DC bus Capacitors yeIGBT-Based Converters muTraction Apparatus

Tsananguro pfupi:

DC bhazi capacitor DMJ-MC nhevedzano

Ma capacitor efirimu ane simbi anogadzirwa nemafirimu maviri ane simbi ane purasitiki se dielectric.

Metallization yakatetepa kwazvo (~ 0.03 μm[2]) yealuminium inoiswa mu vacuum inoiswa kune rimwe kana divi rese kuti ishande sema electrodes.

Macapacitor efirimu rePolypropylene

Macapacitor e polypropylene film dielectric dc akagadzirwa nesimbi,

Kugadzika uku kunogona kuva ne "kuzvigadzirisa" maitiro, pakuti kuputsika kwe dielectric kana ma short circuits pakati pema electrodes hazvireve kuti chikamu chacho chinoparadzwa.

Nekugadzirwa uku kwakakosha, zvinokwanisika kugadzira zvigadzirwa zvemhando yepamusoro zvakaita se "zero defect" capacitors uye kugadzira ma "wound capacitors" ane capacitance yakakura (kusvika ku100 μF uye yakakura) muzviitiko zvidiki (high volumetric efficiency) zvichienzaniswa nekugadzirwa kwefirimu/foil.

CRE yakasimba nekuda kwekugona kwayo R&D, tinogadzira capacitor zvichienderana ne rated capacitance, rated voltage, operating environment, nezvimwewo.

Chinhu

1. Tekinoroji yemhando yakaoma;

2. Kupisa kwakafara;

3. Kukwanisa kutsungirira voltages dzakanyanya;

4. Kurasikirwa kwemagetsi kwakaderera;

5. Inokwanisa kubata mafungu emvura akakwira uye akakwira kwazvo.

Kushandiswa

Ma capacitor emafirimu anoshandiswa mumidziyo yemagetsi akarongedzwa nenzira dzakajairika uye dzakajairika dzeindasitiri: axial, radial, cylindrical, metal case, nezvimwewo.
