Zosefera ndi ma capacitor a DC-link ndizofunikira kwambiri pamagetsi osinthira mphamvu

Zosefera ndi DC-link capacitors ndi zigawo zikuluzikulu kungokhala chete kwa mphamvu kutembenuka dongosolo Featured Image

Kufotokozera Kwachidule:

Ma crystalline segmented metallized polypropylene capacitors ndi gawo lazosankha zambiri Zosefera za DC, kusungirako mphamvu ndi ntchito zofananira zazaka za 21st.

Mbali

1. PP Bokosi-mtundu, youma utomoni kulowetsedwa;
2. Copper nut / screw lead, insulated pulasitiki chivundikiro malo, unsembe mosavuta;
3. Kukhoza kwakukulu, kukula kochepa;
4. Kukana mphamvu yamagetsi, ndi kudzichiritsa;
5. High ripple current, mkulu dv / dt kupirira mphamvu.
Monga zinthu zina za CRE, mndandanda wa capacitor uli ndi satifiketi ya UL ndi 100% yoyesedwa yoyaka.

Kugwiritsa ntchito

1. Amagwiritsidwa ntchito kwambiri mudera la DC-Link posefera kusungirako mphamvu;
2. Ikhoza kusintha ma electrolytic capacitors, ntchito yabwino komanso moyo wautali.
3. Pv inverter, wind power converter; Mitundu yonse ya ma frequency converter ndi inverter magetsi;Magalimoto oyera amagetsi ndi osakanizidwa;SVG,zipangizo za SVC ndi mitundu ina ya kasamalidwe ka mphamvu zamagetsi.

Chiyembekezo cha moyo

Kujambula autilaini

Kufunika kopulumutsa mphamvu ndi magwero ongowonjezwdwa kumalimbikitsa chitukuko cha zinthu monga magalimoto amagetsi, otembenuza a PV, ma jenereta amagetsi amphepo.Zogulitsazi zimafunikira DC kupita ku AC inverter kuti izindikire makina ogwiritsira ntchito.Zosefera ndi ma capacitor a DC-link ndi zinthu zofunika kwambiri zomwe sizimangokhala pamagetsi omwe amapereka chithandizo chofunikira chowonjezera mphamvu ndi ma voliyumu apamwamba komanso mafunde othamanga.

Monga bizinesi yotukuka yaukadaulo wapamwamba, CRE ili ndi R&D yakutsogolo ndi gulu lopanga zida zamagetsi zamagetsi zamagetsi, ndikukhazikitsa malo opangira zida zamagetsi za R&D ndi mabungwe ofufuza odziwika padziko lonse lapansi.Pakadali pano, CRE ili ndi zopanga zopitilira 40 ndi zovomerezeka zachitsanzo zofunikira ndipo idatenga nawo gawo pakukulitsa miyezo 10 yamayiko ndi mafakitale, yotsimikiziridwa ndi ISO-9001, IATF16949, ISO14001/45001, ndi UL.Timadzipereka kupanga mabizinesi ambiri kuti tiyendetse luso lamagetsi.

CRE zotchuka:
① DC-link capacitor
② AC fyuluta capacitor
③ Kusungirako mphamvu / Pulse capacitor
④ IGBT snubber
⑤ Resonance capacitor
⑥ Madzi utakhazikika capacitor
