Iyini i-Transformer engu-25 kVA

I-transformer engu-25 kVA iphatha amandla aphezulu abonakalayo angu-25,000 volt-amperes (VA), umkhiqizo we-voltage kanye nogesi kusekethe ye-AC.

I-“25” ku-25 kVA ibhekisela kumandla aphezulu e-transformer okusingatha amandla abonakalayo, hhayi amandla ayo angempela. Ukuze uthole amandla angempela okukhipha, cabanga nge-power factor yomthwalo oxhunyiwe. I-transformer engu-25 kVA ene-power factor engu-0.8 inomthamo wamandla wangempela wama-kilowatts angu-20 (kW).

Ububanzi obujwayelekile bamandla okufaka nokukhipha

Ama-voltage okukhipha ama-transformer angu-25 kVA avame ukufaka i-208V, 240V, kanye ne-120V. Ama-voltage angu-208V kanye ne-240V akhipha amandla emishini emikhulu, njengezinjini, imishini esindayo, kanye nezinto zikagesi ezinamandla amakhulu. Umphumela we-120V ufanelekela amadivayisi amancane, izibani, kanye nemishini yehhovisi evamile.

Izinhlobo zama-Transformers angu-25 kVA

Ama-Transformer Esigaba Esisodwa

Ama-transformer esigaba esisodwa avame ukusetshenziswa ekusetshenzisweni kwamandla angu-25 kVA. Lawa ma-transformer anezimbobo ezimbili: ukugoqa okuyinhloko kanye nokwesibili. Asebenza esigabeni esisodwa sokushintshana kwamandla (AC), okwenza afanelekele imithwalo kagesi yezindlu neyezentengiselwano elula.

Ama-Transformer Ezigaba Ezintathu

Ama-transformer angu-25 kVA anezigaba ezintathu asetshenziswa kabanzi ezindaweni zezimboni nezentengiselwano ngezinhlelo zokusebenza zamandla aphezulu. Anikeza ukusatshalaliswa kwamandla okusebenza kahle nokulinganiselwe uma kuqhathaniswa nama-transformer anezigaba esisodwa, okwenza afaneleke ukuphatha imithwalo emikhulu. Lawa ma-transformer anezimbobo ezintathu ezihlukene, isigaba ngasinye sibekwe eceleni kwama-degree angu-120, okuqinisekisa ukunikezwa kwamandla okuzinzile nokuqhubekayo.

Ama-transformer esigaba sesithathu anikeza izinzuzo eziningana ngaphezu kwama-transformer esigaba esisodwa. Avumela usayizi we-conductor oncishisiwe, i-power factor ethuthukisiwe, kanye nokulawulwa okungcono kwe-voltage. Ngaphezu kwalokho, anciphisa ukuphazamiseka kwe-harmonic, okuholela ekuhlinzekweni kwamandla okuzinzile kwemishini ebucayi.

Ukucaciswa Okubalulekile Nezici

Ukuphathwa kwamandla kanye nokucatshangelwa komthwalo

I-transformer engu-25 kVA inomthamo wamandla obonakalayo ophezulu ongu-25,000 volt-amperes (VA). Amandla abonakalayo angumkhiqizo we-voltage kanye nogesi kusekethe ye-AC. Amandla angempela alethwa emthwalweni, aziwa ngokuthi amandla angempela (alinganiswa ngama-watts), azoba ngaphansi kwamandla abonakalayo ngenxa yesici samandla samadivayisi axhunyiwe.

Izindlela zokupholisa (i-ONAN, i-ONAF) kanye namazinga omsindo

I-ONAN (Oil Natural Air Natural) kanye ne-ONAF (Oil Natural Air Forced) yizindlela ezimbili eziyinhloko zokupholisa ama-transformer angu-25 kVA. Ukupholisa i-ONAN kuncike ekujikelezweni kwemvelo kokujikeleza kukawoyela kanye nokushabalalisa ukushisa, okwenza kube inketho yokuthula efaneleke kakhulu ezindaweni zokuhlala nezindawo ezizwela umsindo. Kodwa-ke, i-ONAN inokusebenza okuphansi kokupholisa uma kuqhathaniswa ne-ONAF.

Ukupholisa kwe-ONAF kusebenzisa amafeni ukuphoqa ukujikeleza komoya nxazonke kwe-transformer, kuthuthukisa ukushabalaliswa kokushisa nokuvumela umthamo womthwalo ophezulu. Nakuba isebenza kahle kune-ONAN, i-ONAF ikhiqiza umsindo omningi ngenxa yamafeni.

