Xyoo 1880, American inventor Edison tau tsim lub tshuab hluav taws xob DC loj hu ua "The Colossus", uas tau nthuav tawm ntawm Paris Exposition xyoo 1881.
Edison leej txiv ntawm direct tam sim no
Nyob rau tib lub sijhawm, kev txhim kho ntawm lub tshuab hluav taws xob kuj tseem nyob rau hauv kev kawm.Lub tshuab hluav taws xob thiab lub cev muaj zog yog ob txoj haujlwm sib txawv ntawm tib lub tshuab.Siv nws raws li cov khoom tso tawm tam sim no yog lub tshuab hluav taws xob, thiab siv nws ua cov khoom siv hluav taws xob yog lub cev muaj zog.
Txoj cai thim rov qab ntawm lub tshuab hluav taws xob no tau ua pov thawj los ntawm lub sijhawm xyoo 1873. Ntawm kev nthuav qhia kev lag luam hauv Vienna xyoo no, ib tus neeg ua haujlwm tau ua yuam kev thiab txuas cov xaim mus rau lub tshuab hluav taws xob Gram.Nws tau pom tias lub rotor ntawm lub tshuab hluav taws xob hloov pauv thiab tam sim ntawd mus rau qhov sib txawv.Cov kev taw qhia tig thiab dhau los ua lub cev muaj zog.Txij thaum ntawd los, tib neeg tau pom tias DC lub cev muaj zog tuaj yeem siv los ua ob lub tshuab hluav taws xob thiab qhov tshwm sim thim rov qab ntawm lub cev muaj zog.Qhov kev tshawb pom uas tsis tau xav txog no tau muaj kev cuam tshuam loj heev rau kev tsim thiab tsim lub cev muaj zog.
Nrog rau kev tsim hluav taws xob tsim hluav taws xob thiab cov cuab yeej siv hluav taws xob, kev tsim thiab tsim cov motors kuj tau ua ntau thiab zoo meej.Los ntawm xyoo 1890, DC motors muaj tag nrho cov qauv tseem ceeb ntawm DC motors niaj hnub.Txawm hais tias DC lub cev muaj zog tau siv dav thiab tau tsim cov txiaj ntsig kev lag luam ntau hauv daim ntawv thov, nws tus kheej tsis txaus txwv nws txoj kev loj hlob ntxiv.Ntawd yog, nws tsis tuaj yeem daws qhov kev xa hluav taws xob mus ntev, thiab tsis tuaj yeem daws qhov teeb meem ntawm kev hloov hluav taws xob, yog li AC motors tau tsim sai heev.
Thaum lub sij hawm no, ob-theem motors thiab peb-theem motors tawm ib tug tom qab lwm.Nyob rau hauv 1885, tus Italian physicist Galileo Ferraris tau npaj lub hauv paus ntsiab lus ntawm rotating magnetic teb thiab tsim ib tug ob-theem asynchronous lub cev muaj zog qauv.Xyoo 1886, Nikola Tesla, uas tau tsiv mus rau Tebchaws Meskas, nws tus kheej tau tsim ob-theem asynchronous lub cev muaj zog.Nyob rau hauv 1888, Lavxias teb sab hluav taws xob engineer Dolivo Dobrovolsky ua ib tug peb-theem AC ib tug squirrel tawb asynchronous lub cev muaj zog.Kev tshawb fawb thiab kev loj hlob ntawm AC motors, tshwj xeeb tshaj yog kev vam meej ntawm peb-theem AC motors, tau tsim tej yam kev mob rau lub sij hawm ntev lub hwj chim kis tau tus mob, thiab nyob rau tib lub sij hawm tau txhim kho hluav taws xob technology mus rau ib tug tshiab theem.
