GTO snubber capacitor mu zida zamagetsi zamagetsi

Kachipangizo ka GTO kopanda mphamvu kali ndi zida zamagetsi zamagetsi Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Ma circuit odulira magetsi ndi ofunikira kwambiri pa ma diode omwe amagwiritsidwa ntchito posintha ma circuit. Amatha kupulumutsa diode ku ma spikes ochulukirapo, omwe angabuke panthawi yobwezeretsa magetsi.

Kutentha kogwira ntchito	Kutentha Kwambiri. Kugwira ntchito., Pamwamba, kutentha kwakukulu: + 85℃ Kutentha kwapamwamba: +85℃ Kutentha kwapansi kwa gulu: -40℃
kuchuluka kwa mphamvu	0.22～3μF
Voltage yoyesedwa	3000V.DC～10000V.DC
Cap.tol	±5%(J) ;±10%(K)
Pitirizani ndi magetsi	1.35Un DC/10S
Chinthu choyambitsa kutayikira	tgδ≤0.001 f=1KHz
Kukana kutchinjiriza	C≤0.33μF RS≥15000 MΩ (pa 20℃ 100V.DC 60S) C＞0.33μF RS*C≥5000S (pa 20℃ 100V.DC 60S)
Limbanani ndi strike current	onani pepala la deta
Chiyembekezo cha moyo	100000h(Un; Θhotspot≤70°C)
Muyezo wofunikira	IEC 61071;

Mbali

1. Tepi ya Mylar, Yotsekedwa ndi utomoni;

2. Nsalu za mtedza wa mkuwa;

3. Kukana mphamvu yamagetsi yapamwamba, tgδ yotsika, kukwera kwa kutentha kochepa;

4. ESL ndi ESR yotsika;

5. Kugunda kwamphamvu kwamphamvu.

Kugwiritsa ntchito

1. GTO Snubber.

2. Amagwiritsidwa ntchito kwambiri mu zida zamagetsi zamagetsi pamene mphamvu yamagetsi ikukwera, chitetezo cha mayamwidwe amagetsi chikukwera.
