Txhawm rau kom ntseeg tau tias kev ua haujlwm zoo ntawm cov transformers, transformer voltage piv thiab polarity yog qhov tseem ceeb uas yuav tsum tau ntsuas kom raug. Transformer voltage piv thiab polarity yog qhov tseem ceeb uas yuav tsum tau ntsuas kom raug. Nws yog qhov yuav tsum tau ua kom muaj hluav taws xob sib kis tau zoo thiab kev xa tawm, thiab kev nyab xeeb ntawm cov khoom siv uas ntsuas qhov voltage piv thiab polarity kom raug.
Txoj kev ntsuas Voltage Ratio thiab Polarity ntsuas yog tib yam rau ib-theem raws li rau ob- thiab peb-theem cov cav tov Ua ntej energizing lub xeem Circuit Court, txhua tus neeg nyob rau hauv lub chaw ua hauj lwm yuav tsum tau qhia thiab qhia kom nyob twj ywm nyob rau hauv qhov tseeb thaum lub sij hawm kev ntsuam xyuas hluav taws xob. . Thaum xaiv cov
qhov tseeb voltages yuav tsum tau ntsuas thiab kaw rau ntawm datasheet rau qhov piv piv, xyuas kom meej tias tag nrho cov voltages yuav nyob rau hauv qab no theem txaus ntshai (tej zaum yuav muaj ib tug step-up voltage txaus ntshai). Nws tsis yog qhov ua tau zoo, thiab feem ntau tsis tuaj yeem ua tau, sim cov kev sim no ntawm qhov ntsuas tag nrho nrog cov
muaj cov cuab yeej xeem.
Tsis tas li ntawd, nco ntsoov tias ib qho winding txuas nrog theem rau theem thiab lwm qhov yog theem rau nruab nrab. Nco ntsoov tias qhov xav tau qhov hluav taws xob yog raws li qhov hloov pauv hloov pauv hloov pauv thiab tsis yog qhov sib piv kV (thawj mus rau theem nrab). Kev ceev faj, vim tias kev siv tsis raug ntawm qhov hluav taws xob tuaj yeem tsim kom muaj hluav taws xob tuag ntawm lub tshuab hluav taws xob terminals. Vim hais tias ntawm tes s-on xwm ntawm qhov kev xeem no, siv qhov ntsuas voltages rau qhov siab tshaj qhov hluav taws xob winding ntau dua li qhov
lwm txoj kev nyob ib ncig ntawm. Los ntawm cov tswv yim pom zoo, ib zaug ib-theem piv tau raug txiav txim siab, nws feem ntau tsis tsim nyog rau Ratio test peb-theem transformers los ntawm kev siv tsawg-magnitude peb-theem voltage.
Lub polarity ntawm cov windings tau yooj yim kuaj nyob rau tib lub sij hawm qhov voltage piv
kuaj. Qhov kev txhawj xeeb tseem ceeb thaum ua qhov kev kuaj xyuas polarity yog khi qhov tsis muaj polarity kawg ntawm ob qhov sib txawv windings ua ke thiab ntsuas thoob plaws polarity kawg. Qhov tshwm sim ntawm qhov hluav taws xob yuav yog qhov sib npaug lossis qhov sib txawv ntawm ob qhov sib txawv winding voltages, ib qho piv txwv qhia ntxiv thiab qhov sib txawv qhia qhov sib txawv polarity. Transformers siab tshaj 500 kVA yog tsim nrog cov polarity rho tawm.
