Ama-capacitor ebhasi le-DC ama-Converter asekelwe kwi-IGBT ku-Traction Equipment

Ama-capacitor ebhasi le-DC ama-Converter asekelwe ku-IGBT ku-Traction Equipment Isithombe Esifakiwe

Incazelo emfushane:

Uchungechunge lwe-DMJ-MC lwebhasi le-DC capacitor

Ama-capacitor efilimu anensimbi enziwe ngamafilimu amabili anensimbi anefilimu yepulasitiki njenge-dielectric.

I-aluminium metallization encane kakhulu (~ 0.03 μm[2]) efakwe nge-vacuum ifakwa ohlangothini olulodwa noma zombili ukuze isebenze njengama-electrode.

Ama-capacitor efilimu ye-polypropylene

Ama-capacitor e-dielectric e-polypropylene enziwe ngensimbi alungisiwe,

Lokhu kulungiselelwa kungaba nezakhiwo "eziziphilisayo", ngoba ukuwohloka kwe-dielectric noma izifunda ezimfushane phakathi kwama-electrode akuholeli ekubhujisweni kwengxenye.

Ngalo mklamo oyisisekelo, kungenzeka ukwenza imikhiqizo esezingeni eliphezulu njenge-capacitors “engenasici” nokukhiqiza ama-wound capacitors anenani elikhulu le-capacitance (kufika ku-100 μF nangaphezulu) ezimweni ezincane (ukusebenza kahle kwe-volumetric ephezulu) uma kuqhathaniswa nokwakhiwa kwefilimu/i-foil.

I-CRE inamandla ngenxa yamandla ayo e-R&D, sakha i-capacitor ngokuya nge-capacitance elinganisiwe, i-voltage elinganisiwe, indawo yokusebenza, njll.

Isici

1. Ubuchwepheshe bohlobo olomile;

2. Ububanzi bokushisa;

3. Amandla okumelana nama-voltage aphezulu kakhulu;

4. Ukulahleka kukagesi okuphansi;

5. Iyakwazi ukubhekana nokuphakama kwamandla kagesi okuphezulu nokuphezulu kakhulu.

Isicelo

Ama-capacitor efilimu asetshenziswa emishinini kagesi apakishwe ngezitayela ezivamile nezezimboni: i-axial, i-radial, i-cylindrical, i-metal case, njll.
