Nyob rau hauv lub zog ntws ntawm lub ntiaj teb kev lag luam, muaj ob hom khoom siv tseem ceeb uas ua lub luag haujlwm tseem ceeb ntawm kev ua ntsiag to: ib qho yog lub transformer, uas zoo li ib tug khov kho "voltage dispatcher", sawv ntsug thiab converting voltage npaum li cas; Lwm qhov yog lub cev muaj zog, uas, zoo li suav tsis txheeb "lub zog tso zis caj npab", tsav txhua yam ntawm cov kiv cua mus rau siab - tsheb ciav hlau ceev. Kev ua haujlwm ntawm tus ntsuj plig ntawm ob qho tib si -kev ua haujlwm siab thiab kev nyob ntsiag to- feem ntau nyob ntawm qhov zoo li zoo tib yam tab sis ua tau zoo cov khoom siv hlau: silicon steel.
1. Lub hauv paus ntsiab lus tseem ceeb: Vim li cas silicon hlau thiaj li tsim nyog?
Silicon steel yog qhov tseem ceeb hlau nrog 1% -3% silicon sib xyaw ua ke. Nws yuav zoo li ib qho yooj yim, tab sis ntxiv silicon kho ob qhov teeb meem loj nrog cov khoom siv hluav taws xob pov tseg.
(1) Hlau poob:
Thaum lub magnetic teb nyob rau hauv cov tub ntxhais hlau hloov dua thiab dhau, nws heats li vim hysteresis thiab eddy tam sim no. Lub zog khib nyiab no hu ua hlau poob. Yog tias koj ntxiv silicon, nws yeej txhim kho qhov zoo ntawm cov khoom tiv thaiv hluav taws xob, uas txo qis tam sim no thiab txo txoj kev poob ntawm lub zog.
(2) Magnetic quab yuam:
Silicon hlau tuaj yeem tau txais lub zog sib nqus zog dua li cov hlau tsis tu ncua siv tib lub teb sib nqus. Qhov no txhais tau hais tias cov khoom siv tuaj yeem ua rau tib qhov chaw sib nqus, lossis lub zog, tab sis ua kom me me thiab siv cov khoom siv tsawg, uas ua rau cov khoom me me thiab ua haujlwm zoo dua.
Yog li, silicon steel tsis yog kev xaiv xwb; nws yog txoj hauv kev zoo tshaj kom paub tseeb tias cov khoom muaj zog-txuag, tsis txhob kub dhau, tsis muaj suab nrov, thiab pheej yig.
2. Daim ntawv thov tiag tiag: Yuav ua li cas "siv" silicon steel rau transformers thiab motors
(1) Nyob rau hauv lub transformer: "hlau core" uas nrhiav kev ntsiag to thiab kev noj tsawg.
Transformers yog txhua yam hais txog kev txav zog nyob ib puag ncig, tsis siv nws. Cov hlau sab hauv tau tig rov qab los ntawm 50/60Hz lub zog, thiab qhov ntawd yog qhov feem ntau ntawm qhov poob los ntawm. Qhov kev poob no hloov ncaj qha mus rau hauv tshav kub.
- Yuav Ua Li Cas: Lawv siv cov ntawv tshwj xeeb silicon steel thiab xuas nrig ntaus rau hauv cov duab, thiab muab tso rau hauv zoo li cov blocks, ces tuav lawv ua ke nrog cov khoom xws li epoxy lossis pluaj. Cov txheej txheej no pab nres cov dej ntws txawv txawv ntawm kev ntws ncig.
- Qhov kev taw qhia txhais li cas: Txias- dov taw qhia silicon steel yog nyob rau hauv feem ntau transformers. Cov khoom yog kho kom cov nplej me me kab, ua kom yooj yim rau magnetize nyob rau hauv ib txoj kev. Thaum lawv ua lub transformer, lawv ua kom paub tseeb tias cov kev taw qhia yooj yim nrog cov magnetic teb sab hauv. Yog li, magnetizing nws yog ib qho yooj yim super, thiab muaj tsawg poob thaum nws tig rov qab thiab tawm mus. Xav txog nws zoo li txoj kev sib nqus hlau nplaum rau hluav taws xob, yog li nws tsis tas yuav tawm tsam ntau npaum li ntawd.
(2) Hauv lub cev muaj zog: "stator thiab rotor core" uas sib npaug kev ua haujlwm thiab tus nqi.
Motors yog txoj kev trickier dua transformers. Hloov chaw magnetic teb uas tsuas yog rov qab mus thiab tawm mus, motors muaj ib qho uas tig nrawm nrawm. Cov tub ntxhais hlau cuam tshuam nrog kev hloov pauv sai hauv kev sib nqus thiab qhov kev ntxhov siab ntawm kev sib hloov tas li.
- Yuav ua li cas nws tau ua: Lub cev muaj zog stators (sab nrauv, tsis yog- txav ib feem) thiab rotors (lub chaw spinning) siv tsis yog-cov ntawv qhia txog silicon steel. Cov no yog stamped rau hauv txoj cai zoo, stacked, thiab ces nias ua ke.
- Vim li cas ho tsis yog - taw qhia qhov tseem ceeb: Hauv lub cev muaj zog, cov hlau nplaum ib txwm tig thiab hloov pauv. Tsis muaj ib qho kev taw qhia yooj yim rau cov hlau nplaum. Tias yog vim li cas peb xav tau txias - dov, tsis yog -qhia silicon steel. Nws ua zoo li lub magnetic square, nrog zoo nkauj npaum li qub magnetic zog nyob rau hauv txhua txoj kev. Qhov no ua kom tsis kam qis thiab ruaj khov, tsis hais txoj kev twg nws yog magnetized.
