Hluav taws xob transformer tau hloov alternatingcurrent (AC) voltage lossis hluav taws xob tam sim no los ntawm ib qib mus rau lwm qhov. Hwj chim yog sib npaug rau voltage zaus tam sim no. Transformerscan yeej tsis nce zog . Yog tias lawv qhov hluav taws xob nce ntxiv, tam sim no txo qis thiab yog tias lawv txo qhov voltage qhov tam sim no nce.

Raws li txoj cai, lub hwj chim transformer ua haujlwm li cas?

A transformer yog ib hluav taws xob apparatusdesigned los hloov alternating tam sim no los ntawm ib tug voltage rau lwm. Nws tuaj yeem tsim los "nce" lossis "qib nqis" voltagesand ua haujlwm nyob rau hauv txoj cai sib nqus induction. Ib qho voltage ishen induced nyob rau hauv lwm lub kauj, hu ua theem nrab los yog outputcoil.

Ib yam li ntawd, hluav taws xob transformers ua li cas? Feem ntau transformer coils yog ua los ntawm tooj liab hlau uas muaj kev tiv thaiv hauv Ohms, (Ω). Thaum lub load yog txuas nrog lub transformers Secondary winding, loj hluav taws xob cov dej ntws ntws hauv ob qho tib si thawj thiab cov kab sib txuas, hluav taws xob zog thiab zog (los yog I2 R) poob tshwm sim thaum tshav kub kub.

Ib yam li ntawd, nws tau nug, vim li cas Transformers nce voltage?

Siab hluav taws xob fais fab kis tau tus mob Qhov no txhais tau hais tias cov dej siab tam sim no siv hluav taws xob ntau dua li cov dej ntws qis. Txhawm rau txo cov kev hloov pauv hluav taws xob mus rau ib puag ncig, National Grid siv cov kauj ruam transformers rau nce tus hluav taws xob los ntawm cov chaw nres tsheb fais fab mus rau ntau txhiab volts, uas txo qis tam sim no hauv cov xaim hluav taws xob.

Dab tsi ntawm transformer siv nyob rau hauv cov chaw nres tsheb fais fab?

Muaj peb yam tseem ceeb hom ntawm voltage transformers (VT): electromagnetic, capacitor, thiab optical. The electromagnetic voltage transformer yog kab mob transformer . Lub capacitor voltage transformer siv acapacitance muaj peev xwm divider thiab yog siv ntawm high voltagesdue rau tus nqi qis dua ib qho hluav taws xob electromagnetic VT.
