VPI DRY TYPE TRANSFORMER

Kukula:

•Adavotera mphamvu: 112.5 kVA Kupyolera mu 15,000 kVA

•Mphamvu yamagetsi: 600V Kupyolera mu 35 kV

•Mphamvu yachiwiri: 120V Kupyolera mu 15 kV

Vacuum Pressure Impregnation (VPI) ndi njira yomwe chida chamagetsi chamagetsi kapena chozungulira chimamizidwa kwathunthu mu utomoni. Kupyolera mu kusakaniza kowuma ndi konyowa vacuum ndi kupanikizika, utomoni umalowetsedwa muzitsulo zonse zotsekemera. Kamodzi thermally kukonzedwa, ndi impregnated windings amakhala monolithic ndi homogenous dongosolo.

VPI dry type transformers ndiabwino pantchito zambiri zamafakitale ndi zamalonda. Zosinthazi zimapereka mphamvu zamakina komanso zazifupi, palibe ngozi yamoto kapena kuphulika, palibe zamadzimadzi zomwe zimatuluka, zolemera zochepa poyerekeza ndi mayunitsi a coil, otsika mtengo waumwini komanso zotsika mtengo zoyambira. Amagwiritsa ntchito UL yolembedwa 220°C kutchinjiriza dongosolo, mosasamala kanthu za kutentha. Kutsika kochepa, kukonza ndi kugwiritsira ntchito ndalama kumapangitsa otembenuza a VPI kukhala ndalama zolimba.

Zosintha za VPI sizimaphulika ndipo sizimawotcha moto ndipo sizifuna zotchingira, zotsekera, kapena zida zotsika mtengo zozimitsa moto.

Njira ya VPI

VPI thiransifoma makoyilo ndi vacuum kuthamanga wolowetsedwa mu kutentha kwambiri polyester varnish. Njirayi imaphatikizapo kumiza kwathunthu mu varnish pansi pa vacuum ndi kupanikizika ndi kuchiritsa koyendetsedwa pogwiritsa ntchito zida zoyendetsedwa ndi ndondomeko kuti zitsimikizire kusasinthasintha.

Mipiringidzo yomalizidwa imatetezedwa bwino ku chinyezi, dothi, ndi zowononga zambiri zamakampani. JIEZOU MPHAMVU's VPI zosinthira nthawi zambiri ndizoyenera kugwiritsidwa ntchito m'nyumba kapena kunja komwe anthu amagwira ntchito ndikupumira.

A 220℃Class UL Listed insulation system imagwiritsidwa ntchito pa JIEZOU POWER's VPI thiransifoma mosasamala kanthu za kutentha kwapadera. Dongosololi limatengera kutentha kwanthawi zonse kwa 150℃. Kutentha kosankha kumakwera 80℃ndi 115℃ndipo kuziziritsa kwa fani kumapangitsa kuti pakhale kuchuluka kwapang'onopang'ono.

Zosintha za VPI zimapereka kusinthika kwapangidwe ndipo zimagwiritsidwa ntchito nthawi zonse pakukweza mphamvu ndi mapangidwe obwezeretsanso.

Core Construction

Otembenuza a VPI amagwiritsa ntchito njira yolowera pomanga ma mitered core kuti awonetsetse kuti akugwira bwino ntchito komanso kumveka kochepa. Ma core joints amalola kusuntha koyenda bwino pakati pamiyendo yapakati ndi goli. Kumanga kwapang'onopang'ono kumapangitsanso kugwira ntchito kwa mgwirizano mwa kuchepetsa kuphatikizika kwa mgwirizano, zomwe zimachepetsa kutayika kwapakati komanso zosangalatsa zamakono.

Pakatikati idapangidwa ndikupangidwira kuti ipereke zotayika zotsika kwambiri kuchokera ku zotsatira za maginito hysteresis ndi mafunde a eddy. Njira zonse zomwe zingatheke zimachitidwa kuti tipewe kuyendayenda kwapafupi komanso kupewa zovuta zopindika.

Pakatikati pake amapangidwa kuchokera ku permeability kwambiri, kuzizira-kuzizira, chitsulo chokhazikika cha silicon. Kuchulukana kwa maginito kumasungidwa bwino pansi pa malo odzaza. Chitsulocho chimadulidwa molondola kuti chitsimikizire kuti chidzakhala chosalala komanso chopanda burr. Kuti zikhale zolimba komanso zothandizira, magoli apamwamba ndi apansi amamangidwa molimba ndi ziwalo zothandizira zitsulo. Zomangira mbale zimagwirizanitsa zokhoma pamwamba ndi pansi ndikupereka dongosolo lolimba lonyamulira.

Pachimake chomalizidwacho chimakutidwa ndi chosindikizira chosagwira corrosion chomwe chimapereka kulumikizana kwa lamination ndi chitetezo kumadera apakati kapena ovuta.

Coil Construction

Mapangidwe okhotakhota safunikira kufotokozedwa pokhapokha ngati pali zokonda za kasitomala. JIEZOU MPHAMVU imakonza zomangira zomangira zamagetsi ogwiritsira ntchito, mulingo woyambira, komanso kuchuluka kwaposachedwa kwapayekha.

Ngati ndi kotheka, ma transformer amapangidwa ndi chilonda chaching'ono chopindika chachiwiri ndi mawotchi oyambira a waya.

Kumangirira kozungulira kumatha kukhala kozungulira kapena kumakona anayi kudzera pa 2500 kVA pamakoyilo a VPI. Mamphepo pa ma VPI osinthira okhala ndi ma ratings opitilira 2500 kVA amakhala ozungulira.

JIEZOU MPHAMVU's otsika voteji VPI windings, kutchinjiriza kalasi 1.2 kV (600V) ndi m'munsimu, amavula ntchito makondakitala mapepala. Ntchito yomangayi imalola kufalitsa kwaulere mkati mwa axial m'lifupi mwa koyilo yomwe imachotsa mphamvu za axial zomwe zimapangidwira mumitundu ina ya ma windings pansi pazigawo zazifupi.

Koyilo yoyamba imadulidwa mwachindunji pa koyilo yachiwiri ndipo imasiyanitsidwa ndi chotchinga chotchinga. Aluminium conductors ndi ofanana ndi mkuwa woperekedwa ngati njira.
