Isivinini samaturbines amanzi siphansi, ikakhulukazi i-turbine yamanzi emile.Ukuze kukhiqizwe i-50Hz AC, ijeneretha ye-turbine yamanzi isebenzisa ukwakheka kwezigxobo ezihlukene kazibuthe.Kujeneretha ye-turbine yamanzi ene-revolution engu-120 ngomzuzu, amapheya angu-25 ezigxobo kazibuthe ayadingeka.Ngenxa yokuthi kunzima ukubona ukwakheka kwezigxobo kazibuthe eziningi kakhulu, le courseware yethula imodeli ye-hydraulic turbine generator enamapheya angu-12 ezigxobo kazibuthe.
I-rotor ye-hydro generator isebenzisa ukwakheka kwesigxobo esibalulekile.Umfanekiso 1 ubonisa ijoka kazibuthe kanye nesigxobo kazibuthe se-generator.Isigxobo kazibuthe sifakwe ejokeni kazibuthe, okuyindlela yomugqa wensimu kazibuthe yesigxobo kazibuthe.Imodeli yejeneretha inezigxobo kazibuthe ezingu-24 phakathi kweNyakatho neningizimu, futhi isigxobo ngasinye sikazibuthe sinenxeba ngekhoyili evusa amadlingozi.Amandla avusa amadlingozi anikezwa ijeneretha evusa amadlingozi efakwe ekugcineni kwe-shaft eyinhloko noma uhlelo lwe-excitation lwe-thyristor lwangaphandle (indandatho yokuqoqa inikeza amandla kukhoyili yokuvusa).
Ijoka lamagnetic lifakwe ekusekelweni kwe-rotor, i-shaft eyinhloko ye-generator ifakwe phakathi nendawo yokusekelwa kwe-rotor, futhi i-generator yokuvuselela noma indandatho yokuqoqa ifakwe ekugcineni okuphezulu kwe-shaft enkulu.
I-generator stator core yenziwe ngamashidi ensimbi ye-silicon ane-conductivity kazibuthe enhle, futhi izikhala eziningi zisakazwa ngokulinganayo kumbuthano ongaphakathi womongo ukuze ushumeke ikhoyili ye-stator.
Ikhoyili ye-stator ishumekwe ku-stator slot ukuze yakhe ukuphenduka kwezigaba ezintathu.Ukusonteka kwesigaba ngasinye kwakhiwe ngamakhoyili amaningi futhi ahlelwa ngokomthetho othile.
I-hydro generator ifakwe ku-pier ye-turbine ethela ukhonkolo, futhi i-turbine pier ifakwe nesisekelo se-turbine.Isizinda se-turbine yisisekelo sokufakwa kwe-stator core kanye negobolondo le-hydro generator.Idivayisi yokukhipha ukushisa ifakwe egobolondweni lesizinda se-turbine ukunciphisa izinga lokushisa lomoya opholile we-generator;Uhlaka olungezansi nalo lufakwe ku-pier.Uhlaka olungezansi lufakwe i-thrust bear, esetshenziselwa ukufaka i-rotor ye-generator.I-thrust bear ithwala isisindo, ukudlidliza, umthelela kanye namanye amandla e-rotor.
Ikhoyili ye-stator kanye nekhoyili ye-stator ifakwe esisekelweni.I-rotor ifakwe phakathi kwe-stator futhi ine-gap encane ne-stator.I-rotor isekelwa i-thrust bear yohlaka oluphansi futhi ingajikeleza ngokukhululekile.Kufakwe ifreyimu engaphezulu, futhi i-guide bear ifakwe phakathi nendawo yefreyimu engaphezulu ukuze kuvinjwe i-shaft eyinhloko ye-generator ukuthi inganyakazi futhi igcinwe endaweni emaphakathi ngokuzinzile.Ngemva kokubeka indawo engaphezulu yesikhulumi nokufaka idivayisi yebhulashi noma injini evusa amadlingozi, kufakwa imodeli ye-hydro generator.
Amandla e-electromotive ezigaba ezintathu ze-AC yemijikelezo engu-12 azobangelwa ukuzungezisa kwemodeli yerotha yejeneretha yamanzi.Uma isivinini se-rotor singama-revolutions angu-250 ngomzuzu, imvamisa ye-AC ekhiqiziwe ingu-50 Hz.
