50 lossis 60Hz transformers feem ntau sivsilicon steel laminations, feem ntau txiav los yog xuas nrig ntaus los ntawm 0.5mm los yog hauv qab, uas yog varnished los yog coated ntawm ob sab. Qhov no ua rau qhov xav tau eddy tam sim no tsuj lossis tshem tawm.
Muaj ob hom tseem ceeb ntawm ib-theem transformers, raws li qhia hauv daim duab 1.
Daim duab 1: 50 / 60Hz Fais fab Transformer Hom
Plhaub Hom Transformers:Rau me me transformers, lubhom plhaubraug xaiv. Cov kev hloov pauv tau tshwm sim muaj ib qho spool nqa ob qho tib si thawj thiab theem nrab windings, raws li pom hauv daim duab 1(a). Cov laminations tuaj yeem muab tso rau ntau qhov siab sib txawv, nyob ntawm qhov ntsuas VA xav tau. Cov pawg siab no raug xaiv kom haum rau ib qho ntawm ntau tus tswv winding spools. Cov laminations siv yog stamped los ntawm daim ntawv thiab raug xa mus rau "E & I" laminations vim lawv cov duab. Cov no tau qhia ntau yam ntxiv hauv daim duab 2(a).
Limb Hom Transformers:E & I laminations dhau los ua kev lag luam tsawg dua li qhov kev ntsuas VA nce ntxiv. Qhov chaw raug cua sov muaj rau cov cua txias ua feem tsawg dua rau qhov loj dua, yog li yuav tsum tau loj dua, ntau dua, thiab kim dua cores kom tau txais VA ntsuas. Yog li ntawd, rau qhov loj transformerslimb homraug xaiv, raws li qhia hauv daim duab 1(b). Cov txiaj ntsig transformers muaj ob lub voj voog, nrog rau txhua tus nqa ob qho tib si thawj thiab theem nrab windings, cov windings yog sib txuas hauv cov koob thiab / lossis sib npaug raws li qhov xav tau. Cov laminations yog cov duab plaub yooj yim txiav los ntawm daim ntawv thiab muab tso rau hauv daim duab 2(b).
Daim duab 2: Cov duab thiab stacking ntawm silicon steel laminations
Qhov kev ntsuas ntsuas saum toj no uas txiav cov cores dhau los ua kev lag luam ntau dua li E & I cores, ob qho tib si hauv cov nqi thiab tsis muaj peev xwm, yog nyob nruab nrab ntawm 2kVA thiab 3 kVA.
Tom ntej: Toroidal TransformersCov laminations saum toj no yog randomly xuas nrig ntaus thiab txiav los ntawm ib daim ntawv ntawm silicon steel, yog li cov nplej orientation tsis tuaj yeem ua tau. Muaj lwm txoj hauv kev uas cov khoom siv lamination yog tsim nyob rau hauv ib lub strips, thiab cov hmoov nplej hlau yog oriented nyob rau hauv cov kev taw qhia ntawm lub sawb. Qhov no nplej-orientated sawb yog ces raug mob rau hauv lub toroid zoo li yob ntawm daim ntawv tso quav tso. Lub resulting toroidal transformer muaj tag nrho cov hlau nplej nyob rau hauv cov hlau khiav circumferentially ces tej zaum yuav ua hauj lwm ntawm ib tug ntau dua flux ceev. Qhov no ua rau lub teeb dua, me dua, thiab muaj txiaj ntsig zoo dua. Txawm li cas los xij, cov khoom siv kim dua, thiab cov kws tshwj xeeb coiling thiab shuttle winding machinery yuav tsum tau tsim. piv txwv ntawm toroidal transformers koj yuav paub txog yog tam sim no transformers thiab "variac transformers" (Daim duab 3).
Daim duab 3: Toroidal Core Piv txwv
400Hz Cores:Rau cov transformers siv nyob rau hauv 400Hz (xws li aerospace kev lag luam), hysteresis poob ntawm silicon steel ntau rau 50 los yog 60 Hz daim ntaub ntawv tej zaum yuav ua unmanageable, yog li cov ntaub ntawv nrog ib tug ntau linear excitation (BH) nkhaus thiab qis hysteresis yuav tsum tau.Amorphous steel cores (hlau iav)muaj cov cuab yeej txhim kho thiab tsim nyog rau cov ntawv thov no. Ntawm 50 / 60 Hz cov no muaj ib feem peb qhov kev poob ntawm cov pa silicon steel tab sis yog ob zaug kim.
High-Frequency Cores:Ntawm cov zaus siab (1kHz thiab siab dua), cov ntaub ntawv saum toj no tsis haum vim tias lawv qhov kev poob siab hysteresis. Yog li, cov khoom siv ferrite feem ntau yog xaiv. Ferrites yog cov khoom siv hluav taws xob ntawm cov hlau hloov pauv nrog cov pa oxygen, uas yog ferrimagnetic tab sis nonconductive. Ferrites uas siv rau hauv transformer los yog electromagnetic cores muaj hlau oxides ua ke nrog npib tsib xee, zinc, thiab / los yog manganese tebchaw. Lawv muaj cov coercivity tsawg uas muaj txiaj ntsig zoo rau kev ua haujlwm siab.
Daim duab 4: Piv txwv ntawm Ferrite Cores
Ferrite cores tuaj yeem muab pov rau hauv ib qho kev xav tau, raws li qhia hauv daim duab saum toj no.
