Ukukhuthaza intuthuko yobuchwepheshe bokugcina amandla kanye nokwenza ngcono ukusetshenziswa kwamandla: ama-capacitor e-YMIN

Enkathini entsha yamandla, ukukhula okusheshayo kwezinhlelo zamandla kuye kwaholela ekuthuthukisweni okusheshayo kwezinhlelo zokugcina amandla.

Ezinhlelweni zokugcina amandla, izidingo zamandla nesivinini sokuphendula kwezingxenye ezibalulekile (ezifana nama-inverter, ama-converter, izinhlelo zokuphatha amabhethri, njll.) zikhula njalo, okuletha inselele enkulu ezingxenyeni ze-elekthronikhi. Ama-capacitor anokusebenza okungcono, ubuningi bomthamo ophezulu kanye nokuqina okuqinile ayadingeka ukusekela izinhlelo zokugcina amandla ukuze kugcinwe ukuzinza okuhle kakhulu nokuthembeka ezindaweni ezahlukene.

INGXENYE.01 I-inverter yokugcina amandla

Indima ye-inverter ohlelweni lokugcina amandla ikakhulukazi ukuguqulwa kwamandla, ukulawula nokuxhumana, ukulawula amandla, njll. Isebenzisa kakhulu ama-capacitor anomthamo ophezulu wokusebenza, ukumelana kwamanje kwe-ripple ephezulu kanye nokumelana kwamandla aphezulu ukuze idlale indima yokuzinza nokuhlunga kwamandla, ukugcinwa nokukhululwa kwamandla, kanye nokushaya kwe-DC okubushelelezi.

Ama-capacitor e-YMIN anezici ezilandelayo ku-inverter:

Izinzuzo zobuningi obuphezulu:

Ekupheleni kokufakwayo kwe-micro-inverter, kuyadingeka ukuthola amandla kagesi akhiqizwa yidivayisi yamandla avuselelekayo. Lawa macala adinga ukuguqulwa yi-inverter ngesikhathi esifushane. Izici zama-capacitor e-YMIN anomthamo ophezulu zingathwala amacala amaningi ngevolumu efanayo, zimunce ingxenye yamandla kagesi, zithuthukise ukusebenza kahle kokuguqulwa, futhi zifeze ukuguqulwa kusuka ku-DC kuya ku-AC.

Ukumelana kwamanje okuphezulu kwe-ripple:

Uma i-inverter isebenza, amandla kagesi akhiqizwa ekugcineni kokukhipha kwawo angase abe nenani elikhulu lezingxenye ze-harmonic, okuzoba nomthelela omubi ekugcineni kokusetshenziswa kwegridi yamandla. Ama-capacitor esihlungi se-YMIN anganciphisa ngempumelelo okuqukethwe kwe-harmonic ekugcineni kokukhipha futhi ahlangabezane nesidingo somthwalo samandla e-AC asezingeni eliphezulu.

Izinzuzo ze-voltage ephezulu yokumelana:

Ngenxa ye-voltage engazinzile yokukhishwa kwe-photovoltaic, amadivayisi e-semiconductor yamandla ku-inverter azophinde akhiqize ama-voltage nama-current spikes ngesikhathi senqubo yokushintsha. Ama-capacitor e-YMIN anenzuzo ye-voltage ephezulu yokumelana, engamunca la ma-spikes, avikele amadivayisi kagesi, enze izinguquko ze-voltage kanye nezamanje zibe lula, anciphise ukulahlekelwa amandla, futhi athuthukise ukusebenza kahle kwe-inverter.

INGXENYE.02 Isiguquli Sesitoreji Samandla

Ohlelweni lokugcina amandla, lapho ibhethri kanye negridi kuhlangana, i-converter idinga ukwenza ukuguqulwa kwe-AC/DC ukuze iqedele ukugeleza kwamandla okuya ohlangothini lwesibili. Ngaphezu kwalokho, ingalawula usayizi wamanje futhi ilungise amandla. Ama-capacitor anganikeza ukuphuma kwe-voltage okuzinzile ku-converter, athuthukise i-power factor yesistimu, futhi andise ukusebenza kahle kanye nokuzinza kokusebenza kwe-converter.

