Amandla okugcina amandla
Izinhlelo zokugcina amandla ziyingxenye ebalulekile yezinhlelo zamandla zanamuhla zanamuhla. Zisetshenziswa kabanzi njengoba zinciphisa imfucuza yamandla futhi zithuthukise ukusebenza kahle kwezinhlelo zamandla. Ngenxa yokuxhumana phakathi kwamabhethri kanye negridi yamandla, abaguquli kudingeka ukuthi benze ukuguqulwa kwe-AC-DC futhi banikeze amandla ukugeleza kwamandla kwe-bitirectional. Ngaphezu kwalokho, abaguquli badlale indima ebalulekile ezinhlelweni zokugcina amandla ngokulawula amandla ngokulawula ubukhulu kanye nokuqondisa okuphezulu okuphezulu kanye nokunikeza ukubekezelela okuphezulu kakhulu kanye nokuhlinzeka ngokulayishwa ngokweqile ukuze kuqinisekiswe ukuphepha kohlelo.
Phakathi komjikelezo we-rexifier kanye ne-Converter Circuit, aI-DC-Link Capacitoriyadingeka ekusekelweni kwamanje nokuhlunga. Umsebenzi wayo oyinhloko ukudonsa ama-Pulse aphezulu ebhasini le-DC-Link, ukuvikela i-Pulse Voltage ephezulu ukuthi ikhiqizwe ekulweni kwe-DC-Link. Lokhu kuvikela nomthwalo ukuphela komthelela wokuqunjelwa ngokweqile.
Ama-apacitors we-YMin anezici ezilandelayo enkundleni yokuguqula
01. Amandla aphezulu
I-Copacitor ye-DC-Link Capacitor igcina amandla kagesi, ivumela ukuthi inikeze amandla aqhubekayo ohlelweni lokuguqula ngokushintshashintsha kwamandla kagesi noma ukuphuma kwamandla, ukuqinisekisa ukusebenza okujwayelekile kohlelo. Ngokwengeziwe, lapho uhlelo lokuguqula ludinga inani elikhulu lamandla, i-DC-Link Capacitor ingakhipha ngokushesha amandla agcinwe ukuze ahlangabezane nezidingo zesikhashana. Emithanjeni ebabazekayo efana nama-motors, i-capacitor ibuye futhi inikeze isinxephezelo samandla asebenzayo, izinzile ezinamandla, futhi ithuthukise ukusebenza kwezimoto. Lokhu kudlala indima ebalulekile ekuthuthukiseni ukusebenza kahle kohlelo nokuqina.
02. Ukumelana ne-Ultra-High
Ama-capacitors we-YMin, ngokumelana nawo wonke ama-voltage amelana nawo aphezulu, angasebenza njengezakhi ezivikelayo. Ngesikhathi sokusebenza kokuguqulwa, bavikeleke izingxenye ezibucayi ze-elekthronikhi emonakalweni odalwe yi-voltage spikes. Lokhu kunika amandla abaguquli be-Energy Storactive ukuthi bahlinzeke ngokuxhaswa kwamandla okuzinzile kanye nokuxhaswa kwegridi yamandla, kuqinisekisa ukusebenza okuthembekile kohlelo.
03. Ukuphikiswa okuphezulu kwamanje kokuhlinzwa
Ama-capacitors we-ymin athola ngempumelelo imisinga ephakeme ye-pulse ekhiqizwa isiguquli endaweni yokusebenza kwe-DC-Link, enika amandla ukulawulwa kwamandla okukhishwa okuqondile ngokulawulwa kwamanje. Lokhu kuqinisekisa ukuthi iConverter ihlangabezana nezidingo zezimo ezahlukahlukene futhi ziletha umphumela wekhwalithi ephezulu ye-AC. Ngesikhathi senqubo yokuqalisa okuthambile, ama-capacitors we-YMIn akhetha ingxenye yesifunda sokushaja, esiza ukuvikela umthelela owedlulele ekunikezelweni kwamandla okufaka kanye nomthwalo.
04. Impilo ende
Ama-capacitors we-YMin, akhiqizwa ngezinqubo ezijwayelekile futhi ahlolwe ngokuhlolwa okuqinile kokulethwa kwangaphambili, afaka nobuningi obuphezulu nokuphikiswa okuhle kwamanje. Lezi zimfanelo zinika amandla abaguquli ezinhlelweni zokugcina amandla ukuba basebenze ngokumangalisa izikhathi ezengeziwe, benciphisa ukwehluleka kanye nezindleko zokugcina.
