Raws li peb txhua tus paub, cov tshuab hluav taws xob tuaj yeem muab faib ua DC generators thiab AC generators.Tam sim no, alternator yog dav siv, thiab yog li hydro generator.Tab sis nyob rau hauv thaum ntxov xyoo, DC generators nyob tag nrho cov lag luam, yog li cas AC generators tuav lub lag luam?Dab tsi yog qhov kev sib txuas ntawm hydro generators ntawm no?Qhov no yog hais txog kev sib ntaus sib tua ntawm AC thiab DC thiab 5000hp hydro generator ntawm Adams fais fab chaw nres tsheb hauv Niagara Falls.
Ua ntej qhia Niagara Falls hydro generator, peb yuav tsum pib nrog AC / DC tsov rog tseem ceeb hauv keeb kwm ntawm kev tsim hluav taws xob.
Edison yog ib tus neeg tsim khoom nto moo Asmeskas.Nws yug los hauv kev txom nyem thiab tsis muaj kev kawm ntawv hauv tsev kawm ntawv.Txawm li cas los xij, nws tau txais ze li ntawm 1300 qhov kev tsim khoom patents hauv nws lub neej los ntawm kev tso siab rau nws qhov kev txawj ntse txawv tshaj plaw thiab tus kheej tawm tsam.Thaum Lub Kaum Hli 21, 1879, nws tau thov rau qhov kev tsim patent ntawm carbon filament incandescent teeb (No. 22898);Xyoo 1882, nws tau tsim Edison lub tuam txhab hluav taws xob teeb los tsim cov teeb taws teeb thiab lawv lub tshuab hluav taws xob DC.Nyob rau hauv tib lub xyoo, nws tsim lub ntiaj teb thawj loj-scale thermal fais fab nroj tsuag nyob rau hauv New York.Nws muag ntau tshaj 200000 qhov muag teev nyob rau hauv peb lub xyoos thiab monopolized tag nrho lub khw.Edison's DC generators kuj muag tau zoo nyob rau hauv Teb Chaws Asmeskas.
Xyoo 1885, thaum Edison nyob rau ntawm nws lub ncov, American steinhouse tau pom zoo txog qhov yug tshiab AC fais fab mov.Xyoo 1885, Westinghouse tau yuav daim ntawv pov thawj ntawm AC teeb pom kev zoo thiab cov khoom siv hluav taws xob siv los ntawm gaulard thiab Gibbs hauv Tebchaws Meskas thaum Lub Ob Hlis 6, 1884 (US Patent No. 0.297924).Xyoo 1886, Westinghouse thiab Stanley (W. Stanley, 1856-1927) tau ua tiav hauv kev txhawb nqa ib-theem AC mus rau 3000V nrog lub transformer hauv Great Barrington, Massachusetts, Tebchaws USA, xa mus rau 4000ft, thiab tom qab ntawd txo qhov voltage mus rau 500V.Tsis ntev, Westinghouse tau tsim thiab muag ntau lub teeb pom kev zoo AC.Xyoo 1888, Westinghouse tau yuav daim ntawv pov thawj ntawm Tesla, "tus kws tshaj lij hluav taws xob", ntawm AC lub cev muaj zog, thiab ntiav Tesla los ua haujlwm hauv Westinghouse.Nws tau cog lus tias yuav tsim AC lub cev muaj zog thiab txhawb nqa daim ntawv thov ntawm AC lub cev muaj zog, thiab ua tiav kev ua tiav.Kev vam meej ntawm Westinghouse nyob rau hauv kev txhim kho alternating tam sim no attracted lub khib ntawm invincible Edison thiab lwm tus neeg.Edison, HP xim av thiab lwm cov ntawv luam tawm hauv cov ntawv xov xwm thiab cov ntawv xov xwm, coj kom zoo dua ntawm pej xeem kev ntshai ntawm hluav taws xob nyob rau lub sijhawm ntawd, tsuas yog tshaj tawm txog kev phom sij ntawm kev hloov tam sim no, thov tias "txhua lub neej nyob ze ntawm tus neeg hloov pauv tam sim no tsis tuaj yeem muaj sia nyob" Tsis muaj nyob. tsim muaj peev xwm ciaj sia nyob rau hauv qhov txaus ntshai ntawm conductors nqa lwm txoj kev tam sim no Nyob rau hauv nws tsab xov xwm, nws tawm tsam kev siv AC nyob rau hauv ib qho kev sim strangle AC nyob rau hauv nws cov me nyuam mos.Tawm tsam Edison thiab lwm tus, Westinghouse thiab lwm tus kuj tau sau cov ntawv los tiv thaiv AC.Raws li qhov tshwm sim ntawm kev sib cav, AC sab maj mam yeej.DC sab tsis kam plam, HP Brown (thaum nws yog Edison lub chaw kuaj sim) Nws kuj tau txhawb thiab txhawb nqa lub xeev lub rooj sib txoos kom dhau ib tsab cai lij choj rau kev tua lub txim tuag los ntawm hluav taws xob, thiab thaum lub Tsib Hlis 1889, nws tau yuav peb lub tshuab hluav taws xob tsim tawm. los ntawm Westinghouse thiab muag lawv mus rau hauv tsev lojcuj raws li lub hwj chim mov rau lub rooj zaum electrocution.Nyob rau hauv lub qhov muag ntawm ntau tus neeg, alternating tam sim no yog lub ntsiab lus ntawm tus Vajtswv ntawm kev tuag.Nyob rau tib lub sijhawm, Pawg Neeg Sawv Cev ntawm Edison sab tau tsim cov kev xav rau pej xeem: "Lub rooj zaum hluav taws xob yog qhov pov thawj tias kev hloov tam sim no ua rau tib neeg yooj yim tuag.Hauv kev teb, Westinghouse tau tuav lub rooj sib tham rau tat xov xwm.Tesla tus kheej khi cov xov hlau thoob plaws nws lub cev thiab txuas lawv mus rau ib txoj hlua ntawm qhov muag teev.Thaum qhov hloov pauv tam sim no tau qhib, lub teeb hluav taws xob tau ci, tab sis Tesla muaj kev nyab xeeb.Raws li qhov xwm txheej tsis zoo ntawm pej xeem kev xav tsis ua tiav, DC sab sim tua cov hloov pauv tam sim no raug cai.
