Voltage hloov yog qhov tseem ceeb ntawm hluav taws xob engineering, ua rau lub luag haujlwm tseem ceeb hauv kev nyab xeeb thiab kev ua haujlwm ntawm cov tshuab hluav taws xob. Cov lus no rho tawm mus rau qhov hluav taws xob hloov pauv tau siv rau thiab paub meej txog qhov sib txawv ntawm cov hluav taws xob voltage thiab cov kev hloov pauv.
Dab tsi yog qhov hluav taws xob hloov hluav taws xob?
A Voltage Transformer(VT) yog lub cuab yeej hluav taws xob tsim los hloov cov qib hluav taws xob siab kom qis dua cov qib. Qhov kev hloov pauv no yog qhov tseem ceeb rau kev ntsuas kev nyab xeeb, tshuaj xyuas, thiab tswj cov hluav taws xob hluav taws xob. Kev hloov hluav taws xob hloov hluav taws xob feem ntau yog siv rau hauv cov khoom siv hluav taws xob, kev siv hluav taws xob ua kom paub meej tias cov qib hluav taws xob muaj kev nyab xeeb.
Siv Kev Hloov Hluav Taws Xob
Kev ntsuas thiab saib xyuas: Voltage hloov hluav taws xob tau siv dav hauv lub zog ntawm cov tshuab ntsuas kom ntsuas cov kev ntsuas siab. Los ntawm stepping nqes qhov voltage rau theem qis dua, lawv tso cai rau kev ntsuas raug thiab nyab xeeb siv cov twj txheem txheem txheem.
Kev tiv thaiv: ua ke nrog kev sib cog lus, voltage hloov pauv pab hauv kev txheeb xyuas qhov xwm txheej tsis zoo xws li-voltage lossis under-voltage. Qhov no ua rau lub kaw lus los ua cov kev kho kom zoo, xws li cais tawm cov lus tsis raug los tiv thaiv kev puas tsuaj thiab ua kom muaj kev nyab xeeb.
Kev tswj: voltage transformic muab cov theem voltage tsim nyog rau kev tswj cov circuits hauv ntau yam khoom siv hluav taws xob nyob rau hauv ntau yam hluav taws xob thiab tshuab. Qhov no ua kom ntseeg tau tias kev tswj cov txheej txheem ua haujlwm kom raug thiab muaj txiaj ntsig.
Kev Rho Tawm: Lawv muab hluav taws xob rho tawm ntawm cov hluav taws xob siab thiab ntsuas hluav taws xob qis thiab ntsuas kev nyab xeeb thiab txo qhov kev pheej hmoo ntawm kev ua haujlwm hluav taws xob.
Qhov sib txawv ntawm ib tug muaj peev xwm hloov pauv thiab aVoltage Transformer
Cov lus cog lus "Cov hloov peev xwm hloov pauv" (PT) thiab "voltage transformer" (vt) feem ntau siv sib pauv sib hloov, tab sis muaj kev sib txawv sib txawv tsim nyog.
Muaj nuj nqi thiab daim ntawv thov
Voltage transformer (VT): Feem ntau, lub sij hawm vt yog siv los piav qhia cov hloov pauv uas nce qib siab rau kev ntsuas, thiab tswj hwm. Lawv tsim los tswj hwm ntau yam ntawm voltuage thiab siv nyob rau hauv ntau yam kev siv, suav nrog kev faib khoom siv fais fab thiab kev lag luam lag luam.
Muaj peev xwm hloov tau(PT): PTs yog ib hom hluav taws xob tshwj xeeb feem ntau siv rau kev ntsuas voltage hauv kev ntsuas hluav taws xob. Lawv tau tsim los muab cov sawv cev muaj tseeb ntawm thawj qhov chaw voltage rau sab ob, ua kom tiav kev nyeem ntawv rau kev xa nqi thiab saib xyuas lub hom phiaj thiab saib xyuas lub hom phiaj.
Raug:
Voltage transformer (VT): thaum VTS yog qhov tseeb, lawv lub hom phiaj tseem ceeb yog nyob rau kev nyab xeeb thiab tswj voltage theem rau ntau yam kev siv. Tej zaum lawv yuav tsis muaj tib theem ntawm qhov tseeb raws li pts.
Tej zaum yuav hloov tau (PT): PT): PT): PT): PT): PTT yog tsim muaj qhov tseeb hauv siab, feem ntau sib ntsib cov qauv nruj me ntsis kom ntseeg tau tias ntsuas hluav taws xob. Qhov no ua rau lawv zoo tagnrho rau metering thiab lwm yam kev siv uas yog qhov tseeb ntawm qhov tseeb.
Tsim thiab Kev Siv:
Voltage transformer (VT): VTS tuaj yeem sib txawv hauv kev tsim qauv raws li lawv cov kev siv tshwj xeeb-qis-hauv cov qauv nrog ntau cov cua thiab cov ntau ntxiv.
Muaj peev xwm hloov tau (PT): PT yog tsim qauv nrog kev tsom xam cov ntaub ntawv thiab kev siv zog siv los txo qhov yuam kev thiab ua kom muaj kev ntseeg tau ntev.

Cov kev hloov hluav taws xob hloov kho yog qhov tsis tseem ceeb hauv cov tshuab hluav taws xob, muab cov haujlwm tseem ceeb xws li kev ntsuas, kev tswj hwm, tswj, tswj, thiab cais. Thaum cov ntsiab lus voltage transformer thiab cov hloov hluav taws xob feem ntau siv sib hloov, nkag siab txog lawv qhov sib txawv yog qhov tseem ceeb rau kev xaiv cov cuab yeej tshwj xeeb. Voltage hloov muab cov kev ua haujlwm dav dav, thaum muaj peev xwm hloov pauv tau tshwj xeeb rau kev ntsuas voltage. Ob lub luag haujlwm tseem ceeb tshaj plaws hauv kev ua kom muaj kev nyab xeeb, ua haujlwm, thiab kev ntseeg tau ntawm hluav taws xob hluav taws xob.
