Transformers - nws yog ib qho tseem ceeb heev ib feem ntawm lub electronics

Transformers - cov no yog cov pab kiag li lawm uas ua si ib qho tseem ceeb heev luag hauj lwm nyob rau hauv cov cheeb tsam uas siv hluav taws xob lub zog. Lawv lub ntsiab lub hom phiaj yog lub cim ntawm hluav taws xob thiab nws mov. Nyob rau hauv cov kev tshwm sim hais tias tus tam sim no hloov mus rau lwm yog ib tug ntev deb, nws yuav tsum tau me me, thaum lub sij hawm voltage - siab. Qhov no yuav txo tau cov nqi. Nyob rau lwm cov tes, txiav txim siab txhawj xeeb yuav tsum tau loj nyiaj ntawm insulating cov ntaub ntawv, uas ua rau yus cov nqi siab dua. Transformers - yog li uas yog siv nyob rau hauv thiaj li yuav pab txhawb xws li ib tug contradiction. Nyob rau hauv ib nutshell, lawv yog siv faiv fab thawj ua rau kom cov voltage, thiab ces - mus txo nws. Vim rau qhov no, tus neeg tau txais qhov zoo tshaj plaws rau lawv tus kheej tam sim no.

Nyob rau hauv Feem ntau, lawv siv peb-theem transformers. Qhov no yuav ua tau piav los ntawm lub fact tias cov hluav taws xob mov muaj peb theem. Tsawg zaus teem ob peb zaug xwb units, kev cob cog rua ntawm ib lub hnub qub los yog daim duab peb sab. Efficiency nyob rau hauv transformers tam sim no siv nce mus txog 99 feem pua. Dua li no feem tseem ceeb ntawm lub hwj chim yog kev poob lawm vim tshav kub. Uas yog vim li cas lawv siv ib tug qhia tshwj xeeb uas tsim txias system.

Tsav network hom transformer (uas yog feem ntau nyob rau hauv lub neej txhua hnub) yog ua raws li lub hauv paus ntsiab hais tias ib tug ntau yam ntawm lub tsev hluav taws xob khoom siv ntawm qhov ntau thiab voltage. Tej lub sij hawm dhau los, cov ntsiab teeb meem ntawm cov pab kiag li lawm yog ib tug loj nyhav thiab qhov ntev. Yuav kom daws tau nws yog tam sim no rectified voltage, uas yog ces hloov dua siab tshiab rau hauv pulses ntawm ib tug siab zaus. Ntxiv mus, nyob rau hauv lub transformer, lawv yuav muab cov kev tsim nyog tsis. Cov tshuaj no tso cai rau kom txo tau cov zuag qhia tag nrho fais fab mov tsis. Muaj kuj yog lam ua ntaus ntawv. Lub hauv paus ntsiab lus ntawm cov transformer ntawm no hom yog txo mus rau lub fact tias nws yog nqa tawm lub thiaj li hu ua kis tau tus mob lub mem tes. Lub hom phiaj tseem ceeb ntawm xws li ib tug ntaus ntawv yog kis pulses tsis muaj distortion.

Cov yooj yim tshaj plaws yog siv xws li raws li autotransformers. Thawj thiab theem nrab windings yog ncaj qha mus txuas nrog rau ib leeg. Vim hais tias ntawm no nruab nrab ntawm lawv nws kuj yuav tau thiab hluav taws xob kev twb kev txuas, tsis tsuas electromagnetic. Lub winding muaj tsawg kawg yog peb outputs. By txuas mus rau txhua yam ntawm lawv yog tsim nrog txawv voltage qhov tseem ceeb. Xws li yog yus muaj los ntawm high efficiency, vim hais tias hloov dua siab tshiab yuav siv sij hawm qhov chaw uas tsuas muaj ib feem ntawm lub hwj chim. Nrog rau qhov no Circuit Court xws transformers tsis muaj rwb thaiv tsev ntawm lawv, ua rau lawv pheej yig dua. Nyob rau hauv no hais txog, feem ntau lawv yog siv rau industrial hom phiaj.

Nyob rau hauv xaus, nws yuav tsum tau muab sau tseg tias transformers - yog li ntawd kuj muaj ib tug kev sib cais muaj nuj nqi. Nyob rau hauv lwm yam lus, lawv ua hauj lwm hauv kev txiav txim kom tsis txhob muaj txoj kev pheej hmoo ntawm tib neeg poob siab thaum kov ib tug grounded caij thiab tsis zoo insulated ntaus ntawv. Qhov tseeb hais tias nyob rau hauv lub mob switching los ntawm lub ntaus ntawv nws yuav tsis yooj yim sua kom koj hu rau theem nrab Circuit Court nrog "av" thiab hluav taws xob poob siab.
