Imboni yokugcina amandla iyingxenye ebalulekile yesistimu yesimanje yamandla. I-inverter idlala izindima eziningi ohlelweni lwesimanje lokugcina amandla, okuhlanganisa ukuguqulwa kwamandla, ukulawula nokuxhumana, ukuvikelwa kokuhlukaniswa, ukulawula amandla, ukushaja okuphindwe kabili nokukhipha, ukulawula okuhlakaniphile, ukuvikela okuningi nokuhambisana okuqinile, okwenza i-inverter ibe enye yezingxenye ezibalulekile ezibalulekile zohlelo lokugcina amandla.
Ama-inverters okugcina amandla ngokuvamile akhiwa amasistimu okufaka, okukhiphayo nokulawula. Ama-Capacitor adlala indima ku-inverter, okuhlanganisa ukuqiniswa kwe-voltage nokuhlunga, ukugcinwa kwamandla nokukhululwa, ukuthuthukisa isici samandla, ukuvikela kanye nokushelela i-DC pulsation. Le misebenzi ihlangene iqinisekisa ukusebenza okuzinzile kanye nokusebenza kahle okuphezulu kwe-inverter. Kuzinhlelo zokugcina amandla, kungathuthukisa ukusebenza kahle okuphelele kanye nokuzinza kwesistimu.
Izinzuzo zama-capacitor e-YMIN kuma-inverter
Ukuminyana komthamo omkhulu:
I-inverter ithola ugesi okhiqizwe amandla avuselelekayo njengamaphaneli elanga noma ama-wind turbines futhi iwuguqule ibe uhlobo lukagesi oluhlangabezana nesidingo. Kule nqubo, njengoba umthamo wamanje ungase ukhuphuke ngokushesha, i-inverter idinga ukuba namandla anamandla okulawula amandla ukuze kuqinisekiswe ukuphuma okubushelelezi kukagesi.
I-YMIN aluminium electrolytic capacitorsibe nenzuzo yokuminyana komthamo omkhulu, ongagcina ukushajwa okwengeziwe ngevolumu efanayo, ihlangabezane ngokugcwele nesidingo somthwalo wamanje esingase senyuke ngokushesha. Ekusebenzeni kwe-inverter, lesi sici siqinisekisa ukuphuma okubushelelezi kwamandla kagesi.
Ukumelana okuphezulu kwe-ripple kwamanje:
Ngesikhathi sokusebenza kwe-inverter, uma ukulungiswa kwesici samandla kungenziwanga, okwamanje ekuphumeni kwayo kungase kube nenani elikhulu lezingxenye ze-harmonic. I-YMIN aluminium electrolytic capacitor, enokumelana nochungechunge olulinganayo oluphansi (ESR) kanye nezici ezinhle kakhulu zemvamisa ephezulu, inganciphisa ngempumelelo okuqukethwe kwe-harmonic, ingahlangani nje nesidingo somthwalo wamandla ekhwalithi ephezulu we-AC, kodwa futhi iqinisekise ukuthi inverter ihambisana nezindinganiso ezifanele zokufinyelela igridi, ukunciphisa ukuphazamiseka kanye nomthelela omubi kugridi.
Ngaphezu kwalokho, ohlangothini lokufakwayo lwe-DC lwe-inverter, ama-YMIN capacitor, ngobuningi bawo obuphezulu be-capacitance kanye nokusebenza okuhle kakhulu kokuhlunga, angaqhubeka nokuhlunga umsindo nokuphazamiseka kokunikezwa kwamandla we-DC okokufaka, ukuqinisekisa ukuthi okokufaka kwamanje kuhlanzekile, ngaleyo ndlela kunciphise umthelela wezimpawu zokuphazanyiswa ezingxenyeni ezilandelayo zesekethe ye-inverter futhi ithuthukise ngokugcwele ukusebenza kahle kohlelo lokusebenza.
Inzuzo yokumelana ne-voltage ephezulu:
Ngenxa yoshintsho ekukhanyeni kokukhanya, i-voltage ephumayo yesistimu ye-photovoltaic ingase ingazinzi, futhi amadivayisi we-semiconductor yamandla ku-inverter azophinde akhiqize ama-voltage kanye nama-spikes amanje phakathi nenqubo yokushintsha. Lawa ma-spikes angabangela umonakalo kumadivayisi kagesi. Ngakho-ke, i-buffer capacitor idlala indima ebalulekile ekumunceni ama-voltage nama-spikes amanje kanye nokuvikela imishini yamandla ku-voltage eyeqile noma ukushaqeka kwamanje. Ngesikhathi esifanayo, i-capacitor ingakwazi ukushelela izinguquko ku-voltage kanye namanje, ukunciphisa ukulahlekelwa kwamandla ngesikhathi senqubo yokushintsha, futhi ngaleyo ndlela ithuthukise ukusebenza kahle kokuguqulwa kanye nokuzinza okuphelele kwe-inverter.
YMINIsincomo sokukhetha i-capacitor ku-inverter:
Fingqa:
YMIN capacitorsathuthukise ngokujulile ukusebenza kwama-inverter ezinhlelweni zokugcina amandla anezici zawo ezinhle kakhulu ezifana nokumelana nogesi ophezulu, ukuminyana okuphezulu, i-ESR ephansi, nokumelana okuqinile kwe-ripple yamanje. Akugcini nje ukunciphisa ukulahlekelwa ohlelweni lokuguqulwa kwamandla ngokusebenzisa izici ezinhle kakhulu zokuhlunga kanye ne-voltage regulation, kodwa futhi ingalungisa ngokuzinzile i-voltage, yamanje kanye nemvamisa ukuze kuqinisekiswe ukuphuma kwesistimu okuthembekile. Ngasikhathi sinye, ama-capacitor amunca ngokushesha ukushaqeka kwesikhashana kanye nama-voltage abushelelezi, athuthukisa ukulwa nokuphazanyiswa kanye nokuzinza kwesistimu. Ngaphezu kwalokho, ama-capacitor e-YMIN asekela kahle ukugcinwa kwamandla nokukhululwa phakathi nenqubo yokushaja nokukhipha amandla, akhulise ukusebenza kahle kokusetshenziswa kwamandla kwesistimu yokugcina amandla futhi asize lonke uhlelo ukuba lufinyelele ukusebenza kahle kokuguqulwa okuphezulu, ukuzinza okuqinile, nokulahlekelwa kwamandla okuphansi.
