Ib zaug, Edison, uas yog tus neeg tsim khoom loj tshaj plaws hauv cov phau ntawv, yeej ib txwm yog ib tus neeg tuaj xyuas tsis tu ncua hauv cov ntsiab lus ntawm thawj

thiab cov menyuam kawm ntawv theem nrab.Tesla, ntawm qhov tod tes, ib txwm muaj lub ntsej muag tsis meej, thiab nws tsuas yog nyob hauv tsev kawm theem siab xwb

nws tau ntsib nrog lub tsev uas muaj npe tom qab nws hauv chav kawm physics.

Tab sis nrog kev nthuav dav hauv Is Taws Nem, Edison tau dhau los ua neeg phem ntau dua, thiab Tesla tau dhau los ua neeg tsis paub

tus kws tshawb fawb ntawm par nrog Einstein hauv lub siab ntawm ntau tus neeg.Lawv qhov kev tsis txaus siab kuj dhau los ua kev hais lus ntawm txoj kev.

Niaj hnub no peb yuav pib nrog cov hluav taws xob tam sim no ua tsov ua rog uas tawg ntawm ob.Peb yuav tsis tham txog kev lag luam lossis tib neeg

lub siab, tab sis tsuas yog tham txog cov ntsiab lus zoo tib yam thiab nthuav dav los ntawm cov ntsiab lus kev.

Raws li peb txhua tus paub, hauv kev ua tsov rog tam sim no ntawm Tesla thiab Edison, Edison tus kheej tau dhau Tesla, tab sis thaum kawg

ua tsis tau tejyam technically, thiab alternating tam sim no los ua tus overlord ntawm lub hwj chim system.Tam sim no cov me nyuam paub qhov ntawd

AC fais fab siv hauv tsev, yog vim li cas Edison thiaj xaiv DC fais fab?Yuav ua li cas AC fais fab mov system sawv cev

los ntawm Tesla tuav DC?

Ua ntej tham txog cov teeb meem no, peb yuav tsum xub ua kom pom tseeb tias Tesla tsis yog tus tsim ntawm kev hloov tam sim no.Faraday

paub txog cov txheej txheem ntawm kev tsim hluav taws xob hloov pauv thaum nws kawm txog qhov tshwm sim ntawm electromagnetic induction hauv 1831,

ua ntej Tesla yug los.Thaum lub sij hawm Tesla nyob rau hauv nws cov hluas, cov alternators loj tau nyob ib ncig ntawm.

Qhov tseeb, Tesla tau ua dab tsi yog ze rau Watt, uas yog txhawm rau txhim kho lub tshuab hloov pauv kom nws haum rau qhov loj.

AC zog systems.Qhov no kuj yog ib qho ntawm cov yam tseem ceeb uas ua rau muaj yeej ntawm AC system hauv kev ua tsov rog tam sim no.Ib yam li ntawd,

Edison tsis yog tus tsim khoom ntawm cov tshuab hluav taws xob tam sim no thiab ncaj qha tam sim no, tab sis nws kuj tau ua lub luag haujlwm tseem ceeb hauv

kev txhawb nqa ncaj qha tam sim no.

Yog li ntawd, nws tsis yog ib qho kev tsov rog ntawm Tesla thiab Edison vim nws yog tsov rog ntawm ob lub tshuab hluav taws xob thiab kev lag luam.

pab pawg tom qab lawv.

PS: Hauv cov txheej txheem ntawm kev tshuaj xyuas cov ntaub ntawv, kuv pom tias qee tus neeg hais tias Raday tau tsim lub ntiaj teb thawj qhov hloov pauv -

tusdisc generator.Qhov tseeb, cov lus no tsis yog lawm.Nws tuaj yeem pom los ntawm daim duab schematic uas lub tshuab hluav taws xob disc yog a

DC lub tshuab hluav taws xob.

Vim li cas Edison xaiv qhov tam sim no

Lub zog hluav taws xob tuaj yeem muab faib ua peb ntu: hluav taws xob tsim hluav taws xob (generator) - hluav taws xob xa hluav taws xob (distribution)

(transformers,kab, keyboards, thiab lwm yam) - siv hluav taws xob (ntau yam khoom siv hluav taws xob).

Hauv Edison lub sijhawm (1980s), DC lub zog hluav taws xob muaj lub tshuab hluav taws xob loj DC rau kev tsim hluav taws xob, thiab tsis xav tau lub tshuab hloov pauv.

raukev xa xov hluav taws xob, tsuav yog cov xov hlau tau teeb tsa.

