Qhov siv dav tshaj plaws xws li lub tshuab ua lub tshuab synchronous yog nyob rau hauv kev lag luam, qhov twg muaj hluav taws xob tsav ua haujlwm ntawm qhov ceev tsis tu ncua. Piv txwv li, compressors nrog lub cev muaj zog, twj tso kua mis. Tsis tas li ntawd, lub tshuab synchronous yog ib feem tseem ceeb ntawm ntau yam khoom siv hauv tsev, piv txwv li, nws yog nyob rau hauv watches.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab no yooj yim heev. Kev sib cuam tshuam ntawm kev sib nqus sib nqus ntawm lub armature, tsim los ntawm alternating tam sim no, thiab cov magnetic teb ntawm tus ncej ntawm inductor, tsim los ntawm cov tam sim no ncaj qha, underlies lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm xws li ib tug hluav taws xob ntaus ntawv raws li ib tug synchronous lub cev muaj zog. Feem ntau, lub inductor nyob rau ntawm lub rotor, thiab armature nyob rau ntawm stator. Cov motors muaj zog siv electromagnets ua tus ncej. Tab sis kuj tseem muaj hom hluav taws xob qis - ib qho chaw ruaj khov hlau nplaum synchronous lub cev muaj zog. Qhov sib txawv tseem ceeb ntawm cov tshuab synchronous thiab asynchronous yog qhov tsim ntawm stator thiab rotor.
Rau overclockinglub cev muaj zog mus txog qib ntawm kev ntsuas ceev feem ntau siv hom asynchronous. Hauv hom no, inductor winding yog luv luv. Tom qab lub cev muaj zog mus txog qhov ntsuas ceev, lub rectifier pub cov inductor nrog cov tam sim no ncaj qha. Tsuas yog ntawm qhov ntsuas nrawm tuaj yeem ua lub tshuab synchronous khiav ntawm nws tus kheej.
Lub cav no muaj ntau qhov zoo. Nws yog qhov kev txiav txim ntawm qhov loj dua qhov nyuaj tshaj li lub tshuab asynchronous, tab sis qhov no yog offset los ntawm ntau qhov zoo. Ib qho txiaj ntsig tseem ceeb yog nws lub peev xwm ua haujlwm yam tsis muaj kev noj lossis rov qab los ntawm lub zog reactive. Nyob rau hauv rooj plaub no, lub hwj chim ntawm lub cav yuav sib npaug rau kev sib koom ua ke. Nyob rau hauv cov xwm txheej zoo li no, AC synchronous lub cev muaj zog yuav thauj khoom lub network tshwj xeeb nrog rau cov khoom nquag. Ib qho kev mob tshwm sim yuav yog qhov txo qis ntawm qhov ntev ntawm lub cev muaj zog (rau lub cev muaj zog asynchronous, lub stator winding yog xam rau ob qho tib si active thiab reactive tam sim no). Txawm li cas los xij, lub tshuab synchronous kuj tuaj yeem tsim lub zog reactive los ntawm kev khiav hauj lwm hauv hom overexcited.
Lub cev muaj zog synchronous tsis tshua muaj kev cuam tshuam rau kev nce siab thiab qhov hluav taws xob poob hauv lub network. Tsis tas li ntawd, cov tshuab hluav taws xob zoo li no muaj kev tiv thaiv ntau dua rau kev ua haujlwm dhau. Los ntawm kev nce cov excitation tam sim no, lub peev xwm ntawm lub cev muaj zog tuaj yeem nce ntxiv. Qhov kom zoo dua ntawm kev ua haujlwm nrog lub tshuab synchronous kuj yog qhov ntsuas nrawm nrawm rau txhua qhov kev thauj khoom (tshwj tsis yog overloads).
Undoubtedly, xws li lub tshuab xws li lub tshuab synchronous muaj nws cov ntsiab lus tsis muaj zog. Lawv cuam tshuam nrog cov nqi nce thiab kev ua haujlwm nyuaj. Qhov teeb meem tseem ceeb yog cov txheej txheem ntawm excitation ntawm lub tshuab hluav taws xob thiab nws cov kev taw qhia rau hauv synchronism. Tam sim no, thyristor exciters tau pom kev faib tawm, uas muaj kev ua haujlwm ntau dua li cov tshuab hluav taws xob exciters. Txawm li cas los xij, lawv cov nqi ntau dua. Nrog kev pab los ntawm thyristor hloov, ntau yam teeb meem tuaj yeem daws tau: kev tswj xyuas kom zoo ntawm cov khoom siv hluav taws xob zoo, tswj tus nqi tas li ntawm cosine phi, tswj cov hluav taws xob ntawm cov tsheb npav, kev tswj hwm ntawm stator thiab rotor tam sim no hauv hom xwm txheej ceev thiab thaum lub sij hawm overloads..
