Kutulutsidwa kwa Gulu | Wuxi, China | Juni 10, 2020

Kachipangizo ka filimu kopangidwa ndi DMJ-MC ku CRE kali ndi ubwino wopikisana kuposa kachipangizo ka electrolytic kachikhalidwe mu ma frequency converters ndi ma inverters chifukwa cha kukula kwake kochepa, kuchuluka kwa mphamvu, kukana mphamvu zambiri, kukhala ndi moyo wautali, mtengo wotsika wopanga komanso kuthekera kodzichiritsa.

 

Wuxi, Jiangsu (June 10, 2020) – Wuxi CRE New Energy yakhala ikugwira ntchito yopanga ma capacitor a filimu yachitsulo kuyambira 2011. Yogwiritsidwa ntchito kwambiri mu DC-Link circuit posefera ndi kusunga mphamvu, mndandanda wa DMJ-MC umayimira ma capacitor osiyanasiyana a filimu yachitsulo ku CRE.

 

Ndi mphamvu yamagetsi yochokera pa 450 mpaka 4000 VDC ndi mphamvu yamagetsi kuyambira 50-4000 UF, capacitor ya DMJ-MC ili ndi mtedza wamkuwa ndi chivundikiro cha pulasitiki chotetezera kutentha. Imapakidwa mu silinda ya aluminiyamu ndipo imadzazidwa ndi utomoni wouma. Mphamvu yamagetsi yokulirapo yocheperako, capacitor ya DMJ-MC ikhoza kuyikidwa mosavuta.

 

Mndandanda wa DMJ-MC, pamodzi ndi ma capacitor ena a filimu opangidwa ndi zitsulo ku CRE, umapereka magwiridwe antchito abwino kwambiri mu ma frequency converters ndi ma inverters poyerekeza ndi ma capacitor achikhalidwe a electrolytic ndipo ukulowa m'malo mwa mpikisano wogwiritsa ntchito wachiwiri.

 

Kapangidwe ka dielectric ka aluminiyamu oxide ndi mphamvu ya electrolyte zimachepetsa mphamvu yamagetsi yochulukirapo ya capacitor ya electrolytic. Capacitor yachikhalidwe ya electrolytic nthawi zambiri imakhala ndi mphamvu yamagetsi yokwana 500V kapena 600V. Pakufunika mphamvu yamagetsi yochulukirapo, ma capacitor angapo a electrolytic ayenera kulumikizidwa motsatizana pamodzi ndi mphamvu yoyenera kuti magetsi azitha kusinthasintha. Izi zidzawonjezera kusakhazikika kwa ma capacitor ndipo mwina zingayambitse kuphulika kapena kutuluka kwa electrolyte, zomwe zimawononga chilengedwe.

 

Komabe, mndandanda wa DMJ-MC, monga capacitor yamafilimu yachitsulo ku CRE, umapereka mayankho ku zofooka zonse ndi zovuta za ma capacitor achikhalidwe a electrolytic omwe atchulidwa pamwambapa. Choyamba, sigwiritsa ntchito ma electrolyte a mankhwala konse zomwe zikutanthauza kuti ndi yotetezeka kwambiri ku chilengedwe. Komanso, imapereka kukana kwa voltage yayikulu pa capacitor iliyonse yokhala ndi voltage yovomerezeka kuyambira 450 mpaka 4000 VDC. Kukana kwa voltage yayikulu kwambiri kumakhala kokwera pafupifupi nthawi 7 kuposa kwa capacitor yachikhalidwe ya electrolytic. Kupatula apo, ili ndi kukula kocheperako, kulemera kopepuka komanso kuchuluka kwa mphamvu komwe kumabweretsa mtengo wotsika wopanga.

 

Kuphatikiza apo, DMJ-MC metalized film capacitor ili ndi mawonekedwe odzichiritsa yokha, mphamvu yoletsa kulephera kwakukulu pakachitika vuto lamkati. Filimu ya dielectric mu DMJ-MC imakutidwa ndi wosanjikiza woonda wachitsulo. Pakakhala malo ofooka kapena kusayera pa dielectric, kuwonongeka kudzachitika. Mphamvu yomwe imatulutsidwa ndi arc discharge panthawi yosweka idzakhala yokwanira kuwononga wosanjikiza wachitsulo wozungulira, kupatula cholakwikacho ndikuchiritsa bwino capacitor kuti ipitirize kugwira ntchito. Chifukwa chake, DMJ-MC ili ndi nthawi yayitali yokhala ndi moyo komanso kudalirika kogwira ntchito popanda kulephera konse kwatsoka poyerekeza ndi ma capacitor achikhalidwe a electrolytic.

 

DMJ-MC metalized film capacitor ili ndi mitundu yosiyanasiyana ya mapulogalamu kuphatikizapo mitundu yonse ya ma frequency converters ndi inverters, photovoltaic inverter, wind power converter, EVs, HEVs, SVG, SVC ndi zida zina zoyendetsera mphamvu.

 

Kwa zaka 9 zapitazi, Wuxi CRE New Energy yakhala ikukonzekera ukadaulo wake wa capacitor wa filimu yopangidwa ndi zitsulo ndipo yakhala ikupanga zida zoyambirira (OEM) ku kampani yodziwika bwino yamagetsi ku America. DMJ-MC metalized film capacitor ndi imodzi mwa zinthu zodziwika bwino komanso zogulitsidwa kwambiri chifukwa imapereka magwiridwe antchito abwino komanso zabwino zambiri zikagwiritsidwa ntchito mu ma frequency converters ndi ma inverters. Ndi njira yodziwika bwino, yodalirika komanso yabwino kwa nthawi yayitali pamsika wovuta.
