Capacitor yapamwamba ya polypropylene ya Metallized mu ntchito zamagetsi amphamvu kwambiri
Ma capacitor a CRE Polypropylene power film capacitors nthawi zambiri amagwiritsidwa ntchito pamagetsi amphamvu kwambiri chifukwa cha mphamvu yawo yayikulu ya dielectric, kuchuluka kochepa kwa volumetric, komanso dielectric constant yotsika kwambiri (tanδ). Ma capacitor athu amakumananso ndi kutayika kochepa ndipo, kutengera zomwe zimagwiritsidwa ntchito, amatha kupangidwa ndi malo osalala kapena amdima.

Kapangidwe ka Power Film Capacitor ka Galimoto Yamagetsi
1. Phukusi la pulasitiki, losindikizidwa ndi utomoni wa epoxy wofewa, zingwe zamkuwa, kukula kosinthidwa
2. Kukana ku filimu ya polypropylene yachitsulo yodzichiritsa yokha, yamagetsi okwera
3. ESR yotsika, kuthekera kogwiritsa ntchito mphamvu yamagetsi ya ripple yambiri
4. Low ESR, imachepetsa bwino mphamvu yamagetsi yobwerera
5. Mphamvu yayikulu, kapangidwe kakang'ono

Chotenthetsera chatsopano cha Induction chopangidwa mwatsopano cha ng'anjo yapakati pafupipafupi
Ma capacitor otenthetsera opangidwa kuti agwiritsidwe ntchito ndi ng'anjo zotenthetsera ndi zotenthetsera, kuti akonze mphamvu kapena mawonekedwe a dera.
Ma capacitor ndi a dielectric okhala ndi filimu yonse omwe amadzazidwa ndi mafuta oteteza chilengedwe, osawononga chilengedwe. Amapangidwa ngati mayunitsi amoyo ozizira ndi madzi (mayunitsi akufa ngati apemphedwa). Kapangidwe ka magawo ambiri (kugogoda) komwe kumathandiza kuti magetsi aziyenda bwino komanso kusintha ma resonance circuits ndi chinthu chofunikira kwambiri. Kutentha koyenera komanso kuyenda kwa madzi ndikofunikira kwambiri.
Mphamvu Yosiyanasiyana: mpaka 6000 uF
Ma Voltage Range: 0.75kv mpaka 3kv
Muyezo Wofotokozera:GB/T3984.1-2004
IEC60110-1：1998

Kapepala ka filimu ya DC yolumikizidwa ndi PCB yopangidwira inverter ya PV
1. Kuphimba chipolopolo cha pulasitiki, kulowetsedwa kwa utomoni wouma;
2. zingwe zokhala ndi mapini, kapangidwe kakang'ono, zosavuta kukhazikitsa;
3. ESL ndi ESR yotsika;
4. Kugunda kwamphamvu kwamphamvu.
5. Chitsimikizo cha UL;
6. Kutentha kwakukulu kogwira ntchito: -40 ~ +105℃
-
Filimu yachitsulo ya IGBT Snubber capacitor
1. Chikwama cha pulasitiki, Chotsekedwa ndi utomoni;
2. Ma lead opangidwa ndi zitini okhala ndi mkuwa, osavuta kuyika pa IGBT;
3. Kukana mphamvu yamagetsi yapamwamba, tgδ yotsika, kukwera kwa kutentha kochepa;
4. ESL ndi ESR yotsika;
5. Kugunda kwamphamvu kwamphamvu.

Chotsukira Makanema Champhamvu Kwambiri Chopangira Makina Owotcherera (SMJ-TC)
Chitsanzo cha Capacitor: SMJ-TC
Mawonekedwe:
1. Ma electrode a mtedza wa mkuwa
2. Kukula kochepa thupi komanso kuyika kosavuta
3. Ukadaulo wa Mylar tape winding
4. Kudzaza utomoni wouma
5. Kutsika kwa Ma Series Ofanana (ESL) ndi Kukana kwa Ma Series Ofanana (ESR)
Mapulogalamu:
1. GTO Snubber
2. Mphamvu Yowonjezera Mphamvu ndi Kuteteza Mphamvu Yowonjezera Mphamvu pa Zida Zamagetsi
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.
-
Ma capacitor a Axial GTO osakhala ndi mphamvu
Ma capacitor awa ndi oyenera kupirira ma pulse amphamvu omwe nthawi zambiri amakumana ndi chitetezo cha GTO. Ma axial connections amalola kuchepetsa kulowerera kwa ma series ndikupereka makina olimba olumikizirana ndi magetsi odalirika komanso kutentha bwino komwe kumapangidwa panthawi yogwira ntchito.
-
Kutaya pang'ono kwa dielectric ya polypropylene film Snubber capacitor yogwiritsira ntchito IGBT
Ma capacitor a IGBT snubber osiyanasiyana a CRE akutsatira malamulo a ROHS ndi REACH.
1. Makhalidwe oletsa moto amatsimikiziridwa pogwiritsa ntchito pulasitiki yotchingira ndi epoxy yomwe imagwirizana ndi UL94-VO.
2. Masitayilo a terminal ndi kukula kwa ma cases kumatha kusinthidwa.
