Dab tsi yog Fais Fab Transformer
Lub hwj chim transformer yog ib qho khoom siv hluav taws xob uas siv los hloov cov hluav taws xob siab, tsis tshua muaj hluav taws xob tam sim no mus rau qhov tsis tshua muaj hluav taws xob, hluav taws xob tam sim no lossis lwm yam. Nws yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob hauv hluav taws xob uas pab tswj cov hluav taws xob thiab cov theem tam sim no kom xa hluav taws xob zoo thiab muaj kev nyab xeeb nyob rau qhov ntev.
Lub hwj chim transformer muaj ob los yog ntau dua coils ntawm hlau qhov txhab nyob ib ncig ntawm ib tug ferromagnetic core. Thawj kauj yog txuas nrog lub zog hluav taws xob siab, thaum lub coil thib ob txuas nrog lub nra. Thaum lub zog hluav taws xob siab tau siv rau hauv lub hauv paus kauj, nws tsim ib qho chaw sib nqus hauv cov tub ntxhais, uas ua rau cov hluav taws xob tam sim no nyob rau hauv lub kauj thib ob. Cov txheej txheem ntawm kev hloov hluav taws xob hluav taws xob los ntawm ib theem voltage mus rau lwm qhov yog hu ua electromagnetic induction.
Fais fab transformers yog siv nyob rau hauv ntau yam kev siv, xws li kis tau tus mob thiab kev faib ntawm hluav taws xob fais fab mus rau industrial thiab coj mus muag siv. Lawv feem ntau categorized los ntawm lawv lub zog muaj peev xwm, uas muaj peev xwm nyob ntawm ob peb kilovolt-amperes (kVA) mus rau ntau pua megavolt-amperes (MVA).
Ib qho tseem ceeb tshaj plaws ntawm kev siv hluav taws xob transformers yog nyob rau hauv kev sib kis thiab kev faib hluav taws xob hluav taws xob nyob rau hauv qhov ntev. Yuav kom txo tau lub zog poob, cov qib hluav taws xob tau nce mus rau qib siab heev (feem ntau 765 kV lossis 1,100 kV) rau kev sib kis mus ntev. Lub zog hluav taws xob siab yog tom qab ntawd nqis los siv cov hluav taws xob hloov hluav taws xob ntawm cov theem sib txawv mus rau qib qis dua qhov tsim nyog rau kev siv los ntawm cov neeg siv khoom.
Lwm daim ntawv thov ntawm lub zog hloov hluav taws xob yog nyob rau hauv cov txheej txheem kev lag luam, uas lawv tau siv los ua kom nce lossis nqis qis qis kom tau raws li cov kev cai tshwj xeeb ntawm cov khoom siv. Piv txwv li, nyob rau hauv ib tug steel cog, lub hwj chim transformers yog siv los muab high voltage hwj chim rau cov furnaces, thaum nyob rau hauv ib tug tshuaj cog, lawv yog siv los muab hluav taws xob tsis tshua muaj hluav taws xob rau cov tswj systems.
Ntxiv rau qhov hloov pauv hluav taws xob, lub zog hloov hluav taws xob kuj tuaj yeem siv rau kev sib cais, qhov chaw uas lawv siv los cais cov thawj thiab theem nrab circuits. Qhov no tuaj yeem muaj txiaj ntsig zoo nyob rau hauv cov xwm txheej uas yuav tsum tau muaj qhov sib txawv voltage, lossis qhov twg cov suab nrov hluav taws xob yuav tsum raug tshem tawm.
Hauv cov ntsiab lus, lub zog hloov hluav taws xob yog ib qho tseem ceeb hauv cov khoom siv hluav taws xob hluav taws xob, thiab ua lub luag haujlwm tseem ceeb hauv kev tswj qhov hluav taws xob thiab qib tam sim no txhawm rau xa hluav taws xob zoo thiab nyab xeeb nyob rau qhov ntev. Lawv yog siv nyob rau hauv ntau yam kev siv, los ntawm kev sib kis thiab kev faib hluav taws xob hluav taws xob mus rau cov txheej txheem kev lag luam, thiab raug cais los ntawm lawv lub peev xwm.
