Lub tshuab hluav taws xob faib hluav taws xob yog dab tsi?
Lub tshuab hluav taws xob faib hluav taws xob yog ib qho khoom siv hluav taws xob uas siv tau los hloov qhov hluav taws xob hloov hluav taws xob ntawm qee tus nqi mus rau qhov hloov hluav taws xob ntawm lwm tus nqi ntawm tib zaus, thiab tuaj yeem hloov tus nqi ntawm qhov hloov pauv tam sim no, hloov qhov impedance lossis hloov pauv. theem.
Lub ntsiab lus ntawm hluav taws xob faib transformer
Lub tshuab fais fab xav xa hluav taws xob hluav taws xob ntawm P=3UIcosφ mus rau thaj chaw uas siv hluav taws xob. Thaum P thiab cosφ yog ib qho nqi, yog tias qhov hluav taws xob siv ntau dua, qhov tam sim no nyob rau hauv cov kab sib txuas yog me dua, yog li qhov poob ntawm cov kab sib txuas tuaj yeem raug txo. Txuag cov khoom siv hluav taws xob. Yog li ntawd, nws yog qhov kev lag luam tshaj plaws los siv cov hluav taws xob siab rau kev xa hluav taws xob mus ntev.
Tam sim no, qhov hluav taws xob ntawm AC kis tau tus mob hauv kuv lub teb chaws tau mus txog qhov siab tshaj plaws ntawm 500kV. Xws li qhov hluav taws xob siab tsis tso cai ncaj qha los ntawm lub tshuab hluav taws xob, tsis hais los ntawm kev ua haujlwm nyab xeeb ntawm lub tshuab hluav taws xob lossis los ntawm cov nqi tsim khoom. Qhov tso zis hluav taws xob ntawm lub tshuab hluav taws xob feem ntau yog 3.15kV, 6.3kV, 10.5kV, 15.75kV, thiab lwm yam. Yog li ntawd, yuav tsum siv lub tshuab hluav taws xob nce qib kom nce qhov voltage ua ntej kev sib kis mus ntev.
Tom qab lub zog hluav taws xob xa mus rau thaj chaw siv hluav taws xob, txhawm rau ua kom tau raws li qhov yuav tsum tau muaj ntawm cov khoom siv hluav taws xob, nws yog ib qho tsim nyog yuav tsum siv cov khoom siv hluav taws xob hauv txhua theem ntawm cov khoom siv hluav taws xob kom txo tau qhov hluav taws xob mus rau qhov ntsuas hluav taws xob uas xav tau los ntawm ntau yam khoom siv hluav taws xob.
Hais txog kev siv hluav taws xob, qhov hluav taws xob xav tau los ntawm cov khoom siv hluav taws xob feem ntau yog 380V, 220V lossis 36V, thiab ob peb lub cev muaj zog kuj siv 3kV, 6kV, thiab lwm yam.
Hluav taws xob faib Transformer Classification
Raws li lawv cov kev siv sib txawv, muaj cov fais fab transformers, fais fab transformers, voltage regulating transformers, instrument transformers, thiab cais transformers. Raws li cov qauv, nws muab faib ua ob-winding transformer, peb-winding transformer, multi-winding transformer thiab autotransformer. Raws li cov qauv tseem ceeb, nws tau muab faib ua plhaub hom transformers thiab core-type transformers. Raws li tus naj npawb ntawm theem, nws tau muab faib ua ib-theem transformers, peb-theem transformers thiab multi-theem transformers. Txawm hais tias muaj ntau hom kev hloov pauv, cov hauv paus ntsiab lus thiab cov qauv yog tib yam.
Tus Qauv Txheej Txheem Ntawm Cov Hluav Taws Xob Fais Fais Fab Transformer
(1) Hlau tub ntxhais
Lub transformer yog tsim los ntawm ob los yog ntau dua coils (windings) teem rau ntawm ib tug kaw hlau tub ntxhais,
Cov tub ntxhais thiab cov kauj yog cov khoom tseem ceeb ntawm transformer. Cov tub ntxhais hlau ua cov hlau nplaum hluav taws xob xav tau rau electromagnetic induction. Txhawm rau txo qhov poob tam sim no los ntawm kev hloov pauv ntawm cov hlau nplaum sib nqus, cov tub ntxhais hlau ntawm lub tshuab hloov pauv yuav tsum tau muab tso rau hauv cov ntawv silicon steel nrog lub thickness ntawm {{0}}.35 txog 0.5 hli. Cov nplooj ntawv yog sib cais los ntawm insulating xim. Cov tub ntxhais hlau tau muab faib ua ob hom: hom tub ntxhais thiab hom qhua.
(2) Coil
Lub coil txuas nrog lub transformer thiab lub hwj huam mov yog hu ua thawj winding (los yog thawj sab, los yog thawj winding), thiab nws cov xov tooj ntawm lem yog N 1, thiab lub kauj txuas nrog lub load yog hu ua lub thib ob winding (los yog sab thib ob, los yog theem nrab winding), thiab tus naj npawb ntawm lem yog N 2. Cov windings thiab windings thiab windings thiab cov tub ntxhais yog insulated ntawm ib leeg.
Transformers yog siv nyob rau hauv yuav luag tag nrho cov khoom siv hluav taws xob. Nws txoj ntsiab cai yog yooj yim, tab sis cov txheej txheem winding ntawm transformers yuav muaj qhov sib txawv raws li kev siv sib txawv (siv txawv). Lub zog ntawm lub transformer mas muaj xws li: voltage transformation; impedance transformation; muab cais nyob ib leeg.
