Kuzungulira kwa Transformer Yomizidwa ndi Mafuta: Kuzindikira Kwaukadaulo ndi Mawonekedwe A Kapangidwe

Transformer Yomizidwa ndi Mafuta Ma windings ndi zinthu zofunika kwambiri mu makina ogawa magetsi, opangidwa kuti azitha kusamutsa mphamvu zamagetsi bwino pamene akuonetsetsa kuti mphamvu zake ndi zodalirika komanso zolimba. Pansipa pali kusanthula kwatsatanetsatane kwa kapangidwe kake, zipangizo zake, ndi mfundo zake zogwirira ntchito, zopangidwa kuchokera ku miyezo yamakampani ndi zidziwitso zaukadaulo.

Kutentha kwapamwamba kwa transformer yoviikidwa mu mafuta sikuloledwa kupitirira 95 ° C, nthawi zambiri sikuloledwa kupitirira 85 ° C, kusankha kwa transformer winding kwa zinthu zotenthetsera za kalasi A, kutentha kwakukulu kovomerezeka kwa zinthu zotenthetsera ndi 95 ~ 105 ° C, muzofunikira za kutentha kwa transformer ku China zimadalira kutentha kwa ntchito kwa 40 ° C monga muyezo, kuzunguliza kwa kutentha kwapakati kwa mpweya komwe kumaphatikizidwa mu 65 ° C, Kukwera kwa kutentha kwa mafuta apamwamba kupita ku gasi kumayikidwa molondola pa 55 ° C, kotero kuzunguliza komwe kuli pakati pa transformer kumaphatikizidwa pakukwera kwa kutentha kwa mafuta pa 10 ° C.

Ngati kutentha kwapamwamba kwa transformer ndi 85 ° C, kutentha kozungulira ndi 95 ° C; Ngati kutentha kwapamwamba ndi 95 ° C, kutentha kozungulira kwafika 105 ° C, komwe kwafika kutentha kovomerezeka kwa zinthu zotchingira zotchingira. Kutentha kwambiri kudzathandizira kukalamba kwa zinthu zotchingira zotchingira, kufulumizitsa kuwonongeka kwa mafuta a transformer, ndikuwononga moyo wautumiki wa Chosinthira Chogawas, ndipo ngakhale kumabweretsa ngozi zachitetezo.

Makina amphamvu oyendetsera mafuta opangidwa ndi thiransifoma yoziziritsidwa ndi mpweya, kutentha kwapamwamba kwa 75℃ kutentha kwa 35℃; Makina achilengedwe oyendetsera mafuta, chitetezo cha kutentha kwambiri, thiransifoma yoziziritsidwa ndi mpweya, kutentha kwapamwamba nthawi zambiri sikoyenera kupitirira 85 ° C, kutentha kwapamwamba kosapitirira 95 ° C sikupitirira 55 ° C, ngati mtengo wocheperako ukupitirira zofunikira, ayenera kupereka lipoti nthawi yomweyo pakupanga, pogwiritsa ntchito njira zotsutsana ndi malire a katundu.

1. Tanthauzo ndi Ntchito Yaikulu​

Ma winding a transformer oviikidwa mu mafuta amakhala ndi ma coil amkuwa kapena aluminiyamu ozungulira pakati pa chitsulo cha silicon choviikidwa. Ma winding awa amaviikidwa mokwanira mu mafuta oteteza kutentha, omwe amagwira ntchito ziwiri: ​kuteteza magetsi​ ndi ​kusamalira kutentha. Ma windings amasintha input ya high-voltage kukhala yotulutsa mphamvu yochepa (kapena mosemphanitsa) kudzera mu induction ya electromagnetic, zomwe zimathandiza kutumiza mphamvu motetezeka kudzera mu ma grid.

