Ib qho kev sib cais transformer yog ib qho khoom siv uas tsim los rau lub npe hu ua galvanic sib cais ntawm cov neeg siv hluav taws xob thiab cov khoom siv hluav taws xob uas pub rau lawv.
Lub luag haujlwm tseem ceeb ntawm cov cuab yeej no tuaj yeem raug hu ua kev nyab xeeb ntxiv vim tias cov khoom siv xws li kev sib cais transformer tsis muaj hluav taws xob sib txuas hauv ob lub voj voog nrog hauv av lossis nrog cov khoom siv hluav taws xob ua hauv daim ntawv. ntawm ib tug tuag-grounded los yog zoo grounded nruab nrab ntawm transformer substations.
Hauv qhov xwm txheej no, txawm tias qhov tshwm sim ntawm qhov tshwm sim ntawm hluav taws xob tawg ntawm rooj plaub yuav tsis ua rau muaj hluav taws xob ntau dhau. Cov cuab yeej nws tus kheej yuav nyob twj ywm hauv kev ua haujlwm zoo meej. Yog hais tias ib tug neeg yuam kev kov ib feem ntawm lub cuab yeej, uas, raws li, nyob rau hauv thaum muaj xwm ceev hluav taws xob, qhov to tam sim no yuav tsis pub dhau lub neej-kev hem thawj rau ib tug neeg, thiab vim li ntawd, qhov xwm txheej yuav zam tau.
Isolating transformer yuav pab tau tsis yog rau kev lag luam xwbkev lag luam, tab sis txawm nyob hauv tsev. Tshwj xeeb yog tias koj muaj kev cob qhia hauv tsev.
Lub hauv paus ntawm cov cuab yeej xws li kev hloov pauv hloov pauv yog qhov hu ua TC (kev sib koom ua ke transformer). Txij li cov khoom siv hluav taws xob hauv tsev niaj hnub tuaj nyob rau hauv ntau lub zog muaj peev xwm thiab muaj peev xwm, kev sib koom ua ke transformers kuj tau txais nrog kev cia siab ntawm ntau hom kev thauj khoom thiab thauj khoom muaj nuj nqis.
Cov txiaj ntsig ntawm kev sib cais thiab tsis muaj kev sib txuas hluav taws xob (uas ua rau lub npe hu ua galvanic cais tawm ntawm qhov hluav taws xob uas pub lub cuab yeej thiab qhov hluav taws xob uas tau muab los ntawm cov khoom siv hluav taws xob) tau ua tiav yooj yim heev. Ib qho kev sib cais transformer muaj ob lub windings nyob rau hauv nws tsim - theem nrab thiab thawj. Nruab nrab ntawm lawv, muaj zog (tsawg kawg yog ob npaug) rwb thaiv tsev los yog hlau av kais raug ntsia, uas ua rau nws muaj peev xwm los lav qhov kev zam ntawm kev tawg. Txij li thaum lub transformer cais tsis yog tsim los hloov voltage, nws transformation ratio feem ntau yog sib npaug rau ib. Nyob rau hauv cov ntaub ntawv no, lub input voltage yuav txawv ntawm qhov tso zis voltage.
Txawm li cas los xij, dab tsi yog qhov taw qhia ntawm kev siv lub tshuab hloov pauv? Qhov no yog ib qho yooj yim los ua piv txwv nrog ib qho piv txwv yog tias muaj qhov taw tes hluav taws xob yam tsis muaj kev sib cais ntawm cov galvanic hauv qhov chaw ntub dej, piv txwv li, hauv chav dej. Nyob rau hauv qhov kev tshwm sim uas ya raws nkag mus rau hauv xws li ib tug taw tes, ib tug tawg ntawm rwb thaiv tsev yuav tshwm sim. Yog li ntawd, ib qho ntawm cov phab ntsa thiab cov khoom siv hluav taws xob tsis muaj av nyob ib sab ntawm nws yuav poobkev nyuaj siab.
Yog tias muaj kev puas tsuaj ntawm cov rwb thaiv tsev thiab nrog kev sib cais transformer, ces tib qhov ntawm phab ntsa kuj tseem muaj zog, tab sis qhov no qhov tam sim no yuav tsawg tshaj plaws. Thiab yog tias tsis muaj kev cuam tshuam kev rwb thaiv tsev, kev suav ntawm cov cuab yeej xws li kev sib cais transformer raug xaiv kom raug, ces yuav tsis muaj tam sim no lossis voltage txhua.
Cov cuab yeej siv no feem ntau siv hauv tshuaj. Nws tuaj yeem siv los ua cov khoom siv hluav taws xob lossis ua cov sib txuas sib txuas kom haum rau qhov kev tiv thaiv ntawm Circuit Court.