Raws li kev thauj khoom, lub sijhawm ntawd txhua tus neeg feem ntau siv hluav taws xob rau ob txoj haujlwm, teeb pom kev zoo thiab tsav tsheb.Rau incandescent teeb

siv rau teeb pom kev zoo,tsuav yog qhov voltage ruaj khov, nws tsis muaj teeb meem seb nws yog DC lossis AC.Raws li rau motors, vim yog technical,

AC motors tsis tau sivkev lag luam, thiab txhua tus neeg siv DC motors.Hauv qhov chaw no, DC lub zog hluav taws xob tuaj yeem ua tau

hais tias yog ob txoj kev.Tsis tas li ntawd, cov khoom siv hluav taws xob ncaj qha muaj qhov zoo dua uas hloov tam sim no tsis tuaj yeem sib xws, thiab nws yooj yim rau kev khaws cia,

tsuav yog muaj roj teeb,nws tuaj yeem khaws cia.Yog tias lub tshuab hluav taws xob tsis ua haujlwm, nws tuaj yeem hloov mus rau lub roj teeb rau lub zog hluav taws xob

xwm txheej ceev.Peb nquag sivUPS system yeej yog DC roj teeb, tab sis nws hloov mus rau AC lub zog ntawm qhov kawg tso zis

los ntawm lub zog hluav taws xob technology.Txawm tias fais fab nroj tsuagthiab substations yuav tsum tau nruab nrog DC roj teeb los xyuas kom meej lub hwj chim

muab cov khoom siv tseem ceeb.

Yog li, qhov hloov pauv tam sim no zoo li cas rov qab los?Nws hais tau tias tsis muaj leej twg tuaj yeem sib ntaus.Mature AC generators - tsis muaj nyob;

transformers rau lub hwj chim kis tau tus mob - tsawg heev efficiency (tsis kam thiab to flux tshwm sim los ntawm linear hlau core qauv yog loj);

raws li cov neeg siv khoom,Yog tias DC motors txuas nrog AC lub zog, lawv tseem yuav luag, nws tsuas yog suav tias yog kev kho kom zoo nkauj xwb.

Qhov tseem ceeb tshaj plaws yog cov neeg siv kev paub - lub zog hluav taws xob ruaj khov yog qhov tsis zoo.Tsis tsuas yog hloov tam sim no tsis tuaj yeem khaws cia

zoo li directtam sim no, tab sis qhov hloov pauv tam sim no siv cov khoom thauj khoom ntawm lub sijhawm ntawd, thiab ntxiv lossis tshem tawm cov khoom thauj ntawm kab yuav

ua rau muaj kev hloov hauv covvoltage ntawm tag nrho cov kab.Tsis muaj leej twg xav kom lawv cov qij flicker thaum lub teeb ntawm lub qhov rooj qhib thiab tawm.

Yuav Ua Li Cas Hloov Tam Sim No

Technology tab tom txhim kho, thiab tsis ntev, xyoo 1884, cov neeg Hungarians tau tsim lub tshuab hluav taws xob kaw-core zoo.Cov tub ntxhais hlau ntawm

qhov no transformerua tiav cov hlau nplaum sib nqus, uas tuaj yeem txhim kho qhov ua tau zoo ntawm lub transformer thiab tsis txhob poob zog.

Nws yeej yog tib yamqauv raws li lub transformer peb siv niaj hnub no.Cov teeb meem kev ruaj ntseg kuj raug daws raws li cov khoom siv hauv series

hloov los ntawm cov khoom siv sib txuas.Nrog rau cov cib fim no, Tesla thaum kawg tuaj rau ntawm qhov chaw, thiab nws tau tsim lub tswv yim hloov pauv

uas yuav siv tau nrog no hom tshiab ntawm transformer.Qhov tseeb, tib lub sij hawm xws li Tesla, muaj ntau ntau ntawm invention patents ntsig txog

rau alternators, tab sis Tesla muaj ntau qhov zoo, thiab muaj nuj nqis los ntawmWestinghouse thiab nce qib ntawm qhov loj.

Raws li qhov kev thov rau hluav taws xob, yog tias tsis muaj kev thov, ces tsim kev thov.Yav dhau los AC fais fab system yog ib-theem AC,

thiab Teslatau tsim ib lub tswv yim ntau-theem AC asynchronous lub cev muaj zog, uas muab AC lub sijhawm los qhia nws cov txuj ci.

Muaj ntau cov txiaj ntsig ntawm ntau theem hloov tam sim no, xws li cov qauv yooj yim thiab tus nqi qis dua ntawm cov kab sib txuas thiab hluav taws xob.

khoom siv,thiab qhov tshwj xeeb tshaj yog nyob rau hauv lub cev muaj zog tsav.Multi-phase alternating tam sim no yog tsim los ntawm sinusoidal alternating tam sim no nrog

ib lub kaum sab xis ntawm theemtxawv.Raws li peb txhua tus paub, kev hloov pauv tam sim no tuaj yeem tsim kev hloov pauv magnetic teb.Hloov mus hloov.Yog tias

kev npaj yog tsim nyog, cov hlau nplaumteb yuav rotate ntawm ib tug tej zaus.Yog tias nws siv hauv lub cev muaj zog, nws tuaj yeem tsav lub rotor kom tig,

uas yog ntau theem AC lub cev muaj zog.Lub cev muaj zog tsim los ntawm Tesla raws li lub hauv paus ntsiab lus no tsis tas yuav muab cov hlau nplaum rau

lub rotor, uas zoo heev simplifies tus qauvthiab tus nqi ntawm lub cev muaj zog.Interestingly, Musk lub "Tesla" hluav taws xob tsheb kuj siv AC asynchronous

motors, tsis zoo li kuv lub teb chaws lub tsheb fais fab uas feem ntau sivsynchronous motors.

