Chojambulira chamagetsi champhamvu chomwe chapangidwa mwatsopano chokhala ndi mphamvu yodzichiritsa (DKMJ-S)
Chitsanzo cha Capacitor: DKMJ-S
Mawonekedwe:
1. Ma electrode a mtedza/zomangira zamkuwa, zosavuta kuyika
2. Ma CD achitsulo odzazidwa ndi utomoni wouma
3. Mphamvu yayikulu mu kukula kochepa kwa thupi
4. Kukana mphamvu yamagetsi okwera komanso mphamvu yodzichiritsa yokha
5. Kutha kugwira ntchito pansi pa mphamvu yamagetsi yamphamvu
6. Kukhala ndi Moyo Wautali ndi Kuchita Bwino Poyerekeza ndi Ma Electrolytic Capacitors
Mapulogalamu:
1. Kusunga ndi Kusefa Mphamvu mu DC-Link Circuit
2. Mapulogalamu a VSC-HVDC ozikidwa pa IGBT (Voltage Sourced Converter) Otumiza Mphamvu Pansi pa Dziko Pamtunda Wautali
3. Magetsi Ochokera Kugombe Ku Zilumba
4. Chosinthira Mphamvu ya Mphepo (PV), Chosinthira Mphamvu ya Mphepo
5. Magalimoto Amagetsi (ma EV) ndi Magalimoto Amagetsi Osakanikirana (ma HEV)
6. Mitundu Yonse ya Ma Frequency Converters ndi Inverters
7. SVG, Zipangizo Zoyang'anira Mphamvu za SVC

Wodzipangira Wodzipangira Mafilimu Wodzipangira Wokha wa Ma EV ndi HEV Applications
Ma capacitor apamwamba a mafilimu amphamvu okhala ndi ukadaulo wodzichiritsa wokha ndi amodzi mwa mayankho amagetsi amphamvu omwe mainjiniya a EV ndi HEV angadalire kuti akwaniritse kukula kolimba, kulemera, magwiridwe antchito, komanso kudalirika kosalephera konse pamsika wovutawu.

Mphamvu yamagetsi yamagetsi yamagetsi
CRE imapanga mitundu iyi ya ma capacitor amagetsi amphamvu:
Filimu ya pulasitiki yopangidwa ndi chitsulo ya MKP, yaying'ono, yotsika mtengo. Ma capacitor onse amadzichiritsa okha, mwachitsanzo, kuwonongeka kwa magetsi kumachira pakangopita mphindi zochepa ndipo sikupanga ma short circuit.

Capacitor yapamwamba ya DC link film capacitor yamagetsi oyendetsera ma drivetrain inverters
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

Kachipangizo ka filimu kopangidwa ndi zitsulo kogwiritsira ntchito magetsi (DMJ-MC)
Ma capacitor amagetsi amagetsi a DMJ-MC mndandanda
Ma capacitor a filimu ya polypropylene amatha kugwiritsidwa ntchito bwino kwambiri.
1. Zinthu zochepa kwambiri zotulutsa madzi (tan δ)
2. Zinthu zabwino kwambiri (Q)
3. mitengo yotsika ya inductance (ESL)
4. Palibe maikolofoni poyerekeza ndi ma capacitor a ceramic
5. Kapangidwe kachitsulo kali ndi mphamvu zodzichiritsa zokha
6. Ma voltages okwera kwambiri
7. Mphamvu yamagetsi yothamanga kwambiri imapirira
-
Capacitor yamafilimu yodzichiritsa yokha yamagetsi ambiri muzipangizo zamagetsi ndi zamagetsi
Ma Capacitors a Filimu a PP amagetsi amphamvu
CRE inayang'ana kwambiri malamulo okhudza chitetezo cha capacitor ndi magwiridwe antchito a zida.
Ma capacitor a filimu ya PP ali ndi mphamvu yotsika kwambiri yoyamwa ma dielectric, zomwe zimapangitsa kuti akhale oyenera kugwiritsa ntchito monga ma sample-and-hold applications, ndi ma audio circuits. Amapezeka pa ma application olondola awa m'malo ochepa kwambiri.

Yankho la capacitor youma yopangidwa mwamakonda kuti igwire njanji 3000VDC
Mndandanda wa capacitor wa sitima yapamtunda ya DKMJ-S
1. Chojambulira chodzichiritsa chokha komanso chouma chokhala ndi chikwama chachitsulo chosapanga dzimbiri
2. Filimu ya PP yopangidwa ndi zitsulo yomwe imatsimikizira kuti sizimadzipangitsa kudzidalira kwambiri
3. Kukana kwambiri kuphulika komanso kudalirika kwambiri
4. Kuchotsa mphamvu yochulukirapo sikuonedwa kuti ndikofunikira
5. Chophimba pamwamba cha capacitor chimatsekedwa ndi epoxy yozimitsa yokha.
6. Ukadaulo wa patent wa CRE umatsimikizira kuti mphamvu ya injini siigwira ntchito bwino.
