Ma Capacitors a DC Bus a IGBT-Based Converters mu Traction Apparatus

Kufotokozera Kwachidule:

DC basi capacitor DMJ-MC mndandanda

Ma capacitor a filimu yachitsulo amapangidwa ndi mafilimu awiri achitsulo okhala ndi filimu yapulasitiki ngati dielectric.

Chitsulo chopyapyala kwambiri cha aluminiyamu (~ 0.03 μm[2]) choyikidwa mu vacuum chimayikidwa mbali imodzi kapena zonse ziwiri kuti chikhale ngati ma electrode.

Ma capacitor a filimu ya polypropylene

Ma capacitor a dielectric a polypropylene film dielectric a DC okhazikika,

Kapangidwe kameneka kangakhale ndi makhalidwe "odzichiritsa okha", chifukwa kuwonongeka kwa dielectric kapena ma circuits afupi pakati pa ma electrode sikuti kumayambitsa kuwonongeka kwa gawolo.

Ndi kapangidwe kameneka, n'zotheka kupanga zinthu zapamwamba kwambiri monga ma capacitor a "zero defect" ndikupanga ma wound capacitor okhala ndi capacitance yayikulu (mpaka 100 μF ndi yayikulu) m'malo ang'onoang'ono (volumetric efficiency) poyerekeza ndi kapangidwe ka filimu/foil.

CRE ndi yolimba chifukwa cha luso lake la R&D, timapanga capacitor malinga ndi capacitance yoyesedwa, voltage yoyesedwa, malo ogwirira ntchito, ndi zina zotero.

Mbali

1. Ukadaulo wa mtundu wouma;

2. Kutentha kwakukulu;

3. Kutha kupirira ma voltages okwera kwambiri;

4. Kutayika kochepa kwa magetsi;

5. Wokhoza kuthana ndi mafunde amphamvu komanso okwera kwambiri.

Kugwiritsa ntchito

Ma capacitor a mafilimu ogwiritsidwa ntchito pazida zamagetsi amapakidwa m'njira zodziwika bwino komanso zachizolowezi zamakampani: axial, radial, cylindrical, metal case, ndi zina zotero.
