Asynchronous lub cev - tsim thiab cov txheej txheem haujlwm

Lub induction lub cev muaj zog yog ib qho hluav taws xob lub cev muaj zog uas sau rau alternating tam sim no. Asynchronous lub tshuab fais fab no yog lub npe vim hais tias qhov sib txuam ntawm qhov qoj ntawm lub cav qog tsis sib npaug li qhov sib txawv ntawm qhov sib txawv ntawm qhov chaw tig, uas yog tsim los ntawm qhov khiav ntawm kev hloov tam sim no raws qhov cua ntawm qee qhov ntawm lub cav - lub stator. Asynchronous lub cev - feem ntau ntawm tag nrho cov hluav taws xob hluav taws xob, nws tau txais qhov chaw ntsiag to hauv tag nrho cov lag luam, engineering thiab li ntawd.

Lub tshuab xaim hauv qhov nws tsim muaj ob qho tseem ceeb tshaj plaws: lub rotor thiab tus stator. Cov khoom no yog sib cais los ntawm cov pa me me. Feem ntau ntawm lub cav kuj tseem hu ua windings thiab sib nqus Circuit Court. Cov yam ntxwv ua muaj cua txias, rotor rotation, lub zog thiab rigidity.

Lub stator yog ib txoj kev cam khwb cia los yog cov hlau cam khwb cia hlau ntawm ib hom cylindrical. Hauv tsev stator muaj vaj tse muaj hlau nplaum, lub stator winding yog muab tso rau hauv cov phiaj xwm tshwj xeeb tawm. Ob hnub xaus ntawm qhov sib tw yog txuas nrog lub npov dav hlau thiab txuas nrog ob tog lossis ib lub hnub qub. Los ntawm cov hnub xaus, lub tsev nyob sab nraud tau them tag nrho los ntawm kev tuav pov hwm. Bearings ntawm lub rotor ncej yog nias rau hauv cov bearings no. Lub rotor ntawm lub asynchronous tsav yog ib tug hlau ncej, uas qhov sib nqus Circuit Court tseem pressed.

Ua tau zoo, lub rotors yuav muab faib ua ob pawg neeg loj. Lub cav nws tus kheej yuav nqa nws lub npe raws li lub hauv paus ntsiab lus ntawm qhov rotor tsim. Ib qho qag ntawm qhov muag nrog ib tus cage-cage rotor yog thawj hom. Muaj ib qho thib ob. Qhov no yog ib lub cav asynchronous nrog ib theem rotor. Nyob rau hauv lub grooves ntawm lub cev nrog lub luv luv-rotor (nws tseem hu ua ib tug "squirrel tawb" vim zoo sib xws ntawm cov tsos ntawm xws li ib tug rotor nrog ib tug cell nyob rau hauv ib qho protein), aluminium rods yog poured nyob rau hauv thiab kaw lawv nyob rau ntawm lub xaus. Lub sij hawm rotor muaj peb lub windings nyob rau hauv nws, uas txuas nrog txhua lwm yam nyob rau hauv ib lub hnub qub. Qhov xaus ntawm cov cua ntsaws yog txuas nrog cov nplaim tsau rau ntawm lub taub hau. Thaum pib lub cav, tshwj xeeb qhov chaw txhuam nrawm nrawm rau nias ntawm cov rings. Cov txhuam yog kev cob cog rua kuj tsim los txo cov inrush tam sim no thiab ntseeg nkaws pib lub induction lub cev muaj zog. Nyob rau hauv tag nrho cov xwm txheej peb-theem nram qab no yog siv rau stator winding.

Lub hauv paus ntsiab lus ntawm kev lag luam ntawm txhua lub cav asynchronous yog yooj yim. Nws yog raws li nyob rau hauv lub npe nrov txoj cai ntawm electromagnetic induction. Lub magnetic teb ntawm lub stator generated los ntawm cov peb theem voltage system, yog rotated los ntawm cov tam sim no ntws los ntawm cov stator winding. Qhov sib nqus ntawm qhov sib tw no hla tus cua thiab cov neeg sib tw ntawm qhov rotor winding. Ntawm qhov no, ib qho kev siv hluav taws xob (EMF) yog tsim nyob rau hauv cov cua ntawm lub rotor raws li txoj cai ntawm electromagnetic induction. Qhov no EMF ua rau lub sij hawm hloov tam sim no ntws nyob rau hauv rotor winding. Qhov no rotor tam sim no tsim lub magnetic teb nws tus kheej, uas tau sib txuas nrog lub magnetic field ntawm tus stator. Txoj kev no tseem pib qhov kev sib hloov ntawm lub rotor nyob rau hauv cov hlau nplaum.

Feem ntau, los txo inrush tam sim no (thiab nws yog nyob rau hauv ib tug induction lub cev muaj zog yuav ua tau ntau lub sij hawm lub kev khiav hauj lwm tam sim no) thov pib capacitors kev cob cog rua nyob rau hauv series nrog lub pib kauj. Tom qab pib, lub capacitor no dhau los, ua rau kev kawm tsis pauv.
