Ma capacitors a Wind Power Plants

CREyapanga ma capacitor apamwamba kwambiri opangira mafilimu okhala ndi ma voliyumu okwera kwambiri, moyo wautali wogwiritsa ntchito komanso kuthekera kwapakali pano.Ma capacitor amakanema apamwamba ndi abwino kwambiri pakupangira mphamvu zowonjezera mphamvu, monga ma inverters amagetsi adzuwa, zosefera zotulutsa za AC mumagetsi akunyanja, ndi zina zambiri.

Dziwani zambiri kuchokera pansipa:

Metallized polypropylene film capacitors (MKP)

Zomwe zimagwiritsidwa ntchito

1. DC ulalo2. Kusefa kwa AC3. IGBT4. Kunyoza5. Kusungirako mphamvu

Reference muyezo

1. IEC 61071;IEC61881;ISO9001;UL E496566;VDE;IATF;RoHS&kufika.

Zanyengo

1. Max.ntchito kutentha: 105 °C
2. Gulu lanyengo: 55/100/56

Zomangamanga

1. Dielectric: polypropylene (PP)
2. Ukadaulo wa capacitor wovulala wokhala ndi mndandanda wamkatikulumikizana
3. Chovala chapulasitiki (UL 94 V-0)
4. Kusindikiza kwa epoxy resin (UL 94 V-0)

Mawonekedwe

1. Mkulu kugunda mphamvu ndi mkulu kukhudzana kudalirika
2. Otsika kwambiri inductance
3. RoHS-yatsatiridwa
4. Zopangidwa mwamakonda

Pokwerera

1. Zomangira zingwe, mkuwa wothira kapena mkuwa
2. Zikhomo
3. Stud/screws
4. Bakelite
5. Waya wamagetsi

Kuyika chizindikiro

Chizindikiro cha wopanga, kachidindo, kalembedwe (MKP)
Kuthekera kovotera (kolembedwa), kapu.tolerance (code letter)
Adavotera magetsi a DC, tsiku lopangidwa (lolembedwa)
Logo yamakasitomala imapezeka ngati ikufunika

3-gawo AC fyuluta capacitor

DC-Link capacitor

Njira yotumizira

1. Zochuluka 2. Zopangidwa mwamakonda

Zosungirako ndi zogwirira ntchito

Osagwiritsa ntchito kapena kusunga ma capacitor mumlengalenga wowononga, makamaka komwe kuli gasi wa chloride, gasi wa sulfide, asidi, alkali, mchere ndi zina zotero.M'malo afumbi, kukonza ndikuyeretsa pafupipafupi makamaka ma terminals kumafunika kupewa njira yolumikizirana pakati pa magawo ndi/kapena magawo ndi nthaka.
Kutentha kwakukulu kosungirako ndi 85 °C.

Chiyembekezo cha moyo wautumiki

Zida zamagetsi sizikhala ndi nthawi yautumiki yopanda malire;izi zikugwiranso ntchito kwa ma capacitors odzichiritsa okha, nawonso.
Kutalika kwa moyo wautumiki kumatha kusiyanasiyana kutengera momwe capacitor imagwiritsidwa ntchito.