Ama-transformer e-ONAN ngokuvamile anamazinga omsindo acishe abe ngu-40-50 dB, kuyilapho ama-transformer e-ONAF engafinyelela ku-60-70 dB.
Izici Ezithinta Amazinga Womsindo

Amadivayisi okuvikela adlulayo kanye nezinketho zokuhlanganisa

Amadivayisi okuvikela ugesi ongaphezu kwamandla, okuhlanganisa ama-circuit breakers, ama-fuse, kanye nama-thermal overload relay, avikela ama-transformer angu-25 kVA kanye nemishini exhunyiwe kugesi ongaphezu kwamandla abangelwa ugesi ongaphezu kwamandla avamile, ama-short circuit, noma izimo zamaphutha.

• Ama-circuit breaker anikeza izilungiselelo zokuhamba ezilungisekayo kanye nokusetha kabusha okulula ngemva kokukhubeka. Ama-fuse ahlinzeka ngokuvikela okusheshayo kodwa adinga ukushintshwa uma epheshuliwe.
• Ama-relay okushisa ngokweqile aqapha izinga lokushisa le-transformer kanye nokuwa lapho imikhawulo esethiwe idluliwe.
• Ama-fuse anciphisa ugesi asheshe aphazamise ugesi ongasebenzi kahle, anciphise umonakalo. Ama-fuse axoshayo asebenzisa izinto ezishintsha igesi ukuze acime ama-arcs. Izilinganiso zama-fuse kumele zihlanganiswe nogesi olinganiselwe kanye nomthamo we-transformer kanye nowe-short-circuit ukuze kuvikelwe kahle.

I-insulation kanye ne-weatherproofing

Izinto zokuvala umoya zama-transformer angu-25 kVA zifaka phakathi ama-epoxy resins, ama-silicone rubber, nama-polyurethane. Lezi zinto zinikeza amandla aphezulu e-dielectric, ukumelana nomswakama, amakhemikhali, kanye namazinga okushisa aphezulu, kanye namandla omshini nokuqina.

Ukuvikela isimo sezulu kubalulekile ekufakweni kwe-transformer yangaphandle . Izivalo ezingamelana nokugqwala ezenziwe ngensimbi engagqwali noma i-aluminium, kanye nama-gaskets kanye nezivalo, zivimbela ukungena kwamanzi nothuli. Umoya owanele uqeda ukushisa futhi uvimbele ukuminyana. Ukuvikelwa okwengeziwe kwezindawo ezinzima kufaka phakathi izembozo zokulwa nokugqwala, ukuqeda okumelana ne-UV, kanye nezikrini zamagundane.

Amathephu kanye nokulungiswa kokulawulwa kwe-voltage

Amathephu, izindawo zokuxhuma kuma-windings e-transformer, avumela ukulungiswa kokukhishwa kwe-voltage kuma-transformer angu-25 kVA. Amathephu amaningi ahlinzeka ngama-voltage ahlukahlukene, ngokuvamile angu-±5% noma ngaphezulu, ukuze avumelane nezidingo ezithile futhi akhokhele ukwehla kwe-voltage.

Amaswishi ompompi angenamthwalo avumela izinguquko zokusetha i-voltage ngaphandle kokukhipha i-transformer emthonjeni wamandla. Alula ukulungiswa kwe-voltage futhi anciphise isikhathi sokungasebenzi.

Izinto ezigoqekayo (i-aluminium vs. ithusi) kanye nemiphumela yazo

Ama-copper windings anikeza ukuhanjiswa kukagesi okuphezulu, okuholela ekulahlekelweni okuphansi kanye nokusebenza kahle okuphezulu uma kuqhathaniswa ne-aluminium. Ukumelana kwe-copper ekugqwaleni kanye namandla ayo okusebenza kunegalelo ekudeni nasekuthembekeni kwe-transformer.

Ama-winding e-aluminium, yize engadingi ugesi kakhulu kunethusi, anikeza izinzuzo eziningana ekwakhiweni kwe-transformer. Isisindo se-aluminium esilula sinciphisa isisindo sonke se-transformer, okwenza kube lula ukuphatha kanye nokuthuthwa kwayo. Ukumelana kwayo okuphezulu namandla okujikeleza okufushane kuthuthukisa ukuqina kwe-transformer, okwenza ingabi sengozini yokulimala ngenxa yamaphutha kagesi.

Ubukhulu nesisindo

Ubukhulu be-transformer engu-25 kVA buvame ukuba ngamasentimitha angu-24-30 ubude, amasentimitha angu-18-24 ububanzi, kanye namasentimitha angu-24-30 ukuphakama.

Isisindo sisukela kumakhilogremu angu-400-600, kuye ngezinto zokwakha kanye nezinye izingxenye ezifana namafin okupholisa noma amabakaki okufaka.
