DC high-voltage fais fab mov tuaj yeem siv raws li lub zog siv hluav taws xob ntawm lub tshuab hluav taws xob
DC switching fais fab mov yog AC fais fab mov uas nquag siv hauv kev tsim khoom, thiab feem ntau ntawm DC hauv Suav teb thoob ntiaj teb yog 50 hertz. Lub zog ua haujlwm ntawm DC hloov hluav taws xob siv rau induction cua sov siv rau cov khoom siv induction yuav tsum tau kho. Raws li qhov tso zis hluav taws xob loj ntawm cov cuab yeej siv cua sov thiab qhov ntim loj ntawm lub zog hluav taws xob network, DC high-voltage fais fab mov (6-10KV) tuaj yeem siv los muab lub zog rau lub tshuab hloov pauv; Cov cuab yeej siv tshuab cua sov tuaj yeem txuas tau tam sim ntawd rau 380V hauv qab hluav taws xob hluav taws xob hluav taws xob.
Qhov nruab nrab zaus fais fab mov siv high-frequency diesel generators rau lub sij hawm ntev. Nws muaj lub tshuab hluav taws xob ntau zaus thiab tus tsav tsheb asynchronous. Lub hwj chim ntawm hom tshuab hluav taws xob no feem ntau nyob hauv thaj tsam ntawm 50-1000KW. Nrog rau txoj kev loj hlob ntawm lub zog hluav taws xob tshuab hluav taws xob, qhov nruab nrab zaus fais fab mov ntawm bidirectional thyristor soft starter tau siv. Hom kev siv hluav taws xob nruab nrab no siv cov thyristors bidirectional los ua ntej hloov DC AC lub zog rau DC lub zog, thiab tom qab ntawd hloov DC lub zog rau hauv AC lub zog ntawm qhov xav tau zaus. Vim lawv qhov me me, lub teeb yuag, tsis muaj suab nrov, thiab kev lag luam txhim khu kev qha, hom DC zaus hloov tshuab tau maj mam hloov cov tshuab hluav taws xob ntau zaus.
Cov khoom siv hluav taws xob siab hluav taws xob feem ntau yog thawj zaug siv lub tshuab hluav taws xob kom nce qhov ua haujlwm ntawm peb theem 380 volts mus rau qhov hluav taws xob siab txog li 20000 volts. Tom qab ntawd, siv thyristors lossis high-voltage silicon rectifier Cheebtsam rau rectifier DC AC lub zog rau hauv DC lub zog, thiab tom qab ntawd siv cov khoom siv hluav taws xob los ua kom lub zog DC rau hauv high-frequency, high-voltage AC zog. Lub zog ntawm high-voltage fais fab mov tshuab thiab cov cuab yeej siv txij li kaum ntawm kilowatts mus rau ntau pua kilowatts. Cov nyhuv thermoelectric generated los ntawm induced tam sim no (vortex) tshwm sim los ntawm alternating magnetic teb ntawm ib tug hluav taws xob conductor ua rau tus neeg xyuas pib kom sov nws tus kheej. Raws li cov txheej txheem cua sov sib txawv, qhov zaus ntawm AC fais fab mov siv rau induction cua sov muaj xws li DC (50-60 Hz), high-frequency (60-10000 Hz), thiab high-frequency (siab dua 10000 Hz) .
