Metallized polypropylene film capacitor yamagetsi & kutembenuka

Metallized polypropylene film capacitor for power supply & conversion Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Ma crystalline segmented metallized polypropylene capacitors ndi gawo lazosankha zambiri Zosefera za DC, kusungirako mphamvu ndi ntchito zofananira zazaka za 21st.

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.
