Dab tsi yog qhov txawv ntawm AC thiab DC?

Hauv peb lub neej txhua hnub, peb yuav tsum siv hluav taws xob txhua hnub, thiab peb tsis tau ua tiav tam sim no, thaum muaj hluav taws xob ua haujlwm tam sim no, thaum muaj hluav taws xob ua haujlwm tau hloov tshiab tam sim no, yog li dab tsi Qhov sib txawv ntawm ob hom hluav taws xob?

Ncaj qha tam sim no

"Kev tam sim no ncaj qha", tseem hu ua "tam sim no yog ib yam ncaj qha tam sim no, yog qhov loj me thiab kev coj ua tsis hloov nrog lub sijhawm.
Hloov pauv tam sim no

Hloov pauv tam sim no (AC)yog tam sim no uas nws qhov kev sib tw hloov mus ib txhis, thiab yog hu ua lwm yam tam sim no lossis tsuas yog hloov tshiab vim tias tus nqi nruab nrab ntawm ib lub sijhawm tam sim no hauv ib lub voj voog yog xoom.
Cov kev taw qhia yog tib yam rau kev ncaj ncaj. Feem ntau cov nthwv dej yog sinusoidal. Hloov chaw tam sim no tuaj yeem hloov hluav taws xob. Txawm li cas los xij, muaj lwm cov chaw pov khoom uas tau ua tiav, xws li cov nthwv dej tsis thiab square vuag.

Sib txawv

1. Kev taw qhia: nyob rau hauv ncaj qha tam sim no, cov kev taw qhia ntawm tam sim no ib txwm ib txwm tseem nyob li qub, ntws hauv ib qho kev coj. Nyob rau hauv kev sib piv, cov kev taw qhia ntawm tam sim no nyob rau hauv lwm qhov kev hloov pauv tam sim no, hloov ntawm cov lus qhia zoo thiab tsis zoo.

2. Voltage hloov: Qhov voltage ntawm DC tseem tas mus li thiab tsis hloov zuj zus. Qhov voltage ntawm lwm qhov tam sim no (AC), ntawm qhov tod tes, yog Sinusoidal nyob rau lub sijhawm, thiab qhov ntau zaus yog 50 HZ.

3. Kev sib kis mus deb: DC muaj lub zog me me poob thaum muaj kev sib kis thiab tuaj yeem kis tau dhau mus ntev. Thaum lub zog hauv lub zog hauv kev ncua ntev ntev yuav muaj lub zog loj, yog li yuav tsum tau hloov kho thiab them nyiaj los ntawm tus hloov pauv.

4. Hom hluav taws xob muab: Cov roj teeb sib npaug rau cov roj teeb thiab cov roj hmab hlwb, thiab lwm yam Cov hluav taws xob tsim cov DC tam sim no. Thaum AC fais fab feem ntau yog tsim los ntawm cov nroj tsuag fais fab thiab muab los ntawm kev hloov pauv thiab kis cov kab rau kev ua lag luam hauv tsev thiab kev siv.

5. Thaj chaw ntawm daim ntawv thov: DC feem ntau siv hauv cov khoom siv hluav taws xob, hluav taws xob tsheb,Hnub ci lub nruab, etc. AC yog siv dav hauv tsev neeg daim ntawv thov. Hloov lwm yam tam sim no (AC) yog siv dav hauv tsev neeg hluav taws xob, kev lag luam ntau lawm, thiab lub hwj chim kis.

6. Tam sim no muaj zog: lub zog tam sim no ntawm AC tuaj yeem sib txawv hauv kev voj voog, thaum lub dc feem ntau nyob tas li. Qhov no txhais tau tias rau tib lub zog, lub zog ntawm AC yuav loj dua li DC.

7. Cov teebmeem thiab kev nyab xeeb: Vim tias cov kev hloov pauv ntawm kev taw qhia tam sim no, nws yuav ua rau hluav taws xob hluav taws xob, cuam tshuam thiab muaj peev xwm ua tau zoo. Cov teebmeem no yuav cuam tshuam rau cov khoom siv thiab kev noj qab haus huv nyob rau qee cov xwm txheej. Hauv kev sib piv, DC hluav taws xob tsis muaj cov teeb meem no thiab yog li no nyiam rau qee cov cuab yeej rhiab lossis cov kev siv tshwj xeeb.

8. Kis tau cov nyiaj poob: DC hluav taws xob tsis tshua muaj zog poob thaum kis tau ntev vim tias nws tsis cuam tshuam los ntawm cov kev tiv thaiv thiab kev tsis kam ntawm AC fais fab. Qhov no ua rau DC ntau npaum li cas nyob rau hauv kev ncua deb thiab kev hloov fais fab.

9. Cov Khoom Siv Ntaus: AC cov khoom siv (piv txwv li, cov tshuab pauv khoom, cov tshuab hluav taws xob, thiab lwm yam, thiab yog li nws tus nqi qis. DC khoom (piv txwv li,lub inverters, voltage regulators, thiab lwm yam), ntawm qhov tod tes, feem ntau yog kim dua. Txawm li cas los xij, nrog rau kev txhim kho DC thev naus laus zis, tus nqi ntawm DC cov khoom siv tau maj mam txo qis.