Ama-capacitor e-YMIN anezici ezilandelayo ku-converter:

Imelana nomthelela wamandla aphezulu:

Ama-capacitor e-YMIN amunca umfutho ophezulu we-pulse okhiqizwa yi-converter kusukela ekugcineni kwe-DC-Link ukuze kufezwe ukulungiswa okunembile kwamandla okukhipha ukuze kuhlangatshezwane nezidingo zezimo ezahlukene. Ngokwakha isekethe yokushaja, igwema umthelela omkhulu ekuhlinzekweni kwamandla okufaka kanye nomthwalo ngesikhathi sokuqala okulula.

I-voltage ephezulu kakhulu yokumelana:

Izici ze-voltage ezimelana kakhulu nama-capacitor e-YMIN zingasetshenziswa njengezingxenye zokuvikela ukuvikela izingxenye ze-elekthronikhi ezizwelayo ekulimaleni lapho kukhiqizwa ama-voltage spikes ngesikhathi sokusebenza kwe-converter, ukuze i-converter yokugcina amandla ikwazi ukunikeza i-voltage eqinile kanye nokusekelwa kwemvamisa yegridi futhi iqinisekise ukusebenza okuzinzile kwesistimu.

Umthamo omkhulu:

Ama-capacitor e-YMIN angagcina amandla kagesi futhi anikeze amandla kagesi aqhubekayo ohlelweni lokuguqula lapho i-voltage yegridi ishintshashintsha kakhulu noma lapho amandla enqanyulwa, okuqinisekisa ukusebenza okuvamile kohlelo lokuguqula. Emithwalweni yokungenisa efana nama-motor, ama-capacitor anganikeza futhi isinxephezelo samandla asebenzayo, aqinise i-voltage, futhi athuthukise ukusebenza kokukhipha kwemoto.

INGXENYE.03 Uhlelo Lokuphathwa Kwebhethri

Uhlelo lokuphatha ibhethri luyidivayisi eqapha isimo samabhethri okugcina amandla. Lusetshenziswa kakhulu ukuphatha nokugcina iyunithi ngayinye yebhethri ngokuhlakanipha; ukuvimbela ibhethri ekushajeni ngokweqile nasekukhipheni ngokweqile, nokwandisa impilo yebhethri. I-capacitor idlala indima yokuhlunga, ukugcina amandla, ukulinganisa i-voltage kanye nokuqala ukuthamba ukuvimbela umthelela wamandla amaningi kwezinye izingxenye ze-elekthronikhi ngesikhathi sokuqalisa, nokwandisa impilo yesevisi yezingxenye.

Ama-capacitor e-YMIN anezici ezilandelayo ohlelweni lokuphatha ibhethri:

Amandla aqinile okumelana nomsinga omkhulu we-ripple:

Amasekethe ohlelweni lokuphatha ibhethri azokhiqiza izimpawu zomsindo zamaza ahlukahlukene. Ama-capacitor e-YMIN angahlunga le misindo futhi athuthukise ukuthembeka nokuzinza kwesistimu.

Ukumelana okunamandla kwe-overvoltage:

Ama-capacitor e-YMIN angaxhunywa ngokuhambisana kuzo zombili izinhlangothi zebhethri ngalinye. Ngezici zawo zokushaja nokukhipha, angavala amabhethri ngama-voltage aphezulu ukuze anciphise ama-voltage awo, futhi ashaje amabhethri ngama-voltage aphansi ukuze andise ama-voltage awo, ngaleyo ndlela afinyelele ibhalansi yama-voltage phakathi kwamabhethri asephaketheni lebhethri.

Umthamo omkhulu:

Uma umthwalo ohlelweni lokuphatha ibhethri udinga ugesi omkhulu ngokushesha, ama-capacitor e-YMIN angakhipha amandla agciniwe ngokushesha ukuze ahlangabezane nezidingo ezisheshayo zomthwalo. Angasetshenziswa njengesekethe yokuvikela ukunikeza ukwesekwa kwamandla kwesikhashana kwamasekethe ayisihluthulelo, ukuqinisekisa ukuthi isekethe yokuvikela ingasebenza kahle, futhi inqamule ukuxhumana phakathi kwebhethri nomthwalo ngesikhathi.
