Lub transformer yog ib qho khoom siv hluav taws xob siv los hloov qhov loj ntawm AC voltage thiab ua lub luag haujlwm tseem ceeb hauv lub zog hluav taws xob.
Los ntawm cov qauv kev pom, lub transformer feem ntau yog tsim los ntawm cov tub ntxhais hlau thiab windings. Cov tub ntxhais hlau feem ntau yog ua los ntawm silicon steel los xij thiab yog siv los muab cov hlau nplaum sib nqus. Lub winding tau muab faib ua thawj winding thiab theem nrab winding, thiab qhov kev hloov hluav taws xob yog pom tau los ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction.
Kev faib tawm los ntawm kev siv, muaj cov khoom siv hluav taws xob, cov khoom siv hluav taws xob tshwj xeeb (xws li hluav taws xob rau hluav taws xob transformers, rectifier transformers, thiab lwm yam), cov cuab yeej siv hluav taws xob (xws li hluav taws xob transformers, tam sim no transformers), thiab lwm yam.
Nyob rau hauv cov nqe lus ntawm kev ua hauj lwm hauv paus ntsiab lus, transformers yog raws li txoj cai ntawm electromagnetic induction. Thaum AC voltage yog siv rau thawj winding, ib tug alternating magnetic flux yog generated nyob rau hauv lub hauv paus, thiab cov magnetic flux no dhau los ntawm lub thib ob winding, yog li inducing ib tug voltage nyob rau hauv lub thib ob winding. Nws qhov kev hloov pauv voltage nyob ntawm qhov hloov pauv ntawm thawj winding thiab theem nrab winding.
Cov kev ua haujlwm tsis zoo ntawm lub tshuab hloov pauv muaj xws li ntsuas qhov muaj peev xwm, ntsuas qhov ntsuas hluav taws xob, luv luv-circuit impedance, tsis muaj kev thauj khoom poob, thauj khoom poob, thiab lwm yam.
Thaum lub sijhawm ua haujlwm thiab kev saib xyuas ntawm cov transformers, yuav tsum tau them nyiaj rau kev ntsuas kub, ntsuas kev ua haujlwm ntawm rwb thaiv tsev, tiv thaiv overload thiab lwm yam teeb meem kom ntseeg tau tias lawv txoj haujlwm ruaj ntseg thiab ruaj khov.
Nyob rau hauv cov nqe lus ntawm txoj kev loj hlob ntawm transformers, lawv yog tas li tsim nyob rau hauv cov lus qhia ntawm high efficiency, lub zog txuag, txawj ntse, miniaturization thiab ib puag ncig tiv thaiv. Kev siv cov ntaub ntawv tshiab thiab cov thev naus laus zis tshiab tseem niaj hnub txhawb kev nce qib ntawm kev lag luam transformer.
