Qhov zaus ntawm AC fais fab mov siv rau induction cua sov muaj xws li fais fab zaus

Cov nyhuv thermal tsim los ntawm qhov induced tam sim no (eddy tam sim no) generated los ntawm tus neeg xyuas pib nyob rau hauv ib qho alternating electromagnetic teb ua rau tus neeg xyuas pib nws tus kheej ua kom sov. Raws li cov txheej txheem cua sov sib txawv, qhov zaus ntawm AC fais fab mov siv rau induction cua sov muaj xws li fais fab zaus (50-60 Hz), nruab nrab zaus (60-10000 Hz), thiab siab zaus (siab tshaj 10000 Hz). Lub hwj chim zaus fais fab mov yog qhov nquag siv AC fais fab mov hauv kev lag luam, thiab lub zog zaus hauv ntau lub teb chaws thoob ntiaj teb yog 50 hertz. Qhov hluav taws xob siv rau cov cuab yeej induction los ntawm lub zog siv rau induction cua sov yuav tsum tau kho. Raws li lub zog ntawm cov khoom siv cua sov thiab lub peev xwm ntawm cov khoom siv hluav taws xob, lub zog hluav taws xob siab (6-10 kV) tuaj yeem siv los muab lub zog los ntawm kev hloov pauv; Cov khoom siv cua sov kuj tseem tuaj yeem txuas ncaj qha mus rau 380V hluav taws xob qis hluav taws xob. Qhov nruab nrab zaus fais fab mov siv nruab nrab zaus lub tshuab hluav taws xob teeb tsa rau lub sijhawm ntev. Nws muaj lub tshuab hluav taws xob nruab nrab zaus thiab lub tshuab tsav asynchronous. Lub zog tso zis ntawm hom chav tsev no feem ntau yog li ntawm 50 txog 1000 kilowatts. Nrog rau kev tsim hluav taws xob hluav taws xob thev naus laus zis, qhov nruab nrab zaus fais fab mov ntawm thyristor zaus converters tau siv. Qhov nruab nrab zaus fais fab mov no siv thyristors los ua ntej hloov AC lub zog rau hauv DC lub zog, thiab tom qab ntawd hloov DC lub zog rau hauv AC lub zog ntawm qhov xav tau zaus. Vim nws qhov me me, lub teeb yuag, tsis muaj suab nrov, thiab kev ua haujlwm txhim khu kev qha, cov khoom siv hloov pauv zaus no tau maj mam hloov cov khoom siv hluav taws xob nruab nrab. Cov khoom siv hluav taws xob ntau zaus feem ntau yog thawj zaug siv lub tshuab hloov hluav taws xob los tsa peb-theem hluav taws xob ntawm 380 volts mus rau qhov hluav taws xob siab txog li 20000 volts, tom qab ntawd siv cov thyristors lossis high-voltage silicon rectifier ntsiab los kho lub zog AC rau hauv DC lub zog, thiab tom qab ntawd siv hluav taws xob oscillators hloov DC fais fab rau hauv high-frequency, high-voltage AC zog. Cov zis hluav taws xob ntawm cov khoom siv hluav taws xob ntau zaus ntawm kaum ntawm kilowatts mus rau ntau pua kilowatts. Cov khoom rhuab los ntawm induction yuav tsum yog tus neeg xyuas pib. Thaum cov high-frequency AC tam sim no dhau los ntawm tus neeg xyuas pib, tus neeg xyuas pib tsim cov nyhuv ntawm daim tawv nqaij, uas yog, qhov ntom ntom ntawm tus neeg xyuas pib yog siab, thiab qhov nruab nrab tam sim no ntom ntawm tus neeg xyuas pib tsawg. Induction cua sov tuaj yeem ua kom sov cov khoom raws li tag nrho thiab ua kom sov rau saum npoo; Hlau uas tuaj yeem yaj tau; Nyob rau hauv lub high-frequency range, hloov cov duab ntawm lub cua sov kauj (tseem hu ua inductor) kuj tso cai rau arbitrary lub zos cua sov.
