Voltage regulation in transformers is qhov txawv ntawm qhov tsis muaj load voltage thiab tag nrho load voltage. Qhov no feem ntau yog qhia nyob rau hauv feem pua. Piv txwv li: Lub transformer xa 100 volts ntawm tsis muaj load thiab qhov voltage poob mus rau 95 volts ntawm tag nrho cov load, cov kev cai yuav yog 5%.
Vim li cas transformer ua haujlwm?
Lub hauv paus ntawm lub tshuab hloov pauv ua haujlwm rau coj txoj hauv kev ntawm cov hlau nplaum ntawm cov kauj ruam tseem ceeb thiab theem nrab kom tsis txhob siv lub zog khib nyiab. Thaum lub magnetic teb mus txog qhov thib ob kauj, nws yuam cov electrons nyob rau hauv nws txav, tsim ib tug hluav taws xob tam sim no ntawm electromotive force (EMF).
Dab tsi yog qhov tseem ceeb ntawm qhov hloov pauv?
Primary voltage yog qhov voltage siv rau cov terminals ntawm thawj winding ntawm transformer. Lub zog siv rau lub hauv paus yuav tsum yog nyob rau hauv daim ntawv ntawm ib tug hloov voltage uas tsim ib tug tas li hloov tam sim no nyob rau hauv thawj, vim tsuas yog ib tug hloov magnetic teb yuav tsim ib tug tam sim no nyob rau hauv lub thib ob.
transformer nce voltage li cas?
Transformers tsuas yog ua haujlwm nrog kev hloov tam sim no. Tias yog vim li cas nws yog qhov hloov pauv ntawm cov hlau nplaum tsim los ntawm thawj kauj uas induces voltagenyob rau hauv lub kauj thib ob. Txhawm rau tsim kom muaj qhov hloov pauv sib nqus, qhov hluav taws xob siv rau lub hauv paus kauj yuav tsum hloov tas li.
3 hom transformers yog dab tsi?
Nyobyog peb yam tseem ceeb ntawm voltage transformers (VT): electromagnetic, capacitor, thiab optical. Lub tshuab hluav taws xob hluav taws xob hluav taws xob yog lub tshuab hluav taws xob hloov hluav taws xob. Lub capacitor voltage transformer siv lub capacitance muaj peev xwm divider thiab yog siv nyob rau hauv high voltages vim tus nqi qis dua ib tug electromagnetic VT.

Uas niaj hnub nyob rau hauv lub datastage manager transformer theem?
DataStage Tus Thawj Saib Xyuas txhais cov khoom sau ua haujlwm hauv ib txwm ua. Muaj peb hom kev niaj hnub ua hauv DataStage, uas yog, kev tswj txoj haujlwm, ua ntej / tom qab subroutine, thiab hloov ua haujlwm. Dab tsi yog cov txheej txheem hauv DataStage?
Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau pom kev pom?
Txawm li cas los xij, corneal collagen cross-linking - cov txheej txheem qib siab tau pom zoo los ntawm US Food and Drug Administration (FDA) hauv xyoo 2016 - tuaj yeem txhim kho qhov pom kev hauv cov neeg mob txhua hnub nyoog. Corneal collagen cross-linking (CXL) tsis yog kho rau keratoconus, tab sis nws tuaj yeem pab tiv thaiv tus mob kom tsis txhob mob hnyav.
Nyob rau hauv ib lub neuron qhov twg voltage-gated calcium channel nyob?
Voltage-gated calcium channels (VGCCs), tseem hu ua voltage-dependent calcium channels (VDCCs), yog ib pab pawg ntawm voltage-gated ion channels pom nyob rau hauv daim nyias nyias ntawm cov hlwb excitable (xws li, cov leeg, glial hlwb, neurons, thiab lwm yam.
Leej twg detering nyob rau hauv tag nrho cov nyob ntsiag to nyob rau sab hnub poob pem hauv ntej?
Detering yog tus neeg ua liaj ua teb los ntawm Txhua Tus Neeg Tsis Txaus Siabntawm Sab Hnub Poob los ntawm Erich Maria Remarque. Nws muaj siab mos siab muag, tshwj xeeb tshaj yog thaum nws los txog rau nees. Nws muaj kev kub ntxhov loj heev thaum nws hnov cov nees quaj thiab txawm sim tua lawv kom kawg lawv txoj kev txom nyem.
Leej twg yog bennie nyob rau hauv lub raisin nyob rau hauv lub hnub?
Beneatha Younger ("Bennie") Mama tus ntxhais thiab W alter tus muam. Beneatha yog ib tug neeg txawj ntse. Nees nkaum xyoo, nws mus kawm ntawv qib siab thiab kawm tau ntawv zoo dua li lwm cov Tsev Neeg Hluas. Qee qhov ntawm nws tus kheej kev ntseeg thiab kev xav tau ua rau nws nyob deb ntawm niam txiv.
