Transformer ya 1250 kVA ili ndi mphamvu yowoneka bwino ya 1250 kilovolt-amperes. Mwachidziwitso, izi zikutanthauza kuti imatha kupereka mpaka 1,250,000 volt-amperes yamagetsi pansi pa voliyumu yake yovotera, ma frequency, nyengo yozizira, komanso malo oyika.
Komabe, katundu weniweni wogwiritsidwa ntchito amadalira magetsi, gawo, mphamvu yamagetsi, mtundu wa katundu, kutentha kozungulira, njira yozizirira, mikhalidwe yoyika, ndi malire a chitetezo. A 1250 kva transformer ikhoza kuthandizira nyumba yayikulu yamalonda, malo ochitiramo mafakitale, mzere wopanga, malo opangira data, kapena makina ogawa, koma ziyenera kufananizidwa mosamala ndi zomwe magetsi amafunikira.
Kodi 1250 kVA Imatanthauza Chiyani?
Mulingo wa kVA wa thiransifoma umawonetsa mphamvu zake zowoneka bwino. Zimaphatikiza ma voltage ndi apano popanda kutengera mphamvu inayake.
Njira yoyambira ndi:
kVA = voteji x panopa x gawo factor / 1000
Kwa transformer ya magawo atatu:
kVA = 1.732 x voteji x panopa / 1000
Kwa thiransifoma ya gawo limodzi:
kVA = voteji x panopa / 1000
Chifukwa mayunitsi ambiri a 1250 kVA ndi osinthira magawo atatu, mphamvu yapano nthawi zambiri imawerengedwa ndi fomula ya magawo atatu.
Kodi Transformer ya 1250 kVA Yamakono Ingaperekedwe Bwanji?
Zomwe zilipo panopa zimadalira mphamvu yachiwiri.
Kwa thiransifoma ya 1250 kVA ya magawo atatu, pafupifupi yodzaza ndi mphamvu zonse ndi:
- Pa 400V: pafupifupi 1,804 amps
- Pa 415V: pafupifupi 1,739 amps
- Pa 480V: pafupifupi 1,504 amps
- Pa 690V: pafupifupi 1,046 amps
- Pa 11kV: pafupifupi 66 amps
Makhalidwe awa amawerengedwa pogwiritsa ntchito njira yapano ya magawo atatu:
Panopa = kVA x 1000 / (1.732 x voteji)
Mwachitsanzo, pa 400V:
1,250 x 1000 / (1.732 x 400) = pafupifupi 1,804A
Izi zikutanthauza a 1250 kva transformer ogwira ntchito pa 400V magawo atatu amatha kupereka mozungulira 1,804 amps pa katundu wathunthu, potengera momwe amagwirira ntchito.
Kodi Transformer ya 1250 kVA ingathandize bwanji kW?
kVA si yofanana ndi kW. kW imayesa mphamvu zenizeni zogwirira ntchito, pomwe kVA imayesa mphamvu yowoneka bwino. Ubale umadalira mphamvu.
Fomula ndi:
kW = kVA x mphamvu yamagetsi
Zitsanzo:
- Mphamvu ya 1.0: 1250 kW
- Mphamvu ya 0,95: 1187.5 kW
- Mphamvu ya 0.90: 1125 kW
- Mphamvu ya 0,85: 1062.5 kW
- Mphamvu ya 0.80: 1000 kW
Muzinthu zambiri zamafakitale ndi zamalonda, mphamvu yamagetsi imatha kuyambira 0.8 mpaka 0.95 kutengera katundu wamagalimoto, zoyendetsa, zowunikira, ma capacitor, ndi zida zowongolera mphamvu.
Chifukwa chake, thiransifoma ya 1250 kVA imatha kuthandizira pafupifupi 1000 kW mpaka 1187 kW pamapulogalamu ambiri enieni, kutengera mphamvu yamagetsi.
Kodi Transformer Iyenera Kukwezedwa mpaka 100%?
Ngakhale thiransifoma imatha kuvoteredwa kuti igwire ntchito yodzaza, mainjiniya ambiri amapewa kuyiyendetsa mosalekeza pa 100% pokhapokha kapangidwe kake kamalola. Chandamale chotsegulira chitha kuphatikiza malire pakukulitsa kwamtsogolo, kukwera kwa kutentha, katundu wa harmonic, injini yoyambira pano, komanso kufunikira kwanyengo.
Zolinga zodziwika bwino zakukonzekera zikuphatikizapo:
- Normal mosalekeza katundu
- Kufuna pachimake
- Chiyambi cha ma motors akuluakulu
- Kusokonezeka kwa Harmonic kuchokera ku ma drive kapena machitidwe a UPS
- Kutentha kozungulira
- Njira yozizira
- Malo olowera mpweya
- Kukula kwa katundu
- Malamulo amagetsi am'deralo
- Kulumikizana kwa zida zoteteza
Kwa kudalirika kwanthawi yayitali, ma projekiti ambiri amakula thiransifoma kotero kuti ntchito yabwinobwino imakhalabe yocheperako. Njira yeniyeni yonyamulira iyenera kutsimikiziridwa ndi mainjiniya amagetsi oyenerera.
