Tsis zoo li tooj liab poob, hlau poob ntawm lubtransformertsis muaj dab tsi cuam tshuam nrog cov yam xws li winding thiab tam sim no loj, raws li lub npe qhia, cov hlau tsis muaj feem xyuam rau cov hlau, uas yog tsim los ntawm cov tub ntxhais hlau. Cov hlau poob ntawm lub transformer tseem hu ua "tsis muaj-load poob", vim hais tias nws muaj nyob rau hauv tag nrho cov load thiab xoom load lub xeev ntawm lub transformer, thiab yog ib tug ruaj poob ntawm lub transformer. Txawm li cas los xij, hauv kev thauj khoom, lub zog poob yuav txo qis nrog qhov txo qis ntawm lub zog hluav taws xob.
Cov hlau poob ntawm transformer tuaj yeem muab faib ua hysteresis poob thiab eddy tam sim no poob.
Hysteresis Loss
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub transformer yog raws li lub hauv paus ntsiab lus ntawm electromagnetic induction kom ua tiav qhov nce thiab poob voltage thiab tam sim no hloov, thiab cov hlau nplaum flux nyob rau hauv lub transformer yog ntws ntawm cov tub ntxhais hlau, cov tub ntxhais hlau muaj qhov sib nqus tsis kam mus rau qhov sib nqus flux. , ib yam li tus neeg xyuas pib muaj qhov tsis kam mus rau qhov tam sim no, nws tseem yuav tsim kom muaj cua sov, xws li kev poob yog hu ua "hysteresis poob".
Eddy Tam Sim No Loss
Thaum lub hauv paus winding ntawm lub transformer yog energized, lub magnetic flux generated los ntawm lub kauj ntws nyob rau hauv cov tub ntxhais, vim hais tias cov tub ntxhais nws tus kheej kuj yog ib tug conductor, nyob rau hauv lub dav hlau perpendicular mus rau lub magnetic quab yuam kab yuav induction muaj peev xwm, qhov no muaj peev xwm tsim ib tug kaw voj. nyob rau ntawm tus ntoo khaub lig ntawm cov tub ntxhais thiab generates tam sim no, zoo li ib tug vortex, yog li nws yog hu ua "vortex". Qhov poob los ntawm qhov eddy tam sim no hu ua "eddy tam sim no poob". Nws kuj yog vim hais tias cov tub ntxhais hlau tsim cov eddy tam sim no uas nws tau ua rau hauv ib daim nyias nyias, vim hais tias lub thinner qhov tsis kam, qhov qis dua tam sim no.
Influencing Factor
1.Kev khiav hauj lwm voltage thiab zaus: Hlau poob yog cuam tshuam nrog kev khiav hauj lwm voltage thiab zaus ntawm lub transformer, vim hais tias cov yam ntxwv no cuam tshuam rau lub magnetic teb lub zog thiab hysteresis nyob rau hauv lub hlau core.
2. Cov khoom siv tseem ceeb: Cov khoom hysteresis ntawm cov khoom tseem ceeb yuav cuam tshuam qhov loj ntawm cov hlau poob. Yog tias cov khoom tseem ceeb tsis raug xaiv zoo, hysteresis poob yuav nce.
3.Cov txheej txheem tsim khoom: Cov txheej txheem tsim khoom ntawm transformer kuj muaj qee yam cuam tshuam rau cov hlau tsis zoo. Piv txwv li, txoj kev lamination ntawm cov tub ntxhais hlau, kev kho rwb thaiv tsev, thiab lwm yam, yuav cuam tshuam qhov loj ntawm cov hlau tsis zoo.
Hom qauv
1. hlau poob (unit: kVA)=I² × (Rm + Ra), Kuv yog qhov ntsuas tam sim no ntawm transformer, Rm yog hysteresis poob ntawm cov tub ntxhais hlau, thiab Ra yog qhov tsis kam ntawm cov tub ntxhais hlau.
2. hlau poob (unit: kVA)=Kf × (Bm) ^ 2 × f, Kf yog qhov tas li, Bm yog qhov flux ceev, thiab f yog qhov hloov pauv zaus.
Txoj kev txo qis
1. Xaiv cov ntaub ntawv zoo tshaj plaws: Xaiv cov ntaub ntawv tseem ceeb nrog me me hysteresis poob, uas tuaj yeem txo cov hlau poob ntawm lub transformer.
2.Txhim kho cov txheej txheem tsim khoom: txo cov hlau poob los ntawm kev txhim kho cov txheej txheem lamination ntawm cov tub ntxhais hlau, kev kho rwb thaiv tsev thiab lwm yam kev tsim khoom.
3.Tsim nyog tsim: Nyob rau hauv lub transformer tsim theem, los ntawm optimizing cov qauv tsim thiab parameter xaiv, txo cov hlau tsis.
