Lub hwj chim transformer puas muaj hluav taws xob rau tib neeg lub cev?
Txawm hais tias lub hwj chim transformer muaj hluav taws xob rau tib neeg lub cev, peb yuav tsum xub qhia ib lub tswv yim rau cov pej xeem: nyob rau hauv lub tshav pob ntawm electromagnetic ib puag ncig thiab kev noj qab haus huv rau pej xeem, lub hwj chim kis tau tus mob thiab transformation chaw xws li transformers tsim "hluav taws xob teb", "magnetic teb". " thiab "electromagnetic field", tsis yog "electric field". Electromagnetic hluav taws xob "" Electromagnetic hluav taws xob " yog ib tug tshwj xeeb engineering lo lus nyob rau hauv lub teb ntawm xov tooj cua kev sib txuas lus engineering thiab electromagnetic compatibility. Nws tsis tsim nyog xa mus rau "electromagnetic radiation" raws li qhov cuam tshuam ib puag ncig hauv thaj chaw ntawm electromagnetic teb ib puag ncig kev noj qab haus huv. tshaj li "electromagnetic nthwv dej" rau lub zog kis tau tus mob, nyob ib ncig ntawm lub hwj chim kis tau tus mob thiab transformation chaw, muaj "hluav taws xob teb", "magnetic teb" thiab "electromagnetic teb".
Vim li cas nws thiaj hais tias lub zog xa hluav taws xob thiab cov chaw hloov pauv xws li transformers tsis tuaj yeem tsim hluav taws xob hluav taws xob zoo rau ib puag ncig? Qhov no yog vim hais tias lub zog zaus magnetic teb generated los ntawm AC fais fab kis tau tus mob thiab transformation chaw yog ib tug tsis tshua muaj magnetic teb, uas cuam tshuam rau ib puag ncig ib puag ncig los ntawm electromagnetic induction. Qhov zaus ntawm lub zog hluav taws xob zaus hluav taws xob thiab lub zog hluav taws xob zaus sib nqus tsuas yog 50Hz, thiab lub wavelength yog mus txog 6000km, thiab cov kab sib kis nws tus kheej, vim nws qhov ntev feem ntau me dua qhov wavelength no, tsis tuaj yeem tsim hluav taws xob hluav taws xob zoo. Nyob rau tib lub sij hawm, lub zog zaus magnetic teb thiab lub zog zaus hluav taws xob teb yog ywj siab ntawm ib leeg, uas yog txawv los ntawm high zaus electromagnetic teb. Cov hluav taws xob thiab cov hlau nplaum ntawm cov khoom siv hluav taws xob ntau zaus yog hloov pauv hluav taws xob uas nthuav tawm rau pem hauv ntej kom tsim hluav taws xob hluav taws xob. Nyob rau hauv cov ntaub ntawv ntawm thoob ntiaj teb cov koom haum tso cai, hluav taws xob thiab sib nqus teb generated los ntawm AC fais fab kis thiab transformation chaw yog kom meej meej hu ua lub hwj chim-frequency electric teb thiab lub hwj chim-frequency magnetic teb, es tsis yog electromagnetic tawg.
