Premium Nplhaib Transformer Iron Core

Lub nplhaib transformer hlau tub ntxhais yog lub hauv paus sib nqus Circuit Court tivthaiv ntawm lub toroidal transformer. Nws yog tsim los ntawm silicon steel sawb mus rau hauv ib lub nplhaib kaw, los ntawm kev nruam winding los yog laminating zoo li ntu, kom cov hlau nplaum flux ua raws tus du, qhov sib txawv -dawb txoj kev nyob ib ncig ntawm lub hauv paus. Qhov kaw geometry no yog dab tsi muab lub nplhaib -core transformers lawv cov tub ntxhais uas tsis tshua muaj kev poob qis, kev khiav hauj lwm tsis muaj suab nrov thiab qhov chaw tsis muaj zog, thiab nws yog vim li cas lawv tau teev tseg qhov twg qhov ua tau zoo thiab kev ua haujlwm ntsiag to yog qhov tseem ceeb.

Vim li cas lub Nplhaib Zoo Txhim Kho Magnetic Performance

Piv nrog rau cov qauv txheej txheem sib sau ua ke los ntawm E thiab kuv xuas nrig ntaus, lub nplhaib tseem ceeb muaj ob qhov kev txiav txim siab zoo:

Tsis muaj qhov sib txawv ntawm huab cua: qhov sib nqus hluav taws xob tsis tu ncua, yog li kev tsis txaus siab thiab cov hlau nplaum tam sim no raug txo kom tsawg, thiab cov tub ntxhais -poob feem cuam tshuam nrog kev sib koom ua ke ploj mus.

Kev siv tag nrho ntawm cov khoom siv: tag nrho cov ncig yog nqa cov flux ntawm tib qhov ntom, yog li tus ntoo khaub lig- ntu yog siv sib npaug thiab cov tub ntxhais yog compact rau nws qhov kev ntaus nqi.

Tsis tas li ntawd, lub nplhaib puab muaj cov hlau nplaum hauv lub hauv paus, txo cov kev cuam tshuam nrog ib puag ncig circuits, thiab nws cov symmetrical, nruj nruj qauv vibrates tsawg, yog li lub suab nrov tsawg.

Kev tsim khoom

Txoj kev winding

Nyob rau hauv lub qhov txhab txheej txheem, ib tug nruam sawb ntawm grain- taw qhia silicon steel yog qhov txhab mus rau ib tug mandrel mus rau lub sab hauv txoj kab uas hla, ces annealed los kho cov magnetic zog thiab txo winding kev nyuaj siab. Tom qab annealing cov tub ntxhais yog coated los yog encapsulated. Lub nplhaib qhov txhab tsis muaj pob qij txha ntawm txhua qhov thiab yog li qhov ua tau zoo tshaj plaws ntawm kev sib nqus; nws yog siv qhov uas yuav tsum tau muaj zog efficiency siab tshaj, xws li siab - efficiency faib transformers thiab cov khoom siv suab.

Txheej txheem lamination

Hauv cov txheej txheem lamination, cov nplooj ntawv silicon steel raug txiav mus rau hauv cov duab (ntxuam-zoo li) ntu ​​thiab muab tso rau hauv lub nplhaib. Txoj kev no ua kom yooj yim dua hauv kev tsim ntau qhov sib txawv thiab hla - ntu, thiab nws yooj yim dua los ua cov cores loj li no, tab sis cov ntu qhia ob peb lub pob qij txha, yog li kev ua haujlwm sib nqus me ntsis hauv qab ntawm lub qhov txhab ntawm lub qhov txhab. Laminated rings yog ib qho kev xaiv zoo rau lub nplhaib loj -core transformers thiab geometries tshwj xeeb.