Ntchito Zofananira za Transformer ya 1250 kVA
Transformer ya 1250 kVA imagwiritsidwa ntchito nthawi zambiri pamakina akuluakulu amagetsi.
Zomwe zimagwiritsidwa ntchito ndizo:
- Mafakitole
- Mapaki a mafakitale
- Nyumba zamalonda
- Zipatala
- Ma data center
- Malo ogulitsa
- Malo opangira madzi
- Ntchito zamigodi
- Mphamvu za dzuwa
- Makina osonkhanitsira mphamvu zamphepo
- Kuyika makina akuluakulu
- Malo ogawa
A 1250 kva transformer ikhoza kutumizira mitundu yambiri ya katundu, koma mbiri ya katunduyo iyenera kuwunikiridwa musanasankhe komaliza.
Zinthu Zomwe Zimakhudza Kutha Kwa Katundu
Mtengo wa Voltage
Mulingo womwewo wa thiransifoma kVA udzatulutsa mitundu yosiyanasiyana yapano pamagetsi osiyanasiyana. Kutsika kwamagetsi kumatanthawuza kukwezedwa kwamphamvu kwa kVA komweko.
Mphamvu Factor
Mphamvu zopanda mphamvu zimachepetsa mphamvu yeniyeni yogwiritsira ntchito kW. Kuwongolera kwamphamvu kungathandize kukonza magwiridwe antchito ndikuchepetsa kufunikira kwa thiransifoma.
Njira Yozizirira
Zosintha zomizidwa ndi mafuta komanso zowuma zimatha kukhala ndi mawonekedwe ozizirira osiyanasiyana. Mpweya wachilengedwe, mpweya wokakamizidwa, mpweya wachilengedwe wamafuta, kapena kuziziritsa kothandizidwa ndi fan kumatha kusokoneza kutulutsa kosalekeza.
Kutentha
Kutentha kwakukulu kozungulira kumatha kuchepetsa kutsitsa kwa thiransifoma. Ngati malo oyikapo akutentha kapena mulibe mpweya wabwino, angafunikire kuwongolera.
Harmonics
Katundu wopanda mzere monga ma frequency frequency drives, rectifiers, UPS system, ndi kuyatsa kwina kwa LED kumatha kupanga kutentha kwamtundu. Izi zingafunike chosinthira mwapadera kapena kutsitsa kutsitsa.
Mtundu Wonyamula
Katundu wamagalimoto, makina owotcherera, ma compressor, ndi zida zolemera zamafakitale zitha kupanga mafunde akulu. Transformer iyenera kugwira ntchito zonse zothamanga komanso zoyambira.
Momwe Mungasankhire Transformer ya 1250 kVA
Musanasankhe chosinthira, ogula ayenera kutsimikizira:
- Voltage yoyamba
- Mphamvu yachiwiri
- Gawo ndi pafupipafupi
- kVA mlingo
- Mtundu wa katundu
- Mphamvu yamagetsi
- Njira yozizira
- Kuyika chilengedwe
- Mpanda wamkati kapena wakunja
- Kalasi ya insulation

- Dongosolo lakukulitsa m'tsogolo
Transformer iyeneranso kufananizidwa ndi switchgear yoyenera, zingwe, zida zodzitetezera, makina oyambira pansi, komanso kapangidwe ka mpweya wabwino.
Zolakwa Zomwe Muyenera Kuzipewa
Cholakwika chimodzi chofala ndikusokoneza kVA ndi kW. Transformer ya 1250 kVA nthawi zonse simapereka 1250 kW pokhapokha mphamvu yamagetsi ndi 1.0.
Kulakwitsa kwina ndikunyalanyaza magetsi. Mphamvu zamakono zikusintha kwambiri pakati pa 400V, 480V, ndi makina apakati-voltage.
Kulakwitsa kwachitatu ndikukulitsa thiransifoma pazolemetsa zamasiku ano. Ngati kukula kwamtsogolo kungathe, mapangidwewo angafunikire malire owonjezera.
Mapeto
Mphamvu ya thiransifoma ya 1250 kVA ndi 1,250,000 volt-amperes. Kutulutsa kwake komweko kumadalira mphamvu yamagetsi, ndipo mphamvu yake yeniyeni ya kW imadalira mphamvu yamagetsi. Pa 400V magawo atatu, imatha kupereka pafupifupi 1,804 amps. Pa 480V magawo atatu, imatha kupereka pafupifupi 1,504 amps.
Pogwira ntchito, a 1250 kva transformer ziyenera kusankhidwa ndikuyikidwa molingana ndi voteji, mphamvu yamagetsi, kuzizira, mbiri ya katundu, kutentha kozungulira, zomwe zili ndi harmonic, ndi zosowa zowonjezera zamtsogolo. Kukula kolondola kumathandizira kugwira ntchito motetezeka, kuchita bwino, komanso moyo wautali wantchito ya thiransifoma.
