Kuv nkag siab koj qhov kev txhawj xeeb. Los ntawm kev pom kev tshaj lij, kev txiav txim siab qhov zoo ntawm transformer tester cov khoom siv hinges ntawm kev sib piv ntawm cov khoom siv nominal specifications nrog kev ua tau zoo thiab cov qauv kev lag luam. Qhov txias txias -cov ntaub ntawv silicon steel, amorphous alloys, copper windings, thiab stainless hlau casing koj tau hais yog plaub qhov tseem ceeb rau kev ntsuas qhov zoo ntawm nws cov khoom tseem ceeb.
Cov khoom siv tseem ceeb: Txias- Rolled Silicon Steel Sheets vs. Amorphous Alloys Cov tub ntxhais yog "lub plawv sib nqus" ntawm tus ntsuas, thiab nws cov khoom cuam tshuam ncaj qha rau kev ntsuas qhov tseeb thiab ruaj khov.
Txias-rolled Silicon Steel Sheets: Tus qauv rau kev ua tau zoo yog kev siv siab -permeability, qis- hlau- poob taw qhia txias- dov silicon steel los xij (xws li 30Q130 thiab 35Q140). Kev txheeb xyuas tuaj yeem ua tau raws li hauv qab no:
Xyuas seb cov khoom siv cov ntaub ntawv qhia txog qib silicon steel ntawv qib thiab cov nqi hlau poob (P1.7/50 Tsawg dua lossis sib npaug rau 1.3W / kg yog nyiam).
Siv B-H nkhaus tester los ntsuas lub hysteresis voj thiab txiav txim siab seb qhov permeability thiab saturation sib nqus induction siv tau raws li cov qauv.
Hauv kev ua haujlwm tiag tiag, qhov tsis muaj -load tam sim no yuav tsum ruaj khov, tsis muaj qhov kub thiab txias siab lossis suab nrov txawv txav.
Amorphous Alloy:
Yog hais tias lub amorphous alloy core tau thov kom siv, cov qauv tsim nyog suav nrog:
Cov tub ntxhais muaj ib lub qhov txhab (tsis laminated), nrog ib tug strip thickness ntawm kwv yees li 0.03 hli.
Qhov tsis muaj -load poob yuav tsum yog tsawg kawg yog 70% qis dua li ntawm silicon steel ntawv tseem ceeb ntawm tib lub peev xwm.
Nco ntsoov nws rhiab heev rau mechanical stress; zam kev cuam tshuam thiab deformation thaum thauj thiab teeb tsa.
Winding Material: Copper windings yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm siab.
Cov khoom siv winding txiav txim siab conductivity thiab kub nce tswj.
Copper winding cov qauv tsim nyog:
Resistivity yuav tsum tsawg dua los yog sib npaug rau 1.724 × 10⁻⁸ Ω·m (20 degree), txheeb xyuas los ntawm DC tsis kam kuaj.
Tsis yog-kev ntsuas kev puas tsuaj yuav tsum tau ua los ntawm kev siv cov khoom siv hluav taws xob hloov pauv (piv txwv li, ZX-BC188), nrog rau qhov kev pab cuam txiav txim siab thiab tso tawm qhov "tooj liab" tus cwj pwm.
Cov cuab yeej siv siab- kawg yuav tsum siv cov pa oxygen- cov hlau tsis muaj tooj liab nrog tus du, oxidation -dawb nto thiab cov pob qij txha muaj zog.
Ceev faj ntawm "aluminium es tsis txhob tooj liab": Lub resistivity ntawm aluminium windings yog kwv yees li 1.6 npaug ntawm tooj liab, yooj yim ua rau kev ntsuas tsis raug thiab overheating. Ntawm - kev txheeb xyuas qhov chaw tuaj yeem ua tau los ntawm kev siv cov txheej txheem thermoelectric los yog qhov kub coefficient ntawm kev ua haujlwm.
