Lub peev xwm ntawm hlau lossis hlau nqa cov hlau nplaum sib nqus yog ntau dua li huab cua. Qhov peev xwm nqa tau flux hu ua permeability. Yog li hlau core yog siv nyob rau hauv transformer nyob rau hauv qhov chaw cua core. … Cov transformers zoo li no tsis muaj txiaj ntsig vim qhov feem pua ntawm cov flux los ntawm thawj kauj uas txuas lub kauj thib ob yog me me.

YYuav siv cov hlau nplaum hauv transformer yog dab tsi?

Lub luag haujlwm ntawm cov tub ntxhais sib nqus hauv cov tshuab hloov pauv feem ntau tau hais tias yognce thiab mloog zoo rau cov hlau nplaum sib nqus uas txuas rau lub hauv paus thiab theem nrab coils.

Vim li cas transformers siv hlau cores?

Hauv kev hloov pauv tiag tiag, ob lub coils raug mob rau tib lub core hlau. … Lub hom phiaj ntawm cov tub ntxhais hlau yog txhawm rau xa cov hluav taws xob sib nqus tsim los ntawm cov tam sim no ntws nyob ib ncig ntawm lub hauv paus kauj, kom ntau npaum li qhov ua tau kuj txuas rau theem ob.

Vim li cas cov tub ntxhais transformer yog ua los ntawm nyias laminated ferromagnetic khoom?

Iron core yog nyias & laminated hauv transformer kom tsis txhob poob ntawm eddy tam sim no. Eddy tam sim no yog induced nyob rau hauv cov tub ntxhais thiab circulates ib txwm mus rau qhov dav ntawm cov tub ntxhais ua rau cua sov.

Cov khoom siv twg yog siv rau hauv cov tub ntxhais transformer?

Ib qho ntxiv me me ntawm silicon rau hlau (ze li 3%) ua rau muaj kev nce siab ntawm cov hlau, mus txog plaub zaug siab dua. Qhov siab dua resistivity txo cov eddy tam sim no, yog lisilicon steel yog siv hauv transformer cores.

Nyob rau hauv cov khoom siv ferromagnetic?

Nyob rau hauv cov khoom siv ferromagnetic?

Ferromagnetism yog ib hom hlau nplaum uas cuam tshuam nrog hlau, cob alt, npib tsib xee, thiab qee cov alloyslossis cov tebchaw uas muaj ib lossis ntau dua ntawm cov ntsiab lus no. … Hauv qab ntawm Curie point, atoms uas coj li cov hlau nplaum me me hauv cov khoom siv ferromagnetic spontaneously dlhos lawv tus kheej.

Vim li cas transformer ntsuas hauv kva?

Vim li cas transformer ntsuas hauv kva?

Transformers raug ntsuas nyob rau hauv kVA vim qhov poob tshwm sim hauv cov transformers yog ywj siab ntawm lub hwj chim yam. KVA yog lub zog ntawm lub zog. Nws yog kev sib txuas ntawm lub zog tiag tiag thiab lub zog reactive. Transformers yog tsim los yam tsis xav txog kev thauj khoom txuas.

Vim li cas cov khoom siv dielectric siv hauv capacitor?

Vim li cas cov khoom siv dielectric siv hauv capacitor?

Ib qho khoom siv dielectric yog siv los cais cov paib hluav taws xob ntawm lub capacitor. Cov khoom siv insulating no tseem ceeb txiav txim siab txog cov khoom ntawm cov khoom. Lub dielectric qhov tsis tu ncua ntawm cov khoom txiav txim siab npaum li cas ntawm lub zog uas lub capacitor tuaj yeem khaws cia thaum siv hluav taws xob.

Vim li cas fe yog ferromagnetic?

Vim li cas fe yog ferromagnetic?

Qhov kev nkag siab nrov ntawm cov khoom sib nqus yog ferromagnetism, xws li hlau, Fe. … Yog li ntawd, ob lub electrons ua ke nyob rau hauv tib lub orbit yuav tsum muaj ib tug nce thiab ib tug down spin - lub net spin thiab yog li ntawd cov hlau nplaum yog xoom.

Vim li cas bushing siv hauv transformer?

Vim li cas bushing siv hauv transformer?

Cov bushings siv rau qhov tsis tshua muaj hluav taws xob winding (s) ntawm lub tshuab hloov pauv feem ntau yog hom khoom nrog cov plooj (porcelain) lossis epoxy insulator. … Lawv lub hom phiaj yog tswj qhov hluav taws xob nyob ib puag ncig ntawm tus neeg xyuas pib kom qhov hluav taws xob faib ntau yam sib xws thoob plaws cov kab hluav taws xob nyob ib puag ncig hauv bushing.
