Dab tsi yog cov teeb meem nrog transformer impedance voltage?

1. Tus qauv tus nqi ntawm transformer impedance voltage (tam sim no hu ua "luv-circuit impedance" nyob rau hauv tus qauv) yog qhia nyob rau hauv feem pua ​​(ib chav tsev nqi). Cov transformers sib txawv muaj cov qauv tsim nyog nyob rau hauv lub teb chaws tus qauv ntawm transformers. Txawm li cas los xij, qhov yuam kev yuav tshwm sim thaum lub tshuab hluav taws xob tsim khoom.
Qhov kev ua yuam kev yog: +7.5% rau -7.5% (yav dhau los +-10%). Yog tias tus qauv tus nqi ntawm koj lub transformer luv-circuit impedance yog 4%, nws yuav tsum tau xam raws li yav dhau los 10%, thiab transformer impedance ntau yuav tsum yog 3.6% -4.4% rau cov khoom tsim nyog. Thiab cov ntaub ntawv no yuav tsum tau muab luam tawm ntawm lub npe transformer. Yog hais tias nws yog tiag tiag li koj hais, nws tsuas yog hais txog 3.4% (tus qauv tus nqi ntawm kev faib me me transformers yog 4% lossis 4.5%), nws yuav yog cov khoom tsis tsim nyog. Nws raug nquahu kom koj xyuas kom zoo.
2. Qhov luv-circuit impedance ntawm transformer muaj feem xyuam rau ntau yam ntawm transformer. Xws li lub peev xwm, poob, sab hauv coil qauv ntawm transformer, thiab lwm yam. Tab sis ib zaug lub transformer yog tsim, nws yuav tsis hloov.
3. Qhov luv-circuit impedance no yog ib qho kev qhia tseem ceeb heev rau cov neeg siv. Piv txwv li, nws muaj feem xyuam rau kev ruaj ntseg ntawm lub hwj chim mov system, lub hwj chim mov zoo ntawm lub load, kev ruaj ntseg thiab kev cia siab ntawm lub transformer tom qab sib txuas kev twb kev txuas, thiab lwm yam.
4. Qhov luv-circuit impedance ntawm lub transformer yog nws tus kheej impedance. Lub impedance yog loj, thiab lub transformer yuav tsum tau tiv ib tug me me ntau yam ntawm luv luv-circuit tam sim no. Hais txog hais lus, lub luv luv-circuit kuj muaj zog, tab sis cov yam ntxwv sab nraud (volt-ampere yam ntxwv) ntawm transformer yog mos (raws li cov zis tam sim no ntawm lub transformer nce, nws cov zis voltage-- qhov voltage ntawm lub transformer kawg. poob heev). Ntawm qhov tsis sib xws, qhov luv-circuit impedance yog me me, thiab lub transformer yuav tsum tau tiv thaiv ib tug loj ntau yam ntawm luv luv-circuit tam sim no, yuav tsum tau lub transformer kom muaj zog luv luv-circuit resistance. Tau kawg, cov yam ntxwv sab nraud ntawm lub transformer yog qhov zoo.
5. Tsis tas li ntawd, qhov luv-circuit impedance tseem yuav cuam tshuam rau cov nqi tsim khoom ntawm lub transformer. Nws tsis yog qhov loj dua, lossis qhov me dua qhov zoo. Nws yuav tsum tau txiav txim siab dav, yog li muaj cov kev cai nruj hauv lub teb chaws tus qauv.