2. ​Kupanga Zinthu​

Zinthu Zoyendetsera Ntchito:

Mkuwa: Amagwiritsidwa ntchito kwambiri pa ma windings amphamvu chifukwa cha mphamvu zake zapamwamba komanso mphamvu zake zamakaniko. Ma windings otsika (≤500 kVA) nthawi zambiri amakhala ndi kapangidwe ka cylindrical kawiri, pomwe mphamvu zazikulu (≥630 kVA) amagwiritsa ntchito ma configurations a double-helix kapena quadruple-helix kuti akonze bwino kugawa kwa magetsi.

Aluminium: Nthawi zina imagwiritsidwa ntchito pazinthu zodula mtengo, ngakhale kuti sizogwira ntchito bwino ngati mkuwa.
Kuteteza kutentha:

Zipangizo zolimba kwambiri (monga ma epoxy resins, mapepala okhala ndi cellulose) zimalekanitsa ma windings kuchokera pakati ndi wina ndi mnzake.

Kuteteza zinthu zambiri kumateteza mafunde afupiafupi chifukwa cha kutentha kapena kusintha kwa makina.

3. Kapangidwe ka Kapangidwe

Kupanga kwa Winding:

Kupindika kwa Concentric (Cylindrical): Kofala m'ma transformer a magawo atatu, komwe ma windings otsika-voltage amayikidwa mkati mwa ma windings amphamvu kuti achepetse kutuluka kwa madzi.

Kupindika kwa Zilonda ndi Zilonda (Helical): Kumagwiritsidwa ntchito pakugwiritsa ntchito mphamvu yamagetsi yamphamvu, yokhala ndi zigawo zolumikizana kuti muchepetse kutayika kwa mphamvu yamagetsi ya eddy.

Kuphatikiza Koziziritsa:

Ma windings amaphatikiza ma ducts amafuta kuti azitha kutulutsa kutentha kudzera mu convection yachilengedwe kapena yokakamiza.

Matanki amafuta okhala ndi dzimbiri amalowa m'malo mwa zosungira zakale, zomwe zimathandiza kuti mafuta azitentha kwambiri komanso kuti azisunga malo otsekedwa.

4. Kukonza Magwiridwe Antchito​

Kapangidwe ka Kutayika Kochepa:

Ma Cores a Amorphous Alloy: Amachepetsa hysteresis ndi kutayika kwa eddy current (monga, ma transformer a S11-M series amapeza kutayika kotsika ndi 30% kuposa ma models akale)

Gulu Lolumikizira la Dyn11: Limachepetsa kusokonezeka kwa harmonic ndikukweza mphamvu mwa kuletsa mafunde a third-harmonic

Kukana kwa Dera Lalifupi:

Ma clamp opindika mwamphamvu ndi njira zopindika zozungulira zimathandiza kuti makina azikhala olimba panthawi yamavuto.

Zopumira za silika gel ndi Buchholz relay zimayang'anira kusayenda bwino kwa chinyezi ndi mafuta

5. Kugwiritsa Ntchito ndi Kusamalira

Zochitika Zokhudza Kutumiza Anthu:

Malo osungira magetsi m'mafakitale, ma gridi amagetsi m'mizinda, ndi makina amagetsi obwezerezedwanso (monga ma famu a mphepo).

Mphamvu zovomerezeka zimayambira pa 50 kVA mpaka 25,000 kVA, ndipo ma voltages ake ndi okwana 35 kV.

Machitidwe Osamalira:

Kusanthula mafuta nthawi zonse ndi kusanthula mpweya wosungunuka (DGA) kuti azindikire kuwonongeka kwa insulation.

Kujambula kutentha kuti mudziwe malo otentha omwe ali m'malo ozungulira.

6. Zatsopano mu Ukadaulo Wopanga Ma Winding

Kuika Vacuum: Kumachotsa matumba a mpweya panthawi yopanga, komanso kumawonjezera kulimba kwa kutentha kwa mpweya.

Kuwunika Mwanzeru: Masensa ogwiritsira ntchito IoT amatsata kutentha ndi kusinthasintha kwa katundu nthawi yeniyeni.
