Lub zog hloov hluav taws xob yog ib hom hluav taws xob hloov hluav taws xob uas siv los hloov hluav taws xob hluav taws xob ntawm ob lossis ntau lub circuits los ntawm electromagnetic induction. Nws yog tsim los ua haujlwm ntawm high voltages thiab yog qhov tseem ceeb hauv kev sib kis thiab kev faib hluav taws xob. Fais fab transformers feem ntau pom muaj nyob rau hauv substations, qhov chaw uas lawv nqis mus rau high transmission voltages mus rau theem qis tsim nyog rau kev faib rau cov tsev thiab cov lag luam.
Thaum nws los txog rau lub zog ntsuas,fais fab mov transformersua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ntsuas qhov tseeb ntawm kev siv hluav taws xob. Lub zog ntsuas hluav taws xob, tseem hu ua watt-teev ntsuas ntsuas, yog cov khoom siv ntsuas cov hluav taws xob siv hluav taws xob los ntawm qhov chaw nyob, kev lag luam, lossis khoom siv hluav taws xob dhau sijhawm. Cov ntsuas no yog qhov tseem ceeb rau kev them nqi thiab saib xyuas kev siv hluav taws xob.
Feem ntau, tshwj xeeb tshaj yog nyob rau hauv cov chaw lag luam lossis cov tsev lag luam loj, cov qib voltage tuaj yeem siab dhau rau cov qauv ntsuas hluav taws xob los tswj ncaj qha. Qhov no yog qhov chaw fais fab transformers tuaj ua si. Lawv tau siv los nqis tes rau qhov siab voltage mus rau qis dua, tswj tau qib uas tuaj yeem ntsuas kev nyab xeeb ntawm lub ntsuas hluav taws xob. Cov txheej txheem no tsis tsuas yog tiv thaiv lub ntsuas hluav taws xob los ntawm kev puas tsuaj vim muaj hluav taws xob siab, tab sis kuj ua kom cov kev nyeem ntawv raug.
Fais fab transformers siv ua ke nrog lub zog ntsuas feem ntau hu ua "tam sim no transformers" (CTs) thiab "voltage transformers" (VTs). Tam sim no transformers yog siv los ntsuas qhov tam sim no ntws los ntawm ib tug neeg xyuas pib, thaum voltage transformers yog siv los ntsuas qhov voltage ntawm ib lub voj voog. Los ntawm kev siv cov transformers no, lub zog ntsuas tuaj yeem xam qhov kev siv hluav taws xob los ntawm kev sib npaug ntawm qhov ntsuas tam sim no thiab qhov hluav taws xob.
Kev sib koom ua ke ntawm cov hluav taws xob hloov hluav taws xob nrog cov ntsuas hluav taws xob yog qhov tseem ceeb tshwj xeeb hauv peb-theem tshuab, uas feem ntau siv rau hauv kev lag luam. Nyob rau hauv xws li cov tshuab, peb pawg ntawm tam sim no thiab voltages yuav tsum tau ntsuas ib txhij. Fais fab transformers pab txhawb qhov no los ntawm kev muab qhov tsim nyog scaling down ntawm cov hluav taws xob tsis, cia lub zog ntsuas mus ua hauj lwm zoo.
Ntxiv mus, kev siv ntawmfais fab mov transformershauv cov ntsuas hluav taws xob txhim kho kev nyab xeeb. Cov tshuab hluav taws xob siab tuaj yeem ua rau muaj kev pheej hmoo loj, suav nrog hluav taws xob poob siab thiab hluav taws kub. Los ntawm kev nqis qis ntawm qhov hluav taws xob mus rau qib kev nyab xeeb, lub zog hloov hluav taws xob pab txo cov kev pheej hmoo no, kom ntseeg tau tias ob lub zog ntsuas hluav taws xob thiab cov chaw nyob ib puag ncig ua haujlwm zoo.
Hauv cov ntsiab lus, lub zog hloov hluav taws xob yog qhov tseem ceeb hauv kev ua haujlwm ntawm lub zog ntsuas hluav taws xob, tshwj xeeb hauv kev siv hluav taws xob siab. Nws tso cai rau kev ntsuas qhov tseeb ntawm kev siv hluav taws xob los ntawm kev nce qib voltage mus rau qhov tswj tau ntau yam. Qhov no tsis yog tsuas yog ua kom paub meej cov nqi them nqi thiab saib xyuas kev siv hluav taws xob tab sis kuj tseem txhim kho kev nyab xeeb hauv cov tshuab hluav taws xob. Kev nkag siab txog lub luag haujlwm ntawm lub zog hloov hluav taws xob hauv cov ntsuas hluav taws xob yog qhov tseem ceeb rau txhua tus neeg koom nrog hauv kev lag luam hluav taws xob, vim nws qhia txog qhov tseem ceeb ntawm cov cuab yeej no hauv kev faib hluav taws xob kom zoo thiab nyab xeeb.
