Daim ntawv qhia ua tiav rau Lub Hwj Chim Hloov Pauv Hloov Pauv: Kev faib tawm & Nomenclature

Fais fab transformers yog cov cuab yeej tseem ceeb ntawm lub zog xa hluav taws xob thiab kev xa tawm, nrog ntau hom kev ua kom haum rau cov xwm txheej sib txawv, qib voltage, thiab kev ua haujlwm. Cov lus qhia no piav qhia txog kev faib tawm ntawm cov hluav taws xob hloov hluav taws xob los ntawm lub hom phiaj, winding configuration, qauv, txoj kev txias, thiab lub ntsiab lus ntawm transformer qauv nomenclature, muab ib tug kev siv rau lub ntiaj teb no buyers, engineers, thiab fais fab system tswv.

1. Kev faib tawm los ntawm Daim Ntawv Thov

Transformers yog categorized raws li lawv cov haujlwm tseem ceeb hauv lub zog hluav taws xob:

Kauj ruam -Up Transformer: Siv nyob rau hauv cov nroj tsuag fais fab los txhawb qhov hluav taws xob ntev - kis tau tus mob nyob deb.

Kauj Ruam -Kub Transformer: Siv nyob rau hauv kev siv hluav taws xob substations los txo cov kab hluav taws xob siab rau kev faib khoom.

Kev faib tawm Transformer: Siv los xa hluav taws xob ncaj qha mus rau qhov kawg - cov neeg siv (chaw nyob, kev lag luam, kev lag luam).

Chaw nres tsheb Service Transformer (Power Plant): Cov khoom siv hluav taws xob pabcuam rau kev ua haujlwm sab hauv ntawm cov chaw tsim hluav taws xob.

Chaw nres tsheb Service Transformer (Substation): Muab lub zog pabcuam rau kev ua haujlwm sab hauv ntawm substations.

Hloov Transformer: Siv nyob rau hauv HVDC (High-Voltage Direct Current) kis tau tus mob, nrog ib sab txuas nrog AC fais fab thiab lwm qhov rau converter li qub.

Rectifier transformer: Siv nyob rau hauv thermal fais fab nroj tsuag los muab lub zog rau electrostatic precipitators (ESP).

2. Kev faib tawm los ntawm Winding Configuration

Transformers yog pawg los ntawm tus lej thiab cov qauv ntawm lawv cov windings:

Ob npaug -Winding Transformer: Hom feem ntau, siv rau kauj ruam -nce, kauj ruam- nqes, thiab chaw nres tsheb kev pabcuam.

Peb -Winding Transformer: Siv rau kauj ruam- nqis, kev sib txuas, thiab lwm yam kev siv uas xav tau peb theem voltage.

Autotransformer: Siv rau kauj ruam- nqes, kev sib txuas, thiab kev tswj qhov hluav taws xob hauv kab hluav taws xob.

Split-Winding Transformer: Muaj nyob rau hauv axial-split thiab radial-split designs, feem ntau yog siv rau kev pabcuam chaw nres tsheb thiab kev siv fais fab thaub qab.

3. Kev faib tawm los ntawm Cov Qauv

Transformers raug cais los ntawm lawv cov theem thiab cov qauv sib dhos:

Tib -Phase Transformer: Siv rau siab -voltage transformers nyob rau hauv 330 ~ 1000kV ntau yam.

Peb -Phase Transformer: Hom qauv rau kev faib hluav taws xob, siv rau kev hloov pauv hauv 10 ~ 500kV ntau yam.

Modular / Sib xyaw Transformer: Lub tshuab hloov pauv tau muab faib ua ntau yam rau kev thauj mus los, tom qab ntawd sib sau ua ke ntawm -site, zoo tagnrho rau thaj chaw deb uas muaj kev thauj mus los tsawg.

4. Kev faib tawm los ntawm txoj kev txias

Txoj kev txias txias yog ib qho tseem ceeb ntawm kev txiav txim siab txog kev siv transformer thiab kev ua haujlwm:

Roj-Immersed Transformer: Feem ntau siv hom, haum rau transformers nyob rau hauv lub 10 ~ 1000kV ntau yam, nrog ntxhia roj raws li cov cua txias thiab insulating nruab nrab.

Qhuav -Hom Transformer: Cua-cooled, tsis yog{1}}flammable, haum rau sab hauv tsev siv nyob rau hauv lub 10 ~ 110kV ntau yam, zoo tagnrho rau cov tsev lag luam thiab hauv nroog substations.

SF6 Gas-Insulated Transformer: Tam sim no siv rau 110kV transformers, nrog sulfur hexafluoride roj raws li lub rwb thaiv tsev thiab cua txias nruab nrab, haum rau ib puag ncig tshwj xeeb.

5. Fais fab Transformer Model Nomenclature

Tus qauv ntawm lub zog hloov hluav taws xob yog tus qauv code uas txhais tau tias nws cov ntsiab lus tseem ceeb, qauv, thiab cov yam ntxwv. Hauv qab no yog lub ntsiab lus ntawm cov tsiaj ntawv nyob rau hauv Suav transformer qauv, dav siv nyob rau hauv lub ntiaj teb no kev lag luam rau Suav - tsim transformers:

5.1 Lub ntsiab lus ntawm cov ntawv hauv Transformer qauv

表格

Nco tseg: Copper windings thiab ob -winding designs tsis tas yuav muaj cov cim ntxiv hauv tus qauv.

5.2 Piv txwv ntawm Tus Qauv Txhais Lus

Piv txwv li, tus qauvSCB10-1000/10tuaj yeem txhais tau tias:

S: Peb-phase

C: Epoxy resin cam khwb cia qhuav - hom

B: Ntawv nyiaj winding

10: Tsim series

1000: Rated muaj peev xwm 1000kVA

Vim Li Cas Phau Ntawv Qhia no tseem ceeb rau koj txoj kev lag luam

Rau cov neeg yuav khoom thoob ntiaj teb, cov neeg siv hluav taws xob sib koom ua ke, thiab cov neeg cog lus hluav taws xob, kev faib cov khoom siv hluav taws xob thiab cov nomenclature xyuas kom meej:

Kev xaiv kom raug ntawm transformers rau cov phiaj xwm tshwj xeeb thiab cov ntawv thov
