Txuas ib tug peb-theem lub cev muaj zog

Nyob rau hauv hluav taws xob engineering, muaj ob txoj kev yooj yim rau koj mus cuag peb-theem lub cev muaj zog. Lawv yog cov ho txawv los ntawm txhua lwm yam, thiab lawv xaiv nyob rau hauv lub khiav hauj lwm tej yam kev mob thiab engine hom.

Tus thawj hom siv ib tug peb-theem lub cev muaj zog kev twb kev txuas hu ua "daim duab peb sab." Nws yuav lub stator windings nyob rau hauv series kev twb kev txuas. Nyob rau hauv qhov tseeb, qhov kawg ntawm lub thawj pib-up lub cev muaj zog Winding kev cob cog rua rau lub thib ob. Qhov no hom ntawm kev twb kev txuas yuav tsum tau qhov tshwm sim ntawm siab starting currents thiab tso cai rau cov cav mus muab tag nrho nameplate muaj peev xwm.

Qhov thib ob hom ntawm kev twb kev txuas yog hu ua ib tug "lub hnub qub". Thaum uas siv cov nws, qhov xaus ntawm lub windings yog kev cob cog rua ua ke nyob rau ntawm lawv sab saum toj thiab energized. Xws li ib tug kev twb kev txuas ntawm peb-theem lub cev muaj zog yog ntau maj mam, tab sis lub cav ua ib tug ib nrab sij hawm tsawg hwj chim tshaj thaum txuas lub "daim duab peb sab".

Cov feem ntau tsim nyog ua ke yog xav kom ua tau ib tug kev twb kev txuas. Nws yog siv mas nyob rau hauv tus muaj hwj huam motors, tab sis nws yog tseem haum rau lub tej yam kev mob ntawm lub neej, raws li nws tiv thaiv lub cav ntawm ruaj congestion, thiab nyob rau tib lub sij hawm nws muab nws tag nrho muaj peev xwm, raws li tau teev nyob rau hauv lub passport. Nws pib lub engine los ntawm kev siv kev twb kev txuas hom "lub hnub qub". Txawm li cas los, nws yuav tsis muaj kev hnyav loads high currents. Tom qab cov kev ceev nce mus txog lub nominal tus nqi, nws yog hloov mus rau lub winding hom "daim duab peb sab", uas kav mus txog thaum kawg ntawm kev ua hauj lwm. Qhov no kev twb kev txuas yuav siv cov peb theem lub cev muaj zog lub sij hawm hloov los yog ib tug tshwj xeeb oob khab.

Nyias, yog tsim nyog sau cia hais tias feem ntau ntawm cov tshuab zoo li cas rau voltage hloov mus hloov los los yog luv luv Circuit Court. Yog li ntawd, tsim tej yaam num rau peb-theem lub cev muaj zog kev twb kev txuas, feem ntau yog nyob rau hauv cov saw hlau muaj xws li fuses los yog tag nrho kev tiv thaiv mechanisms.

Heev feem ntau, muaj coob tus neeg yuav ntsib nrog ib tug teeb meem uas lub Tshuag muaj ib tug peb-theem lub cev muaj zog, thiab lub fais network muaj xwb ib theem. Nyob rau hauv xws li mob, siv kev twb kev txuas ntawm peb-theem lub cev muaj zog nyob rau hauv tib theem network nrog rau kev siv ntawm capacitors. Lawv txuas ntawm cov dawb davhlau ya nyob twg winding thiab kev cob cog rua rau lub network. Nws yuav tsum coj mus rau hauv tus account lub fact tias cov capacitor capacitance yuav tsum txawv nyob ntawm seb muaj pes tsawg tus cav revolutions. Yog li ntawd, lawv muaj kev cob cog nyob rau hauv thaum uas tig mus rau txhua lwm yam nyob rau hauv xws li ib tug yam uas thaum ob leeg capacitors tau switched network, thiab rau kev nkag mus kawm rau hauv lub operating ceev ntawm lub thib ob capacitor yuav tsum raug kaw.

Yog li ntawd, thaum peb-theem lub cev muaj zog kev twb kev txuas yog ua rau ib leeg-theem Circuit Court, ib tug capacitor, lossi khiav, hu ua cov neeg ua hauj, tab sis ib tug uas yog muab tua, hu ua ib tug txhais. Nyob rau hauv no oob khab capacitor capacitance yuav tsum kwv yees li peb lub sij hawm loj tshaj cov ua hauj lwm. Start capacitor yog kev cob cog rua ntawm ib tug nyias muaj nyias ib khawm, uas yog nyob rau hauv lub cav tso zis ntawm lub teev ceev.

Nws yog ib nqi sau cia hais tias nrog no kev twb kev txuas lub cav loses ntau tshaj 60% ntawm nws cov peev xwm, thiab yog hais tias nws yog kev cob cog rua siv ib tug "lub hnub qub", xws li ib tug tsis yuav nce los ntawm lwm ib nrab. Yog li ntawd, nyob rau hauv xws li mob nws yog pom zoo kom siv cov tswvyim "daim duab peb sab" rau lub hwj chim losses yog nyoog.
