Ukujova ubungqabavu obusha kuziguquli zokugcina amandla futhi kuholele ekuguqukeni kokusebenza kahle kwamandla: Ukusetshenziswa kwama-capacitor e-YMIN

I-Energy Storage PCS

Amasistimu okugcina amandla ayingxenye ebalulekile yesistimu yamandla avuselelekayo yesimanje. Zisetshenziswa kabanzi njengoba zinciphisa ngempumelelo ukumoshwa kwamandla futhi zithuthukisa ukusebenza kahle okuphelele kwezinhlelo zamandla. Ngenxa yokusebenzisana phakathi kwamabhethri negridi yamandla, iziguquli ziyadingeka ukuze zenze ukuguqulwa kwe-AC-DC futhi zinike amandla ukugeleza kwamandla aqondiswa kabili. Ukwengeza, iziguquli zidlala indima ebalulekile ezinhlelweni zokugcina amandla ngokulawula amandla ngokulawula ubukhulu nesiqondiso samanje, okwenza ukushefa okuphezulu nokugcwaliswa kwesigodi ukuze kuthuthukiswe ukusebenza kahle kokusetshenziswa kwamandla, kanye nokuhlinzeka ngokuvikelwa kokugcwala ngokweqile ukuze kuqinisekiswe ukuphepha kwesistimu.

Phakathi kwesekethe yokulungisa kabusha kanye nesekethe yokuguqula, aI-DC-LINK capacitoriyadingeka ekusekeleni kwamanje nokuhlunga. Umsebenzi wayo oyinhloko ukumunca i-pulse current ephezulu ebhasini le-DC-LINK, ukuvimbela amandla kagesi aphezulu ukuthi angakhiqizi ekuvinjweni kwe-DC-LINK. Lokhu futhi kuvikela ukuphela komthwalo kumthelela wokugcwala ngokweqile.

Ama-capacitor e-YMIN anezici ezilandelayo kunkambu yesiguquli

01. Ikhono Eliphezulu

I-DC-Link capacitor igcina amandla kagesi, iyenza ikwazi ukunikeza amandla aqhubekayo kusistimu yesiguquli ngesikhathi sokuguquguquka okukhulu kwamandla kagesi wegridi noma ukuphela kukagesi, okuqinisekisa ukusebenza okuvamile kwesistimu. Ukwengeza, lapho uhlelo lokuguqula ludinga inani elikhulu lamandla, i-DC-Link capacitor ingakhulula ngokushesha amandla agciniwe ukuze ihlangabezane nezidingo zesikhashana. Emithwalweni ye-inductive efana nama-motor, i-capacitor iphinde inikeze isinxephezelo samandla asebenzayo, igxilise i-voltage, futhi ithuthukise ukusebenza kwemoto. Lokhu kudlala indima ebalulekile ekuthuthukiseni ukusebenza kahle kwesistimu nokuzinza.

02. I-Ultra-High Voltage Resistance

Ama-capacitor e-YMIN, anokumelana kwawo ne-ultra-high voltage, angasebenza njengezingxenye zokuvikela. Ngesikhathi sokusebenza kokuguqula, bavikela izingxenye ze-elekthronikhi ezibucayi emonakalweni obangelwa ama-voltage spikes. Lokhu kwenza iziguquli zokugcina amandla zinikeze ukusekelwa okuzinzile kwe-voltage nefrikhwensi kugridi yamandla, ukuqinisekisa ukusebenza okuthembekile kwesistimu.

03. Ukumelana Nokwanda Kwamanje Kokukhuphuka

Ama-capacitor e-YMIN amunca ngempumelelo ama-pulse currents aphezulu akhiqizwa isiguquli ekugcineni kwe-DC-Link, evumela ukulawulwa kwamandla okukhiphayo okunembile ngokulawula kwamanje. Lokhu kuqinisekisa ukuthi isiguquli sihlangabezana nezidingo zezimo ezahlukahlukene futhi iletha okukhiphayo kwekhwalithi ephezulu kwe-AC. Phakathi nenqubo yokuqalisa ethambile yeziguquli, ama-capacitor e-YMIN ayingxenye yesekethe yokushaja, esiza ukuvimbela umthelela omkhulu ekunikezeni amandla okokufaka nokulayisha.

04. Impilo ende

Ama-capacitor e-YMIN, akhiqizwa ngezinqubo ezijwayelekile futhi angaphansi kokuhlolwa okuqinile kwangaphambi kokulethwa, afaka ukuminyana okuphezulu kanye nokumelana nokuhlinzwa kwamanje okuhle kakhulu. Lezi zimfanelo zivumela iziguquli ezinhlelweni zokugcina amandla ukuthi zisebenze ngokuzinzile phakathi nezikhathi ezinwetshiwe, zehlise ukwehluleka kanye nezindleko zokunakekela.