Thaum peb tuaj txog ntawm no, peb pom tias AC fais fab tau sib npaug nrog DC ntawm kev tsim hluav taws xob, kev xa tawm thiab kev siv,

yog li cas nws thiaj li nce mus rau saum ntuj thiab tuav tag nrho lub hwj chim lag luam?

Qhov tseem ceeb nyob hauv tus nqi.Qhov sib txawv ntawm qhov poob hauv cov txheej txheem sib kis ntawm ob tau ua tiav qhov sib txawv ntawm qhov sib txawv

DC thiab AC kis tau tus mob.

Yog tias koj tau kawm paub txog hluav taws xob yooj yim, koj yuav paub tias nyob rau hauv kev sib kis hluav taws xob ntev, qhov hluav taws xob qis yuav ua rau

poob ntau dua.Qhov kev poob no yog los ntawm cov cua sov uas tsim los ntawm cov kab tsis kam, uas yuav ua rau tus nqi ntawm cov nroj tsuag hluav taws xob tsis muaj dab tsi.

Cov zis hluav taws xob ntawm Edison's DC generator yog 110V.Xws li qhov tsis tshua muaj hluav taws xob xav tau lub chaw nres tsheb fais fab yuav tsum tau nruab ze rau txhua tus neeg siv.Hauv

cov cheeb tsam uas siv hluav taws xob loj thiab cov neeg siv ntom ntom, cov khoom siv hluav taws xob tsuas yog ob peb mais xwb.Piv txwv li, Edison

tsim thawj DC fais fab mov system nyob rau hauv Beijing nyob rau hauv 1882, uas tsuas yog muab lub hwj chim rau cov neeg siv nyob rau hauv 1.5km nyob ib ncig ntawm lub fais fab nroj tsuag.

Tsis hais txog cov nqi tsim kho vaj tse ntawm ntau lub tuam txhab hluav taws xob, lub zog hluav taws xob ntawm cov chaw tsim hluav taws xob kuj yog qhov teeb meem loj.Lub sijhawm ntawd,

txhawm rau txuag cov nqi, nws yog qhov zoo tshaj los tsim cov chaw tsim hluav taws xob nyob ze cov dej ntws, kom lawv tuaj yeem tsim hluav taws xob ncaj qha los ntawm dej.Txawm li cas los xij,

Txhawm rau muab hluav taws xob rau cov chaw nyob deb ntawm cov dej, thermal fais fab yuav tsum tau siv los tsim hluav taws xob, thiab tus nqi

kev hlawv cov thee kuj tau nce ntau heev.

Lwm qhov teeb meem kuj tshwm sim los ntawm kev xa hluav taws xob mus ntev.Cov kab ntev dua, qhov ntau dua qhov tsis kam, qhov voltage ntau dua

poob rau ntawm txoj kab, thiab qhov voltage ntawm tus neeg siv ntawm qhov kawg kawg yuav tsawg heev uas nws siv tsis tau.Txoj kev daws tsuas yog nce ntxiv

qhov tso zis hluav taws xob ntawm lub tshuab hluav taws xob, tab sis nws yuav ua rau qhov hluav taws xob ntawm cov neeg siv nyob ze siab dhau, thiab kuv yuav ua li cas yog tias cov khoom siv

puas hlawv tawm?

Tsis muaj teeb meem zoo li no nrog kev hloov tam sim no.Raws li ntev raws li ib tug transformer yog siv los boost lub voltage, fais fab kis ntawm kaum ntawm

kilometers tsis muaj teeb meem.Thawj AC fais fab mov system hauv North America tuaj yeem siv 4000V voltage los muab lub zog rau cov neeg siv 21km deb.

Tom qab ntawd, siv Westinghouse AC lub zog hluav taws xob, nws tseem ua tau rau Niagara Falls kom muaj zog Fabro, 30 mais deb.

Hmoov tsis zoo, tam sim no tsis tuaj yeem txhawb nqa hauv txoj kev no.Vim tias lub hauv paus ntsiab lus tau txais los ntawm AC boost yog electromagnetic induction,

yooj yim muab, qhov hloov tam sim no ntawm ib sab ntawm lub transformer tsim ib qho kev hloov magnetic teb, thiab hloov magnetic teb

tsim ib qho kev hloov pauv induced voltage (electromotive force) nyob rau sab nraud.Tus yuam sij rau lub transformer ua haujlwm yog qhov tam sim no yuav tsum

hloov, uas yog raws nraim li DC tsis muaj.

Tom qab ua tau raws li cov txheej txheem ntawm cov txheej txheem no, AC fais fab mov system ua tiav lub zog DC nrog nws tus nqi qis.

Edison lub tuam txhab hluav taws xob DC tau hloov kho sai sai rau lwm lub tuam txhab hluav taws xob nto moo - General Electric ntawm Tebchaws Meskas..
