Peb-theem peb-ntxhais kem yog muab peb lub windings ntawm peb theem ntawm peb cov kab ke raws li, thiab peb cov tub ntxhais kab tseem txuas nrog rau sab sauv thiab qis hlau yokes los tsim ib lub voj voog kaw sib nqus. Kev npaj ntawm windings yog tib yam li ntawm ib theem transformer. Piv nrog rau peb-theem hlau tub ntxhais, peb-theem tsib-ntxhais kem muaj ob ceg ntxiv hlau cores nyob rau sab laug thiab sab xis ntawm cov tub ntxhais hlau, uas dhau los ua ib qho kev hla. Lub windings ntawm txhua theem voltage yog feem ntau lub tes tsho nyob rau hauv nruab nrab peb cores raws li theem, thaum lub sab yoke tsis muaj windings, yog li tsim ib tug peb-theem tsib-core kem transformer.
Vim tias qhov sib nqus flux ntawm txhua theem ntawm peb-theem tsib-kem hlau tub ntxhais tuaj yeem raug kaw los ntawm sab yoke, peb-theem magnetic circuits tuaj yeem suav tias yog kev ywj pheej ntawm ib leeg, tsis zoo li cov qauv peb-theem peb-kem transformer. nyob rau hauv uas lub magnetic circuits ntawm txhua theem yog interrelated. Yog li ntawd, thaum muaj asymmetric load, xoom-sequence magnetic flux generated los ntawm xoom-sequence tam sim no ntawm txhua theem yuav raug kaw los ntawm lub sab yoke, yog li nws zero-sequence excitation impedance yog sib npaug zos rau symmetrical ua hauj lwm (zoo ua ntu zus) .
Peb-theem thiab peb-kem transformers nrog nruab nrab thiab me me tau txais yuav. Lub peev xwm loj peb-theem transformer feem ntau txwv los ntawm kev thauj mus los qhov siab, thiab peb-theem tsib-kem transformer feem ntau siv.
Hlau-plhaub ib-theem transformer muaj ib qho tseem ceeb hauv nruab nrab kem thiab ob ceg tub ntxhais kab (tseem hu ua sab yokes), thiab qhov dav ntawm lub hauv paus core kem yog qhov sib npaug ntawm qhov dav ntawm ob ceg tub ntxhais kab. Tag nrho cov windings tau muab tso rau ntawm lub hauv paus tseem ceeb, thiab ob ceg tub ntxhais kab nyob ib puag ncig sab nraud ntawm cov windings zoo li "plhaub", yog li nws yog hu ua plhaub transformer. Qee lub sij hawm nws tseem hu ua ib-theem peb-kem transformer.
