Hydrogenerator bụ obi ọdụ ụgbọ mmiri.Ngalaba na-emepụta turbine mmiri bụ akụrụngwa kachasị mkpa nke ụlọ ọrụ ike mmiri.Ọrụ nchekwa ya bụ ihe dị mkpa na-ekwe nkwa maka ụlọ ọrụ ike mmiri iji hụ na nchekwa, ịdị mma na ike akụ na ụba na ọkọnọ, nke metụtara ọrụ nchekwa na kwụsiri ike nke grid ọkụ.Ebe a na-arụ ọrụ nke igwe na-emepụta ihe na-emepụta mmiri na-ejikọta ya na ahụike na ndụ ọrụ nke unit generator.Nke a bụ usoro ndị e mere iji kwalite gburugburu ọrụ generator dabere na ọdụ ụgbọ mmiri Xiaowan.
Ịjụ ọgwụgwọ mmanụ nke tankị mmanụ
Ọjụjụ mmanụ a jụrụ na-ebu ibu ga-emerụ ihe na-emepụta mmiri na akụrụngwa inyeaka ya.Otu Xiaowan enweela nsogbu site na ịjụ mmanụ n'ihi oke ọsọ ya.Ọjụjụ mmanụ nke Xiaowan na-ebu ibu bụ ihe atọ kpatara: mmanụ na-akpụ akpụ nke njikọ njikọ dị n'etiti isi ihe na rotor center, mmanụ na-arị arị elu nke mkpuchi mkpuchi elu nke efere mmanụ, na nkwụsị nke " t” akara n'etiti akara nkwonkwo gbawara agbawa nke efere mmanụ a na-etinye na akara anular nke ala.
Ụlọ ọrụ ike ahụ ahazila oghere mkpuchi n'elu njikọ dị n'etiti isi ihe na-eme ka isi na rotor center ahụ, tinye 8 eriri roba na-eguzogide mmanụ, gbochie oghere pin na rotor center ahụ, dochie efere mkpuchi mbụ nke elu nke efere mmanụ na-agbanye mmanụ. ihe mkpuchi mkpuchi mmanụ kọntaktị nwere eriri mkpuchi na-esochi, ma tinye akara n'elu kọntaktị zuru ezu nke nkwonkwo gbawara agbawa nke efere mmanụ.Ka ọ dị ugbu a, a doziela ihe na-atụfu mmanụ nke olulu mmanụ nke ọma.
Mgbanwe ikuku nke ọwara ikuku generator
Irigi condensation na generator ifufe ọwara nke n'okpuru ala powerhouse na South China bụ a na-ahụkarị na siri ike dozie, nke nwere mmetụta kpọmkwem na mkpuchi nke generator stator, rotor na ya ihe enyemaka akụrụngwa.Xiaowan ga-eme ihe iji hụ na akara a pụrụ ịdabere na ya n'etiti ọwara ikuku generator na n'èzí, ma gbakwunye mkpuchi condensation na pipeline mmiri niile na ọwara ikuku generator.
A na-agbanwe ikuku ikuku dị ala nke mbụ ka ọ bụrụ ike dị elu mechiri emechi kpamkpam.Mgbe emechiri, iru mmiri dị na ọwara ikuku generator nwere ike ịchịkwa nke ọma n'okpuru 60%.Enweghị condensation na generator ikuku oyi na mmiri usoro pipelines na ikuku ọwara, nke ọma na-egbochi corrosion nke generator stator core na mmiri nke dị mkpa eletriki akụrụngwa na components, na-eme ka a na-arụ ọrụ nkịtị nke generator.
Ngbanwe nke breeki ebule
Uzuzu nke ebule na-emepụta n'oge braking generator bụ isi iyi mmetọ na-akpata mmetọ stator na rotor.Ọdụ ụgbọ mmiri Xiaowan jiri ebule na-enweghị uzuzu na-abụghị ọla dochie ebule breeki mbụ.Ka ọ dị ugbu a, ọnweghị uzuzu doro anya n'oge braking na-emechi generator, yana mmetụta nkwalite ahụ pụtara ìhè.
Ndị a bụ usoro nke Xiaowan Hydropower Station mere iji melite ma melite gburugburu ebe ọrụ generator.N'ime narị afọ nkwalite na nkwalite ọrụ gburugburu ọdụ ụgbọ mmiri, anyị kwesịrị iji sayensị na ezi uche chepụta atụmatụ nkwalite ahụ dabere na ọnọdụ ahụ akọwapụtara nke ọma, nke enweghị ike ịkọwapụta ya.
