Kev piav qhia
1.Core Feature
Lub hom phiaj tseem ceeb ntawm transformer yog hloov qhov voltage thiab tam sim no theem ntawm alternating tam sim no yam tsis hloov qhov zaus.
2. Lub hauv paus ntsiab lus ua haujlwm
(1) Cov tswv yim hloov tam sim noCov transformer yuav tsum siv alternating tam sim no. Cov kev taw qhia thiab qhov loj ntawm alternating tam sim no hloov pauv tsis tu ncua. Peb dhau qhov kev hloov AC mus rau hauv thawj kauj ntawm lub transformer.
(2) Tsim ib qho kev hloov pauv magnetic Raws li Oersted txoj cai, ib qho hluav taws xob tam sim no ntws los ntawm cov hlau tsim ib qho chaw sib nqus. Txij li thaum tam sim no nyob rau hauv thawj kauj ruam hloov tsis tu ncua, nws generates ib magnetic teb nyob rau hauv cov tub ntxhais uas nws lub zog thiab kev taw qhia yog tas li hloov.
(3) Sib nqus teb conduction los ntawm cov tub ntxhais The coils ntawm ib tug transformer feem ntau yog mob nyob ib ncig ntawm ib tug tub ntxhais ua los ntawm stacked silicon steel los xij. Cov tub ntxhais no tuaj yeem ua haujlwm tau zoo thiab mloog zoo rau qhov hloov pauv magnetic teb uas tsim los ntawm thawj kauj ruam uas yuav luag tsis muaj kev poob rau lub kauj thib ob.
(4) Sib nqus teb txiav los ntawm lub kauj kauj ruam thib ob Thaum qhov kev hloov pauv ntawm cov hlau nplaum no dhau los ntawm cov kauj ruam thib ob, qhov hloov pauv tsis tu ncua sib nqus ua haujlwm tau zoo ua rau cov xov hlau hauv cov kauj thib ob kom 'txiav' cov kab sib nqus flux.
(5) Induce ib tug tshiab voltage (electromagnetic induction) Raws li Faraday txoj cai ntawm electromagnetic induction, thaum lub magnetic flux los ntawm ib tug kaw Circuit Court hloov, ib tug induced electromotive quab yuam (voltage) yog generated nyob rau hauv lub Circuit Court. Yog li ntawd, ib qho kev hloov hluav taws xob yog induced hla ob qhov kawg ntawm lub kauj coil thib ob.
3.Txawm hais tias lub transformer yog "step-up" lossis "step-down" transformer nkaus xwb nyob ntawm qhov sib piv ntawm cov kauj ruam thib ob rau lub kauj kauj ruam thib ob.
Lawv ua raws li tus qauv yooj yim:
- Vp / Vs=Np / Ns
- Vp: Thawj kauj voltage (input voltage)
- Vs: Secondary coil voltage (tso zis voltage)
- Np: Tus naj npawb ntawm lem nyob rau hauv thawj kauj
- Ns: Tus naj npawb ntawm lem nyob rau hauv lub thib ob kauj
Nyob rau tib lub sijhawm, raws li txoj cai ntawm kev txuag hluav taws xob (tsis quav ntsej qhov poob qis), qhov kev hloov pauv ntawm qhov hluav taws xob thiab tam sim no yog qhov txawv: Vp × Ip ≈ Vs × Yog
- Ip: Thawj kauj tam sim no (input tam sim no)
- Yog: Secondary coil tam sim no (tso zis tam sim no)
4. Txheej txheem cej luam
Hauv cov ntsiab lus yooj yim, kev ua haujlwm ntawm lub tshuab hloov hluav taws xob yog lub zog hloov pauv ntawm 'hluav taws xob → sib nqus → hluav taws xob': Hloov tam sim no siv rau lub hauv paus kauj tsim ib qho kev hloov magnetic teb, uas yog ua los ntawm cov tub ntxhais thiab induces theem nrab kauj, yog li tsim ib tug tshiab alternating tam sim no. Los ntawm kev hloov pauv qhov sib piv ntawm ob lub coils, cov zis hluav taws xob tuaj yeem hloov kho tau yooj yim.
