Yog tsis muaj lub zog ua kom lub zog AC hloov pauv yuav tsis muaj txoj hauv kev tsim nws qhov hluav taws xob thaum nws pib tig, thiab tsis tuaj yeem tswj nws qhov hluav taws xob mus rau qib pre-set nominal thaum khiav ntawm nws qhov ntsuas ceev. Yog li, tsis muaj qhov ua kom zoo siab, AC alternator yuav tsis muaj txiaj ntsig rau nws lub hom phiaj
Yuav ua li cas yog tias excitation tsis ua haujlwm?
Yog hais tias qhov excitation ntawm lub tshuab hluav taws xob tsis ua haujlwm, dheev yuav tsis muaj qhov sib nqus hlau nplaum ntxiv ntawm rotor thiab rotating magnetic teb ntawm statorTab sis tseem tus tswv xeev yuav muab tib lub zog rau lub tshuab hluav taws xob. rotor vim tam sim no sib nqus xauv; lub rotor yuav nrawm dua li synchronous ceev.
Lub hom phiaj ntawm kev txaus siab rau qhov hloov pauv yog dab tsi?
Lub hom phiaj tseem ceeb ntawm exciter hauv lub tshuab hluav taws xob (alternator) yog txhawm rau muab qhov chaw nyob ruaj khov rotating magnetic tebUas yog siv los ntxias cov e.m.f hauv armature coil. Yog li, DC lub zog yog muab rau exciter thiab lub exciter tsis muaj dab tsi tab sis ib kauj, thiab lub exciter tsim ib qho chaw sib nqus.
alternator excitation ua haujlwm li cas?
Lub tshuab ua kom lub zog tsim lub tshuab hluav taws xob hauv lub rotorLub stator muaj lub armature winding uas muaj hluav taws xob induced. Lub zog ntawm cov hlau nplaum tsim, lub zog hluav taws xob tsim tawm. Lub zog ntawm cov hlau nplaum yog kho los ntawm kev tswj cov tam sim no rau lub rotor.
Lub tsheb hloov pauv tus kheej puas txaus siab?
Thaum lub cav khiav thiab lub tshuab hloov hluav taws xob tsim hluav taws xob, lub diode pub lub teb tam sim no los ntawm cov khoom siv hluav taws xob tseem ceeb sib npaug ntawm qhov hluav taws xob thoob plaws qhov ntsuas ceeb toom uas tawm mus…. Qee lub alternators yuav ua rau nws tus kheej zoo siab thaum lub cav nce mus txog qhov ceev
