Fais fab transformers tau dav siv nyob rau hauv ntau yam kev sib txuas tseem ceeb ntawm lub zog hluav taws xob, ua cov khoom siv tseem ceeb rau "voltage boosting{0}}transmission-voltage step-down" txheej txheem ntawm hluav taws xob hluav taws xob. Daim ntawv thov feem ntau yog nyob rau hauv qhov voltage boosting theem ntawm fais fab nroj tsuag. Cov zis hluav taws xob los ntawm cov tshuab hluav taws xob feem ntau yog qis, thiab lub ntsiab transformer feem ntau tsa nws mus rau 110kV, 220kV, los yog ntau dua ua ntej xa mus rau hauv lub network kis tau tus mob, txo qhov poob thaum lub sij hawm ntev - kis tau tus mob.
Nyob rau hauv cheeb tsam substations thiab hub substations, lub ntsiab transformer plays lub luag hauj lwm tseem ceeb nyob rau hauv voltage theem hloov dua siab tshiab thiab hluav taws xob faib. Hwj chim los ntawm siab-voltage kis tau tus mob yog nqis los ntawm lub ntsiab transformer thiab muab faib mus rau nruab nrab-voltage tis networks nyob rau hauv ntau qhov chaw, ntxiv muab kev lag luam, kev lag luam, thiab cov neeg siv nyob rau hauv. Cov theem no txiav txim siab qhov ruaj khov thiab muaj peev xwm ntawm ib cheeb tsam lub zog; Yog li ntawd, ntau lub ntsiab transformers feem ntau yog teeb tsa thiab ua haujlwm ua ke los txhim kho kev ntseeg tau.
Cov transformers tseem ceeb tseem ua lub luag haujlwm tseem ceeb hauv cov neeg siv khoom loj thiab cov khoom siv hluav taws xob tshwj xeeb, xws li steel mills, chemical nroj tsuag, thiab cov ntaub ntawv chaw. Cov neeg siv no muaj cov khoom siv hluav taws xob loj thiab cov kev xav tau txuas ntxiv, feem ntau xav tau kev tsim kho ntawm lawv tus kheej substations kom nqis siab - hluav taws xob hluav taws xob mus rau theem tsim nyog rau lawv cov khoom siv. Lub caij no, nyob rau hauv daim phiaj kev sib txuas ntawm cov khoom siv hluav taws xob tshiab (xws li cua fais fab thiab cov chaw siv hluav taws xob photovoltaic), lub ntsiab transformer tseem siv los txhawb qhov hluav taws xob nyob rau sab tiam thiab txuas mus rau daim phiaj kom ua tiav kev sib kis ruaj khov thiab kev sib txuas ntawm kab sib chaws.
