Lub tshuab hluav taws xob tso cai rau koj nce qhov hluav taws xob vim yog qhov poob ntawm qhov tam sim no muaj zog, lossis rov qab hloov pauv. Hauv txhua kis, txoj cai ntawm kev txuag ntawm lub zog siv, tab sis qee qhov nws dhau los ua lub tshav kub. Yog li ntawd, qhov ua tau zoo ntawm kev hloov pauv, txawm hais tias feem ntau nyob ze rau kev sib koom ua ke, yog tsawg dua nws.

Cov Lus Qhia

Kauj ruam 1

Tus hloov hluav taws xob yog nyob ntawm ib qho tshwm sim hu ua electromagnetic induction. Thaum tus neeg xyuas pib kis rau qhov hloov chaw magnetic, ib qho hluav taws xob tshwm sim ntawm qhov kawg ntawm tus neeg xyuas pib no, uas sib raug rau thawj tus neeg raug hloov ntawm qhov hloov ntawm daim teb no. Yog li, thaum daim teb tsis tu ncua, tsis muaj hluav taws xob tshwm sim ntawm qhov kawg ntawm tus neeg xyuas pib. Cov pa hluav taws xob no yog tsawg heev, tab sis nws muaj peev xwm ua kom nce ntxiv. Ua li no, es tsis txhob coj tus coj ncaj, nws yog qhov txaus los siv lub coil uas muaj qhov xav tau ntau ntawm cov lem. Txij li thaum cov lem tau txuas nrog rau hauv series, cov voltages thoob plaws lawv tau suav txij. Yog li no, lwm yam sib txig sib luag, qhov ntsuas hluav taws xob yuav ntau dua ib qho los yog ib tus neeg coj tus cwj pwm ncaj qha nyob rau hauv tus naj npawb ntawm cov sij hawm sib raug raws li tus lej hloov.

Koj tuaj yeem tsim qhov kev hloov sib nqus sib nqus sib txawv. Piv txwv li, tig cov hlau nplaum ib sab ntawm coil yuav tsim lub tshuab hluav taws xob. Hauv kev hloov pauv, rau qhov no, lwm qhov kev siv winding, hu ua thawj qhov sib hloov, thiab qhov ntsuas hluav taws xob ntawm ib daim ntawv lossis lwm qhov tau thov rau nws. Ib qho hluav taws xob tshwm sim nyob rau hauv theem nrab winding, cov duab uas sib raug rau thawj tus neeg txuas ntawm lub voltage waveform nyob rau hauv thawj winding. Yog hais tias qhov hloov voltage rau thawj lub ntsuas hloov pauv hloov ntawm qhov tsis xws li, ntawm theem ob nws yuav hloov mus rau hauv cosine yam. Qhov sib pauv sib piv (tsis yog yuav tsum tau tsis meej pem nrog kev ua tau zoo) sib raug rau qhov sib piv ntawm tus naj npawb ntawm cov lem ntawm cov cua hloov. Nws tuaj yeem yog tus nqi tsawg lossis ntau dua ib tus. Hauv thawj kis, tus hloov pauv yuav rhais ruam zuj zus, nyob hauv theem ob - nqis los. Tus naj npawb ntawm lem ib volt (qhov thiaj li hu ua "tus naj npawb ntawm lem ib volt") yog tib yam rau tag nrho cov hloov hluav taws xob windings. Rau lub zog hloov pauv zaus, nws yog tsawg kawg 10, txwv tsis pub rau kev ua haujlwm poob qis thiab muaj cua sov nce ntxiv.

Lub sib nqus permeability ntawm huab cua yog qhov tsawg heev, yog li ntawd, qhov hloov pauv tsis tseem ceeb tsuas yog siv thaum ua haujlwm ntawm qhov muaj ntau zaus. Hauv kev tsim hluav taws xob ntau zaus, cov cores ua los ntawm cov paib steel them nrog dielectric txheej tau siv. Vim tias qhov no, cov paib tsis xeb hluav taws xob sib cais, thiab cov dej taws tsis tuaj yeem tshwm sim, uas tuaj yeem txo qhov ua tau zoo thiab nce cua sov. Hauv kev hloov pauv ntawm kev hloov cov khoom siv hluav taws xob ua haujlwm ntawm ntau zaus, cov cores no tsis siv tau, vim tias qhov tseem ceeb ntawm cov kab hluav taws xob tuaj yeem tshwm sim hauv txhua tus phaj, thiab cov sib nqus permeability ntau dhau. Ferrite cores raug siv nyob ntawm no - dielectrics nrog cov khoom muaj zog sib nqus.

Poob hauv lub tshuab hloov pauv, uas txo nws cov kev ua hauj lwm zoo, tshwm sim vim yog cov teeb meem ntawm lwm qhov chaw hloov pauv ntawm lub tshuab hluav taws xob los ntawm nws, cov dej ntws me me uas tseem tshwm sim hauv cov tub ntxhais txawm hais tias muaj kev ntsuas los tiv thaiv lawv, nrog rau muaj kev tawm tsam nyob rau hauv windings. Tag nrho cov kev cuam tshuam no, tsuas yog thawj zaug, ua rau muaj cua sov ntawm tus hloov pauv. Cov nquag tsis kam ntawm cov kab xaim yuav tsum tsis txaus siab piv rau sab hauv nruab nrog ntawm cov fais fab lossis thauj khoom. Yog li ntawd, ntau dua qhov tam sim no los ntawm qhov siv kab thiab qhov qis dua qhov hla thoob nws, cov hlau tuab yuav siv rau nws.
