Isantya sokujikeleza kweeinjini zehydraulic sisezantsi kakhulu, ngakumbi kwiiinjini zehydraulic ezithe nkqo. Ukuze kuveliswe i-50Hz etshintshanayo yangoku, ijenereyitha ye-hydraulic turbine ithatha ubume bepere ezininzi zeepali zemagnethi. Kwijenereyitha ye-injini ye-hydraulic ene-120 revolutions ngomzuzu, iipere ezingama-25 zeepali zemagneti ziyafuneka. Ekubeni kunzima ukubona isakhiwo esinezibonda ezininzi zemagnethi, eli phepha lazisa imodeli yejenereyitha ye-hydro-turbine ene-12 iperi ye-magnetic poles.
I-rotor ye-hydro-generator ithatha isakhiwo esibalulekileyo se-pole. Umzobo we-1 ubonisa ijoka kunye ne-pole magnetic ye-generator. Ipoleni yamagnetic ifakwe kwidyokhwe yamagnetic. Idyokhwe yamagnetic yindlela yomgca wemagnethi wepoleni yamagnetic. Ipali nganye inxeba nge-coil yokuvuselela, kwaye amandla okuvuselela anikezelwa yi-generator ye-excitation efakwe ekupheleni kwe-shaft engundoqo, okanye ibonelelwe yinkqubo yokuvuselela i-thyristor yangaphandle (enikezelwa ngumqokeleli kwi-coil yokuvuselela).
Ijoka ifakwe kwi-rotor bracket, i-shaft engundoqo ye-generator ifakwe phakathi kwe-rotor bracket, kwaye i-generator yokuvuselela okanye i-ring collector ifakwe kwindawo ephezulu ye-shaft enkulu.
I-stator iron core ye-generator yenziwe ngamashiti ensimbi ye-silicon ene-conductivity enhle yamagnetic. Kukho iindawo zokubeka ezininzi ezisasazwa ngokulinganayo kwisangqa sangaphakathi sombindi wentsimbi, ezisetyenziselwa ukushumeka iikhoyili zestator.
Iikhoyili ze-stator zifakwe kwiindawo zokubeka i-stator ukwenza i-wind-phase windings, isigaba ngasinye somoya siqulunqwe ngee-coil ezininzi kwaye zihlelwe ngokwemigaqo ethile.
I-hydro-generator ifakwe kwi-pier yomatshini eyenziwe ngekhonkrithi, kwaye isiseko somatshini sifakwe kwi-pier machine. Isiseko somatshini sisisiseko sokufakela isiseko sensimbi ye-stator kunye negobolondo ye-hydro-generator. Ukunciphisa ubushushu bomoya opholileyo wejenereyitha; isakhelo esisezantsi sikwafakwe kwi-pier, kwaye isakhelo esisezantsi sine-thrust bear yokufaka i-rotor ye-generator. I-thrust bearing inokumelana nobunzima be-rotor, i-vibration, impembelelo kunye namanye amandla.
Faka i-stator iron core kunye ne-stator coil kwisakhelo, i-rotor ifakwe phakathi kwe-stator, kwaye kukho i-gap encinci kunye ne-stator. I-rotor ixhaswa yi-thrust bearing yesakhelo esisezantsi kwaye inokujikeleza ngokukhululekileyo. Faka isakhelo esiphezulu, kwaye umbindi wesakhelo esiphezulu ufakwe kunye nesikhokelo sokuthwala sithintela i-shaft ephambili yejeneretha ukuba ishukume kwaye igcine ngokuzinzileyo kwindawo ephakathi. Beka umgangatho ophezulu weqonga, faka isixhobo sebrashi okanye i-motor excitation, kwaye imodeli ye-hydro-generator ifakwe.
Ukujikeleza okukodwa kwe-rotor yemodeli ye-hydro-generator kuya kubangela imijikelo ye-12 yesigaba sesithathu samandla ombane we-AC. Xa i-rotor ijikeleza kwii-revolutions ezingama-250 ngomzuzu, i-frequency ye-alternating current yi-50 Hz.
