Cov txheej txheem los txo qhov tsis muaj load poob ntawm hluav taws xob substation transformer

Los ntawm kev txheeb xyuas ntawm tsis muaj kev poob, qhov poob hysteresis thiab eddy tam sim no poob ntawm cov hlau tseem ceeb yog txiav txim siab los ntawm cov chaw tsim khoom silicon steel, thiab qhov poob ntxiv yog txiav txim siab los ntawm cov chaw tsim khoom hluav taws xob substation transformer. Qhov sib nqus flux ntom ntom ntawm cov tub ntxhais hlau yog qhov tseem ceeb uas cuam tshuam rau qhov tsis muaj qhov poob ntawm cov tub ntxhais transformer. Yog li ntawd, txhawm rau txo qhov tsis muaj-thau tau flucetle fluity faib nyob rau hauv txhua feem ntawm cov cim hlau hauv qab tias cov hlau ua haujlwm tseem tsis hloov. , txo qis hauv zos sib nqus flux ceev ntawm cov ces kaum ntawm cov tub ntxhais.

1. Staggered seams raug hloov mus rau qhov thib peb-txiav seams

Txij li thaum muaj qhov sib txawv nyob rau hauv cov pob qij txha ntawm lub transformer hlau core silicon steel nplooj ntawv, cov hlau nplaum kuj dheev nce thaum cov hlau nplaum flux dhau los ntawm cov pob qij txha. Qhov nce hauv cov hlau nplaum tiv thaiv thoob plaws hauv inter-chips kuj ua rau lub zos sib nqus sib nqus ntawm cov laminations uas nyob ib sab, uas ua rau muaj kev nce hauv qhov tsis muaj qhov poob thiab muaj peev xwm excitation.

Qhov ntau lub seam series ntawm cov hluav taws xob substation transformer core, qhov qis hauv zos poob hauv cheeb tsam seam, tab sis qhov me dua qhov txo qis hauv zos poob. Lub crafting nyuaj ntawm daim ntawv yuav nce raws li seam kev loj hlob.

Hauv kev xyaum, xav tias nrog kev nce ntawm cov theem, lub sij hawm txiav ntawm silicon steel ntawv thiab stacking ntawm cov tub ntxhais hlau nce raws li, thiab cov txheej txheem lamination ua phem dua. Xav tias yog siv peb-theem seam, xaiv ib hom ntawv haum, thiab tsuas yog ib hom ntawv ntxiv rau hauv kem tseem ceeb, cov txheej txheem nyuaj yog me ntsis ntxiv, thiab cov khoom sib nqus tau zoo tuaj. Peb-theem seam ntawm cov tub ntxhais hlau yog tsim los ntawm alternating stacking ntawm peb hom laminations. Raws li cov txheej txheem thev naus laus zis ntawm kev kho hluav taws xob metallurgical kev lag luam thiab cov ntaub ntawv sib nqus kev ua haujlwm ntawm kev sib koom tes, kev siv peb-theem kev sib koom ua ke yog qhov kev xaiv zoo tshaj plaws rau kev txhim kho cov staggered sib koom tes hlau core.

Kev siv S9-800/10 thiab S{2}}/10 fais fab transformers ua piv txwv, tib hom transformer txais tib lub tswv yim tsim, qauv thiab cov khoom siv, thiab cov tub ntxhais hlau txais cov txheej txheem sib txawv. Class seam, 1000kVA 2 units txais staggered seam, 3 units txais tertiary seam.

Los ntawm cov ntaub ntawv ntsuam xyuas, nws tuaj yeem txiav txim siab tias qhov tsis muaj kev thauj khoom ntawm peb-theem sib koom ua ke yog txo los ntawm 7 feem pua ​​​​mus rau 8 feem pua ​​​​ntawm qhov nruab nrab piv nrog cov staggered sib koom thaum hla ntu ntawm kab tseem ceeb tseem tsis hloov. Lub tertiary seam tsuas yog ib hom ntawv ntxiv rau hauv cov tub ntxhais kem, thiab shearing ntawm silicon steel ntawv thiab lub sij hawm stacking ntawm cov tub ntxhais hlau yog me ntsis ntxiv, tab sis cov txiaj ntsig tau zoo kawg li.

2. Txo qhov dav ntawm lub puab tsaig ntawm cov tub ntxhais hlau thiab txo qhov tsis muaj qhov poob ntawm cov tub ntxhais hlau

Nyob rau ntawm cov ces kaum ntawm cov tub ntxhais laminations, lub puab tsaig dav ntawm qhov sib koom ua ke ntawm cov tub ntxhais ceg thiab tus quab yuam transverse muaj qee yam cuam tshuam rau qhov tsis muaj kev ua haujlwm ntawm lub transformer. Qhov loj dua qhov sib tshooj, qhov loj dua qhov chaw uas cov hlau nplaum sib nqus hla, uas ua rau muaj kev nce hauv qhov tsis muaj kev thauj khoom. Raws li cov qauv hlau core test, qhov tsis muaj load poob ntawm 45 degree sib koom ua ke yuav nce los ntawm 0.3 feem pua ​​​​rau txhua 1 feem pua ​​​​nce hauv cheeb tsam sib tshooj. Txhawm rau txo qhov tsis muaj kev thauj khoom, nws yog ib qho tsim nyog los kawm txog kev xaiv qhov zoo tshaj plaws ntawm lub puab tsaig rau ob qho tib si tsis muaj kev thauj khoom thiab lub zog ntawm lub tshuab ua haujlwm raws li qhov kev txaus siab ntawm lub zog txhua yam.

Hloov qhov chaw sib txuas ntauwd ntawm cov tub ntxhais hlau pawg, txo qhov luaj li cas ntawm qee qhov peb sab hauv cov tub ntxhais hlau, thiab txo qis hauv zos sib nqus flux ntom ntom ntawm cov duab peb sab tuaj yeem txo qhov tsis muaj qhov poob ntawm cov hluav taws xob substation transformer. Peb lub tuam txhab faib transformer Ameslikas muaj lub lamination lub kaum sab xis ntawm 10 hli, tab sis tam sim no nws tau raug hloov mus rau 5 hli, uas tau ua tiav ib qho txiaj ntsig ntawm kev txo qis. Lub lamination lub kaum sab xis ntawm cov tub ntxhais hlau yog hloov los ntawm 10mm mus rau 5mm, yog li ntawd qhov chaw hla ntu ntawm cov kab noj hniav ntawm lub kaum sab xis ntawm cov tub ntxhais hlau nce, thiab lub zos sib nqus flux ntom ntom ntawm cov kab noj hniav ntawm daim duab peb sab yuav inevitably txo.

3. Tsim nyog xaiv qhov dav ntawm cov tub ntxhais hlau, txo lub kaum qhov hnyav ntawm cov tub ntxhais hlau, txo cov khoom siv hlau, thiab txo qhov tsis muaj load.

Qhov tsis muaj load poob ntawm cov tub ntxhais hlau yog cuam tshuam nrog chav tsev hlau poob ntawm cov tub ntxhais hlau thiab qhov hnyav ntawm cov tub ntxhais hlau, thiab qhov hnyav ntawm cov tub ntxhais hlau yog ib feem ntawm qhov hnyav ntawm cov tub ntxhais hlau, yog li lub angular hnyav. qhov hnyav ntawm cov tub ntxhais hlau tsis tsuas yog cuam tshuam rau tus nqi ntawm lub transformer, tab sis kuj ncaj qha cuam tshuam rau lub transformer. tsis-load poob.
