TTR Tester yog hais txog qhov hloov pauv hloov pauv hloov pauv
Transformers zoo hloov hluav taws xob hluav taws xob los ntawm ib lub voj voog mus rau lwm qhov los ntawm kev sib nqus induction. Txhua theem ntawm lub transformer yog tsim los ntawm ob tug ywj siab coil windings raug mob nyob ib ncig ntawm tib lub core.
Thawj winding ntawm lub transformer tau txais hluav taws xob hluav taws xob los ntawm lub zog hluav taws xob. Thaum thawj winding yog energized los ntawm alternating tam sim no (AC), alternating magnetic kab hu ua "flux" circulate nyob rau hauv lub hlau core, tsim ib tug magnetic teb.
Qhwv qhov thib ob winding nyob ib ncig ntawm tib lub sib nqus core, thiab lub magnetic teb yuav induce voltage. Qhov winding no hu ua Secondary winding. Tus nqi ntawm qhov voltage induced nyob rau hauv txhua qhov tig ntawm qhov thib ob winding yuav zoo ib yam li qhov voltage induced nyob rau hauv txhua qhov tig ntawm thawj winding. Qhov no hu ua transformer ratio.
Yog hais tias tus naj npawb ntawm lem nyob rau hauv lub thib ob winding yog tsawg tshaj li nyob rau hauv thawj winding, ib tug qis voltage yuav induced nyob rau hauv lub thib ob winding. Hom transformer no hu ua step-down transformer.
Tus naj npawb ntawm cov lem ntawm ob kauj ruam yog ob zaug ntawm thawj kauj, uas yuav raug txiav los ntawm ob zaug lub sib nqus flux thiab induce ob zaug ntawm thawj voltage nyob rau hauv lub thib ob kauj. Qhov no transformer yog hu ua step-up transformer.
