Izidingo Zezinga Lokushisa Lejeneretha kanye Nokupholisa

Njengomthombo wamandla ophuthumayo, ijeneretha yedizili idinga ukusebenza ngaphandle kokuphazamiseka isikhathi eside ngesikhathi sokusetshenziswa. Ngomthwalo omkhulu kangaka, izinga lokushisa le-generator liba yinkinga. Ukuze kugcinwe ukusebenza okuhle okungaphazanyiswa, izinga lokushisa kufanele ligcinwe ngaphakathi kwebanga elibekezelelekayo. Ngaphakathi kwalokhu, ngakho kufanele siqonde izidingo zokushisa nezindlela zokupholisa.

1. Izimfuneko zezinga lokushisa

Ngokwamabanga ahlukene wokufaka ama-insulation amajeneretha edizili, izidingo zokukhuphuka kwezinga lokushisa zihlukile. Ngokuvamile, izinga lokushisa le-stator winding, i-field winding, i-iron core, indandatho yokuqoqa cishe i-80 ° C lapho i-generator isebenza. Uma idlula, ithi Ukunyuka kwezinga lokushisa kuphezulu kakhulu.

2. Ukupholisa

Izinhlobo ezihlukene namandla amajeneretha anezinhlobo ezihlukene zokupholisa. Nokho, indawo yokupholisa esetshenziswa ngokuvamile umoya, i-hydrogen, namanzi. Thatha i-turbine synchronous generator njengesibonelo. Isistimu yayo yokupholisa ivaliwe, kanti indawo yokupholisa isetshenziswa ekujikelezeni.

① Ukupholisa umoya

Ukupholisa umoya kusebenzisa ifeni ukuthumela umoya. Umoya opholile usetshenziselwa ukushaya ukuphela kokujika kwejeneretha, i-generator stator kanye ne-rotor ukuze kukhishwe ukushisa. Umoya obandayo ubamba ukushisa bese uphenduka umoya oshisayo. Ngemva kokuhlanganisa, zikhishwa ngomgudu womoya wensimbi futhi zipholiswe ngesipholile. Umoya opholile ube usuthunyelwa kujeneretha ukuze ugaywe kabusha yisiphephetha-moya ukuze kufezwe injongo yokuqeda ukushisa. Amajeneretha ama-synchronous amaphakathi namancane ngokuvamile asebenzisa ukupholisa komoya.

② Ukupholisa i-hydrogen

Ukupholisa i-hydrogen kusebenzisa i-hydrogen njengendawo yokupholisa, futhi ukusebenza kokukhipha ukushisa kwe-hydrogen kungcono kunomoya. Isibonelo, amajeneretha amaningi e-turbo asebenzisa i-hydrogen ukupholisa.

③ Ukupholisa amanzi

Ukupholisa amanzi kusebenzisa indlela yokupholisa yangaphakathi ye-stator ne-rotor yamanzi aphindwe kabili. Amanzi abandayo esimiso samanzi e-stator ageleza esuka ohlelweni lwamanzi angaphandle ngokusebenzisa ipayipi lamanzi ukuya eringini yokungena kwamanzi efakwe ku-stator, bese egeleza kumakhoyili ngamapayipi afakwe i-insulated. Ngemva kokumunca ukushisa, kuqoqwa ipayipi lamanzi elifakwe e-insulated kuya kwendandatho yokuphuma kwamanzi efakwe kuhlaka. Bese ikhishelwa ohlelweni lwamanzi ngaphandle kwejeneretha ukuze iphole. Ukupholisa kwesistimu yamanzi e-rotor kuqala kungena kusekelo lokungena kwamanzi elifakwe ekugcineni kwe-shaft eseceleni ye-exciter, bese ligelezela embobeni emaphakathi ye-shaft ejikelezayo, ligeleza ngezimbobo ezimbalwa ze-meridional kuya ethangini lokuqoqa amanzi, bese ligelezela amakhoyili ngokusebenzisa ishubhu insulating. Ngemva kokuba amanzi abandayo emunca ukushisa, agelezela ethangini lokuphuma ngepayipi elivalekile, abese egelezela esisekelweni sokuphuma ngembobo yokukhipha amanzi emaphethelweni angaphandle ethangi lokuphuma, futhi aholele ngaphandle ngepayipi elikhulu lokuphuma. Njengoba ukusebenza kwamanzi okukhipha ukushisa kuphezulu kakhulu kunomoya ne-hydrogen, ijeneretha entsha enkulu ngokuvamile isebenzisa ukupholisa amanzi.
