Dab tsi yog impedance voltage ntawm ib transformer coopleplate?

Dab tsi yog impedance voltage?

Impedance voltage, tseem hu ua luv - Circuit Court, sawv cev rau cov hluav taws xob tsis dhau tus tshuab hluav taws xob thaum muaj rated tam sim no los ntawm nws. Luv - Circuit Court sab nraud (feem ntau yog qhov qis- voltage ntawm qhov ntsuas hluav taws xob rau thawj sab. Thaum qhov ntsuas ntawm qhov chaw nyob dhau ntawm sab nraud, cov voltage thib ob yog feem ntau hais ua feem pua, xws li UZ%. Cov lus txhais no cov feem pua ​​ntawm luv {{

Kev suav: luv {- Circuit Court sab nraud ntawm qhov thib ob transformer thiab maj mam thov voltage rau thawj sab. Thaum Rated tam sim no ntws los ntawm cov winding thib ob, feem pua ​​piv ntawm cov voltage un yog xam: uz% {2} × 100%

Lub hom phiaj ntawm kev yuam kev voltage yog dab tsi?

Luv - Circuit Court yuam kev txiav txim siab qhov ntau ntawm cov kab ke luv luv ntawm lub cev, thiab yog li qhov ntau ntawm cov hluav taws xob hauv hluav taws xob tsis pub dhau lub transformer. Nws tseem txiav txim siab qhov hloov hluav taws xob ntawm lub thauj ntawm cov transformer ntawm cov hloov pauv hloov, cuam tshuam voltage hloov pauv thaum lub lag luam kev ua haujlwm. Luv - Circuit Circuitance tseem yog qhov tsim nyog rau cov kev ua haujlwm sib hloov ntawm kev hloov pauv.

Cov hau kev rau kev ntsuas kev cuam tshuam voltage

Choj Tus Qauv:Qhov no yog ib txoj kev ntsuas ntsuas raws li ntawm tus Choj Sib Pauv Txoj Cai los txiav txim siab luv {} Circuit Impedance tus nqi.

 Luv - Circuit Court qhov qis - voltage sab ntawm lub transformer.

 Tom qab ntawd siv tus choj txuas rau qhov siab - voltage sab.

 Kho tus choj mus ua tiav qhov sib npaug; Tus nqi ntsuas tau muab cov lus luv luv - Circuit Court Impedance.

Cov qauv no muaj qhov yog tab sis yog cov ua haujlwm thiab yuav tsum muaj cov neeg ua haujlwm txawj ntse.

Cov kev ua tau zoo ntawm impedance voltage

Los ntawm cov saum toj no, nws yog tseeb tias impedance voltage yog qee qhov tsis sib haum xeeb hauv kev siv.

Los ntawm cov kev ua haujlwm ua haujlwm ntawm kev ua haujlwm pom kev pom zoo:

Rau kev hloov pauv ntawm tib lub peev xwm, qis dua cov neeg siv hluav taws xob txhais tau tias tus nqi qis dua, kev pheej yig dua, pheej yig dua, thiab kev ntsuas hluav taws xob zoo dua qub. Yog li ntawd, los ntawm qhov kev pom ntawm kev ua haujlwm nyuaj, cov impedance impedance voltage yog qhov zoo dua.

Los ntawm luv - Circuit Court tam sim no txwv tsis pub muaj kev pom:

Txawm li cas los xij, los ntawm qhov kev pom ntawm kev txwv luv - Circuit Cours (xws li cov khoom siv hluav taws xob (kab ke) los ntawm kev puas tsuaj thaum lub sijhawm ua haujlwm, ntau dua cov kev tsim hluav taws xob, hluav taws xob siab dua.

Cov ntaub ntawv thov piv txwv:

Hauv nroog fais fab ci, vim muaj qhov tseem ceeb load hloov pauv hloov pauv, hloov siab dua {{Circuit Coistance raug xaiv kom ntseeg tau cov kev ruaj khov. Piv txwv li, hauv thaj chaw nruab nrab hauv nroog, hloov pauv nrog 7% luv {{{- Circuit Court tau raug hloov pauv los ntawm kev hloov pauv hloov. Piv nrog transformers nrog 5% impedance, cov hloov hluav taws xob muab cov qauv hluav taws xob zoo dua hauv qab cov voltage thiab muaj zog ruaj khov rau cov neeg siv.

Txhawm rau kom haum rau qhov xav tau ntawm kev ua haujlwm ib txwm muaj thiab cov xwm txheej ua txhaum, iec qhia meej cov kev xav tau rau ntau hom transformer. Feem ntau, qhov siab dua qhov ntsuas hluav taws xob ntau dua, qhov loj dua lub impedance voltage muaj nuj nqis:

Lub zog hloov hluav taws xob ntawm 6 ~ 10 KV qib: 4% - 5.5%

Lub zog hloov hluav taws xob ntawm 35 kV qib: 6.5% - 8%

Lub zog hloov hluav taws xob ntawm 110 KV qib: 8%- 9%

Lub zog hloov hluav taws xob ntawm 220 KV qib: 12% - 14%

Qhov txheej txheem ntawm kev cuam tshuam voltage pab pab kom ntseeg tau tias transformers ntawm ntau hom thiab kev ntsuas tuaj yeem ua haujlwm nyab xeeb thiab ntseeg tau.
