Hauv kab lus kawg, peb tau qhia txog kev daws teeb meem ntawm DC AC."kev ua tsov ua rog" xaus nrog kev yeej ntawm AC.Yog li ntawd, AC tau txais lub caij nplooj ntoos hlav ntawm kev lag luam kev loj hlob thiab pib ua lag luam nyob rau yav dhau los DC.Tom qab qhov "kev ua tsov ua rog", DC thiab AC tau sib tw hauv Adams chaw nres tsheb hydropower ntawm Niagara Falls.
Xyoo 1890, Tebchaws Meskas tau tsim lub chaw nres tsheb Niagara Falls Adams hydropower.Txhawm rau ntsuas ntau yam AC thiab DC schemes, lub teb chaws thiab thoob ntiaj teb Niagara Power Commission tau tsim.Westinghouse thiab Ge tau koom nrog hauv kev sib tw.Thaum kawg, nrog nws lub koob npe nrov tom qab kev yeej ntawm AC / DC kev ua tsov ua rog thiab cov txuj ci ntawm ib pab pawg kws tshawb fawb zoo xws li Tesla, nrog rau kev sim ua tiav ntawm AC kis tau tus mob hauv Great Barrington hauv 1886 thiab kev ua tiav ntawm alternator hauv larffen. Fais fab nroj tsuag nyob rau hauv lub teb chaws Yelemees, Westinghouse thaum kawg yeej qhov kev cog lus ntawm 10 5000P AC hydro generators.Xyoo 1894, thawj 5000P hydro generator ntawm Niagara Falls Adams fais fab chaw nres tsheb tau yug hauv Westinghouse.Xyoo 1895, thawj chav tsev tau muab tso rau hauv kev ua haujlwm.Thaum lub caij nplooj zeeg xyoo 1896, ob-theem hloov tam sim no los ntawm lub tshuab hluav taws xob tau hloov mus rau peb-theem los ntawm Scot transformer, thiab tom qab ntawd xa mus rau Baffalo 40km deb ntawm peb-theem kis tau tus mob.
Lub tshuab hluav taws xob ntawm Adams fais fab chaw nres tsheb ntawm Niagara Falls tau tsim los ntawm BG lamme (1884-1924), tus thawj coj ntawm Westinghouse, raws li Tesla's patent, thiab nws tus muam B. lamme kuj tau koom nrog tsim.Chav tsev yog tsav los ntawm fournellon turbine (ob chav khiav, tsis muaj cua ntsawj ntshab raj), thiab lub tshuab hluav taws xob yog ntsug ob-theem synchronous generator, 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, ib chav tsev muaj peev xwm ntawm hydro generator tsis tshaj 1000 HPA.Nws tuaj yeem hais tias 5000bp hydro generator ntawm Adar hydropower chaw nres tsheb hauv Niagara Falls tsis yog tsuas yog lub tshuab hluav taws xob loj tshaj plaws nrog ib chav tsev muaj peev xwm nyob hauv lub ntiaj teb thaum lub sijhawm ntawd, tab sis kuj yog thawj kauj ruam tseem ceeb hauv kev txhim kho hydro generator los ntawm me mus rau loj. .
(2) Lub armature conductor yog insulated nrog mica thawj zaug.
(3) Qee cov qauv qauv ntawm cov tshuab hluav taws xob niaj hnub no tau txais yuav, xws li lub kaus ntsug kaw.Thawj 8 pawg yog ntawm cov qauv uas cov ncej hlau nplaum nyob ruaj khov sab nraud (pivot hom), thiab ob qhov kawg tau hloov mus rau cov qauv tam sim no uas cov hlau nplaum tig sab hauv ( hom teb ).
(4) Hom excitation tshwj xeeb.Thawj tus siv DC lub zog tsim los ntawm lub zeem muag DC chav turbine generator rau excitation.Tom qab ob los yog peb xyoos, tag nrho cov chav yuav siv me me DC hydro generators ua exciters.
(5) Qhov zaus ntawm 25Hz tau txais yuav.Lub sijhawm ntawd, Ying tus nqi ntawm Tebchaws Meskas yog ntau yam, los ntawm 16.67hz txog 1000fhz.Tom qab kev tsom xam thiab kev sib haum xeeb, 25Hz tau txais yuav.Qhov zaus no tau dhau los ua tus qauv zaus hauv qee qhov chaw hauv Tebchaws Meskas tau ntev.
(6) Yav dhau los, hluav taws xob tsim los ntawm cov cuab yeej tsim hluav taws xob feem ntau yog siv rau kev teeb pom kev zoo, thaum hluav taws xob tsim los ntawm Niagara Falls Adams fais fab chaw nres tsheb feem ntau yog siv rau kev lag luam fais fab.
(7) Kev xa mus rau kev lag luam mus ntev ntawm peb-theem AC tau ua tiav thawj zaug, uas tau ua lub luag haujlwm ua qauv hauv kev sib kis thiab kev siv dav ntawm peb-theem AC.Tom qab 10 xyoo ntawm kev ua haujlwm, 10 5000bp dej turbine generator units ntawm Adams hydropower chaw nres tsheb tau raug kho thiab hloov pauv.Tag nrho 10 units tau raug hloov nrog cov tshiab units ntawm 1000HP thiab 1200V, thiab lwm 5000P tshiab unit tau raug ntsia, kom tag nrho cov ntsia muaj peev xwm ntawm lub hwj chim chaw nres tsheb mus txog 105000hp.
Kev sib ntaus sib tua ntawm AC ncaj qha ntawm lub tshuab hluav taws xob yog thaum kawg yeej los ntawm AC.Txij thaum ntawd los, qhov tseem ceeb 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 nrov rau kev tsim cov tshuab hluav taws xob hauv lub neej yav tom ntej.Txawm li cas los xij, nws tsim nyog hais tias qhov tseem ceeb ntawm thawj theem 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.Ob lub tshuab hluav taws xob txuas nrog hauv series thiab tsav los ntawm ib lub turbine.Qhov thib ob yog lub tshuab hluav taws xob high-voltage, uas yog ob chav pivot thiab ob chav ncej generator sib koom ib ncej.Cov ntsiab lus yuav qhia nyob rau hauv tsab xov xwm tom ntej.
