Isivinini sokujikeleza sama-hydraulic turbines siphansi uma kuqhathaniswa, ikakhulukazi kuma-vertical hydraulic turbines.Ukuze ukhiqize amandla ashintshayo angu-50Hz, ijeneretha ye-hydraulic turbine isebenzisa ukwakheka kwamapheya amaningi ezigxobo kazibuthe.Kujeneretha ye-hydraulic turbine ene-revolution engu-120 ngomzuzu, amapheya angu-25 ezigxobo kazibuthe ayadingeka.Njengoba kunzima ukubona isakhiwo esinezigxobo kazibuthe eziningi kakhulu, leli phepha lethula imodeli yejeneretha ye-hydro-turbine enamapheya angu-12 ezigxobo kazibuthe.
I-rotor ye-hydro-generator yamukela ukwakheka kwesigxobo esibucayi.Umfanekiso 1 ubonisa ijoka kanye nesigxobo kazibuthe sejeneretha.I-pole magnetic ifakwe ejokeni lamagnetic.Ijoka kazibuthe yindlela yomugqa wensimu kazibuthe yesigxobo kazibuthe.Isigxobo ngasinye silinyazwa ngekhoyili evusa amadlingozi, futhi amandla avusa amadlingozi anikezwa ijeneretha evusa amadlingozi efakwe ekugcineni kwe-shaft eyinhloko, noma ehlinzekwe isistimu ye-excitation ye-thyristor yangaphandle (ehlinzekwa yindandatho yomqoqi kwikhoyili yokuvusa).
Ijoka lifakwe kubakaki be-rotor, i-shaft eyinhloko ye-generator ifakwe phakathi nendawo ye-rotor bracket, futhi i-generator ye-excitation noma indandatho yokuqoqa ifakwe ekugcineni okuphezulu kwe-shaft enkulu.
I-stator iron core ye-generator yenziwe ngamashidi ensimbi ye-silicon ane-conductivity enhle kazibuthe.Kunezikhala eziningi ezisatshalaliswe ngokulinganayo endingilizini yangaphakathi yensimbi, esetshenziselwa ukushumeka amakhoyili e-stator.
Amakhoyili e-stator ashumekwe ezikhaleni ze-stator ukuze enze ama-windings ezigaba ezintathu, isigaba ngasinye sakhiwe ngamakhoyili amaningi futhi ahlelwe ngokuvumelana nemithetho ethile.
I-hydro-generator ifakwe ku-pier yomshini eyenziwe ngokhonkolo, futhi isisekelo somshini sifakwe kumshini womshini.Isisekelo somshini siyisisekelo sokufakwa kwe-stator iron core kanye negobolondo le-hydro-generator.Yehlisa izinga lokushisa lomoya opholile wejeneretha;ifreyimu ephansi nayo ifakwe ku-pier, futhi ifreyimu engezansi ine-thrust bear ukufaka i-rotor ye-generator.I-thrust bear ingakwazi ukumelana nesisindo se-rotor, ukudlidliza, umthelela namanye amandla.
Faka i-stator iron core kanye nekhoyili ye-stator kuhlaka, i-rotor ifakwe phakathi kwe-stator, futhi kukhona igebe elincane ne-stator.I-rotor isekelwa i-thrust bear yohlaka oluphansi futhi ingajikeleza ngokukhululekile.Faka uhlaka olungaphezulu, futhi isikhungo sefreyimu engenhla sifakwe ne-guide bear ivimbela i-shaft eyinhloko ye-generator ukuthi inganyakazi futhi iyigcine iqinile endaweni ephakathi.Beka isiteji esingaphezulu, faka idivayisi yebhulashi noma injini evusa amadlingozi, bese kufakwa imodeli ye-hydro-generator.
Ukuzungezisa okukodwa kwerotha yemodeli ye-hydro-generator kuzodala imijikelezo engu-12 yamandla e-AC electromotive ezigaba ezintathu.Lapho i-rotor ijikeleza ngo-250 revolutions ngomzuzu, imvamisa ye-alternating current ingu-50 Hz.
