Yuav ua li cas mus cuag lub cev muaj zog 380 rau 220: schema

Muaj tej yam teeb meem nyob qhov twg cov khoom nyob rau ntawm 380 volts, koj yuav tsum tau txuas mus rau ib tug lub tsev network 220 V. Txij thaum lub engine yog tsis pib, koj yuav tau hloov nws nyob rau hauv ib co nthuav dav. Qhov no yuav ua tau yooj yim los ntawm koj tus kheej. Txawm txawm lub fact tias cov efficiency rau txo me ntsis, qhov no mus kom ze yog justified.

Peb-theem thiab ib theem motors

Yuav kom to taub li cas coj mus cuag cov hluav taws xob lub cev muaj zog nrog 380 rau 220 volts, peb kawm tau dab tsi nws txhais tau hais los muaj hwj chim nyob rau ntawm lub 380 volts.

Peb-theem motors muaj ntau yam zoo piv rau tib theem tsev neeg. Yog li ntawd, lawv yog lug siv nyob rau hauv kev lag luam. Thiab nws tsis yog tsuas yog lub hwj chim, tab sis kuj nyob rau hauv efficiency. Lawv kuj muab cov pib kauj thiab capacitors. Qhov no simplifies tus tsim ntawm tus mechanism. Piv txwv li, tus txhais zov ntawm lub tub yees relay lem yuav ua li cas muaj ntau yam vrublyus winding. Ib tug peb-theem lub cev muaj zog nyob rau hauv no lub caij yuav tsum tau tsis tsim nyog.

Qhov no yog accomplished nyob rau hauv peb theem, thaum lub sij hawm uas rotates nyob rau hauv lub stator magnetic teb.

Yog vim li cas 380?

Thaum lub teb rotates nyob rau hauv lub stator, lub rotor kuj tsiv. Revolutions tsis coincide nrog tsib caug Hertz network vim lub fact tias ntau ntawm windings, tus xov tooj ntawm tug yog yav tom ntej, raws li zoo raws li rau ntau yam yog vim li cas, ris hauv qab no tshwm sim. Cov ntsuas yog siv rau lub cev muaj zog ncej ceev kev cai.

Tag nrho peb theem muaj ib tug nqi ntawm 220 V. Txawm li cas los, qhov txawv ntawm ob ntawm lawv, ntawm txhua lub sij hawm yuav sib txawv los ntawm 220. Yog li ntawd tau 380 volts. Uas yog, lub cav siv lub 220 mus ua hauj lwm, thaum muaj ib theem ua haujlwm, yog ib puas thiab nees nkaum degrees.

Vim hais tias yuav ua li cas coj mus cuag cov lub cev muaj zog 380 rau 220 volts ncaj qha yog tsis yooj yim sua, peb yuav tsum siv tricks. Lub capacitor yog xav tau qhov uas yooj yim txoj kev. Thaum lub khob kis theem, lub tom kawg yog hloov los ntawm cuaj caum degrees. Thaum kawg yog ib puas thiab nees nkaum, nws tsis tuaj, nws yog txaus yuav pib thiab khiav ib tug peb-theem lub cev muaj zog.

Yuav ua li cas mus cuag lub cev muaj zog 380 rau 220

Yuav kom siv cov kev pab raws qib koj yuav tsum to taub yuav ua li cas los txua lub windings. Feem ntau, lub cev yog kev tiv thaiv los ntawm cov vaj tse nyob thiab xov nyob hauv nws. Tom qab tshem nws, koj yuav tsum mus xyuas lub txheem. Feem ntau koj yuav nrhiav tau cov xov daim duab. Yuav kom txuas lub cev muaj zog rau lub network coj qhov chaw 380-220, switching yog siv nyob rau hauv daim ntawv ntawm cov hnub qub. Qhov xaus ntawm lub winding yog ntawm ib qho chaw, uas yog hu ua nruab nrab. Theem noj rau sab nraud.

"Star" yuav tau hloov. Ua li no, lub cev muaj zog windings yuav tsum tau kev cob cog rua nyob rau hauv ib tug txawv daim ntawv - nyob rau hauv daim ntawv ntawm ib tug peb tog, sib txuas lawv rau hauv lub xaus rau txhua lwm yam.

Yuav ua li cas mus cuag lub cev muaj zog 380 rau 220: schema

Lub tswvyim tej zaum yuav raws li nram no:

• mains voltage yog thov mus rau lub thib peb winding;
• ces ib tug thawj kauj voltage mus los ntawm ib tug condenser nrog ib theem ua haujlwm ntawm cuaj caum degrees;
• tus thib ob kauj yuav cuam tshuam rau voltage txawv.

Nws yog to taub hais tias cov theem ua haujlwm yuav tig cuaj caum thiab plaub caug-tsib degrees. Vim hais tias ntawm no niaj hnub sib hloov yuav tsis ua hauj lwm. Nyob rau hauv tas li ntawd, qhov zoo ntawm lub thib ob theem winding yuav tsis tau sinusoidal. Yog li ntawd, tom qab peb-theem lub cev muaj zog txuas nrog rau 220 volts kawm tau ntawv zoo, nws yuav tsis muab los siv tsis muaj hwj chim tsis tau. Tej zaum, txawm tus ncej nrog thiab tsis spinning.

