Ntiv nplhaib-Hom Iron Cores rau Hluav Taws Xob Transformers: Kev Xaiv thiab Zoo

Yog vim li cas lub nplhaib puab

Lub nplhaib- hom hlau core, tseem hu ua toroidal core, yog lub kaw sib nqus sib nqus qhov txhab los ntawm cov hlua txuas txuas ntxiv. Vim hais tias cov flux mus tag nrho hauv lub nplhaib yam tsis tau hla qhov sib txawv ntawm huab cua, qhov sib nqus tam sim no me me thiab cov hlau nplaum sib nqus yog tsawg, uas txhim kho qhov ua tau zoo thiab txo qhov cuam tshuam ntawm transformer.

Rau tib lub zog, lub nplhaib - hom transformer yog me dua thiab sib dua li qhov sib npaug EI - core unit, thiab nws khiav ntsiag to vim tsis muaj cov pob qij txha uas tuaj yeem co. Cov khoom no ua rau lub nplhaib tseem ceeb yog qhov kev xaiv rau siab - zoo transformers hauv cov khoom siv compact.

Cov khoom siv rau Ring Cores

Cov khoom siv ntau tshaj plaws yog cov nplej- taw qhia silicon steel, uas muaj qhov saturation ntawm 2.03 T thiab poob qis ntawm 50 lossis 60 Hz thaum lub flux ua raws li cov kev taw qhia dov ntawm lub strip. Qib raug xaiv los ntawm nws qhov kev lees paub qhov poob, piv txwv li 30Q120 nrog qhov siab tshaj plaws ntawm 1.20 W / kg ntawm 1.7 T thiab 50 Hz.

Rau qis tsis muaj-load poob lossis siab dua kev khiav hauj lwm zaus, amorphous alloy thiab nanocrystalline ribbon yog siv. Cov ntaub ntawv no raug nqi ntau dua tab sis txo cov tub ntxhais poob qis heev, uas yog kev ncaj ncees hauv lub zog -txuag transformers thiab hauv siab - zaus hluav taws xob hluav taws xob.

Xaiv yam

Thawj qhov kev xaiv yog qhov yuav tsum tau muaj hwj chim, uas teev cov tub ntxhais ntoo khaub lig-section thiab lub qhov rais loj. Tus ntoo khaub lig-section yuav tsum nqa cov dej ntws ua haujlwm yam tsis muaj saturation, thiab lub qhov rais yuav tsum haum rau cov winding uas yuav tsum tau muaj cov lem thiab hlau loj.

Qhov thib ob yog qhov kev tso cai poob, uas yog teem los ntawm lub hom phiaj ntawm kev ua haujlwm thiab kev ua kom txias ntawm cov khoom siv. Qhov thib peb yog qhov kev khiav hauj lwm zaus, uas txiav txim siab seb silicon steel, amorphous lossis nanocrystalline cov khoom siv, thiab qhov kawg qhov tseem ceeb yog qhov kev txwv tsis pub siv cov khoom siv ntawm lub qhov rooj, uas kho cov kab sab nraud thiab qhov siab.

Dimensions thiab Tolerances

Lub nplhaib cores yog txhais los ntawm sab nraud txoj kab uas hla, sab hauv txoj kab uas hla thiab qhov siab. Sab nraud txoj kab uas hla thiab qhov siab txiav txim siab qhov chaw nyob hauv cov khoom, thaum sab hauv txoj kab uas hla thiab qhov siab txhais lub qhov rais winding. Lub qhov rais yuav tsum loj txaus rau lub winding bobbin los yog winding tshuab shuttle.

Standard cores muaj nyob rau hauv ib tug series ntawm ntau thiab tsawg, thiab kev cai cores raug mob rau kos duab. Txoj kab uas hla yog tuav rau kev ua siab ntev ntawm qhov ntxiv los yog rho tawm 0.5 hli thiab qhov siab ntxiv los yog rho tawm 0.3 hli rau cov khoom hwm.

Kev xeem zoo

Each production batch of ring cores is tested for the core loss and the magnetizing current at the rated frequency and flux density, and the results are compared with the guaranteed values. Cov txheej txheem stacking raug txheeb xyuas los ntawm qhov hnyav ntawm cov tub ntxhais thiab sib piv cov ntim cov hlau tiag tiag nrog cov ntim geometric.

Dimensional checks npog sab nraud thiab sab hauv diameters, qhov siab, roundness thiab smoothness ntawm lub puab nto. cores uas dhau qhov kev ntsuam xyuas yog coated los yog cased thiab packed nrog ntug kev tiv thaiv kev thauj mus los.

Cov lus nug nquag

Q: Vim li cas qhov dej ntws ntawm lub nplhaib - hom tub ntxhais qis qis?
A: Lub nplhaib kaw coj tag nrho cov flux nyob rau hauv cov khoom, thiab lub winding nyob ib ncig ntawm tag nrho lub nplhaib sib npaug. Tsis muaj qhov sib txawv ntawm huab cua thiab tsis muaj txoj hauv kev, yog li cov xau inductance thiab cov hluav taws xob hluav taws xob tsawg dua li hauv cov tub ntxhais laminated EI.

Q: Cov tub ntxhais loj npaum li cas cuam tshuam nrog lub zog transformer?
A: Lub hwj chim ntawm lub transformer yog kwv yees li proportional rau cov khoom ntawm cov tub ntxhais ntoo khaub lig-section thiab winding qhov rais. Cov neeg muag khoom muab cov rooj fais fab rau cov qauv nplhaib cores, thiab rau cov qauv tsim kev cai, qhov ntsuas ntsuas yog xam los ntawm cov duab geometry, qhov flux ceev thiab qhov ceev tam sim no ntawm winding.

Q: Dab tsi yog qhov ua haujlwm flux ceev ntawm silicon steel nplhaib core?
A: Rau grain -oriented steel qhov ua haujlwm flux ceev yog feem ntau 1.5 txog 1.7 T ntawm 50 Hz. Qhov no ua kom cov hlau nplaum tam sim no thiab qhov poob qis thaum siv cov khoom zoo hauv qab nws qhov saturation ntawm 2.03 T.

Q: Puas tuaj yeem siv lub nplhaib ntawm 400 Hz?
A: Yog, tab sis qhov poob tseem ceeb nce nrawm nrog zaus. Rau kev ua haujlwm 400 Hz cov tub ntxhais yuav tsum tau derated mus rau qhov ua haujlwm qis dua, lossis cov khoom siv thinner xws li amorphous ribbon yuav tsum raug xaiv.

Q: Yuav ua li cas cov cores xa?
A: Cov cores raug xa tawm liab qab, nrog rau cov txheej txheem insulating, los yog hauv cov ntaub ntawv tiv thaiv nrog lossis tsis muaj terminals. Cov txheej txheem ntim khoom tiv thaiv cov npoo thiab tiv thaiv corrosion thaum thauj thiab khaws cia.
