Sib Nqus amplifier - kev khiav hauj lwm hauv paus ntsiab lus thiab daim ntawv thov

Sib Nqus amplifier - qhov no yog ib tug zoo li qub fais apparatus, uas yog tsim los tswj tus nqi ntawm cov magnitude ntawm alternating tam sim no ntawm ib qho chaw. Cov kev khiav hauj lwm hauv paus ntsiab lus ntawm no ntaus ntawv yog raws li nyob rau hauv uas tsis yog-linear cov yam ntxwv ntawm cov magnetized magnetic Circuit Court. Ib tug sib nqus amplifier yog feem ntau siv rau hauv lub teb uas tsis siv neeg tswj ntawm lub electric tsav (ob synchronous thiab asynchronous) uas khiav lag luam rau alternating tam sim no.

Ib tug ntaus ntawm no ntaus ntawv yog heev yooj yim. Sib Nqus amplifier muaj cov kev khiav hauj lwm winding, uas yog nyob rau ntawm nws huab rods. Nws yog ua los ntawm ob tug series-kev cob cog rua coils. Control winding nrog ib tug loj tus naj npawb ntawm lem nyob rau hauv nruab nrab pas nrig. Yog hais tias nws tsis muaj tam sim no yog nkag, thiab kis tau los ntawm tus ua hauj lwm winding, uas yog kev cob cog rua nyob rau hauv series nrog lub load, sib nqus Circuit Court yuav tsis tau noo cia cia AC voltage vim lub me me muaj pes tsawg tus lem. Nyob rau hauv cov ntaub ntawv no, tag nrho cov voltage yuav poob rau cov kuj khiav hauj lwm kauj (nyob rau hauv cov ntaub ntawv no nws yuav tsum reactive). Nyob rau hauv cov ntaub ntawv no, lub load yuav muab sau ua ke rau cov uas tsis muaj hwj chim.

Lub magnetic ntaus ntawv xws li lub sib nqus amplifier yog nyeem vim hais tias tam sim no kis tau los ntawm cov tswj winding. Vim hais tias ntawm cov loj tus naj npawb ntawm lem rau nws yog txaus txawm tias ib tug me me tam sim no. Raws li ib tug tshwm sim ntawm txoj kev no lub reactive tivthaiv ntawm cov ua hauj lwm winding kuj yuav txo dramatically thiab tam sim no tus nqi nyob rau hauv cov kev tswj Circuit Court yuav sai nce. Yog li, siv tus me teeb liab mus rau cov kev tswj winding yuav tswj tau ntau lub hwj chim.

Nyob rau hauv lub nyuaj cov ntaub ntawv xws li ib tug ntaus ntawv raws li lub magnetic amplifier nruab nrab yog cov inductance uas yog ua nrog lawv tam sim no. Rau cov tswj inductance yuav tsum tau kev cob cog rua nyob rau hauv series mus rau lub AC load Circuit Court.

Rau loj qhov tseem ceeb ntawm inductor tam sim no nyob rau hauv lub series Circuit Court thiab ib tug me me load. Thaum uas tsis muaj inductance tam sim no yuav tsum tau loj nyob rau hauv ib tug daisy saw. Nyob rau nraum chaw thau khoom, ntsig txog, tus nqi yuav tau nce nyob rau kev faib ua feem rau cov txo nyob rau hauv inductance. Muaj ntau tsim nyob rau hauv uas xws li ib tug ntaus ntawv, raws li ib tug sib nqus hwj chim yog siv raws li, piv txwv li, uas tsis yog-hu relay (rau contactless switching tam sim no) rau doubling lub zaus nqi, mus rau stabilize qhov voltage nyob rau hauv lub Circuit Court rau modulating lub siab zaus pib ntsais koj teeb lub tsawg zaus Pib ntsais koj teeb, xws li ib tug ntaus ntawv raws li ib tug tam sim no amplifier rau kev tswj cov voltage thiab thiaj li nyob.

Txawm tias nyob rau hauv tsis ntev los no xyoo, magnetic amplifiers twb nyob rau hauv ib co chaw raug thawb rov qab nws siv cov semiconductor pab kiag li lawm, nyob rau hauv tej thaj chaw xws li kev tswj ntawm hluav taws xob drives nyob rau hauv kev tsim kho machinery, lub teeb kev cai ntawm kev hais kwv txhiaj halls thiab cinemas, nyob rau hauv cov kev tswj ntawm locomotives magnetic amplifier twb tsis muaj cov neeg sib tw rau hnub no.