Ua hauj lwm muaj peev xwm

Tom qab pib qhov-up ceev dialing muaj peev xwm yuav tsis yuav tsum tau, vim cov kuj zog yuav tsis tseem ceeb. Yuav kom tshem tawm nws muaj peev xwm pab kom cov kuj los ntawm kev uas tam sim no yuav kis tsis tau. Rau txoj kev xaiv ntawm kev khiav hauj lwm thiab pib-up muaj peev xwm nyob rau hauv thawj qhov chaw yuav tsum coj mus rau hauv tus account uas lub operating voltage ntawm lub capacitor yuav tsum tau tshuam tshooj 220 volts. Thaum kawg nws yuav tsum 400 V. Nws tseem yog tsim nyog them sai sai mus rau lub nyob ntawm tej uas cov currents tau tsim rau ib theem network.

Nrog heev me me ua hauj lwm txog ntsha tsob ntoo yog nplaum, yog li thawj zaug acceleration yog siv rau nws.

Ua hauj lwm muaj peev xwm kuj yog cuam tshuam los ntawm yam nram qab no:

• Qhov ntau haib lub cev muaj zog, tus loj dua cov nominal capacitor yuav tsum tau. Yog hais tias tus nqi yog 250 W, yuav suffice thiab ob peb kaum ntawm microfarads. Txawm li cas los, Yog hais tias lub hwj chim yuav siab dua, thiab lub nominal tus nqi yuav yog los ntawm cov pua pua. Capacitors zoo dua yuav zaj duab xis, vim hais tias nws yuav muaj ib tug ntxiv hwj chim kom tiav (lawv yog tsim rau cov nruam, es AC, thiab tsis muaj alterations yuav tawg).
• Qhov loj qhov cav ceev, thiab cov denomination xav tau kev pab saum toj no. Yog hais tias koj noj cov cav ntawm 3000 rpm thiab 2.2 kW, lub roj teeb yuav tsum tau 200 mus rau 250 microfarads. Thiab qhov no yog ib yam uas tseem ceeb heev.

Tsis tau no muaj peev xwm nyob rau hauv lub load.

Cov theem kawg

Nws yog lub npe hu hais tias lub electric tsav 380 rau 220 volts yuav ua hauj lwm zoo dua nyob rau hauv cov kev tshwm sim hais tias cov voltage qhov tseem ceeb yog tau nrog sib npaug. Rau no kauj yog kev cob cog rua rau ib tug network, koj yuav tsum tau tsis txhob kov, tab sis lub peev xwm yog ntsuas ntawm lub ob lwm leej lwm tus.

Nyob rau hauv lub asynchronous tsav nws muaj nws reactance. Nws yog tsim nyog yuav tau txhais qhov tsawg kawg nkaus uas nws yuav pib mus rau kiv. Tom qab hais tias, cov denomination maj nce mus raws li ntev raws li tag nrho cov windings tau equalized.

Tab sis thaum lub cev muaj zog saws mus, tej zaum nws yuav tshwm sim uas koob pheej ntawm lawv yog ua txhaum. Nws proiskhodtit rau luag yuav txo tau. Yog li ntawd, ua ntej txuas lub electric tsav 380 rau 220 volts thiab yuav txhim kho tau nws, nws yog tsim nyog los equalize lub qhov tseem ceeb ntawm lub tsev thaum lub sij hawm lub lag luam.

Lub voltage tej zaum yuav saum toj no 220 V. Saib, uas saib kuas ruaj khov pos hu, thiab muaj tsis muaj tsis muaj hwj chim los ntawm overheating. Qhov zoo tshaj plaws ntawm tag nrho cov switching yog ua li cas rau tshwj xeeb terminals taag bolts. Thaum kev cob cog rua rau lub cev muaj zog 380 rau 220 volts tshwm sim nrog cov tsim nyog tsis nyob hauv chav dua muab tso rau hauv lub casing, thiab cov nyob ntawm tej yog dhau los ntawm cov sab ntawm cov roj hmab foob.

Yuav ua li cas lwm tus muaj peev xwm tshwm sim thiab yuav ua li cas los daws kom tau cov teeb meem

Feem ntau, tom qab lub rooj sib txoos qhia hais tias tus ncej rotates nyob rau hauv lub yuam kev nyob rau hauv uas koj xav tau. koj yuav tau hloov cov kev taw qhia.

Rau no peb kauj yog kev cob cog rua ntawm ib tug capacitor mus rau lub ntsia hlau terminals ntawm lub thib ob stator winding.

Nws tshwm sim hais tias vim lub sij hawm ntev ua hauj lwm nrog lub cav suab nrov tshwm sim thaum lub sij hawm. Txawm li cas los, lub suab ntawm ib tug txawv hom raws li muab piv rau lub roar ntawm tsis yog kev twb kev txuas. Nws tshwm sim thaum lub sij hawm thiab cav co. Tej zaum twb muaj lub hwj chim tig lub rotor. Feem ntau qhov no yog tshwm sim los ntawm kev coj thiab tsim kua muag ntawm bearings, vim hais tias cov neeg uas muaj ntau ntau qhov chaw thiab cov suab nrov. Thaum lub sij hawm, qhov no yuav ua tau kom jamming, thiab tom qab ntawd - mus puas cav qhov chaw.

Nws yog zoo dua kom tsis txhob no, txwv tsis pub lub mechanism yuav ua worthless. Cias hloov cov bearings nrog sawv daws yuav tshiab. Ces tus tsav yuav kav rau xyoo yuav tuaj.
