Nke mbụ, anyị kwesịrị ịkpa oke n'okwu a iji zere ime ka ọ ghara ịdị oke nkọ. Generator a kọwara ebe a na-ezo aka na jenerato AC nke na-enweghị brush, nke nwere usoro atọ, nke a na-akpọ naanị "generator".
Ụdị jenereta a nwere opekata mpe akụkụ atọ bụ isi, nke a ga-ekwu maka ya na mkparịta ụka na-esonụ:
Isi jenerato, nke kewara n'ime isi stator na isi rotor; Isi rotor na-enye ubi magnet, isi stator na-emepụta ọkụ eletrik iji nye ibu; Ihe na-eme ka ihe ... ghara ịdị mma; Isi rotor na-enye ebe a na
Nkọwa nke ọrụ nhazi voltaji AVR
Ebumnobi ọrụ nke AVR bụ ịnọgide na-enwe voltaji mmepụta nke jenerato kwụsiri ike, nke a na-akpọkarị "onye na-eme ka voltaji guzosie ike".
Ọrụ ya bụ ịbawanye ọkụ eletrik nke ihe na-akpali akpali mgbe voltaji mmepụta nke ihe na-emepụta ihe dị ala karịa uru edobere, nke yiri mmụba ọkụ eletrik nke rotor bụ isi, na-eme ka voltaji ihe na-emepụta ihe bụ isi rịgoro na uru edobere; N'ụzọ megidere nke ahụ, belata ọkụ eletrik ma kwe ka voltaji ahụ belata; Ọ bụrụ na voltaji mmepụta nke ihe na-emepụta ihe hà nhata na uru edobere, AVR na-edobe mmepụta dị ugbu a na-enweghị mgbanwe.
Ọzọkwa, dịka mmekọrịta dị n'etiti ugbu a na voltaji si dị, enwere ike kewaa ibu AC n'ime ụdị atọ:
Ibu mgbochi, ebe ọkụ eletrik dị na usoro yana voltaji etinyere ya; Ibu mgbochi, usoro nke ọkụ eletrik na-agbada n'azụ voltaji; Ibu mgbochi, usoro nke ọkụ eletrik na-aga n'ihu voltaji. Ntụnyere nke njirimara ibu atọ na-enyere anyị aka ịghọta ibu mgbochi.
Maka ibu ndị na-eguzogide ọgwụ, ibu ibu ka ibu ahụ na-ebu ibu, otú ahụ ka ọkụ ọkụ mkpali dị mkpa maka rotor bụ isi (iji mee ka voltaji mmepụta nke jenerato ahụ kwụsie ike).
N'okwu na-esote, anyị ga-eji ọkụ mkpali achọrọ maka ibu resistive dị ka ọkọlọtọ ntụaka, nke pụtara na a na-akpọ ndị buru ibu dị ka ndị buru ibu; Anyị na-akpọ ya obere karịa ya.
Mgbe ibu nke jenereta ahụ bụ inductive, rotor bụ isi ga-achọ ka ọkụ ọkụ na-akpali akpali ka jenereta ahụ wee nwee ike ịnọgide na-enwe voltaji mmepụta kwụsiri ike.
Ibu ike
Mgbe generator ahụ zutere ibu ike, ọkụ ọkụ ọkụ nke rotor bụ isi chọrọ na-adị obere, nke pụtara na a ga-ebelata ọkụ ọkụ ọkụ iji mee ka voltaji mmepụta nke generator ahụ kwụsie ike.
Gịnị mere nke a ji mee?
Anyị kwesịrị icheta na ọkụ eletrik dị na ibu capacitive dị n'ihu voltaji, ọkụ eletrik ndị a na-eduga (na-agafe na stator bụ isi) ga-emepụta ọkụ eletrik na rotor bụ isi, nke a na-ejikọta ya na ọkụ eletrik na-akpali akpali, na-eme ka oghere magnetik nke rotor bụ isi dịkwuo mma. Ya mere, a ga-ebelata ọkụ eletrik sitere na ihe na-akpali akpali iji nọgide na-enwe voltaji mmepụta kwụsiri ike nke jenereta.
Ka ibu capacitive buru ibu, otú ahụ ka mmepụta nke ihe na-akpali akpali si dị obere; Mgbe ibu capacitive mụbara ruo n'ókè ụfọdụ, a ga-ebelata mmepụta nke ihe na-akpali akpali ka ọ bụrụ efu. Mmepụta nke ihe na-akpali akpali bụ efu, nke bụ oke nke ihe na-akpali akpali; N'oge a, voltaji mmepụta nke ihe na-akpali akpali agaghị eguzosi ike n'onwe ya, ụdị ike a erughịkwa eru. A makwaara mmachi a dị ka 'n'okpuru mmachi mkpali'.
Ihe na-enye jenereta ahụ nwere ike ịnabata naanị oke ibu; (N'ezie, maka jenereta akọwapụtara, enwerekwa oke na nha ibu resistive ma ọ bụ inductive.)
Ọ bụrụ na ọrụ nwere nsogbu site na ibu ike, o kwere omume ịhọrọ iji isi mmalite ike IT nwere obere ikike kwa kilowatt, ma ọ bụ jiri inductor maka ụgwọ ọrụ. Ekwela ka set jenereta rụọ ọrụ nso mpaghara "n'okpuru oke mkpali".