Nyob rau lub caij nplooj ntoo hlav ntawm 890, qee tus neeg sawv cev hauv Virginia tau thov ib daim ntawv thov "rau kev tiv thaiv kev phom sij los ntawm hluav taws xob" Thaum pib lub Plaub Hlis, cov thawj coj tau tsim tsa pawg txiav txim los tuav lub rooj sib hais.Edison thiab Morton, tus thawj coj ntawm lub tuam txhab, thiab LB Stillwell, engineer ntawm Westinghouse (1863-1941) Thiab kws lij choj kws lij choj h.Levis tuaj koom lub rooj sib hais.Kev tuaj txog ntawm lub npe nrov Edison thaiv lub rooj sib tham.Edison tau hais sensationally ntawm lub rooj sib hais: "txoj tam sim no zoo li" tus dej ntws mus rau hauv hiav txwv ", thiab alternating tam sim no zoo li" roob torrents scouring cliffs ua nruj ua tsiv ” (lub torrent rushing ua nruj ua tsiv dhau ib tug precipice) "Morton kuj sim nws zoo tshaj plaws. tua AC, tab sis lawv cov lus tim khawv tsis muaj ntsiab lus thiab tsis ntseeg, uas ua rau cov neeg tuaj saib thiab cov neeg txiav txim poob rau hauv huab cua.Cov neeg tim khawv los ntawm Westinghouse thiab ntau lub tuam txhab hluav taws xob hluav taws xob tsis lees paub qhov kev sib cav tias AC yog qhov txaus ntshai heev nrog cov lus qhia meej thiab meej thiab kev coj ua ntawm 3000V hluav taws xob teeb uas lawv tau siv dav.Thaum kawg, pawg txiav txim plaub tau txiav txim siab tom qab kev sib cav tom qab Virginia, Ohio thiab lwm lub xeev tsis ntev los no tsis kam lees cov lus tsa suab zoo sib xws.Txij thaum ntawd los, AC tau maj mam txais los ntawm cov neeg, thiab Westinghouse muaj lub koob npe nrov hauv kev ua tsov ua rog ntawm kev sib txuas lus (piv txwv li, xyoo 1893, nws tau txais daim ntawv cog lus rau 250000 qhov muag teev ntawm Chicago Fair) Edison Electric Light Company, uas yog swb nyob rau hauv AC / DC tsov rog, yog discredited thiab unsustainable.Nws yuav tsum tau koom ua ke nrog Thomson Houston lub tuam txhab hauv 1892 los tsim lub tuam txhab hluav taws xob dav dav (GE) Thaum lub tuam txhab tau tsim, nws tau tso tseg Edison lub tswv yim ntawm kev tawm tsam kev tsim cov khoom siv AC, tau txais kev ua haujlwm ntawm kev tsim khoom AC ntawm thawj Thomson Houston. tuam txhab, thiab nquag txhawb kev txhim kho cov khoom siv AC.
Cov saum toj no yog ib qho kev sib ntaus sib tua tseem ceeb ntawm AC thiab DC hauv keeb kwm ntawm kev tsim lub cev muaj zog.Qhov kev tsis sib haum xeeb thaum kawg tau xaus tias qhov kev puas tsuaj ntawm AC tsis txaus ntshai li cov neeg txhawb nqa DC tau hais.Tom qab qhov kev daws teeb meem no, lub tshuab hloov pauv tau pib coj mus rau lub caij nplooj ntoo hlav ntawm txoj kev loj hlob, thiab nws cov yam ntxwv thiab qhov zoo tau pib nkag siab thiab maj mam txais los ntawm tib neeg.Qhov no kuj yog tom qab hauv Niagara Falls Ntawm cov tshuab hluav taws xob hauv qhov chaw nres tsheb hydropower, lub tshuab hloov pauv yog qhov tseem ceeb los yeej dua.
