Lub hom phiaj thiab cov qauv ntawm Kev Ntsuas Transformer Voltage Ratio & Vector Group
Transformers yog ib qho tseem ceeb ntawm cov tshuab hluav taws xob uas tso cai rau kev sib kis tau zoo thiab kev faib hluav taws xob. Xyuas kom meej tias cov transformers ua haujlwm raug yog qhov tseem ceeb, thiab ib txoj hauv kev ua kom tiav qhov no yog los ntawm kev ntsuas qhov sib piv ntawm transformer voltage thiab vector pawg.
Qhov sib piv voltage yog suav tias yog qhov piv ntawm qhov tsis muaj qhov hluav taws xob ntawm HV- thiab LV-sab. Vector pawg thiab lawv cov yam ntxwv tsuas yog txhais rau poly-theem transformers. Lawv tuaj yeem txuas nrog instar-, delta- lossis zigzag-kev sib txuas, nyob ntawm qhov yuav tsum tau ua. Cov theem hloov ntawm cov windings tuaj yeem cuam tshuam tsis pub dhau 30 degree - cov kauj ruam ntawm 0 degree mus rau 330 degree, uas nyob ntawm txoj kev sib txuas. Transformers 'kev ua haujlwm sib luag xav tau qhov zoo sib xws tsis muaj qhov sib piv thiab tib pawg vector. Txwv tsis pub, circulating tam sim no yuav tshwm sim ntawm lub parallel transformers, uas yuav tsum tau zam. Qhov sib piv ntawm qhov voltage thiab theem hloov pauv yog qhov tseem ceeb ntawm kev txaus siab thaum nws los txog rau kev ua haujlwm sib luag nrog ob lossis ntau dua transformers.
Txuj kev ntsuas transformer voltage piv & vector pawg
IEC60076-1Clause 6: "Kev sib txuas thiab hluav taws xob hloov hluav taws xob cim rau peb-theem transformers" Nqe 10.3: "Kev ntsuas qhov ntsuas qhov sib piv thiab kuaj cov theem hloov pauv"
IEEEC57.12.90Clause 6: "Polarity and the phase relation test" Nqe 7: "Kev ntsuam xyuas piv"
Cov pawg vector feem ntau raws li IEC 60076-1
Ntsuas transformer voltage piv thiab vector crew yog qhov tseem ceeb rau kev khaws cia haum rau kev ua haujlwm, kuaj xyuas qhov tsis raug, ua kom yooj yim txij nkawm, thiab ua kom tsim nyog rau kev teeb tsa. Tsis tas li ntawd, cov kev ntsuas no tuaj yeem tiv thaiv kev puas tsuaj rau cov cuab yeej thiab txhim kho lub zog ua haujlwm. Yog li ntawd, nws yog ib qho tseem ceeb rau kev coj cwj pwm cov kev kuaj xyuas no feem ntau thiab raug, nrog cov cuab yeej ua tau zoo thiab los ntawm cov kws tshaj lij.
