A voltage transformer(PT) yog hom tshwj xeeb ntawm transformer uas nws lub luag haujlwm tseem ceeb yog hloov siab -voltage systems rau hauv qis-voltage signals los pab kom muaj kev nyab xeeb ntawm kev tiv thaiv, ntsuas, thiab cov cuab yeej tswj. Hauv cov tshuab hluav taws xob, vim yog kev ua haujlwm thiab kev nyab xeeb, siab - cov kab hluav taws xob feem ntau tsis ntsuas ncaj qha; yog li ntawd,voltage transformersyog siv los txo qhov voltage.
Qhov thib ob voltage ntawm lub voltage transformer yog tsau ntawm 100 volts, feem ntau yog vim li cas hauv qab no:
Standardization
Tsim kom muaj tus qauv theem nrab voltage ua kom yooj yim rau kev tsim thiab tsim cov txheej txheem thiab ua kom yooj yim rau kev tsim thiab calibration ntawm cov twj paj nruag thiab relays. Txhua qhov hluav taws xob hloov hluav taws xob-raws li cov khoom siv tuaj yeem xav tias yuav muaj qhov hluav taws xob zoo ib yam, tshem tawm qhov kev xav tau tshwj xeeb rau kev hloov pauv ntawm cov qib sib txawv.
Kev nyab xeeb
100 volts yog ib qho hluav taws xob tsis tshua muaj hluav taws xob, txo qhov kev pheej hmoo ntawm hluav taws xob poob siab rau cov neeg ua haujlwm thiab cov khoom siv, txawm tias nyob rau hauv qhov teeb meem txhaum cai, yog li txhim kho kev nyab xeeb ntawm thaj chaw.
Instrument Transformer Tsim
Raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, qhov thib ob voltage ntawm lub ntsuas ntsuas transformer yog proportional rau thawj voltage thiab ywj siab ntawm theem nrab load kuj. Los ntawm kev xaiv qhov tsim nyog winding piv, qhov hluav taws xob theem nrab ntawm kwv yees li 100 volts tuaj yeem ua kom ntseeg tau hauv ntau yam kev siv tau zoo thaum tswj hwm lub zog xa mus rau cov khoom ntsuas.
Kev ntsuas qhov tseeb
Ntawm qhov tsis tshua muaj hluav taws xob, cov cuab yeej thiab cov relays yog qhov tseeb dua vim tias lawv tsis tshua muaj kev cuam tshuam rau qhov kub thiab txias, kev laus, thiab lwm yam ib puag ncig.
Kev lag luam
Ib qho hluav taws xob ruaj khov thib ob txo cov hom ntsuas ntsuas hluav taws xob, ua kom yooj yim tswj cov khoom muag, thiab tseem txo cov nqi tsim khoom.
Raws li txoj cai ua haujlwm ntawmTom ntej: JDZW-35 Voltage Transformer, nws ua raws Faraday txoj cai ntawm electromagnetic induction. Thaum thawj kauj ruam txuas nrog AC lub zog, qhov chaw sib nqus sib nqus yog tsim nyob rau hauv nws. Qhov chaw sib nqus no dhau los ntawm cov kauj theem ob, ua rau nws tsim hluav taws xob hluav taws xob (EMF). Qhov loj ntawm EMF yog txiav txim los ntawm cov qauv hauv qab no:
[ E_2=N_2 ∫_0^2 dPhi}{dt} ]
Qhov twg:
• ( E_2 ) yog qhov voltage thib ob.
• ( N_2 ) yog tus naj npawb ntawm lem nyob rau hauv lub thib ob kauj.
• ( ∫_0^2 dPhi}{dt} ) yog tus nqi ntawm kev hloov ntawm magnetic flux, uas muaj feem xyuam rau thawj voltage thiab tus naj npawb ntawm lem (N_1) ntawm thawj kauj.
Raws li qhov sib piv ((N_1): (N_2)) ntawm cov thawj thiab theem nrab ntawm covvoltage transformer, peb tuaj yeem xam qhov voltage thib ob (E_2). Piv txwv li, yog tias thawj sab yog 10kV thiab sab thib ob yog 100V, ces peb tuaj yeem teeb tsa kev sib raug zoo ntawm (N_1) thiab (N_2) xws li (\\frac{N_1}{N_2}=\\frac{10000}{100}=100), yog li ntawd ntawm tib zaus, qhov nruab nrab ntawm qhov voltage 0.
Txawm li cas los xij, hauv kev siv tswv yim, peb tsis tas yuav nruj me ntsis lav tias qhov hluav taws xob theem nrab yog tas li ntawm 100 volts. Lwm cov kev qhia tshwj xeeb kuj muaj, xws li 57.7 volts (rau theem voltage ntsuas nyob rau hauv peb-theem systems) los yog 100/3 volts (rau kab voltage ntsuas hauv peb-theem systems). Cov kev ntsuas sib txawv no yog los ua kom haum raws li qhov xav tau ntawm qhov sib txawv voltage theem thiab daim ntawv thov scenarios.
