Chitsimikizo chodalirika cha OBC, nsanja yamagetsi amphamvu kwambiri yamagalimoto atsopano: Mayankho osiyanasiyana a YMIN a capacitor apamwamba

Pamene magalimoto atsopano amphamvu akufulumizitsa kusintha kwawo kukhala mphamvu yochaja mwachangu, kuyatsa ndi kutulutsa magetsi mbali zonse ziwiri, komanso kuphatikiza kwakukulu, ukadaulo wa OBC womwe uli mkati mwake ukukwera - makina amagetsi a 800V okwera mphamvu akukulirakulira ku makina a 1200V, ndipo kapangidwe ka nsanja yamagetsi okwera mphamvu kamakhala maziko a kuyatsa mwachangu.

01 Kodi capacitor imagwira ntchito yofunika bwanji mu OBC yomwe ili mkati?

Mu dongosolo la batri lamphamvu kwambiri, capacitor ndiye "malo osungira mphamvu ndi kusefera" a OBC & DCDC, ndipo magwiridwe ake amatsimikiza mwachindunji magwiridwe antchito, kuchuluka kwa mphamvu ndi kudalirika kwa dongosololi - kaya ndi kukhudza nthawi yomweyo kwa nsanja yamphamvu kwambiri, kusinthasintha kwa mphamvu yama frequency apamwamba, kapena mikhalidwe yovuta yogwirira ntchito yamagetsi a mbali zonse ziwiri, capacitor imafunika kuti igwire ntchito bwino pansi pa malo amagetsi amphamvu kwambiri, ma frequency apamwamba, komanso kutentha kwambiri. Chifukwa chake, kusankha ma capacitor amphamvu komanso osasunthika komanso osasunthika ndi chinthu chofunikira kwambiri pakutsimikiza magwiridwe antchito a OBC omwe ali m'bwalo.

02 Kodi ubwino wa YMIN capacitors ndi wotani pakugwiritsa ntchito?

Pofuna kuthana ndi zofunikira zolimba za OBC & DCDC pansi pa machitidwe amphamvu kwambiri kuti ma capacitor athe kupirira magetsi amphamvu, kukula kochepa, moyo wautali, komanso mphamvu yamagetsi yothamanga kwambiri, YMIN yakhazikitsa matrix ya zinthu zamagetsi zogwira ntchito bwino kuti ipatse mphamvu makina a OBC & DCDC a magalimoto atsopano amphamvu.

01Capacitor ya electrolytic ya aluminiyamu yamadzimadzi yokhala ndi nyanga: "choteteza chokhazikika cha magetsi" pazochitika zamphamvu kwambiri

· Voliyumu yolimba kwambiri: Poyankha mavuto a kusinthasintha kwa magetsi ndi kukwera kwa magetsi komwe kumakumana nako nthawi zambiri mu OBC, capacitor ya CW3H series horn ili ndi kapangidwe kokwanira ka voltage kuti ipereke chithandizo cha voltage yolimba komanso chitetezo cha overvoltage. Imayesedwa mwamphamvu kuti ikule bwino komanso kuti ikhale yolimba isanachoke ku fakitale kuti itsimikizire kuti imakhala yokhazikika kwa nthawi yayitali komanso yodalirika mu ntchito za OBC.

· Kukana kwamphamvu kwa ripple current: OBC ikugwira ntchito, surge current imapangidwa chifukwa cha kusintha kwa mphamvu pafupipafupi. Pamene liquid horn-type aluminiyamu electrolytic capacitor ikugwiritsidwa ntchito ndi ripple current yoyesedwa ka 1.3, kutentha kumakhala kokhazikika ndipo magwiridwe antchito a chinthucho amakhala okhazikika.

· Kuchuluka kwa mphamvu: Njira yapadera yozungulira riveting imawongolera mphamvu yamagetsi. Mphamvu yake ndi yokwera ndi 20% kuposa makampani omwe ali ndi mphamvu yomweyo. Ndi mphamvu yamagetsi ndi mphamvu yomweyo, kampani yathu ndi yaying'ono kukula, kusunga malo oyika ndikukwaniritsa kuchepa kwa makina onse.

02Chojambulira cha electrolytic cha aluminiyamu cholumikizira madzi: "Kupambana kwabwino" kutentha kwambiri komanso malo ochepa

Makina a LKD a aluminiyamu opangidwa ndi electrolytic capacitor amatha kugwiritsidwa ntchito kuti agwirizane ndi yankho lomwe silingagwiritse ntchito ma capacitor a horn chifukwa cha kuchepa kwa voliyumu. Ndi chisankho chabwino kwambiri pakusefa bwino komanso kusungira mphamvu kodalirika kwa OBC yoyikidwa m'galimoto m'malo okhala ndi magetsi ambiri, ma frequency ambiri komanso ovuta.

