Ma capacitor a Fyuluta ndi DC-link ndi zinthu zofunika kwambiri pakusintha mphamvu

Kufotokozera Kwachidule:

Ma capacitor a polypropylene okhala ndi kristalo wogawanika kwambiri ndi omwe amasankhidwa kwambiri pa zinthu zambiri monga DC Fyuluta, kusungira mphamvu ndi zina zofanana m'zaka za m'ma 2000.

Mbali

1. PP Box-type, dry resin infusion;
2. Mtedza wa mkuwa/ma screw leads, malo osungira chivundikiro cha pulasitiki, kuyika kosavuta;
3. Kuchuluka kwakukulu, kukula kochepa;
4. Kukana mphamvu yamagetsi yapamwamba, ndi kudzichiritsa yokha;
5. Mphamvu yamagetsi yothamanga kwambiri, mphamvu yamagetsi yothamanga kwambiri yothamanga kwambiri (dv/dt).
Monga zinthu zina za CRE, ma capacitor otsatizana ali ndi satifiketi ya UL ndipo amayesedwa 100% kuti atenthedwe.

Kugwiritsa ntchito

1. Amagwiritsidwa ntchito kwambiri mu DC-Link circuit posefa malo osungira mphamvu;
2. Ikhoza kusintha ma capacitor a electrolytic, kugwira ntchito bwino komanso kukhala ndi moyo wautali.
3. Inverter ya Pv, chosinthira mphamvu ya mphepo; Mitundu yonse ya magetsi osinthira pafupipafupi ndi inverter; Magalimoto amagetsi ndi a hybrid; SVG, zida za SVC ndi mitundu ina ya kasamalidwe kabwino ka mphamvu.

Chiyembekezo cha moyo

Chojambula cha mzere

Kufunika kwa kusunga mphamvu komanso magwero obwezerezedwanso kumalimbikitsa kupanga zinthu monga magalimoto amagetsi, ma PV converters, ma jenereta amagetsi amphepo. Zinthuzi zimafuna DC kuchokera ku AC inverter kuti zigwire ntchito. Ma filter ndi ma DC-link capacitors ndi zinthu zofunika kwambiri pamakina amagetsi zomwe zimathandiza pakufunikira mphamvu yowonjezera ndi ma voltage ambiri ndi ma ripple currents.

Monga kampani yatsopano yaukadaulo wapamwamba, CRE ili ndi gulu lotsogola la R&D ndi kupanga ma capacitor amagetsi amagetsi, ndipo yakhazikitsa malo opangira mainjiniya a R&D amagetsi amagetsi ndi mabungwe odziwika padziko lonse lapansi ofufuza. Pakadali pano, CRE ili ndi zopanga zoposa 40 ndi ma patent amitundu yofunikira ndipo yatenga nawo gawo pakupanga miyezo 10 yadziko lonse komanso yamakampani, yotsimikiziridwa ndi ISO-9001, IATF16949, ISO14001/45001, ndi UL. Tidzipereka kupanga mabizinesi ambiri kuti tiyendetse patsogolo luso lamagetsi.

Zinthu zodziwika bwino za CRE:
① DC-link capacitor
② chojambulira cha AC
③ Kusungira mphamvu / Pulse capacitor
④ Wonyoza IGBT
⑤ Kachipangizo kolumikizirana
⑥ Kaputeni woziziritsidwa ndi madzi

Yapitayi: Kachipangizo ka Filimu Kapadera ka zamagetsi
