Distribution Transformer Winding
Distribution transformers ua lub luag haujlwm tseem ceeb hauv kev faib hluav taws xob zoo thiab txhim khu kev qha los ntawm daim phiaj hluav taws xob rau cov neeg siv khoom. Cov transformers no yog siv los txo qis qhov hluav taws xob ntawm hluav taws xob mus rau theem uas tsim nyog rau kev siv hauv tsev, kev lag luam, thiab lwm qhov chaw. Ib qho ntawm cov khoom tseem ceeb tshaj plaws ntawm kev faib khoom transformer yog lub winding system.
Lub winding system nyob rau hauv ib tug faib transformer muaj xws li ob pawg ntawm windings - thawj winding thiab theem nrab winding. Thawj winding yog txuas nrog lub hauv paus ntawm high voltage hluav taws xob, thaum lub thib ob winding pub cov zis voltage tsawg rau lub tis network. Hauv lwm lo lus, thawj winding ua hauj lwm raws li cov tswv yim, thaum lub thib ob winding muab cov zis ntawm transformer.
Cov windings lawv tus kheej feem ntau yog ua los ntawm tooj liab los yog txhuas hlau, uas yog coiled nyob ib ncig ntawm ib tug sib nqus core ua los ntawm hlau los yog hlau. Thaum lub sijhawm ua haujlwm, qhov hloov pauv tam sim no (AC) uas ntws los ntawm cov thawj winding tsim ib qho chaw sib nqus uas induces ib qho hluav taws xob tam sim no nyob rau hauv lub thib ob winding. Tus nqi ntawm qhov voltage uas yog induced nyob rau hauv lub thib ob winding yog txiav txim los ntawm tus naj npawb ntawm lem nyob rau hauv lub thawj winding thiab tus naj npawb ntawm lem nyob rau hauv lub thib ob winding. Nyob rau hauv txoj kev no, lub transformer muaj peev xwm nqis-down voltage ntawm hluav taws xob mus rau theem yuav tsum tau.
Ib qho ntawm cov yam ntxwv uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub tshuab winding yog cov rwb thaiv tsev uas siv los cais cov windings ntawm ib leeg thiab los ntawm cov tub ntxhais. Cov khoom siv rwb thaiv tsev yuav tsum muaj peev xwm tiv taus hluav taws xob thiab thermal kev ntxhov siab uas tshwm sim thaum lub sijhawm ua haujlwm. Cov ntaub ntawv rwb thaiv tsev muaj xws li ntawv, roj, thiab cov khoom siv hluavtaws xws li epoxy resin. Cov txheej txheem rwb thaiv tsev yuav tsum tau tsim los txo qis zog poob thiab kom ntseeg tau tias muaj cua sov dissipation uas yog tsim los ntawm transformer.
Lwm qhov kev txiav txim siab tseem ceeb rau lub tshuab winding yog lub winding configuration. Feem ntau hom winding configurations yog ib-theem thiab peb-theem winding tshuab. Kev xaiv ntawm hom winding configuration nyob ntawm daim ntawv thov thiab qhov yuav tsum tau muaj qhov voltage.
Hauv kev xaus, lub winding system yog ib qho tseem ceeb ntawm kev faib khoom transformer. Kev tsim qauv tsim nyog thiab kev tsim kho ntawm lub tshuab winding tuaj yeem ua kom muaj txiaj ntsig thiab txhim khu kev lag luam ntawm lub tshuab hloov pauv thiab txhawb nqa kev xa hluav taws xob rau cov neeg siv khoom. Kev xaiv cov khoom tsim nyog, winding configuration, thiab rwb thaiv tsev tsim yog tag nrho cov kev txiav txim siab tseem ceeb los xyuas kom meej qhov kev ua tau zoo ntawm transformer winding system.
