Amanyathelo eNdibano kunye nokuFakela iZilumkiso ze-Hydro Generator

Isantya see turbines zamanzi sisezantsi kakhulu, ngakumbi i-injini yamanzi eme nkqo. Ukwenzela ukuvelisa i-50Hz AC, ijenereyitha yeijinijeyitha yamanzi ithatha iperi ye-multiple magnetic pole structure. Kwijenereyitha ye-iturbine yamanzi ene-120 revolutions ngomzuzu, iipere ezingama-25 zeepali zemagneti ziyafuneka. Kuba kunzima ukubona ulwakhiwo lweepali zemagnethi ezininzi, le courseware yazisa imodeli ye hydraulic turbine generator enepere ezili-12 zeepali zemagnethi.

I-rotor ye-hydro generator ithatha isakhiwo sepali esibalulekileyo. Umzobo we-1 ubonisa ijoka yamagnetic kunye ne-pole magnetic ye-generator. Ipoleni yamagnetic ifakwe kwijoka yamagnetic, eyona ndlela yomgca wemagnethi wepoleni yamagnetic. Imodeli yejenereyitha ineepali zemagneti ezingama-24 phakathi kweNyakatho nasezantsi, kwaye ipoleni nganye yamagnetic inxeba nge-coil yokuvuselela. Amandla okuvuselela anikezelwa yi-generator yokuvuselela efakwe ekupheleni kwe-shaft engundoqo okanye nge-excitation system ye-thyristor yangaphandle (umqokeleli we-ring inika amandla kwi-coil excitation).

Ijoka lamagnetic lifakwe kwinkxaso ye-rotor, i-shaft engundoqo ye-generator ifakwe phakathi kwenkxaso ye-rotor, kwaye i-generator ye-excitation okanye i-collector ring ifakwe ekupheleni okuphezulu kwe-shaft enkulu.

Undoqo we-stator wejenereyitha wenziwa ngamashiti ensimbi ye-silicon ene-conductivity entle yemagnethi, kwaye iindawo ezininzi zokubeka i-slots zisasazwa ngokulinganayo kwisangqa sangaphakathi sombindi ukushumeka ikhoyili yestator.

I-coil ye-stator ifakwe kwi-slot ye-stator ukuze yenze i-wing phase-phase. Ukujika kwesigaba ngasinye kuqulunqwe ngeekhoyili ezininzi kwaye zicwangciswe ngokomthetho othile.

Ijenereyitha ye-hydro ifakwe kwi-concrete yokugalela i-turbine pier, kwaye i-iturbine pier ifakwe kunye nesiseko se-iturbine. Isiseko se turbine sisiseko sofakelo londoqo westator kunye neqokobhe lejenereyitha yehydro. Isixhobo sokuphelisa ubushushu sifakwe kwiqokobhe lesiseko se turbine ukunciphisa ubushushu bomoya opholileyo wejenereyitha; Isakhelo esisezantsi sikwafakwe kwi-pier. Isakhelo esisezantsi sixhotyiswe nge-thrust bear, esetyenziselwa ukufaka i-rotor generator. I-thrust bearing ingathwala ubunzima, ukungcangcazela, impembelelo kunye neminye imikhosi ye-rotor.

I-stator core kunye ne-stator coil ifakwe kwisiseko. I-rotor ifakwe phakathi kwe-stator kwaye ine-gap encinci kunye ne-stator. I-rotor ixhaswa yi-thrust bearing yesakhelo esisezantsi kwaye inokujikeleza ngokukhululekileyo. Isakhelo esiphezulu sifakwe, kwaye isikhokelo sifakwe phakathi kwesakhelo esiphezulu ukukhusela i-shaft ephambili yejeneretha ukuba ishukume kwaye igcinwe kwindawo ephakathi ngokuzinzileyo. Emva kokubeka umgangatho ophezulu weqonga kunye nokufaka isixhobo sebrashi okanye i-motor excitation, imodeli ye-hydro generator ifakwe.

Isigaba sesithathu se-AC electromotive force ye-12 cycles iya kubangelwa ukujikeleza kwemodeli ye-rotor ye-hydro generator. Xa isantya se-rotor si-250 revolutions ngomzuzu, i-frequency ye-AC eyenziwe yi-50 Hz.
