Classification thiab transformer ntaus ntawv

Transformer hu ua ib tug electromagnetic tshuab tsim los nce los yog yuav txo tau voltage. transformer ntaus ntawv yog invented nyob rau hauv lub lig thib kaum cuaj xyoo pua Lavxias teb sab engineer Yablochnikov lub npe. Uas yog ntev dhau los.

transformer ntaus ntawv yog heev yooj yim. Nyob rau hauv nws nyuaj daim ntawv - qhov no yog qhov tseem ceeb ntawm daim hlau hluav taws xob steel rau uas yog qhov txhab ob coils. Tus thawj kauj, hu ua cov thawj, yog kev cob cog rua rau ib lub hwj chim qhov twg los. Qhov thib ob winding, lub qhov txuas rau cov neeg siv - mus thauj khoom.

Thaum dua ib tug tam sim no ntawm cov thawj Winding kev cob cog rua rau ntawm qhov chaw, qhov no tam sim no ua ib qho kev alternating magnetic tub ntxhais khiav uas yuav ntxias nyob rau hauv lub thib ob winding EMF (electromotive quab yuam). Rau tag nrho transformers siv lub tswvyim ntawm tus transformation ratio. Nws yog cov yam ntxwv ntawm cov kev sib raug zoo ntawm voltage rau cov thawj winding mus rau lub voltage rau ob winding. Tsis tas li ntawd xam cov transformation piv yuav ua tau txheeb ze xov tooj ntawm koj lem rau lub windings. W1 / W2 = k, qhov twg W1- tooj lem ntawm cov thawj winding, W2 - feem, tus xov tooj ntawm ob lem.

Hais txog kev kho ntawm lub transformer, nws yuav tsum tau muab sau tseg tias cov hluav taws xob lub tsheb raug muab faib ua nyiaj thiab tej. Yog hais tias lub voltage ntawm ob winding yog ntau tshaj ntawm cov thawj, hu li ntawd kauj ruam-up transformer. Thiab yog hais tias lub qhov voltage yuav tsawg tshaj li tus thawj - tus yuav txo tau. Tus tam sim no nyob rau hauv lub windings yog yeej ib txwm rov qab sib raug zoo nrog cov voltage, thiab li tus naj npawb ntawm cov lem. Yog li ntawd, cov thawj kauj yog ua los ntawm cov hlau me me seem, tab sis nrog ib tug ntau ntawm koj lem. Ib tug thib ob winding - contrary tsawg heev tooj ntawm koj lem, tab sis ib tug loj hlau loj. Cov tub ntxhais thiab quab sau los ntawm hluav taws xob steel los xij, vim nws yog txig kev sib nqus flux. Nplooj ntawv yog cais los ntawm txhua lwm yam mus rau txo eddy currents thiab txo tus tub ntxhais tsis tau. Xws li ib tug los ua ke txoj kev nce efficiency (coefficient ntawm kev ua tau zoo).

Transformer ntaus ntawv tso cai cais lub tshuab txawm nyob rau ob peb thaj av. Piv txwv li, tus naj npawb ntawm theem ntawm cov transformer yog muab faib ua peb theem thiab ib theem. Lawv kuj qhia thiab rau lwm yam hom phiaj. Yeej, nws yog ua tau rau faib lub hwj chim thiab tshwj xeeb transformers. Apparatus hwj chim transformer tsim los rau cov kis tau tus mob thiab muab faib rau hluav taws xob lub zog. Tshwj xeeb transformers kuj yuav sib txawv heev - thiab qhov no welding, thiab xab, thiab kev soj ntsuam, thiab cub tawg thiab cov cuab yeej. Tsis tas li ntawd, lawv yuav tsum tau ntaus nqi, thiab nws pib-transformers (nyob rau hauv no hluav taws xob tshuab theem nrab thiab thawj windings yog kev cob cog rua nyob rau hauv ib tug hluav taws xob Circuit Court, tsim ib tug hluav taws xob kev twb kev txuas, thiab kuj, tsis yog sib nqus).

Cov transformers tsis txawv ntau heev nyob rau hauv lub tsim raws li zoo raws li lub hauv paus ntsiab lus ntawm tag nrho cov ua tau tib yam. Hais txog lub ntaus ntawv ntawm lub vuam transformer, piv txwv li, ib tug yuav hais tias nws nyob rau hauv tas li ntawd mus rau lub txwm hwj chim transformer ntxiv thiab tshwj xeeb ntaus ntawv, uas adjusts lub vuam tam sim no.
