Flux yog magnetic flux los yog magnetic fieldcreated nyob rau hauv lub hlau core ntawm lub transformer los ntawm ACcurrent ntws nyob rau hauv thawj winding. Ib ntus hloov magnetic teb tsim los ntawm AC siv rau lub hauv paus yog cov ntsiab lus uas AC voltage thiab tam sim no yog induced nyob rau hauv cov theem winding ntawm lub transformer.

Thiab cov lus nug yog, dab tsi yog magnetic flux hauv transformer?

A transformer muaj ob lub electrolyisolated coils thiab ua haujlwm ntawm Faraday tus thawj coj ntawm kev sib nrig sib. induction ”, nyob rau hauv uas EMF yog induced nyob rau hauv lub transformers Secondary kauj los ntawm sib nqus flux tsim los ntawm cov voltages thiab tam sim no ntws hauv thawj coilwinding.

Dab tsi yog flux ceev hauv transformer? Lub ncov flux ceev nyob rau hauv lub hauv paus ntawm lub transformer cuam tshuam los ntawm cov hauv qab no: Nws yog proportionalto RMS tus nqi ntawm qhov voltage thov rau thawj winding (xav tias nws yog sine yoj). Nws yog inversely proportional rau qhov cross-sectional cheeb tsam ntawm cov tub ntxhais nyob ib ncig ntawm uas lub winding yog muab tso rau.

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov xau flux hauv transformer?

Dej Flux hauv Hloov pauv Qhov no flux hu ua ntws flux uas yuav dhau los ntawm winding rwb thaiv tsev thiab transformer insulating roj es tsis txhob hla cov tub ntxhais. Vim qhov no ntws flux hauv transformer , ob qho tib si thawj thiab theem nrab windings muaj leak reactance.

Dab tsi yog ob lub ntsiab ntawm transformers?

Muaj peb hom thawj 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 cov hluav taws xob ntau dua vim yog tus nqi qis dua li electromagnetic VT.
