Rho tawm transformer - kev khiav hauj lwm hauv paus ntsiab lus thiab lub hom phiaj

Cais transformer - ib tug ntaus ntawv uas yog npaj rau lub thiaj li hu ua galvanic sib cais hluav taws xob kev pab thiab muab lawv mus rau lub mains.

Lub hom phiaj tseem ceeb ntawm xws li ib tug ntaus ntawv yuav tsum tau hu ua nce kev ruaj ntseg vim lub fact tias cov khoom xws li ib tug rho tawm transformer, tsis tuaj kawm ntawv nyob rau hauv lub thib ob Circuit Court nyob rau hauv hluav taws xob sib txuas lus nrog rau cov av los yog ib tug voltage qhov twg los, ua nyob rau hauv daim ntawv los yog earthed zoo earthed nruab nrab ntawm transformer substations.

Nyob rau hauv no qhov teeb meem no txawm tias ib tug tau tshwm sim ntawm hluav taws xob neej puas nyob rau hauv lub txee yuav tsis ua rau ib tug ntau dhau nyob rau hauv lub fais poob siab. Tus ntaus ntawv nws tus kheej yuav yog li nyob twj ywm kiag li ua hauj lwm zoo thiab zoo. Accidental kov ub kov no ntawm lub ntaus ntawv mus rau tus neeg, uas, ntsig txog, yog nyob rau hauv thaum muaj xwm ceev voltage, to tam sim no tsis pub tshaj zhiznennoopasnogo theem rau tib neeg, thiab raug xwm txheej yuav tsum tau zam.

Ib tug rho tawm transformer yuav tsis tau superfluous, tsis tsuas nyob rau hauv kev lag luam, tab sis txawm nyob rau hauv lub tsev. Tshwj xeeb tshaj yog yog hais tias muaj yog ib lub tsev rhiav.

Hauv plawv ntawm xws li raws li ib tug transformer cais dag lub thiaj li hu ua TS (standardized transformer). Txij li thaum cov niaj hnub tsev neeg hluav taws xob khoom siv tuaj nyob rau hauv txawv zog noj thiab hwj chim transformers kuj noj koom nrog cov expectation ntawm ib tug ntau yam ntawm hom ntawm load thiab lub load peev xwm.

Cov nyhuv sib cais thiab tsis muaj kev siv hluav taws xob coupling (uas yuav coj mus rau hauv lub thiaj li hu ua galvanic rho tawm voltage uas pub tau mov rau tus ntaus ntawv, thiab cov voltage uas yog nkag los ntawm cov hluav taws xob mov kab) yog tiav heev tsuas. Cais transformer muaj ob tug windings nyob rau hauv lawv cov kev tsim kho - theem nrab thiab thawj. Nruab nrab ntawm lawv yog ntsia tam (yam tsawg kawg ob) kev rho tawm los yog hlau grounded kais uas saib kuas kom tsis txhob rhuav tshem. Txij li thaum lub rho tawm transformer yog tsis haum rau converting ib tug voltage, nws transformation piv no feem ntau yog sib npaug zos rau kev sib sau. Lub voltage ntawm lub tswv yim yuav sib txawv los ntawm lub voltage ntawm cov qhov tso zis.

Txawm li cas los, dab tsi yog qhov point uas siv xws li ib tug transformer? Qhov no yog ua los ntawm cov piv txwv, yog hais tias nyob ib noo qhov chaw, piv txwv li, muaj elektrotochka tsis galvanic rho tawm nyob rau hauv lub chav da dej. Yog hais tias nyob rau ntawm no point ntub, lub rwb thaiv tsev neej puas tshwm sim. Raws li ib tug tshwm sim, ib tug tej yam seem ntawm cov phab ntsa thiab ungrounded hluav taws xob khoom siv tom ntej no mus nws yuav ua tau nyob rau hauv tej yam ntawm kev nyuaj siab.

Yog hais tias muaj yog ib tug rhuav tshem ntawm rwb thaiv tsev thiab ib tug rho tawm transformer, tib ib feem ntawm cov phab ntsa kuj yuav energized, tab sis nyob rau hauv cov ntaub ntawv no, tam sim no yuav tsum tau tsawg heev heev. Thiab yog hais tias muaj yog tsis muaj rwb thaiv tsev neej puas, muab xam rau ntawm ib tug ntaus ntawv xws li ib tug rho tawm transformer, yog xaiv kom raug, qhov tam sim no los yog voltage yuav tsis muaj nyob rau tag nrho.

Xws li ib tug ntaus ntawv feem ntau siv nyob rau hauv meditsine.Est tau siv nws li ib tug tso zis yog raws li ib tug transformer coupling transformer kev txuam network impedance.