Khoom siv thiab poob yam ntxwv

Lub nplhaib cores feem ntau yog ua los ntawm cov nplej- taw qhia silicon steel nrog cov tub ntxhais tshwj xeeb poob qis. Txoj kev taw qhia ntawm lub sawb yog ua raws li txoj kev flux nyob ib ncig ntawm lub nplhaib, thiab nyias - ntsuas cov khoom (txog 0.20–0.30 mm) txwv tsis pub dhau - tam sim no poob. Kev sib xyaw ua ke ntawm cov khoom siv taw qhia, nyias laminations thiab kev sib koom ua ke - txoj kev pub dawb tso cai rau lub tshuab hloov pauv kom tau raws li qhov xav tau tshaj plaws ntawm lub zog- kev txwv tsis pub siv nrog txo hysteresis thiab eddy - tam sim no poob. Kev ntsuas poob ua raws IEC 60404 thiab cov qauv khoom siv.

Tej kev siv

High -cov transformers ua tau zoo, ua tau raws li qhov yuav tsum tau ua ntawm kab sib chaws rau kev poob qis thiab kev siv hluav taws xob siab.

High - zaus transformers rau cov khoom siv sib txuas lus thiab tshiab - zog inverters.

Transformers rau cov cuab yeej precision xws li cov cuab yeej kho mob thiab cov cuab yeej kuaj, qhov twg tsis muaj suab nrov thiab cov khoom siv ruaj khov yog qhov tseem ceeb.

Kev rho tawm cov hloov pauv thiab cov khoom siv hluav taws xob nrog cov khoom siv hluav taws xob nruj - cuam tshuam kev txwv.

Standard Core Dimensions

Qhov ntau thiab tsawg yog tsim los kom haum rau cov kev ntsuas hluav taws xob tshwj xeeb thiab cov qhov rais winding. GNEE Hluav taws xob muab lub nplhaib cores nyob rau hauv no ntau yam nrog tswj annealing thiab txheej zoo.

FAQ

Dab tsi yog qhov txawv ntawm lub nplhaib nplhaib thiab lub nplhaib laminated?

Lub qhov txhab lub nplhaib yog tsim los ntawm ib qho txuas txuas ntxiv, yog li nws tsis muaj pob qij txha thiab qhov poob qis tshaj plaws. Lub nplhaib laminated yog sib sau ua ke los ntawm cov ntu zoo li qub, uas tso cai rau kev hloov pauv ntau dua thiab cov cores loj dua, tab sis cov pob qij txha ntxiv me me ntawm qhov poob thiab magnetizing tam sim no.

Vim li cas lub nplhaib cores ntsiag to dua li cov cores stacked?

The closed, symmetric ring structure and the tight encapsulation of the layers damp magnetostrictive vibration, and there are no loose joints to rattle, so audible noise is much lower than with E-I stacked cores.

Cov khoom siv twg yog siv rau lub nplhaib transformer cores?

Grain-taw qhia txog silicon steel sawb yog cov khoom siv rau lub zog- zaus lub nplhaib cores vim nws cov kev taw qhia dov yog ua raws li txoj hauv kev flux, muab qhov poob qis tshaj plaws. Nanocrystalline thiab amorphous ribbons yog siv rau siab - daim ntawv thov zaus.

Kuv yuav ua li cas xaiv lub nplhaib core loj?

Xaiv ib qho tseem ceeb uas nws muaj txiaj ntsig zoo - cheeb tsam Ae txhawb kev tsim cov flux ntawm qhov ntsuas hluav taws xob thiab zaus yam tsis muaj qhov saturation, thiab nws txoj kab uas hla sab hauv muab lub qhov rais txaus rau lub winding lem. Txoj kev sib nqus ntev Ie ces txiav txim siab qhov sib nqus inductance.

Lub nplhaib cores puas tuaj yeem daws DC overcurrent?

Cov lus teev cov chav kawm ntau tshaj DC overcurrent rau txhua qhov loj, qhia qhov ncaj qha tam sim no cov tub ntxhais tuaj yeem txhawb nqa ua ntej saturating lossis overheating hauv cov ntawv thov lim. Qhov tseeb txwv yog nyob ntawm tus naj npawb ntawm cov lem thiab cov kev khiav hauj lwm flux.
