Hauv tsab xov xwm kawg, peb tau qhia txog kev daws teeb meem ntawm DC AC. "kev ua tsov rog" xaus nrog kev yeej ntawm AC. yog li ntawd, AC tau txais lub caij nplooj ntoo hlav ntawm kev txhim kho kev lag luam thiab pib nyob hauv kev lag luam uas DC tau nyob ua ntej. Tom qab "kev ua tsov rog" no, DC thiab AC tau sib tw hauv chaw nres tsheb hydropower Adams ntawm Niagara Falls.
Xyoo 1890, Tebchaws Meskas tau tsim lub chaw nres tsheb hydropower Niagara Falls Adams. Yuav kom ntsuam xyuas ntau yam AC thiab DC schemes, lub koom haum Niagara Power Commission hauv tebchaws thiab thoob ntiaj teb tau tsim tsa. Westinghouse thiab Ge tau koom nrog kev sib tw. Thaum kawg, nrog nws lub koob npe nrov tom qab yeej ntawm AC / DC tsov rog thiab cov txuj ci ntawm ib pawg kws tshawb fawb zoo heev xws li Tesla, nrog rau kev sim ua tiav ntawm AC kis tau tus mob hauv Great Barrington xyoo 1886 thiab kev ua haujlwm zoo ntawm alternator hauv larffen fais fab nroj tsuag hauv lub tebchaws Yelemees, Westinghouse thaum kawg yeej daim ntawv cog lus tsim khoom ntawm 10 5000P AC hydro generators. Xyoo 1894, thawj 5000P hydro generator ntawm Niagara Falls Adams fais fab chaw nres tsheb tau yug los hauv Westinghouse. Xyoo 1895, thawj chav tsev tau muab tso rau hauv kev ua haujlwm. Thaum lub caij nplooj zeeg xyoo 1896, ob-theem alternating tam sim no tsim los ntawm lub generator tau hloov mus rau hauv peb-theem los ntawm Scot transformer, thiab tom qab ntawd xa mus rau Baffalo 40km deb los ntawm peb-theem kis tau tus mob.
Lub tshuab hluav taws xob hydrogen ntawm Adams fais fab chaw nres tsheb ntawm Niagara Falls tau tsim los ntawm BG lamme (1884-1924), tus thawj coj engineer ntawm Westinghouse, raws li Tesla daim ntawv pov thawj, thiab nws tus muam B. lamme kuj tau koom nrog hauv kev tsim. Lub tshuab yog tsav los ntawm plaub nellon turbine (ob chav khiav, tsis muaj lub raj xa dej), thiab lub tshuab hluav taws xob yog lub tshuab hluav taws xob ntsug ob-theem synchronous, 5000hp, 2000V, 25Hz, 250r / mln. Lub tshuab hluav taws xob muaj cov yam ntxwv hauv qab no;
(1) Muaj peev xwm loj thiab ntev. Ua ntej ntawd, lub peev xwm ntawm lub tshuab hluav taws xob hydro generator tsis pub tshaj 1000 HPA. Nws tuaj yeem hais tias lub tshuab hluav taws xob hydro 5000bp ntawm Adar hydropower chaw nres tsheb hauv Niagara Falls tsis yog tsuas yog lub tshuab hluav taws xob hydro loj tshaj plaws nrog lub peev xwm ib chav hauv ntiaj teb thaum lub sijhawm ntawd, tab sis kuj yog thawj kauj ruam tseem ceeb hauv kev txhim kho lub tshuab hluav taws xob hydro los ntawm me mus rau loj.
(2) Tus neeg tsav tsheb armature yog insulated nrog mica thawj zaug.
(3) Qee cov qauv tseem ceeb ntawm cov tshuab hluav taws xob hydro niaj hnub no tau txais yuav, xws li cov qauv kaw ntsug. 8 pawg thawj zaug yog cov qauv uas cov ncej sib nqus nyob ruaj khov sab nraud (hom pivot), thiab ob pawg kawg tau hloov mus rau cov qauv dav dav tam sim no uas cov ncej sib nqus tig sab hauv (hom teb).
(4) Hom kev txhawb zog tshwj xeeb. Thawj qhov siv lub zog DC uas tsim los ntawm lub tshuab hluav taws xob DC turbine ze rau kev txhawb zog. Tom qab ob lossis peb xyoos, txhua chav yuav siv cov tshuab hluav taws xob DC me me ua cov khoom txhawb zog.
(5) Lub zaus ntawm 25Hz tau raug saws txais. Lub sijhawm ntawd, tus nqi Ying ntawm Tebchaws Meskas yog ntau yam, los ntawm 16.67hz txog 1000fhz. Tom qab kev tshuaj xyuas thiab kev sib haum xeeb, 25Hz tau raug saws txais. Lub zaus no tau dhau los ua tus qauv zaus hauv qee qhov chaw ntawm Tebchaws Meskas tau ntev.
(6) Yav dhau los, hluav taws xob tsim los ntawm cov khoom siv hluav taws xob feem ntau yog siv rau teeb pom kev zoo, thaum hluav taws xob tsim los ntawm Niagara Falls Adams chaw nres tsheb fais fab feem ntau yog siv rau lub zog kev lag luam.
(7) Kev xa hluav taws xob mus rau kev lag luam deb ntawm peb-theem AC tau ua tiav thawj zaug, uas tau ua lub luag haujlwm zoo hauv kev xa hluav taws xob thiab kev siv dav ntawm peb-theem AC. Tom qab 10 xyoo ntawm kev ua haujlwm, 10 lub tshuab hluav taws xob dej turbine 5000bp ntawm Adams hydropower chaw nres tsheb tau hloov kho tshiab thiab hloov pauv tag nrho. Tag nrho 10 chav tau hloov pauv nrog cov chav tshiab ntawm 1000HP thiab 1200V, thiab lwm chav tshiab 5000P tau teeb tsa, yog li tag nrho cov peev xwm teeb tsa ntawm lub chaw fais fab ncav cuag 105000hp.
Qhov kev sib ntaus sib tua ntawm AC ncaj qha ntawm lub tshuab hluav taws xob hydro tau thaum kawg yeej los ntawm AC. Txij thaum ntawd los, lub zog ntawm DC tau raug puas tsuaj loj heev, thiab AC tau pib hu nkauj thiab tawm tsam hauv kev ua lag luam, uas kuj tau teeb tsa lub suab rau kev txhim kho cov tshuab hluav taws xob hydro yav tom ntej. Txawm li cas los xij, nws tsim nyog hais tias qhov tshwj xeeb ntawm theem pib yog tias DC hydro generators tau siv dav. Lub sijhawm ntawd, muaj ob hom DC hydro motors. Ib qho yog lub tshuab hluav taws xob qis-voltage. Ob lub tshuab hluav taws xob tau txuas nrog hauv series thiab tsav los ntawm ib lub turbine. Qhov thib ob yog lub tshuab hluav taws xob siab-voltage, uas yog ob lub pivot thiab ob lub ncej generator sib koom ib lub ncej. Cov ntsiab lus yuav raug qhia hauv tsab xov xwm tom ntej.
