Cov neeg tsim qauv tsim lub chaw tsim hluav taws xob tau mob siab txhawm rau txo qhov tseem ceeb lossis tshem tawm txhua qhov tsis txaus siab uas mus nrog kev ua haujlwm ntawm cov cuab yeej ntawd. Tab sis tseem, qee qhov tsis zoo yuav tsis raug tshem tawm tag nrho. Ib qho ntawm lawv yog lub suab nrov thiab hum ntawm qhov hloov pauv.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm kev hloov pauv
Lub tshuab hloov hluav taws xob yog cov cuab yeej siv hluav taws xob uas hloov cov hluav taws xob hluav taws xob los ntawm qhov chaw nyob ruaj khov mus rau lwm lub coil ntawm tib lub hom, uas tsis txuas nrog thawj zaug hauv txoj kev siv hluav taws xob. Lub zog hluav taws xob kis tau los ntawm kev sib nqus sib nqus sib txuas ntawm cov kab hlau thiab txuas ntxiv hloov nws qhov kev taw qhia thiab qhov loj ("Elementary hluav taws xob engineering rau xov tooj cua amateurs", AD Batrakov, 1950).
Thaum muaj kev hloov tam sim no ntws los ntawm tus thawj kauj, nws tsim qhov sib nqus. Cov kab hluav taws xob muaj zog ntawm daim teb no nkag mus rau tsis yog thawj zaug nkaus xwb, tabsis kuj tseem thib ob qhov hloov ntawm lub qhov hloov pauv. Cov kab muaj kev ruaj ntseg kaw ib puag ncig ntawm cov neeg xyuas pib, uas tau sib nqus dua li txuas hluav taws xob.
Qib qhov kev sib txuas ntawm ob lub tsho yog txiav txim siab los ntawm qhov kev ncua deb ntawm lawv.
Thaum qhov xaus ntawm lub kauj vuam txuas nrog cov neeg siv hluav taws xob, hluav taws xob hluav taws xob tshwm sim hauv Circuit Court, thiab cov cuab yeej hauv hauv Circuit Court tau txais lub zog. Vim yog qhov sib txawv hauv cov xov tooj ntawm cov lem ntawm thawj thiab theem ob txheej, txhua qhov yuav tsum muaj voltage tuaj yeem tau ntawm qhov tawm. Qhov no yog suav hais tias yog cov khoom siv tseem ceeb ntawm cov hloov pauv twg.
Vim li cas cov transformer ua suab nrov
Lub zog hluav taws xob siab tam sim no lub tshuab hluav taws xob yog ib qho ntawm cov teeb meem suab nrov uas feem ntau tau hnov nyob hauv chaw ib puag ncig. Lub suab nrov uas zoo li lub suab quaj yog feem ntau tshwm sim los ntawm lub zog kev co ntawm cov yam ntxwv ntawm lub cuab yeej, uas ua kom nrov nrov los ntawm kev tshwm sim resonance.
Vim li cas kev vibration tshwm sim? Feem ntau, nws yog vim muaj qhov tshwm sim hu ua magnetostriction. Cov nyhuv no yog ib hom deformation ntawm cov siv lead ua lub ntsej muag uas ua kom muaj cov khoom sib nqus. Magnetostriction tshwm sim thaum lub sij hawm magnetization ntawm cov yam ntxwv, thaum lub sij hawm induction nce, ua rau cov khoom siv lub muaju ua haujlwm hloov.
Lub muaju pib tig, qhov tshwm sim ntawm qhov uas txoj kab qhov ntev ntawm cov hlau hloov nrog lub ntu siab. Nws yog qhov tshwm sim no uas ua rau kev vibration thiab suab nrov.
Lwm qhov laj thawj rau lub buzzing ntawm qhov hloov pauv yog qhov pom ntawm cov lus sib nqus. Cov nyhuv no yog tshwj xeeb tshaj yog hais ntawm cov pob qij txha ntawm cov khoom siv ntaus. Cov nplooj ntawv ib leeg ntawm cov tub ntxhais hloov hluav taws xob tau khoov los ntawm cov kab sib hloov pauv no, ua rau muaj suab nrov thiab nce ntxiv cov txiaj ntsig magnetostrictive. Lub tshuab pa pib hloov mus rau lub siab.
Lub suab nrov ntawm cov hloov pauv ncaj qha nyob ntawm lawv qhov ntev thiab qhov hnyav. Qhov ntev ntawm tus pas nrig ntawm lub sib nqus hlau, nrog rau qhov zoo ntawm cov hlau, tuaj yeem cuam tshuam lub suab zog. Kev nkag ntawm lub system mus rau resonance lossis kev puas tsuaj rau lub kauj hloov pauv tau tuaj yeem ua kom nrov nrov ntawm kev hloov ua haujlwm.