· Kukana kutentha kwambiri: Kufikira kutentha kwa ntchito kwa 105℃ mu phukusi laling'ono, kupitirira kwambiri ma capacitor wamba okhala ndi kukana kutentha kwa 85℃, kupereka chitetezo chodalirika ku malo omwe amagwiritsidwa ntchito kutentha kwambiri.

· Kuchuluka kwa mphamvu: Pansi pa mphamvu yomweyo, mphamvu yomweyo ndi zofunikira zomwezo, m'mimba mwake ndi kutalika kwa mndandanda wa LKD ndizochepa ndi 20% kuposa za zinthu za nyanga, ndipo kutalika kwake kungakhale kocheperako ndi 40%.

· Kugwira ntchito bwino kwambiri kwamagetsi ndi kutseka: Chifukwa cha kapangidwe kake koteteza kutentha kwambiri, ESR yachepa kwambiri, ndipo ili ndi mphamvu yolimba yolimbana ndi ma ripple current. Zipangizo zapadera zotsekera ndi ukadaulo zimapangitsa kuti mpweya wa LKD ukhale wabwino kuposa capacitor ya horn, pomwe imakulitsa moyo wautumiki, womwe ungakwaniritse zofunikira za maola 105℃ 12000.

03 Capacitor yosakanikirana ndi madzi olimba: "mlatho wa njira ziwiri" pakati pa kugwira ntchito bwino komanso kukhazikika

· Kuchuluka kwa capacitance: Poyerekeza ndi ma capacitor a voliyumu yomweyo pamsika, capacitance yaMa capacitor osakanizidwa a YMIN olimba-madzimadziimawonjezeka ndi zoposa 30%, ndipo mphamvu ya capacitance imakhala yokhazikika mkati mwa ±5% mu kutentha kwakukulu. Pambuyo pa kugwira ntchito kwa nthawi yayitali, mphamvu ya capacitance imakhala yokhazikika pa zoposa 90%.

· Mphamvu yotsika kwambiri yotulutsa madzi ndi ESR yotsika: Mphamvu yotuluka madzi imatha kuyendetsedwa mkati mwa 20μA, ndipo ESR imatha kuyendetsedwa mkati mwa 8mΩ, ndipo kusinthasintha kwa ziwirizi ndi kwabwino. Ngakhale pambuyo pa njira yosungunula madzi ndi kutentha kwa 260℃, ESR ndi mphamvu yotuluka madzi zimakhalabe zokhazikika.

04 Ma capacitor a mafilimu: "chotchinga chitetezo" cha moyo wautali komanso chodalirika kwambiri

Poyerekeza ndi ma capacitor a electrolytic, ubwino wa ma capacitor a filimu umaonekera mu mphamvu yamagetsi yolimba, ESR yotsika, kusakhala ndi polarity, kugwira ntchito kokhazikika, komanso moyo wautali, zomwe zimapangitsa kuti kapangidwe kake ka makina ogwiritsira ntchito kakhale kosavuta, kukana ma ripple, komanso kudalirika kwambiri m'malo ovuta.

· Volti yolimba kwambiri: kupirira kwa voltage yokwera kwambiri yoposa 1200V, palibe chifukwa cholumikizira zingapo, ndipo imatha kupirira voliyumu yogwira ntchito yoyesedwa nthawi 1.5.

· Mphamvu ya ripple yapamwamba kwambiri: Kulekerera ripple kwa 3μF/A kuli kopitilira nthawi 50 kuposa ma capacitor achikhalidwe a electrolytic.

· Chitsimikizo cha moyo wonse: maola opitilira 100,000 a moyo wautumiki, mtundu wouma komanso nthawi yopuma yopanda zinthu. Pansi pa mikhalidwe yomweyi yogwiritsira ntchito,ma capacitor a filimuakhoza kusunga magwiridwe antchito awo kwa nthawi yayitali.

Mtsogolomu, YMIN ipitiliza kufufuza mozama za ukadaulo wamagetsi amphamvu komanso wophatikizika kuti ipereke mphamvu yogwira ntchito bwino komanso yodalirika pamakina a OBC & DCDC a magalimoto atsopano amphamvu!
