Ama-PCS Okugcina Amandla
Izinhlelo zokugcina amandla ziyisici esibalulekile sezinhlelo zamandla avuselelekayo zanamuhla. Zisetshenziswa kabanzi njengoba zinciphisa ngempumelelo imfucuza yamandla futhi zithuthukisa ukusebenza kahle kwezinhlelo zamandla. Ngenxa yokusebenzisana phakathi kwamabhethri negridi yamandla, abaguquli bayadingeka ukwenza ukuguqulwa kwe-AC-DC futhi bavumele ukugeleza kwamandla okuya ohlangothini lwesibili. Ngaphezu kwalokho, abaguquli badlala indima ebalulekile ezinhlelweni zokugcina amandla ngokulawula amandla ngokulawula ubukhulu kanye nesiqondiso samandla kagesi, okuvumela ukushefa okuphezulu kanye nokugcwaliswa kwesigodi ukuthuthukisa ukusebenza kahle kokusetshenziswa kwamandla, kanye nokunikeza ukuvikelwa kokulayisha ngokweqile ukuqinisekisa ukuphepha kwesistimu.
Phakathi kwesekethe yokulungisa kanye nesekethe yokuguqula,I-capacitor ye-DC-LINKiyadingeka ekusekelweni nasekuhlungeni kwamanje. Umsebenzi wayo oyinhloko ukumunca ugesi ophezulu we-pulse ebhasini le-DC-LINK, ukuvimbela ugesi ophezulu we-pulse ukuthi ukhiqizwe ku-impedance ye-DC-LINK. Lokhu kuvikela nomkhawulo womthwalo emthelela we-overvoltage.
Ama-capacitor e-YMIN anezici ezilandelayo ensimini yokuguqula
01. Amandla Aphezulu
I-DC-Link capacitor igcina amandla kagesi, okwenza ikwazi ukunikeza amandla aqhubekayo ohlelweni lokuguqula ngesikhathi sokushintshashintsha okukhulu kwamandla kagesi noma ukucima kukagesi, okuqinisekisa ukusebenza okuvamile kohlelo. Ngaphezu kwalokho, lapho uhlelo lokuguqula ludinga amandla amaningi, i-DC-Link capacitor ingakhipha amandla agciniwe ngokushesha ukuze ihlangabezane nezidingo zesikhashana. Emithwalweni yokungenisa amandla efana nama-motor, i-capacitor iphinde inikeze isinxephezelo samandla asabelayo, izinzise amandla kagesi, futhi ithuthukise ukusebenza kwe-motor. Lokhu kudlala indima ebalulekile ekuthuthukiseni ukusebenza kahle kohlelo kanye nokuzinza.
02. Ukumelana Ne-Ultra-High Voltage
Ama-capacitor e-YMIN, anokumelana kwawo namandla aphezulu kakhulu, angasebenza njengezingxenye ezivikelayo. Ngesikhathi sokusebenza kwe-converter, avikela izingxenye ze-elekthronikhi ezizwelayo emonakalweni obangelwa ukukhuphuka kwamandla. Lokhu kwenza abaguquli besitoreji samandla bakwazi ukunikeza amandla aqinile kanye nokusekelwa kwemvamisa kugridi yamandla, okuqinisekisa ukusebenza okuthembekile kwesistimu.
03. Ukumelana Nokwanda Kwamanje Okuphezulu
Ama-capacitor e-YMIN amunca ngempumelelo ama-pulse currents aphezulu akhiqizwa yi-converter ekugcineni kwe-DC-Link, okwenza kube nokulawulwa okunembile kwamandla okukhipha ngokulawula kwamanje. Lokhu kuqinisekisa ukuthi i-converter ihlangabezana nezidingo zezimo ezahlukahlukene futhi iletha umphumela we-AC osezingeni eliphezulu. Ngesikhathi senqubo yokuqalisa kancane yama-converter, ama-capacitor e-YMIN akha ingxenye yesekethe yokushaja, esiza ukuvimbela umthelela omkhulu ekunikezelweni kwamandla okufaka kanye nomthwalo.
04. Impilo Ende
Ama-capacitor e-YMIN, akhiqizwa ngezinqubo ezijwayelekile futhi ahlolwe ngaphambi kokulethwa ngokuqinile, anezici eziphakeme kakhulu zokuqina kanye nokumelana okuhle kakhulu nokukhuphuka kwamandla kagesi. Lezi zimfanelo zivumela abaguquli ezinhlelweni zokugcina amandla ukuthi basebenze ngokuzinzile isikhathi eside, okunciphisa ukwehluleka kanye nezindleko zokulungisa.
