E jiri ya tụnyere onye na-emepụta turbine uzuoku, hydro generator nwere njirimara ndị a:
(1) Ọsọ dị obere.Oke site na isi mmiri, ọsọ ntụgharị na-erughị 750r / min, ụfọdụ bụ naanị ọtụtụ mgbanwe mgbanwe kwa nkeji.
(2) Ọnụ ọgụgụ nke okporo osisi magnetik buru ibu.N'ihi na ọsọ ahụ dị ala, iji mepụta ike eletrik 50Hz, ọ dị mkpa ịbawanye ọnụ ọgụgụ nke oghere magnetik, nke mere na oghere magnetik nke ịkpụ stator winding ka nwere ike ịgbanwe ugboro 50 kwa nkeji.
(3) Ọdịdị ahụ buru ibu na nha na ibu.N'otu aka, ọsọ dị ala;N'aka nke ọzọ, ọ bụrụ na a jụrụ ibu nke unit ahụ, iji zere nkwụsị nke ọkpọkọ ígwè na-akpata site na hama mmiri siri ike, a na-achọ oge mmechi mberede nke vane ndu ka ọ dị ogologo, ma nke a ga-eme ka ịrị elu nke ngwa ngwa. unit ka ọ dị elu.Ya mere, a chọrọ rotor ka ọ nwee nnukwu ibu na inertia.
(4) A na-anabatakarị axis kwụ ọtọ.Iji belata ọrụ ala na ọnụ ahịa ihe ọkụkụ, ndị na-emepụta mmiri mmiri buru ibu na nke ọkara na-ejikarị ogwe kwụ ọtọ.
Enwere ike kewaa ndị na-emepụta mmiri mmiri n'ụdị kwụ ọtọ na nke kwụ ọtọ dị ka nhazi dị iche iche nke ogwe aka ha na-atụgharị: a na-ekewa ndị na-emepụta mmiri na-emepụta ihe n'ime ụdị nkwụsịtụ na nche anwụ dị ka ọnọdụ dị iche iche nke nbido ha si dị.
(1) Hydrogenerator kwụsịtụrụ.A na-etinye ihe ntinye aka na etiti ma ọ bụ akụkụ elu nke elu nke rotor, nke nwere ọrụ kwụsiri ike na nhazi dị mma, ma ịdị elu dị ukwuu na ntinye ego nke osisi buru ibu.
(2) Nchekwa hydro generator.A na-etinye ihe ntinye aka na etiti ahụ ma ọ bụ akụkụ elu nke etiti ala nke rotor.N'ozuzu, nnukwu hydro generators na ọkara na obere ọsọ kwesịrị ịnakwere nche anwụ ụdị n'ihi na ha nnukwu structural size, ka ibelata unit elu, zọpụta ígwè na ibelata osisi ego.N'ime afọ ndị na-adịbeghị anya, e mepụtara usoro nke ịwụnye ihe na-eme ka ọ dị n'elu mkpuchi nke turbine mmiri, a pụkwara ibelata ịdị elu nke unit ahụ.
2. Isi ihe
Ihe na-emepụta hydro generator bụ nke kachasị nke stator, rotor, strust bearing, n'elu na nke dị ala, ogwe elu na nke ala, ikuku ventilashion na ngwaọrụ jụrụ oyi, ngwaọrụ braking na ngwaọrụ mkpali.
(1) Stator.Ọ bụ akụkụ maka ịmepụta ike eletrik, nke mejupụtara winding, isi ígwè na shei.N'ihi na stator dayameta nke nnukwu na ọkara-sized hydro generators bụ nnọọ nnukwu, ọ bụ n'ozuzu mejupụtara nkebi nke njem.
(2) rotor.Ọ bụ akụkụ na-atụgharị na-emepụta oghere ndọta, nke nwere nkwado, mgbanaka wiil na ogwe ndọta.Mgbanaka wiil ahụ bụ ihe nwere ụdị mgbanaka nke efere ígwè nwere ụdị fan.A na-ekesa ogwe ndọta n'èzí mgbanaka wiil ahụ, a na-ejikwa mgbanaka wiil dị ka ụzọ nke oghere magnet.A na-agbakọta otu eriri nke rotor buru ibu na nke ọkara na saịtị, wee kpoo ọkụ na aka aka na isi ogwe nke generator.N'ime afọ ndị na-adịbeghị anya, a na-emepụta ihe owuwu nke rotor shaftless, ya bụ, a na-edozi nkwado rotor ozugbo na njedebe elu nke isi ogwe nke turbine.Ihe kachasị mma nke usoro a bụ na ọ nwere ike dozie nsogbu dị mma nke nnukwu ihe nkedo na forgings nke nnukwu unit kpatara;Na mgbakwunye, ọ nwekwara ike ibelata rotor na-ebuli ibu na ibuli elu, ka o wee belata osisi dị elu ma mee ka ụfọdụ akụ na ụba na-arụ ọrụ ike.
(3) Ntụnye aka.Ọ bụ akụkụ nke na-ebu ngụkọta arọ nke akụkụ na-agbagharị agbagharị nke otu na mkpali hydraulic axial nke turbine.
(4) Usoro oyi.Hydrogenerator na-ejikarị ikuku dị ka ihe jụrụ oyi iji mee ka stator, rotor winding na stator core dị jụụ.Ndị na-emepụta mmiri dị obere na-ejikarị ventilashị nke mepere emepe ma ọ bụ ọkpọkọ, ebe ndị na-emepụta mmiri mmiri buru ibu na ndị na-ajụkarị na-ejikarị ikuku mgbasa ozi nke onwe ha mechiri emechi.Iji meziwanye ike jụrụ oyi, ụfọdụ windings hydro generator na-arụ ọrụ dị elu na-anakwere ọnọdụ jụrụ oyi nke oghere oghere na-agafe n'ebe a na-ajụ oyi ozugbo, na usoro jụrụ oyi na-anabata mmiri ma ọ bụ usoro ọhụrụ.A na-eji mmiri na-eme ka stator na rotor windings dị n'ime ya, ihe na-ajụ oyi bụ mmiri ma ọ bụ ọkara ọhụrụ.A na-akpọ stator na rotor windings nke na-eme ka mmiri dị n'ime ụlọ jụrụ oyi okpukpu abụọ.A na-akpọ stator na rotor windings na stator core nke na-anakwere mmiri jụrụ oyi bụ mmiri zuru oke n'ime ime, mana stator na rotor windings nke na-eme ka mmiri dị n'ime mmiri na-akpọ mmiri jụrụ oyi.
Ụzọ ọzọ jụrụ oyi nke hydro generator bụ evaporative jụrụ, nke na-ejikọta mmiri mmiri n'ime onye nduzi nke hydro generator maka evaporative jụrụ.Evaporative jụrụ oyi nwere uru na thermal conductivity nke ihe jụrụ oyi dị ukwuu karịa nke ikuku na mmiri, ma nwee ike ibelata ibu na nha nke unit ahụ.
(5) The excitation ngwaọrụ na ya mmepe bụ isi dị ka nke thermal ike nkeji.
