Poyerekeza ndi jenereta ya turbine ya nthunzi, jenereta ya hydro ili ndi izi:
(1) Liwiro ndilochepa.Zochepa ndi mutu wamadzi, liwiro lozungulira nthawi zambiri limakhala lochepera 750r / min, ndipo zina zimangosintha kambiri pamphindi.
(2) Chiwerengero cha mitengo ya maginito ndi yaikulu.Chifukwa liwiro ndi otsika, kuti kupanga 50Hz mphamvu yamagetsi, m'pofunika kuonjezera chiwerengero cha mitengo maginito, kotero kuti maginito odula stator mapindikidwe akadali kusintha 50 pa sekondi.
(3) Kapangidwe kake ndi kakukulu ndi kulemera kwake.Kumbali imodzi, liwiro ndi lochepa;Komano, ngati katundu kukanidwa wa unit, pofuna kupewa kupasuka kwa chitsulo chitoliro chifukwa champhamvu madzi nyundo, mwadzidzidzi kutseka nthawi ya kalozera vane ayenera kukhala yaitali, koma izi zidzachititsa kukwera liwiro la unit kuti ikhale yokwera kwambiri.Choncho, rotor imayenera kukhala ndi kulemera kwakukulu ndi inertia.
(4) Mzere wolunjika umatengedwa nthawi zambiri.Pofuna kuchepetsa kukwera kwa nthaka ndi mtengo wa zomera, majenereta akuluakulu ndi apakatikati a hydro nthawi zambiri amagwiritsa ntchito shaft yoyima.
Majenereta a Hydro amatha kugawidwa m'mitundu yoyima komanso yopingasa molingana ndi makonzedwe osiyanasiyana a ma shaft awo ozungulira: ma jenereta oyimirira a hydro amatha kugawidwa m'mitundu yoyimitsidwa ndi maambulera malinga ndi malo osiyanasiyana amayendedwe awo.
(1) Kuyimitsidwa kwa Hydrogenerator.Kuwongolera kumayikidwa pakatikati kapena kumtunda kwa chimango chapamwamba cha rotor, chomwe chimakhala ndi ntchito yokhazikika komanso yokonza bwino, koma kutalika kwake ndi kwakukulu ndipo ndalama zogulira mbewu zimakhala zazikulu.
(2) Umbrella hydro jenereta.Kuwongolera kumayikidwa pakati pa thupi kapena kumtunda kwa chimango chapansi cha rotor.Nthawi zambiri, majenereta akuluakulu a hydro okhala ndi liwiro lapakati komanso otsika ayenera kutengera mtundu wa ambulera chifukwa cha kukula kwawo kwakukulu, kuti achepetse kutalika kwa unit, kupulumutsa chitsulo ndikuchepetsa ndalama zobzala.M'zaka zaposachedwa, mapangidwe oyikapo chivundikiro chapamwamba cha turbine yamadzi apangidwa, ndipo kutalika kwa unit kumatha kuchepetsedwa.
2. Zigawo zazikulu
Jenereta ya Hydro imapangidwa makamaka ndi stator, rotor, thrust bear, mayendedwe apamwamba ndi otsika, mafelemu apamwamba ndi apansi, mpweya wabwino ndi chipangizo chozizirira, chipangizo cha braking ndi chipangizo chosangalatsa.
(1) Sintha.Ndi gawo lopangira mphamvu yamagetsi, yomwe imapangidwa ndi mafunde, chitsulo pakati ndi chipolopolo.Chifukwa kukula kwa stator kwa majenereta akulu ndi apakatikati a hydro ndi akulu kwambiri, nthawi zambiri amakhala ndi magawo oyendera.
(2) Rota.Ndi gawo lozungulira lomwe limapanga mphamvu ya maginito, yomwe imakhala ndi chithandizo, mphete yamagudumu ndi maginito.Chigudulicho ndi chinthu chooneka ngati mphete chopangidwa ndi mbale zachitsulo zooneka ngati fan.Mitengo ya maginito imagawidwa kunja kwa gudumu, ndipo mphete ya magudumu imagwiritsidwa ntchito ngati njira ya maginito.Chingwe chimodzi cha rotor yayikulu komanso yaying'ono imasonkhanitsidwa pamalopo, kenako imatenthedwa ndikuyika manja pa shaft yayikulu ya jenereta.M'zaka zaposachedwa, mawonekedwe a rotor shaftless apangidwa, ndiko kuti, chithandizo cha rotor chimakhazikitsidwa mwachindunji kumapeto kwa shaft yaikulu ya turbine.Ubwino waukulu wa kapangidwe kameneka ndikuti ukhoza kuthetsa mavuto amtundu wa castings zazikulu ndi zokopa zomwe zimayambitsidwa ndi gawo lalikulu;Kuphatikiza apo, imathanso kuchepetsa kulemera kwa rotor ndikukweza kutalika, kuti muchepetse kutalika kwa mbewu ndikubweretsa chuma china pakumanga kwamagetsi.
(3) Kukankha.Ndi gawo lomwe limanyamula kulemera kwathunthu kwa gawo lozungulira la unit ndi axial hydraulic thrust ya turbine.
(4) Dongosolo lozizira.Hydrogenerator nthawi zambiri imagwiritsa ntchito mpweya ngati sing'anga yozizira kuziziritsa stator, kuzungulira kwa rotor ndi stator core.Majenereta ang'onoang'ono a hydro nthawi zambiri amatenga mpweya wotseguka kapena wa chitoliro, pomwe majenereta akulu ndi apakatikati a hydro nthawi zambiri amatenga mpweya wotsekeka wodziyendetsa.Pofuna kupititsa patsogolo kuzirala, ma windings ena apamwamba kwambiri a hydro jenereta amatengera njira yozizirira yamkati ya kondakitala ya dzenje yomwe imadutsa m'malo ozizira, ndipo sing'anga yozizira imatenga madzi kapena sing'anga yatsopano.Ma stator ndi rotor windings amakhazikika mkati mwa madzi, ndipo malo ozizira ndi madzi kapena sing'anga yatsopano.Mapiritsi a stator ndi rotor omwe amatenga kuziziritsa mkati mwa madzi amatchedwa kuzizira kwapakati pawiri.Ma stator ndi rotor windings ndi stator core omwe amatengera kuziziritsa kwa madzi amatchedwa kuziziritsa kwamadzi mkati mwamadzi, koma mafunde a stator ndi rotor omwe amatengera kuziziritsa kwamkati kwamadzi amatchedwa kuziziritsa kwamkati kwamadzi.
Njira ina yozizira ya jenereta ya hydro ndi kuzirala kwa evaporative, komwe kumalumikiza sing'anga yamadzi mu kondakita wa hydro jenereta kuti muziziritsa evaporative.Kuzizira kwa evaporative kuli ndi ubwino wake kuti kutentha kwa sing'anga yozizira kumakhala kwakukulu kwambiri kuposa mpweya ndi madzi, ndipo kungachepetse kulemera ndi kukula kwa unit.
(5) Chipangizo chotsitsimutsa ndi chitukuko chake ndizofanana ndi zamagulu amagetsi otentha.
