Isiguquli se-1250 kVA sinamandla abonakalayo angama-1250 kilovolt-amperes. Ngokwezinto eziphathekayo, oku kuthetha ukuba inokubonelela ukuya kuthi ga kwi-1,250,000 ye-volt-amperes yomthwalo wombane phantsi kombane olinganisiweyo, amaza, imeko yokupholisa, kunye nendawo yokufakela.
Nangona kunjalo, umthwalo wokwenyani osebenzisekayo uxhomekeke kumbane, isigaba, amandla ombane, uhlobo lomthwalo, ubushushu bendawo, indlela yokupholisa, iimeko zofakelo, kunye nomda wokhuseleko. A 1250 kva isiguquli inokuxhasa isakhiwo esikhulu sorhwebo, iworkshop yoshishino, umgca wokuvelisa, indawo yedatha, okanye inkqubo yokuhambisa, kodwa kufuneka ihambelane ngononophelo nemfuno yombane.
Ithetha ukuthini i-1250 kVA?
Ireyithingi ye-kVA ye-transformer ichaza amandla ayo abonakalayo. Idibanisa i-voltage kunye yangoku ngaphandle kokucinga into ethile yamandla.
Ifomula esisiseko yile:
kVA = amandla ombane x okwangoku x isigaba senqanaba / 1000
Kwisiguquli esinezigaba ezithathu:
kVA = 1.732 x amandla ombane x okwangoku / 1000
Kwisiguquli senqanaba elinye:
kVA = amandla ombane x okwangoku / 1000
Ngenxa yokuba uninzi lweeyunithi ezinkulu ze-1250 kVA ziziguquli zesigaba esithathu, umthamo wangoku udla ngokubalwa kunye nefomula yezigaba ezithathu.
Ingakanani iSibonelelo seSiguquli sangoku se-1250 kVA?
Imveliso yangoku ixhomekeke kumbane wesibini.
Kwinqanaba lesithathu le-1250 kVA isiguquli, ubungakanani bomthwalo opheleleyo wangoku:
- Kwi-400V: malunga ne-1,804 amps
- Kwi-415V: malunga ne-1,739 amps
- Kwi-480V: malunga ne-1,504 amps
- Kwi-690V: malunga ne-1,046 amps
- Kwi-11kV: malunga ne-66 amps
La maxabiso abalwa kusetyenziswa ifomyula yangoku yesigaba esithathu:
Okwangoku = kVA x 1000 / (1.732 x amandla ombane)
Umzekelo, kwi-400V:
1,250 x 1000 / (1.732 x 400) = malunga ne-1,804A
Oku kuthetha a 1250 kva isiguquli ukusebenza kwi-400V yesigaba sesithathu sinokunikezela ngethiyori malunga ne-1,804 amps kumthwalo ogcweleyo, kuqikelelwa iimeko zokusebenza ezilinganisiweyo.
Zingaphi iikW ezinokuthi zibe neNkxaso ye-1250 kVA yesiGuquli?
I-kVA ayifani ne-kW. I-kW ilinganisa amandla okwenene okusebenza, ngelixa i-kVA ilinganisa amandla abonakalayo. Ubudlelwane buxhomekeke kwinto yamandla.
Ifomula yile:
kW = kVA x umba wamandla
Imizekelo:
- Kwi-1.0 into yamandla: 1250 kW
- Kwi-0.95 factor factor: 1187.5 kW
- Kwi-0.90 factor factor: 1125 kW
- Kwi-0.85 factor factor: 1062.5 kW
- Kwi-0.80 factor factor: 1000 kW
Kwiinkqubo ezininzi zoshishino kunye nezorhwebo, amandla ombane anokuthi asuse malunga ne-0.8 ukuya kwi-0.95 ngokuxhomekeke kwimithwalo yemoto, ukuqhuba, ukukhanya, i-capacitors, kunye nezixhobo zokulungisa amandla.
Ngoko ke, i-1250 kVA transformer inokuxhasa malunga ne-1000 kW ukuya kwi-1187 kW kwizinto ezininzi zokwenyani, kuxhomekeke kumandla ombane.
Ngaba iTransformer kufuneka ilayishwe ukuya kwi-100%?
