Kev taw qhia txog asynchronous generators thiab synchronous generators
Qhov txawv ntawm generator asynchronous thiab synchronous generator yam:
Lawv tuaj yeem siv rau kev khiav haujlwm ntawm cov kiv cua kom ntev li ntev tau thaum siv cov khoom siv sib hloov.
Asynchronous generators yuav muab faib ua ntau hom raws li lawv tus qauv rotor:
(a) Cage asynchronous generator - lub rotor yog tawb hom. Vim hais tias cov qauv no yooj yim, txhim khu kev qha, pheej yig, thiab yooj yim mus nkag rau lub hwj chim, nws yog dav siv me me thiab nruab nrab cov chav nyob;
(b) Cov xov tooj txhuam raws li lub tshuab hluav taws xob (asynchronous generator) - lub rotor yog xaim hluav taws. Tus stator txuas ncaj qha mus rau kab sib chaws kom xa hluav taws xob, thiab lub rotor kiav txhab kuj tswj tau los ntawm cov khoom sib txuas rau kom xa tawm los yog tsis muaj zog los mus rau kab sib chaws.
Lub hom synchronous generator yam raws li cov hlau nplaum uas ua rau lub zog magnetic teb yuav ntxiv tau muab faib ua:
(a) Fais Excitation Synchronous Generator - Lub rotor yog ib lub xov tooj cua zom zaws uas tau zoo siab los ntawm ib sab nraud DC tam sim no los ua kom tau ib lub teb chaw magnetic.
(b) Cuamtshuab kev ua lag luam synchronous generator - Lub rotor yog ib qho chaw ruaj khov hlau uas ua los ntawm cov khoom ferrite, feem ntau qis qis ntau hom, uas tsis tas yuav tsum ua lwm tus excitation, uas simplifies cov qauv ntawm cov generator thiab yog li muaj ntau yam zoo.