Tesla, leej txiv ntawm kev hloov tam sim no
Nyob ib ncig ntawm 1880, British Ferranti tau txhim kho lub alternator thiab npaj lub tswv yim ntawm AC high-voltage kis tau tus mob.Nyob rau hauv 1882, Gordon nyob rau hauv teb chaws Askiv tsim ib tug loj ob-theem alternator.Xyoo 1882, Fab Kis Fab Kis Gorand thiab tus neeg Askiv Askiv John Gibbs tau txais daim ntawv pov thawj ntawm "Tsev Teeb Pom Kev thiab Lub Hwj Chim Fais Fab", thiab tau ua tiav qhov kev hloov pauv thawj zaug nrog tus nqi siv tau.cov cuab yeej tseem ceeb tshaj plaws.Tom qab ntawd, Westinghouse tau txhim kho kev tsim kho ntawm Gibbs transformer, ua rau nws hloov pauv nrog kev ua haujlwm niaj hnub.Xyoo 1891, Blow tau tsim lub tshuab hluav taws xob siab roj-immersed hauv Switzerland, thiab tom qab ntawd tsim lub tshuab hluav taws xob loj heev.Ntev-ntev high-voltage AC fais fab kis tau tus mob tau zoo heev vim muaj kev txhim kho tas mus li ntawm transformers.
Tom qab ntau tshaj 100 xyoo ntawm txoj kev loj hlob, txoj kev xav ntawm lub cev muaj zog nws tus kheej tau loj hlob tuaj.Txawm li cas los xij, nrog rau kev tsim hluav taws xob engineering, computer science thiab kev tswj hwm thev naus laus zis, kev txhim kho lub cev muaj zog tau nkag mus rau theem tshiab.Ntawm lawv, txoj kev loj hlob ntawm AC ceev tswj lub cev muaj zog yog qhov muag pom zoo tshaj plaws, tab sis nws tsis tau nrov thiab siv sij hawm ntev vim nws tau paub los ntawm cov khoom siv hluav taws xob thiab cov tshuab hloov pauv, thiab kev tswj xyuas tsis zoo li. uas yog DC ceev tswj.
Tom qab xyoo 1970, tom qab lub tshuab hluav taws xob hloov hluav taws xob tau qhia, cov teeb meem ntawm kev txo cov khoom siv, txo qhov loj me, txo tus nqi, txhim kho kev ua haujlwm, thiab tshem tawm cov suab nrov tau maj mam daws, thiab AC ceev kev tswj tau ua tiav mus rau pem hauv ntej.Tom qab tsim cov vector tswj, qhov zoo li qub thiab dynamic kev ua tau zoo ntawm AC ceev tswj qhov system tau txhim kho.Tom qab tau txais kev tswj hwm microcomputer, vector tswj algorithm tau paub los ntawm software los ua qauv ntawm cov khoom siv hluav taws xob, yog li txo tus nqi thiab txhim kho kev ntseeg siab, thiab nws tseem tuaj yeem ua kom paub ntau ntxiv txog kev tswj cov tshuab.Kev nce qib sai ntawm cov hluav taws xob hluav taws xob thiab microcomputer tswj thev naus laus zis yog lub zog tsav rau kev hloov kho txuas ntxiv ntawm AC ceev tswj qhov system.
Nyob rau hauv xyoo tas los no, nrog txoj kev loj hlob sai ntawm cov khoom siv hlau nplaum tsis tshua muaj hauv ntiaj teb thiab kev txhim kho ntawm cov tshuab hluav taws xob hluav taws xob, cov hlau nplaum ruaj khov tau ua tiav zoo.Cov motors thiab generators siv NdFeB cov khoom siv hlau nplaum ruaj khov tau siv dav, xws li los ntawm lub nkoj propulsion mus rau lub plawv dhia ntshav.Superconducting motors twb tau siv rau kev tsim hluav taws xob thiab kev txhawb nqa ntawm high-speed maglev tsheb ciav hlau thiab nkoj.
Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, kev txhim kho kev ua tau zoo ntawm cov khoom siv raw thiab kev txhim kho cov txheej txheem tsim khoom, cov motors tau raug tsim tawm nrog ntau txhiab tus ntau yam thiab cov lus qhia tshwj xeeb, lub zog ntawm ntau qhov sib txawv (los ntawm ob peb lab ntawm ib. watt mus rau ntau tshaj 1000MW), thiab dav heev.Ntau yam (los ntawm ob peb hnub mus rau ntau pua txhiab tus kiv puag ncig ib feeb), hloov pauv ib puag ncig ib puag ncig (xws li av tiaj tus, toj siab, huab cua, hauv qab dej, roj, thaj chaw txias, thaj chaw sov, ntub dej kub, qhuav tropics, sab hauv tsev, sab nraum zoov, Tsheb , nkoj, ntau yam xov xwm, thiab lwm yam), kom tau raws li cov kev xav tau ntawm ntau yam kev lag luam ntawm lub teb chaws kev lag luam thiab tib neeg lub neej.
