一、Amasistimu e-Photovoltaic ayathuthuka
Ngokugcizelelwa okwandayo ekuvikelweni kwemvelo emhlabeni wonke, izinhlelo ze-photovoltaic zisetshenziswe kabanzi emikhakheni ehlukahlukene. Emakethe kagesi, izinhlelo ze-photovoltaic azikwazi ukuhlinzeka ngogesi emadolobheni kuphela, kodwa futhi zinikeze izinsizakalo zokukhanyisa nokuxhumana ezindaweni ezikude. Ngesikhathi esifanayo, izinhlelo ze-photovoltaic zinezindleko eziphansi zokufaka kanye nezindleko zokusebenza eziphansi, ngakho-ke zithandwa ngamabhizinisi amaningi kanye nama-ejensi kahulumeni.
二、Ama-inverters e-Photovoltaic anezinkinga okufanele zinqotshwe
I-photovoltaic inverter iyithuluzi eliguqula okwamanje eliqondile elikhiqizwa amaphaneli e-photovoltaic libe lamanje elishintshayo. Iqapha i-voltage kanye nokuphumayo kwamanje ngamaphaneli e-photovoltaic ngokusebenzisa i-algorithm yokulandelela iphuzu lamandla aphezulu, ibona ukukhuphuka nokwehla kwe-voltage yamanje eqondile, futhi iyiguqule ibe amandla amanje azinzile aqondile. Okulandelayo, isiguquli siguqula amandla e-DC sibe amandla e-AC sisebenzisa ubuchwepheshe bokumodudula kwe-high-frequency pulse wide, futhi sibushelelezi ngesihlungi esiphumayo ukuze kuqinisekiswe ikhwalithi nokuzinza kokuphumayo kwamanje. Ekugcineni, i-inverter ixhuma amandla e-AC okukhiphayo kugridi yamandla ukuze ihlangabezane nezidingo zikagesi wasendlini noma wezimboni. Ngale ndlela, ama-photovoltaic inverters adlala indima ebalulekile ekuguquleni amandla elanga abe ngugesi osebenzisekayo.
Njengamanje, isiguquli se-photovoltaic esingu-1000 ~ 2200W esivamile esisetshenziswa ekugcineni kokufaka kwesistimu yokuphehla amandla e-photovoltaic sinomthamo omkhulu ophumayo ongafika ku-580V. Kodwa-ke, i-500V ekhona yokukhipha i-capacitor ayikwazi ukuhlangabezana nezidingo ze-photovoltaic inverters. Phakathi kwabo, i-aluminium electrolytic capacitors idlala indima ebalulekile, engakwazi ukunikeza kuphela imisebenzi edingekayo yokuhlunga nokugcina, kodwa futhi iqinisekise ukwethembeka nokusebenza kahle kwalo lonke uhlelo. Uma i-voltage ephumayo inganele, izokwenza ukuthi i-capacitor ishise, iphule, futhi ekugcineni ilimale. Ngakho-ke, kubalulekile ukucabangela ngokucophelela izici ezihlukahlukene lapho ukhetha i-electrolytic capacitor, futhi ukhethe umkhiqizo ofaneleka kakhulu ukuze uqinisekise ukusebenza kahle kwesistimu futhi uthole ukusebenza okuhle kakhulu.
三、 I-Yongming high-voltage lead-type capacitor ixazulula isimo esiphuthumayo "samandla kagesi aphezulu".
Ukuze kuxazululwe inkinga ye-voltage ephezulu yama-inverters e-photovoltaic, i-Shanghai Yongming yethula uhlobo oluphambili lwe-LKZ oluwuchungechunge lwe-aluminium electrolytic capacitor ephezulu. Umndeni unezici zokusebenza ezinembile futhi usebenza phezu kwebanga elibanzi lama-voltage okokufaka, okuhlanganisa ama-voltage aphezulu afika ku-580V. Ukusebenza okuhle kakhulu kwe-LKZ series capacitors kungathuthukisa ukuzinza nokusebenza kahle kwe-photovoltaic inverters futhi kunikeze amakhasimende izixazululo ezingcono kakhulu.
I-1, Ukuhlinzwa okuqinile okunamandla kanye nokumelana nomthelela: I-LKZ yochungechunge lwe-aluminium electrolytic capacitor ingafinyelela ku-600V voltage, engaphatha kalula i-voltage ephakeme kanye nomthamo omkhulu wamanje ngesikhathi sokuphuma.
I-2, Ukumelana ne-Ultra-low kwangaphakathi kanye nezici ezingcono ezisezingeni lokushisa eliphansi: Uma kuqhathaniswa nama-capacitor aseJapane e-specitor efanayo, i-impedance ye-Yongming capacitors iyancipha cishe ngo-15% ~ 20%, okuqinisekisa ukukhuphuka okuncane kwezinga lokushisa, ukumelana nokuguquguquka okukhulu kanye - Ukusebenza kwe-40 ℃ kwe-capacitor ngesikhathi sokusebenza. Izici zokushisa eziphansi, ukuze i-capacitor ingaphumeleli ekuqaleni komsebenzi wesikhathi eside.
3, Higher umthamo ukuminyana: Yongming aluminium electrolytic capacitor angaphezu kuka-20% ezinkulu kunama-capacitor Japanese of esibekiweko efanayo kanye nosayizi, nge ephakeme umthamo kwabantu kanye nomphumela ongcono wokuhlunga; ngesikhathi esifanayo, ngaphansi kwezidingo ezifanayo zamandla, ukusebenzisa i-Yongming Larger umthamo we-electrolytic capacitors kunganciphisa izindleko zamakhasimende ngokuya kwamandla.
I-4, Ukuthembeka okuphezulu: Ama-electrolytic capacitor e-Yongming anikeza isiqinisekiso esibanzi sokuzinza nokuthembeka kwezingxenye ze-elekthronikhi ezibalulekile ezifana nama-inverters e-photovoltaic, okwenza ukusebenza kwalo lonke uhlelo lwe-photovoltaic lube luhle kakhulu.
I-voltage elinganiselwe: 550 ~ 600V
Ibanga lamandla: 82~220μF
Izinga lokushisa lokusebenza: -40 ~ 105 ℃
Isikhathi sokuphila: 12000 ~ 15000H
四, Dala ama-capacitor asekhaya asezingeni eliphezulu futhi uthuthukele emakethe yamazwe ngamazwe
Njenge-capacitor emisha yasekhaya, i-aluminium ehamba phambili ye-aluminium electrolytic capacitor ewuketshezi ye-Yongming inezinzuzo ezinkulu ekusetshenzisweni kwezishintshi ze-photovoltaic, ihlinzeka ngesiqinisekiso esiqinile sokuzinza kwesistimu ye-photovoltaic, kanye nokusebenza kwayo okuphelele kuqhathaniswa nalokho kwama-capacitor aseJapane. .
