Nyob rau hauv tus txheej txheem ntawm transformer winding, vim muaj ntau yam yog vim li cas, nws yog ib qho yooj yim ua rau lub winding poob ntawm txheej.
Yog li, dab tsi yuav transformer winding poob txheej ua rau? Nws puas yuav tawg? Rau qhov tshwm sim no, peb tuaj yeem zam nws li cas?
Hauv tsab xov xwm "Kev paub txog kev nyab xeeb ntawm transformer", peb paub qhov tseem ceeb ntawm kev nkag mus deb thiab hluav taws xob nyob deb. Txhawm rau kom ua tau raws li qhov yuav tsum tau ua nyob deb, peb ntxiv cov kab xev thiab cov rwb thaiv tsev nyob rau hauv lub transformer; rau ntawm thawj thiab theem nrab, peb kuj siv cov phab ntsa tuav thiab peb-txheej insulated hlau kom tau raws li qhov yuav tsum tau ua.
Thaum lub transformer tau poob cov khaubncaws sab nraud povtseg, ces cov creepage thiab hluav taws xob deb ntawm cov windings yuav tsis tau raws li. Transformer windings tej zaum yuav loj heev vim yog qhov sib txawv ntawm qhov sib txawv ntawm cov windings, thiab qhov sib thooj ntawm cov laj thawj, yooj yim ua rau kev tawg ntawm luv luv Circuit Court, kom lub transformer tso zis txawv txav, tsis tuaj yeem ua haujlwm zoo, lossis txawm tias ncaj qha ua rau cov khoom siv hluav taws xob. transformer hlawv tawm.
Txawm hais tias lub transformer tsis tshwm sim txawv txav rau lub sijhawm luv luv, nws tseem yuav muaj kev cuam tshuam rau lub neej ntawm transformer. Undoubtedly, lub siab sib txawv yog loj heev, nyob ze rau lub winding, lub sij hawm ntev ua hauj lwm yuav ua rau kom lub hnub nyoog ntawm cov transformer rwb thaiv tsev cov ntaub ntawv, yog li cuam tshuam lub neej ntawm tag nrho cov transformer.
Yog li, nyob rau hauv tus txheej txheem ntawm transformer tsim thiab winding, yuav ua li cas kom tsis txhob poob txheej?
Ua ntej ntawm tag nrho cov, rau lub internal winding ntawm lub transformer, yuav tsum tau sim ua tag nrho cov txheej txheem.Ntau tus qauv tsim transformer, feem ntau los ntawm lub zog engineers theoretical xam, tsis muaj qhov tseeb winding, cov qauv ntawm nws cov kev sim ntau lawm yog feem ntau xa mus rau lub transformer Hoobkas yog lub luag hauj lwm rau.
Vim yog qhov sib txawv ntawm kev xam qhov theoretical thiab qhov tseeb winding, nws yog ib qho yooj yim uas tshwm sim tag nrho cov txheej kab tsis txaus siab. Nyob rau lub sijhawm no, vim hais tias hauv qab ntawm lub winding tsis tiaj tus, tag nrho cov txheej kab tsis txaus siab rau qhov xwm txheej, lub nraub qaum winding yuav yooj yim poob tawm ntawm txheej.
Yog li ntawd, nyob rau hauv lub transformer tsim, rau lub internal winding tsim, sim xav txog tag nrho cov txheej txheem. Rau tiag tiag tsis tuaj yeem ua tau raws li qhov xwm txheej, tab sis kuj nyob ze rau tag nrho cov txheej txheem tsim. Ntawm chav kawm, tag nrho cov txheej txheem ntawm kev tsim yuav tsum tau tswj kom tsim nyog cov npoo, tsis dhau xoob los yog nruj heev, kom ntseeg tau tias cov tshuab sib txawv winding tawm ntawm pob ntawv, yog ib txheej tiav lossis ntau txheej.
Secondly, nyob rau hauv cov ntaub ntawv ntawm ib co ntawm cov windings tsis muaj ib tug loj tus naj npawb ntawm lem, txawm winding kuj yog ib qho yooj yim mus ua rau poob txheej.Qhov teeb meem no tshwm sim tsis tau tsuas yog nyob rau hauv cov nyob sib ze nyob rau hauv lub windings yog tsis teem nyob rau hauv cov ntaub ntawv ntawm tag nrho cov txheej, tab sis kuj muaj nyob rau hauv lub nyob sib ze lub internal winding hlau txoj kab uas hla yog thicker, feem ntau ntug ntawm lub voj voog thiab lub cev pob txha muaj feem ntau ib tug loj sib txawv ntawm. cas.
Thaum lub sij hawm no, yog hais tias tus tsim yuav tsum tau txawm winding, lub ntug ntawm ib lub voj voog thiab lub cev pob txha yuav tsum tau tawm ib tug tej yam kev ncua deb ntawm, nyob rau hauv thiaj li yuav tiv thaiv kom txhob tag nrho cov winding ntawm rooj plaub, nyob rau hauv lub tshuab nyob rau hauv qhov kev txiav txim ntawm nro, sab nraud. winding ntawm feem ntau ntawm ntug ntawm 1 ~ 2 tig ncaj qha mus rau sab hauv winding ntawm ntug ntawm qhov sib txawv, ua rau lub caij nplooj zeeg ntawm txheej.
Tsis tas li ntawd, winding daim kab xev pob bias, daim kab xev yog nqaim heev, kuj yooj yim ua rau qhov tshwm sim ntawm qhov tshwm sim ntawm ntog txheej. Yog li ntawd, cov txheej txheem ntawm transformer winding yog ib qho tseem ceeb tshwj xeeb.
Nws yog tsim nyog hais tias: nyob rau hauv cov txheej txheem ntau lawm, transformer winding winding, feem ntau tsis siv neeg los yog semi-automatic tshuab, ceev ceev, winding txheej dropout yog tsis yooj yim mus kuaj. Yog li ntawd, nws yog feem ntau nyuaj rau kev saib xyuas transformer winding dropout.
Ntxiv nrog rau kev ua kom ntseeg tau qhov tsim nyog ntawm kev tsim, cov txheej txheem winding ntawm cov kab pob, xyuam xim rau lub disassembly ntawm lub pob, saib xyuas qhov sib xws ntawm lub pob, xyuas seb qhov tshwm sim ntawm cov txheej txheem poob.
