Makanema Apamwamba Amakono Opangira Mafilimu a Makina Owotcherera (SMJ-TC)

High-Current Film Capacitor Snubber for Welding Machine (SMJ-TC) Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Chitsanzo cha Capacitor: SMJ-TC

Mawonekedwe:

1. Maelekitirodi a mtedza wa mkuwa

2. Small kukula thupi ndi unsembe zosavuta

3. Mylar tepi yokhotakhota luso

4. Kudzaza utomoni wowuma

5. Low Equivalent Series Inductance (ESL) ndi Equivalent Series Resistance (ESR)

Mapulogalamu:

1. GTO Snubber

2. Peak Voltage ndi Peak Current Absorption ndi Chitetezo pa Kusintha Chigawo mu Zida Zamagetsi

Zozungulira za snubber ndizofunikira kwa ma diode omwe amagwiritsidwa ntchito posintha ma circuit.Itha kupulumutsa diode ku ma spikes ochulukirapo, omwe angabwere panthawi yobwezeretsanso.

Mbali

1. Tepi ya Mylar, Yosindikizidwa ndi utomoni;

2. Mtedza wa mkuwa;

3. Kukana mphamvu yamagetsi, otsika tgδ, kutentha kwapansi;

4. ESL yochepa ndi ESR;

5. Kuthamanga kwakukulu Pakalipano.

Kugwiritsa ntchito

1. GTO Snubber.

2. Amagwiritsidwa ntchito kwambiri mu mphamvu zamagetsi zida pamene nsonga voteji, pachimake panopa mayamwidwe chitetezo.
