1 Taw qhia hauv kev tsim qauv ntawmLub zog hloov hluav taws xob, rau kev yooj yim ntawm cov txhuas kev ua si, tus Tsov tus tw xaus ntawm ib theem chev tej zaum yuav tsis yooj yim rau cov txhuas tawm ntawm tib qho ntawm cov tub ntxhais. Txhawm rau kom paub meej seb puas muaj kev npaj ua qauv zoo li no, peb yuav tsum ua kom meej meej lub tswv yim tseem ceeb muaj feem nrog lub zog hloov hluav taws xob.
2 cov ntsiab lus yooj yim
Ua ntej sib tham txog hluav taws xob hloov ntawm lub kauj, peb yuav tsum xub tham luv luv txog lub tswv yim ntawm cov kauj, vim tias cov no yog ob lub ntsiab lus uas mus ua ke.
Cov duab hloov pauv mus rau lub cev tig los ua los ntawm cov kauj ruam ntawm cov txheej txheem ua si, thiab qee cov tshuab winding nrog suav cov haujlwm muaj txiaj ntsig zoo tus nqi no. Piv txwv li, yog tias ib coil muaj 20 lub zog, xaim hluav taws xob pwm rau 10 pads, thiab nws tseem muaj hluav taws xob yog tsis paub.
Hluav taws xob hloov ntawm lub coil xa mus rau tus naj npawb ntawm cov lem uas tuaj yeem sib nqus nrog lub sib nqus uas tuaj yeem tsim cov hlau nplaum flux ib ncig ntawm cov hlau hauv cov tub ntxhais. Txhua tus lej ntawm cov lem uas tsis tuaj yeem tsim lub zog hluav taws xob tsis tuaj yeem hu ua hluav taws xob hloov.
Yog li no, cov duab hloov pauv ntawm txhua tus coil yuav tsum tau hais meej rau kev tsim qauv tsim qauv, tsis yog hluav taws xob hloov. Vim tias txawm hais tias cov kauj nrog tib cov duab geometric ib txwm muaj nyob ntawm cov haujlwm sib txawv ntawm tib txoj haujlwm sib txawv, lawv cov hluav taws xob hloov pauv yuav txawv. Yog tias hluav taws xob hloov ntawm lub kauj yog cim ntawm kev kos duab kos, nws tsis tuaj yeem txheeb xyuas ncaj qha.
Rau qhov tsim ntawm lub zog hloov pauv, hluav taws xob hloov thiab cov hluav taws xob tig yog ob lub tswv yim tseem ceeb uas yuav tsum tau ua kom meej meej.
Qhov tig tau muaj peev xwm, kev sib zog hluav taws xob, amperance-tig thiab impedance voltage ntawm lub zog hloov pauv yuav tsum tau xam raws li hluav taws xob hloov ntawm lub kauj; Thaum lub dc tsis kam thiab eddy tam sim no poob ntawm cov kauj yuav tsum tau suav raws li cov duab geometric ntawm cov kauj.
3 Cov ntsiab cai yooj yim
Raws li kev ua raws li Faraday Txoj Cai Induction, thaum sib nqus flux dhau los ntawm lub voj, tsis hais lub voj, tsis hais txog lub voj kaw lossis tsis yog. Qhov ntau ntawm cov inducteromotive quab yuam yog proportional rau tus nqi ntawm kev hloov ntawm cov sib nqus flux. Yog li ntawd, los ntawm qee qhov kev xav, tus naj npawb ntawm hluav taws xob hloov ntawm lub kauj yog tus naj npawb ntawm vector puv ntxiv lossis rho tawm cov kev suav yuav tsum ua raws li cov kev ua haujlwm vector.
4 TAWG
Nyob rau hauv cov xwm txheej ntawm qee yam kev nthuav dav sab nraud thiab hluav taws xob muab ntau zaus, lub ntsiab sib nqus flux ntawm lub transformer yog inventely proortional rau cov hluav taws xob hloov ntawm lub kauj. Yog li ntawd, ib zaug ntawm cov hluav taws xob hloov ntawm peb-theem chev yog tsis sib luag, cov hauv qab no yuav ua rau muaj txiaj ntsig:
1) Unbalanced peb-theem lub ntsiab sib nqus cov teeb meem ntawm peb-theem tsib-kem lossis ib-theem hloov pauv yuav yog qhov loj dua li ntawm kev ua kom dawb huv. Ib qho ntxiv, rau cov hloov pauv kauj ruam, vim tias cov hluav taws xob hloov ntawm peb-ntu ntawm cov hluav taws xob uas tsis muaj sib npaug, txawm tias tsis muaj qhov xwm txheej ntawm lub ntsiab tsis sib nqus.
2) Tshaj lub voltage piv cov xwm txheej no yuav tshwm sim thaum tus naj npawb ntawm lem ntawm lub kauj ntawm lub zog transformer nws tus kheej yog qhov me me. Cov nqi tshwj xeeb ntawm cov hluav taws xob piv tau tuaj yeem suav los ntawm xa mus rau cov qauv saum toj no.
3) Core sancation tshwm sim tshwj xeeb tshaj yog rau peb-theem kev hloov pauv, yog tias muaj kev sib nqus ntawm tus quab yuam ua ke Txawm li cas los xij, qhov tshwm sim no yuav tsis raug nrhiav pom thaum lub sijhawm tsis muaj kev thauj mus los, vim tias cov hluav taws xob ntau feem ntau yog qhib Circuit Court nyob rau lub sijhawm no.
Tsis tas li ntawd, qee kis, tus naj npawb ntawm hluav taws xob hloov ntawm cov kauj yuav tsum muaj sib npaug. Piv txwv li, rau ib qho hloov pauv ib leeg nrog ob kab hauv cov kab hluav taws xob tau sib npaug, nws yuav ua rau muaj sib npaug tag nrho, nws yuav ua rau muaj kev sib npaug nrog kev poob haujlwm tam sim no.
Yog li ntawd, nyob rau theem tsim, qhov xwm txheej ntawm kev tsis sib xyaw hluav taws xob hloov ntawm peb-theem chev yuav tsum tau zam kom ntau li ntau tau. Txawm hais tias lub txim uas tsis muaj hluav taws xob hloov ntawm peb-theem chev tuaj yeem lees txais los ntawm cov kws tsim qauv engineering yuav tsum tau txheeb xyuas ib rooj plaub, thiab tsis tuaj yeem txheeb xyuas.
