Maqaalkii u dambeeyay, waxaan soo bandhignay xallinta DC AC. "dagaalku" wuxuu ku dhamaaday guushii AC. sidaas darteed, AC waxay heshay guga horumarka suuqa waxayna bilowday inay qabsato suuqii ay hore DC u qabsan jirtay. Ka dib "dagaalkan", DC iyo AC waxay ku tartamayeen saldhiga tamarta ee Adams ee Niagara Falls.
Sannadkii 1890-kii, Maraykanku wuxuu dhisay saldhigga tamarta Niagara Falls Adams. Si loo qiimeeyo nidaamyada AC iyo DC ee kala duwan, waxaa la aasaasay komishanka tamarta Niagara heer qaran iyo caalami ah. Westinghouse iyo Ge ayaa ka qayb qaatay tartanka. Ugu dambeyntii, iyada oo sumcaddeeda sii kordheysa ka dib guushii AC / DC ee dagaalka iyo kartida koox saynisyahano ah oo aad u fiican sida Tesla, iyo sidoo kale tijaabinta guuleysiga ee gudbinta AC ee Great Barrington 1886 iyo hawlgalkii guusha ee alternator ee warshad koronto larffen ee Jarmalka, Westinghouse ayaa ugu dambeyntii ku guuleysatay qandaraaska wax soo saarka ee 10 5000P AC hydrogenerator. Sannadkii 1894-kii, koronto-dhaliyaha biyaha ee 5000P ee Niagara Falls Adams wuxuu ku dhashay Westinghouse. Sannadkii 1895-kii, cutubkii ugu horreeyay ayaa la hawlgeliyay. Xilligii dayrta ee 1896-kii, hadda beddelka laba weji ee uu soo saaray koronto-dhaliye ayaa loo beddelay saddex weji iyada oo loo sii marayo Scot Transformer, ka dibna waxaa loo gudbiyay Baffalo oo 40km u jirta iyada oo loo marayo nidaamka gudbinta saddex weji.
Koronto dhaliyaha tamarta Adams ee ku taal Niagara Falls waxaa naqshadeeyay BG lamme (1884-1924), injineerka ugu sareeya Westinghouse, sida uu qabo shatiga Tesla, iyo walaashii B. lamme ayaa sidoo kale ka qayb qaadatay naqshadeynta. Unugga waxaa wada marawaxadaha fournellon ah (laba orodyahan ah, oo aan lahayn tuubo qabyo ah), koronto-dhaliye waa koronto-dhaliye laba-waji ah oo toosan, 5000hp, 2000V, 25Hz, 250r / mln. Koronto-dhaliyuhu wuxuu leeyahay sifooyinka soo socda;
(1) Awood weyn iyo cabbir dheer. Intaa ka hor, halbeegga halbeegga koronto dhaliyaha kama badnaan 1000 HPA. Waxa la odhan karaa koronto-dhaliyaha biyaha ee 5000bp ee xarunta tamarta Adar ee Niagara Falls ma ahayn oo kaliya koronto-dhaliyaha ugu weyn ee awooda halbeeg ee adduunka wakhtigaas, laakiin sidoo kale talaabada ugu horeysa ee muhiimka ah ee horumarinta koronto-dhaliyaha biyaha yar ilaa weyn.
(2) Kidhiyaha hubku waxa lagu dahaadhay mica markii ugu horeysay.
(3) Qaar ka mid ah qaababka aasaasiga ah ee soo-saareyaasha biyaha ee maanta ayaa la qaatay, sida qaab dhismeed xiran oo dallad toosan ah. 8-da qaybood ee ugu horreeya waxay ka mid yihiin qaab-dhismeedka ay tiirarka birlabku ku taagan yihiin dibadda (nooca pivot), labada qaybood ee ugu dambeeyana waxa loo beddelaa qaab-dhismeedka guud ee hadda jira oo ay tiirarka birlabku ku wareegaan gudaha (nooca goobta).
(4) Habka kicinta gaarka ah. Midka kowaad wuxuu u isticmaala tamarta DC ee uu dhaliyo mashiinnada uumiga DC ee u dhow si ay u kiciso. Laba ama saddex sano ka dib, dhammaan cutubyada waxay isticmaali doonaan koronto-dhaliyeyaal yar oo DC ah.
(5) Inta jeer ee 25Hz ayaa la qaatay. Waqtigaas, heerka Ying ee Maraykanku wuxuu ahaa mid aad u kala duwan, min 16.67hz ilaa 1000fhz. Falanqaynta iyo tanaasulka ka dib, 25Hz ayaa la qaatay. Soo noqnoqoshadani waxay noqotay inta jeer ee caadiga ah ee qaybo ka mid ah Maraykanka muddo dheer.
(6) Waagii hore, korontada ay dhaliso qalabka korontadu inta badan waxaa loo isticmaali jiray nalalka, halka korontada ay dhaliso saldhigga korontada ee Niagara Falls Adams inta badan loo isticmaali jiray tamarta warshadaha.
(7) Gudbinta ganacsiga fogaanta fog ee saddexda weji AC ayaa la rumeeyay markii ugu horreysay, taas oo door ku dayasho leh ka qaadatay gudbinta iyo adeegsiga ballaaran ee saddexda weji ee AC. 10 sano oo shaqo ka dib, 10 5000bp unug dhaliye marawaxadaha biyaha ee saldhiga tamarta Adams ayaa si buuxda loo cusboonaysiiyay oo la bedelay. Dhammaan 10-ka unug waxa lagu beddelay unugyo cusub oo kala ah 1000HP iyo 1200V, waxaana la rakibay unug kale oo 5000P ah, si guud ahaan awoodda xarunta korontada lagu rakibay u gaadho 105000hp.
Dagaalkii tooska ahaa ee AC ee koronto-dhaliyaha biyaha waxaa ugu dambeyntii ku guuleystay AC. Intaa wixii ka danbeeyay waxa dhaawac wayn soo gaadhay firfircoonidii DC-ga, AC waxa ay bilowday in ay heeso oo ay suuqa ka weerarto, taas oo sidoo kale dejisay qaabka mustaqbalka loo horumarin karo mishiinnada biyaha dhaliya. Si kastaba ha ahaatee, waxaa mudan in la xuso in sifada cajiibka ah ee marxaladda hore ay tahay in koronto-dhaliyeyaasha DC-ga si weyn loo isticmaalo. Waqtigaas, waxaa jiray laba nooc oo ah matoorrada biyaha ee DC. Mid waa koronto-dhaliyaha hooseeya. Laba koronto-dhaliye ayaa si isdaba-joog ah isugu xiran waxaana wada hal marawaxadaha. Midda labaad waa koronto-dhaliyaha sare-sare, kaas oo ah koronto-dhaliye laba-jibbaaran iyo laba-jibbaarane oo wadaagaya hal usheeda dhexe. Faahfaahinta waxaa lagu soo bandhigi doonaa maqaalka soo socda.
