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, zida 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 yomwe ikubwera yaukadaulo wapamwamba, CRE ili ndi gulu lakutsogolo la R&D ndi gulu lopanga ma capacitor amagetsi amagetsi, ndikukhazikitsa malo opangira uinjiniya wamagetsi a R&D okhala 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
