Muchinyorwa chapfuura, takapa mhinduro yeDC AC. "Hondo" yakapera nekukunda kweAC. Saka, AC yakawana tsime rekukura kwemusika ndokutanga kutora musika waimbove wakatorwa neDC. Mushure me "hondo" iyi, DC neAC dzakakwikwidzana muchiteshi chemagetsi cheAdams paNiagara Falls.
Muna 1890, United States yakavaka chiteshi chemagetsi cheNiagara Falls Adams. Kuti vaongorore zvirongwa zvakasiyana-siyana zveAC neDC, Niagara Power Commission yenyika nepasi rose yakatangwa. Westinghouse neGe vakatora chikamu mumakwikwi aya. Pakupedzisira, nemukurumbira wayo uri kukura mushure mekukunda kwehondo yeAC / DC uye matarenda eboka revasayendisiti vakanaka vakaita saTesla, pamwe nekubudirira kwekuyedza AC transmission muGreat Barrington muna 1886 uye kubudirira kwekushanda kwealternator muchivako chemagetsi cheLarffen muGermany, Westinghouse yakazopedzisira yahwina kondirakiti yekugadzira majenareta gumi e5000P AC hydro. Muna 1894, jenareta yekutanga ye5000P hydro yechiteshi chemagetsi cheNiagara Falls Adams yakazvarwa muWestinghouse. Muna 1895, unit yekutanga yakaiswa kushanda. Mumatsutso a1896, magetsi maviri anoshandiswa nejenareta akachinjwa kuita matatu-phase kuburikidza neScot transformer, uye akazoendeswa kuBaffalo makiromita makumi mana kubva ipapo kuburikidza nesystem yekutumira matatu-phase.
Jenareta yemvura yechiteshi chemagetsi cheAdams kuNiagara Falls yakagadzirwa naBG lamme (1884-1924), mukuru wemainjiniya weWestinghouse, zvichienderana nepatent yaTesla, uye hanzvadzi yake B. lamme vakatorawo chikamu mukugadzira. Chigadzirwa ichi chinofambiswa nefournellon turbine (double runner, isina draft tube), uye jenareta iyi ijenareta yemagetsi ine zvikamu zviviri, 5000hp, 2000V, 25Hz, 250r / mln. Jenareta iyi ine hunhu hunotevera;
(1) Kukura kukuru uye kureba. Izvi zvisati zvaitika, simba remuchina wekugadzira hydro generator raidarika 1000 HPA. Zvinogona kutaurwa kuti muchina wekugadzira hydro generator weAdar hydropower station muNiagara Falls wakanga usiri chete muchina wekugadzira hydro generator mukuru une simba remuchina mumwe chete pasi rose panguva iyoyo, asiwo danho rekutanga guru mukugadzirwa kwemuchina wekugadzira hydro generator kubva padiki kusvika pakuru.
(2) Muchina wekudzivirira armature wakaputirwa ne mica kekutanga.
(3) Mamwe magadzirirwo emagetsi emagetsi emazuva ano anoshandiswa, akadai sechimiro chakavharwa neamburera. Maseti masere ekutanga ndeechimiro umo matanda emagineti ari kunze (pivot type), uye maseti maviri ekupedzisira anochinjwa kuita chimiro chazvino umo matanda emagineti anotenderera mukati (field type).
(4) Modhi yekukurudzira yakasiyana. Yekutanga inoshandisa simba reDC rinogadzirwa nejenareta yemagetsi yemutsi yeDC iri pedyo kuti iite kuti iite. Mushure memakore maviri kana matatu, mayuniti ese achashandisa majenareta madiki emagetsi eDC semaexciter.
(5) Frequency ye25Hz yakagamuchirwa. Panguva iyoyo, Ying rate yeUnited States yaive yakasiyana-siyana, kubva pa16.67hz kusvika pa1000fhz. Mushure mekuongorora nekubvumirana, 25Hz yakagamuchirwa. Frequency iyi yave iri standard frequency mune dzimwe nzvimbo dzeUnited States kwenguva yakareba.
(6) Kare, magetsi aigadzirwa nemidziyo yekugadzira magetsi ainyanya kushandiswa pakugadzira magetsi, asi magetsi aigadzirwa nechiteshi chemagetsi cheNiagara Falls Adams ainyanya kushandiswa pakugadzira magetsi emaindasitiri.
(7) Kutakurwa kwemagetsi kwemagetsi emagetsi matatu-phase AC kwave kuonekwa kekutanga, izvo zvakaita basa rakanaka mukutakurwa kwemagetsi uye kushandiswa kwakakura kwemagetsi matatu-phase AC. Mushure memakore gumi ekushanda, mayuniti gumi ekugadzira magetsi emvura eAdams hydropower station akagadziridzwa zvizere uye akashandurwa. Mayuniti ese gumi akatsiviwa nemayuniti matsva e1000HP ne1200V, uye imwe yuniti itsva ye5000P yakaiswa, zvekuti huwandu hwese hwemagetsi hwaiswa hunosvika 105000hp.
Hondo ye AC yakananga ye hydro generator yakazokundwa ne AC. Kubva ipapo, simba re DC rakakanganiswa zvikuru, uye AC yakatanga kurira nekurwisa mumusika, izvo zvakagadzirawo nzira yekugadzirwa kwe hydro generators mune ramangwana. Zvisinei, zvakakosha kutaura kuti chinhu chinoshamisa chedanho rekutanga ndechekuti DC hydro generators dzinoshandiswa zvakanyanya. Panguva iyoyo, kwaive nemhando mbiri dze DC hydro motors. Rimwe i low-voltage generator. Majenareta maviri akabatana akatevedzana uye anofambiswa ne turbine imwe. Rechipiri i high-voltage generator, inova double pivot uye double pole generator inogovana shaft imwe. Ruzivo ruchaunzwa munyaya inotevera.
