Pulse transformer: hauv paus ntsiab lus ntawm kev txiav txim thiab tej nta

Lub transformer yog ib tug theej nyuab kev ntaus ntawv nws thawj muaj nuj nqi yog cov pom ntawm tej zog thiab cov yam ntxwv ntawm hluav taws xob xws li voltage los yog torque. Tsis tas li ntawd niaj hnub transformer muaj peev xwm hloov AC rau DC los yog vice versa.

Ntawm cov loj loj ntau yam tam sim no siv vremyapriborov notably tus mem tes ntawm lawv hom.

Cov mem tes transformer yog dav siv nyob rau hauv kev sib txuas lus tshuab, BT, automation pab kiag li lawm, ua rau tus mem tes amplitude hloov, raws li zoo raws li lawv polarity. Lub ntsiab mob rau muaj kev vam meej cov lag luam ntawm no hom ntawm ntaus ntawv yog hais tias lub distortion teeb liab uas yog kis tau nrog nws, yuav tsum tau tsis tshua.

Cov mem tes transformer yog raws li nyob rau hauv lawv cov chaw ua hauj lwm nyob rau hauv cov nram no hauv paus ntsiab lus: thaum nyob rau nws cov tswv yim tau txais lub pulses ntawm ib tug tej yam voltage nyob rau hauv cov thawj winding yog maj tawm hluav taws xob tam sim no, lub hwj chim ntawm uas maj pib nce. Qhov no, nyob rau hauv lem, yuav ua rau ib tug kev hloov nyob rau hauv lub magnetic teb thiab cov emergence ntawm ib tug electromotive quab yuam nyob rau hauv lub thib ob kauj. Nyob rau hauv cov ntaub ntawv no, lub teeb liab distortion tsis yog tshwm sim, thiab tau poob ntawm qhov tam sim no yog li ntawd me me uas yuav tsis saib xyuas.

Raws li rau qhov tsis zoo lam ua, uas yog kev tsis pom nrias nyob rau hauv cov tsos, thaum tus mem tes transformer mus rau tus tsim muaj peev xwm, nws cov nyhuv yuav tsis tshua los ntawm qhov chaw kawm ib tug yooj yim diode nyob rau hauv lub thib ob winding. Yog li, ntawm no lub zog yuav nyob ze rau lub.

Pulse transformer txawv los ntawm lwm yam ntau yam ntawm cov kev uas ua hauj lwm thiaj tau tuaj nyob rau hauv lub unsaturated hom. Nws magnetic tub ntxhais yog ua los ntawm ib tug tshwj xeeb hlau, uas tas muaj ib tug loj muaj peev xwm magnetic teb.

Nyob rau hauv tas li ntawd Pulse nyob rau hauv niaj hnub lub zog thiab electronics kev lag luam siv cov nram qab no lub ntsiab hom transformers:

1. Cov kev ua ub tej yam niaj hnub Radiopribor tsis yooj yim sua yam uas tsis muaj hwj chim transformers. Lawv kev ua ub no multifaceted: nyob rau hauv ib tes, lawv yog tsim nyog los xyuas kom meej tias lub receivers yuav noj los ntawm ib tug pa alternating tam sim no network, thiab nyob rau lwm yam, nyob rau hauv thiaj li yuav tsa los yog txo lub voltage ntawm ib tug zaus nyob rau hauv lub amps. Nrog rau qhov no muaj nuj nqi hais txog thiab tseem ceeb tsim feature ntawm lub hwj chim transformers - es tsis txhob ntawm hlau cores siv no zoo ntawm magnetite los yog carbonyl hlau.
2. Lwm hom apparatus siv feem ntau nyob rau hauv niaj hnub mus txog qhovtwg tshuab, thiab on-board computers ntawm aircraft, ib tug teb transformer. Nws paus ntsiab lus ntawm lub lag luam yog tias tus ncej sib hloov lub kaum sab xis yog hloov dua siab tshiab rau hauv hluav taws xob tam sim no voltage. Externally rotating transformer yog ib tug me me hluav taws xob tshuab, kev khiav hauj lwm heev dua lwm yam los ntawm cov AC. Nyob rau hauv tas li ntawd, nyob ntawm seb qhov twg lub transformers siv, lawv yuav tsum yog bipolar los yog multipolar.
3. Nyob ntawm seb ib tug tam sim no ntws mus rau lub thawj kauj, transformer cais DC thiab AC. Cov yooj yim saib ntawm ib tug thawj hom - autotransformer uas muaj heev dua lwm yam ntawm ib tug tib kauj, uas yog ncaj qha mus muab kev koom tes nyob rau hauv qhov hluav taws xob Circuit Court. Qhov no hom ntawm cov khoom no yog npaj thiaj tau tuaj rau undervoltage thiab tsuas yog rau cov me me currents. Transformer DC - ib tug ntau ntaus ntawv, muaj raws ntawm cav thiab dynamo. Nyob rau hauv cov ntaub ntawv no, cov thawj tam sim no generated los ntawm cov cav, thiab cov theem nrab - ib tug dynamo uas yog tsav los ntawm tib lub cev muaj zog. Feem ntau cov teeb meem no tshwm sim thaum lub DC tsav yog ib tug transformer thiab dinamomomashinu sib thooj, ib tug hlau ncej. Qhov no yog ua nyob rau hauv thiaj li yuav cawm tau cov ntaub ntawv thiab tseem rau kev txhim kho qhov zoo ntawm lub twj paj nruag.
