Ijubane lokujikeleza kwama-hydraulic turbine liphansi kakhulu, ikakhulukazi kuma-hydraulic turbine aqondile. Ukuze kukhiqizwe i-alternating current engu-50Hz, i-hydraulic turbine generator isebenzisa isakhiwo sama-multiple pairs of magnetic poles. Ku-hydraulic turbine generator ene-revolutions engu-120 ngomzuzu, kudingeka ama-25 pairs of magnetic poles. Njengoba kunzima ukubona isakhiwo esine-magnetic poles eziningi kakhulu, leli phepha lethula imodeli ye-hydro-turbine generator ene-12 pairs of magnetic poles.
I-rotor ye-hydro-generator isebenzisa isakhiwo se-pole esiphawulekayo. Isithombe 1 sibonisa i-yoga kanye ne-magnetic pole ye-generator. I-magnetic pole ifakwe ku-magnetic joga. I-magnetic joga yindlela yomugqa wensimu yamagnetic we-magnetic pole. I-pole ngayinye iboshwe nge-excitation coil, futhi amandla okuvuselela anikezwa yi-excitation generator efakwe ekugcineni kwe-shaft eyinhloko, noma enikezwa uhlelo lwangaphandle lwe-thyristor excitation (olunikezwa yindandatho yokuqoqa ku-excitation coil).
Ijoka lifakwe ku-bracket ye-rotor, i-shaft enkulu yejenereyitha ifakiwe maphakathi ne-bracket ye-rotor, kanti i-generator yokuvuselela noma indandatho yokuqoqa ifakiwe ekugcineni okuphezulu kwe-shaft enkulu.
I-stator iron core yejenereyitha yenziwe ngamashidi ensimbi ye-silicon anomoya omuhle wamagnetic. Kunezikhala eziningi ezisatshalaliswa ngokulinganayo embuthanweni wangaphakathi we-iron core, ezisetshenziselwa ukufaka ama-stator coil.
Ama-stator coil afakwa ezikhaleni ze-stator ukuze akhe ama-winding ezigaba ezintathu, ukugoqa kwesigaba ngasinye kwakhiwe ngama-coil amaningi futhi kuhlelwe ngokwemithetho ethile.
I-hydro-generator ifakwe epanini lomshini elenziwe ngokhonkolo, kanti isisekelo somshini sifakwa epanini lomshini. Isisekelo somshini siyisisekelo sokufakwa kwe-stator iron core kanye negobolondo le-hydro-generator. Nciphisa izinga lokushisa lomoya opholile we-generator; uhlaka olungezansi lufakwe epanini, kanti uhlaka olungezansi lune-thrust bearing yokufaka i-generator rotor. I-thrust bearing ingamelana nesisindo se-rotor, ukudlidliza, umthelela kanye neminye imikhosi.
Faka umongo wensimbi ye-stator kanye nekhoyili ye-stator ohlakeni, i-rotor ifakwa phakathi kwe-stator, futhi kukhona isikhala esincane ne-stator. I-rotor isekelwa yi-thrust bearing yohlaka olungezansi futhi ingajikeleza ngokukhululeka. Faka uhlaka olungaphezulu, bese isikhungo sohlaka olungaphezulu sifakwe nge-. I-guide bearing ivimbela i-shaft eyinhloko yejenereyitha ukuthi inganyakaziswa futhi iyigcine izinzile endaweni ephakathi. Beka phansi kwepulatifomu ephezulu, faka idivayisi yebhulashi noma i-excitation motor, bese kufakwa imodeli ye-hydro-generator.
Ukujikeleza okukodwa kwe-rotor yemodeli ye-hydro-generator kuzodala imijikelezo eyi-12 yamandla e-electromotive e-AC anezigaba ezintathu. Lapho i-rotor ijikeleza ngokujikeleza okungu-250 ngomzuzu, imvamisa yamandla ashintshanayo ingu-50 Hz.
