IiPCS zokuGcina amandla
Iinkqubo zokugcina amandla yinxalenye ebalulekileyo yeenkqubo zala maxesha zamandla ahlaziyekayo. Zisetyenziswa ngokubanzi njengoko zinciphisa ngokusebenzayo inkcitho yamandla kunye nokuphucula ukusebenza kakuhle kweenkqubo zamandla. Ngenxa yokusebenzisana phakathi kweebhetri kunye negridi yamandla, abaguquli bayafuneka ukuba benze ukuguqulwa kwe-AC-DC kunye nokuvumela ukuhamba kwamandla okuphindwe kabini. Ukongezelela, abaguquli badlala indima ebalulekileyo kwiinkqubo zokugcina amandla ngokulawula amandla ngokulawula ubukhulu kunye nolwalathiso lwangoku, okwenza ukuba i-peak shaving kunye nokuzaliswa kwentlambo kuphuculwe ukusebenza kakuhle kokusetyenziswa kwamandla, kunye nokubonelela ngokhuseleko lomthwalo ogqithisiweyo ukuqinisekisa ukhuseleko lwenkqubo.
Phakathi kwesekethe yokuhlaziya kunye nesekethe yokuguqula, aI-DC-LINK capacitoriyafuneka kwinkxaso yangoku kunye nokucoca. Umsebenzi wayo ophambili kukufunxa i-high pulse current kwi-DC-LINK ibhasi, ukuthintela i-high pulse voltage ukuba iveliswe kwi-impedance ye-DC-LINK. Oku kukwakhusela ukuphela komthwalo kwimpembelelo yokugqithisa.
I-YMIN capacitors inezi mpawu zilandelayo kwintsimi yokuguqula
01. Umthamo ophezulu
I-DC-Link capacitor igcina amandla ombane, iyenza ibonelele ngamandla aqhubekayo kwisixokelelwano soguqulo ngexesha lokuguquguquka okukhulu kwamandla ombane wegridi okanye ukuphuma kombane, ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo. Ukongezelela, xa inkqubo yokuguqula ifuna umthamo omkhulu wamandla, i-DC-Link capacitor inokukhulula ngokukhawuleza amandla agciniweyo ukuhlangabezana neemfuno zexeshana. Kwimithwalo ye-inductive efana neenjini, i-capacitor ikwabonelela ngembuyekezo yamandla asebenzayo, izinzile i-voltage, kunye nokuphucula ukusebenza kweemoto. Oku kudlala indima ebalulekileyo ekwandiseni impumelelo nozinzo lwenkqubo.
02. Ukumelana ne-Ultra-High Voltage
I-YMIN capacitors, kunye ne-ultra-high-high-voltage resistant, inokusebenza njengezinto ezikhuselayo. Ngexesha lokusebenza kwesiguquli, zikhusela izinto ze-elektroniki ezinobuthathaka kumonakalo owenziwe zizipikhi zombane. Oku kwenza ukuba abaguquli bokugcina amandla banike amandla ombane ozinzileyo kunye nenkxaso yefrikhwensi kwigridi yamandla, ukuqinisekisa ukusebenza okuthembekileyo kwenkqubo.
03. Ukunyangwa okuPhakamileyo kwangoku kweSurge
I-YMIN capacitors ithatha ngokufanelekileyo i-pulse currents ephezulu eyenziwa ngumguquli ekupheleni kwe-DC-Link, eyenza ukulawulwa kwamandla okuphuma okuchanekileyo ngolawulo lwangoku. Oku kuqinisekisa ukuba umguquli uhlangabezana neemfuno zeemeko ezahlukeneyo kwaye unikezela ngemveliso ye-AC ephezulu. Ngethuba lenkqubo yokuqalisa i-soft-start of converters, i-YMIN capacitors iyingxenye yesiphaluka sokutshaja, inceda ukukhusela impembelelo egqithisileyo kwigalelo lombane kunye nomthwalo.
04. Ubomi obude
I-YMIN capacitors, eyenziwe ngeenkqubo ezisemgangathweni kwaye iphantsi kovavanyo oluqatha lwangaphambi kokuhanjiswa, ibonakalisa ukuxinana okuphezulu kunye nokumelana nokuqhambuka kwangoku. Ezi mpawu zenza ukuba abaguquli kwiinkqubo zokugcina amandla basebenze ngokuzinzileyo kwixesha elongeziweyo, ukunciphisa ukusilela kunye neendleko zokugcina.
