokufakela kunye neendleko zokusebenza eziphantsi, ngoko ke zithandwa ngamashishini amaninzi kunye nee-arhente zikarhulumente.
二、Iinverters zePhotovoltaic zineengxaki ekufuneka zoyiswe
I-photovoltaic inverter sisixhobo esiguqula ngoku ngokuthe ngqo okwenziwe ngamapaneli e-photovoltaic kwi-alternating current. Ibeka iliso kwi-voltage kunye nemveliso yangoku ngamaphaneli e-photovoltaic ngokusebenzisa i-algorithm yokulandelela amandla aphezulu, iqonda ukunyuka kwe-voltage kunye nokuwa kwangoku ngokuthe ngqo, kwaye iyiguqule ibe ngumbane othe ngqo okhoyo ngoku. Okulandelayo, i-inverter iguqula amandla e-DC kumandla e-AC usebenzisa itekhnoloji yokumodareyitha yobubanzi be-pulse ububanzi, kwaye iyigudise ngesihluzo esiphumayo ukuqinisekisa umgangatho kunye nokuzinza kwemveliso yangoku. Ekugqibeleni, i-inverter idibanisa imveliso ye-AC yamandla kwigridi yamandla ukuze ihlangabezane neemfuno zombane wendlu okanye wemizi-mveliso. Ngale ndlela, i-photovoltaic inverters idlala indima ebalulekileyo ekuguquleni amandla elanga kumbane onokusetyenziswa.
Okwangoku, i-1000 ~ 2200W i-inverter ye-photovoltaic eqhelekileyo esetyenziswe ekupheleni kwegalelo lenkqubo yokuvelisa amandla e-photovoltaic inomthamo we-voltage ephezulu ukuya kwi-580V. Nangona kunjalo, i-capacitor ye-500V ekhoyo ekhoyo ayinakukwazi ukuhlangabezana neemfuno ze-photovoltaic inverters. Phakathi kwabo, i-aluminium i-electrolytic capacitors idlala indima ebalulekileyo, engakwaziyo ukubonelela kuphela ngokucoca okufunekayo kunye nemisebenzi yokugcina, kodwa iqinisekisa ukuthembeka kunye nokusebenza kakuhle kwenkqubo yonke. Ukuba i-voltage ephumayo ayanelanga, iya kubangela ukuba i-capacitor ifudumale, iphule, kwaye ekugqibeleni yonakaliswe. Ngoko ke, kuyimfuneko ukuqwalasela ngokucophelela izinto ezahlukeneyo xa ukhetha i-electrolytic capacitor, kwaye ukhethe eyona mveliso ifanelekileyo ukuqinisekisa ukusebenza kakuhle kwenkqubo kwaye ufumane ukusebenza kakuhle.
三、I-Yongming high-voltage lead-type capacitors ixazulula imeko kaxakeka "yombane ophezulu".
Ukuze kulungiswe ingxaki ye-voltage ephezulu yee-inverters ze-photovoltaic, i-Shanghai Yongming iqalise i-high-voltage lead-type ye-LKZ series aluminium electrolytic capacitors. Usapho luneempawu zokusebenza ezichanekileyo kwaye lusebenza kuluhlu olubanzi lwee-voltages zokufakelwa, kubandakanywa i-peak voltages ukuya kwi-580V. Ukusebenza okugqwesileyo kwe-LKZ series capacitors kunokuphucula ukuzinza kunye nokusebenza kakuhle kwe-photovoltaic inverters kunye nokubonelela abathengi ngezona zisombululo ezilungileyo.
I-1, Isantya esiphezulu esinamandla kunye nokuchasana kwempembelelo: Uchungechunge lwe-LKZ lwe-aluminium electrolytic capacitors lunokufikelela kwi-voltage ye-600V, enokusingatha ngokulula i-voltage ephezulu kunye ne-current enkulu ngexesha lokuphuma.
I-2, i-Ultra-low-low-internal resistance and better low-low-temperatures I-40 ℃ ukusebenza kwe-capacitor ngexesha lokusebenza. Iimpawu zokushisa eziphantsi, ukwenzela ukuba i-capacitor ayiyi kuphumelela ekuqaleni komsebenzi wexesha elide.
3 kwangaxeshanye, phantsi kweemfuno zamandla afanayo, usebenzisa i-Yongming Larger umthamo we-electrolytic capacitors unokunciphisa iindleko zabathengi ngokwemigaqo ye-capacitance.
I-4, ukuthembeka okuphezulu: I-electrolytic capacitors ye-Yongming inika isiqinisekiso esibanzi ngakumbi sokuzinza kunye nokuthembeka kwamacandelo abalulekileyo e-elektroniki afana ne-photovoltaic inverters, okwenza ukusebenza kwayo yonke inkqubo ye-photovoltaic ihle kakhulu.
Ixabiso lombane: 550 ~ 600V
Uluhlu lwamandla: 82 ~ 220μF
Ubushushu bokusebenza: -40 ~ 105 ℃
Ubomi: 12000 ~ 15000H
四, Yenza ii-capacitor zasekhaya ezikumgangatho ophezulu kwaye uqhubele phambili kwimarike yamazwe ngamazwe
Njengecapacitor yasekhaya yasekhaya, i-Yongming yolwelo lwe-aluminium ekhokelela kwi-electrolytic capacitor ineenzuzo ezinkulu ekusetyenzisweni kwee-inverters ze-photovoltaic, inika isiqinisekiso esinamandla sokuzinza kwenkqubo ye-photovoltaic, kunye nokusebenza kwayo okubanzi kuthelekiseka ne-Japan capacitors. .
