Taw qhia, Txoj Cai thiab Kev faib tawm ntawm Peb Theem Fais Fab Transformers
Taw qhia rau peb theem fais fab transformers
Lub transformer yog ib qho cuab yeej siv lub hauv paus ntsiab lus ntawm electromagnetic induction los hloov AC voltage. Nws lub ntsiab Cheebtsam yog thawj kauj, theem nrab kauj thiab hlau core.
Lub luag haujlwm tseem ceeb ntawm lub transformer yog: kev hloov hluav taws xob, kev hloov pauv tam sim no, kev hloov pauv impedance, kev sib cais, kev tswj hluav taws xob (magnetic saturation transformer), thiab lwm yam. Raws li kev siv, nws tuaj yeem muab faib ua lub zog transformers thiab tshwj xeeb transformers.
Peb theem fais fab transformers ua haujlwm li cas
Transformer yog ib yam khoom siv los hloov hluav taws xob hloov pauv, hloov tam sim no thiab impedance. Thaum alternating tam sim no dhau los ntawm lub hauv paus kauj ntawm lub transformer, ib tug alternating magnetic flux yog generated nyob rau hauv lub hlau core (los yog magnetic core), thiab ib tug voltage (los yog tam sim no) yog induced nyob rau hauv lub thib ob kauj.
Nws muaj ib tug transformer core (los yog magnetic core) thiab ib kauj. Cov coils muaj ob los yog ntau tshaj windings, qhov twg cov winding txuas nrog lub hwj chim qhov chaw hu ua thawj kauj thiab lwm windings yog hu ua theem nrab kauj.
Lub ntsiab kev faib tawm ntawm peb theem fais fab transformers
Common transformers tuaj yeem muab faib ua pawg hauv qab no:
Raws li tus naj npawb ntawm theem:
1) Ib-theem transformer: siv rau ib-theem load thiab peb-theem transformer pawg.
2) Peb-theem transformer: siv rau kev nce thiab nqis ntawm peb theem system.
Raws li kev ua kom txias:
1) Cov tshuab ziab khaub ncaws qhuav: cia siab rau huab cua convection rau ntuj txias lossis kiv cua txias, thiab feem ntau yog siv rau cov khoom siv hluav taws xob me me xws li cov tsev siab, cov chaw nres tsheb ceev, teeb pom kev zoo hauv zos, thiab hluav taws xob circuits.
2) Roj-immersed transformer: cia siab rau roj raws li qhov nruab nrab cua txias, xws li roj-immersed nws tus kheej-txias, roj-immersed cua txias, roj-immersed txias, yuam cov roj ncig, thiab lwm yam.
Nyob ntawm daim ntawv thov:
1) Fais fab transformer: siv rau voltage nce thiab poob ntawm lub hwj chim kis tau tus mob thiab tis system.
2) Transformers: xws li voltage transformers, tam sim no transformers, ntsuas ntsuas, relay tiv thaiv pab kiag li lawm, thiab lwm yam.
3) Test transformer: Nws tuaj yeem tsim hluav taws xob siab thiab ua qhov ntsuas hluav taws xob siab ntawm cov khoom siv hluav taws xob.
4) Cov transformers tshwj xeeb: xws li lub cub tawg transformers, rectifier transformers, voltage regulating transformers, capacitor transformers, theem-hloov transformers, thiab lwm yam.
Raws li daim ntawv winding:
1) Ob chav winding transformer: siv los txuas ob theem voltage hauv lub zog hluav taws xob.
2) Peb-winding transformer: feem ntau siv nyob rau hauv substations nyob rau hauv lub hwj chim system cheeb tsam, txuas peb voltage theem.
3) Autotransformer: siv los txuas cov tshuab hluav taws xob sib txawv. Nws kuj tseem siv tau los ua ib qho kev hloov pauv ib txwm los lossis theem-down transformer.
Los ntawm peb theem fais fab transformer hlau core daim ntawv:
1) Hlau tub ntxhais transformer: high voltage hwj chim transformer.
2) Amorphous alloy transformer: Amorphous alloy hlau core transformer yog ib hom tshiab ntawm cov khoom siv hlau nplaum, thiab qhov tsis muaj load tam sim no raug txo los ntawm 80 feem pua. Nws yog ib qho kev faib hluav taws xob nrog lub zog txuag hluav taws xob zoo tagnrho, tshwj xeeb tshaj yog tsim rau cov kab hluav taws xob nyob deb nroog thiab tsim cov cheeb tsam nrog cov nqi qis.
3) Plhaub hom transformers: tshwj xeeb transformers nrog siab tam sim no, xws li hluav taws xob rauv transformers, vuam transformers; los yog fais fab transformers rau cov twj siv hluav taws xob, TV, xov tooj cua, thiab lwm yam.