Nangona i-transformer inokulinganiswa ngokusebenza komthwalo ogcweleyo, iinjineli ezininzi ziyakuphepha ukuyiqhuba ngokuqhubekayo kwi-100% ngaphandle kokuba uyilo luvumela oko. Ithagethi yokulayisha ebonakalayo inokubandakanya umda wokwandiswa kwexesha elizayo, ukunyuka kwamaqondo obushushu, imithwalo ye-harmonic, ukuqala kwemoto yangoku, kunye nemfuno yamaxesha onyaka.
Iingqwalasela zocwangciso eziqhelekileyo ziquka:
- Umthwalo oqhubekayo oqhelekileyo
- Imfuno ephezulu

Izinto Ezichaphazela Umthamo Womthwalo
Ixabiso lombane
Ukulinganisa okufanayo kwe-kVA ye-transformer kuya kuvelisa amaxabiso ahlukeneyo akhoyo ngoku kwii-voltages ezahlukeneyo. Amandla ombane asezantsi athetha umsinga ophezulu kwi-kVA efanayo.
Amandla Factor
Amandla alambathayo anciphisa amandla okwenene asebenzisekayo e-kW. Ukulungiswa kwezinto zamandla kunokunceda ukuphucula ukusebenza kwenkqubo kunye nokunciphisa imfuno kwi-transformer.
Indlela yokupholisa
Iziguquli zeoyile ezintywiliselweyo kunye nezomileyo zinokuba noyilo olwahlukileyo lokupholisa. Umoya wendalo, umoya onyanzelwayo, umoya wendalo we-oyile wendalo, okanye ukupholisa okuncediswa yifeni kunokuchaphazela ukuqhubeka kokulayisha.
Ubushushu
Ubushushu obuphezulu be-ambient bunokunciphisa umthamo wokulayisha i-transformer. Ukuba indawo yofakelo ishushu okanye ingena moya kakubi, kungafuneka ukuthotywa.
IiHarmonics
Imithwalo engahambelaniyo efana nedrive frequency drives, iirectifiers, iinkqubo ze-UPS, kunye nezinye izibane ze-LED zinokwenza ukufudumeza kwe-harmonic. Oku kunokufuna i-transformer ehlelwe ngokukodwa okanye ukunciphisa ukulayisha.
Uhlobo Lomthwalo
Imithwalo yeemoto, oomatshini bokuwelda, iicompressors, kunye nezixhobo ezinzima zemizi-mveliso zinokudala imisinga ephezulu yokungena. I-transformer kufuneka iphathe zombini umthwalo osebenzayo kunye neemeko zokuqala.
Indlela yokukhetha i-1250 kVA Transformer
Ngaphambi kokukhetha i-transformer, abathengi kufuneka baqinisekise:
- Umbane wokuqala

I-transformer kufuneka ihambelane ne-switchgear efanelekileyo, iintambo, izixhobo zokukhusela, inkqubo yokumisa, kunye nokuyila umoya.
Iimpazamo Eziqhelekileyo Emaziphephe
Impazamo enye eqhelekileyo kukubhidanisa i-kVA nge-kW. I-1250 kVA transformer ayisoloko ibonelela nge-1250 kW ngaphandle kokuba umbane we-1.0.
Enye impazamo kukungahoyi umbane. Umthamo wangoku utshintsha kakhulu phakathi kwe-400V, i-480V, kunye neenkqubo zombane ophakathi.
Impazamo yesithathu kukulinganisa i-transformer kuphela kumthwalo wanamhlanje. Ukuba ulwando lwexesha elizayo lunokwenzeka, uyilo lunokufuna umda owongezelelweyo.
Ukuqukumbela
Umthamo womthwalo we-1250 kVA transformer yi-1,250,000 volt-amperes. Imveliso yayo yangoku ixhomekeke kumbane, kwaye umthamo wayo we-kW wokwenyani uxhomekeke kumandla ombane. Kwi-400V yesigaba sesithathu, inokubonelela malunga ne-1,804 amps. Kwi-480V yesigaba sesithathu, inokubonelela malunga ne-1,504 amps.
Kwintsebenzo ebonakalayo, a 1250 kva isiguquli kufuneka ikhethwe kwaye ilayishwe ngokwevoltheji, amandla ombane, imeko yokupholisa, iprofayili yomthwalo, ubushushu be-ambient, umxholo we-harmonic, kunye neemfuno zokwandiswa kwexesha elizayo. Ubungakanani obuchanekileyo buxhasa ukusebenza okukhuselekileyo, ukusebenza kakuhle, kunye nobomi benkonzo yokuguqula ixesha elide.
