Lub pauv hloovyog cov khoom siv zoo li qub uas siv lub hauv paus ntsiab lus ntawm indectromagnetic induction hloov pauv ACT voltage. Nws lub ntsiab lus tseem ceeb yog thawj kauj, txheej txheem theem nrab, cov tub ntxhais hlau. Lub luag haujlwm tseem ceeb ntawm kev hloov pauv suav nrog kev hloov pauv hloov pauv, hloov dua siab tshiab, hluav taws xob tuaj yeem muab faib ua cov hluav taws xob hloov pauv tau raws li lawv siv. Lub ntsiab txheej txheem ntawm lub zog hloov hluav taws xob yog:
1. Rated Muaj Peev Xwm Sn
Lub sijhawm ntsuas muaj peev xwm ntawm tus hloov pauv yog hais txog lub zog loj ntawm tus siv hluav taws xob thaum lub sijhawm siv hluav taws xob tseem ceeb (cov ntsuas ntsuas
Ib leeg-theem hloov pauv SN=un2in2
Peb-theem hloov pauv SN=√3un2in2
2. Cov ntsuas hluav taws xob un1 thiab un2
Lub Koom Haum Kub Ntsuas Un1 yog sib npaug zos rau cov ntsuas hluav taws xob ntawm lub zog hluav taws xob un2 yog sib npaug ntawm cov khoom seem thaum lub ntsuas hluav taws xob ntxiv rau thawj sab.
Thawj qhov ntsuas tseem ceeb thiab theem nrab ntsuas ntawm peb-theem hloov pauv xa mus rau cov kab voltage.
Qhov ntsuas voltage piv hais txog qhov sib piv ntawm tus thawj ntsuas ntawm thawj qhov ntsuas hluav taws xob rau theem nrab rated voltage raws li tsis muaj kev thauj khoom. 3. Rated tam sim no In1 thiab In2
Qhov ntsuas nyob tam sim no ntawm thawj thiab theem nrab ntawm cov hloov pauv hais txog cov kab tam sim no uas tau tso cai rau lub sijhawm ntev thiab muaj qhov ntsuas kub.
Ib leeg-theem hloov pauv hauv 1= sn1 / un1
Hauv 2= sn2 / un2
Peb-theem hloov pauv hauv 1=} sn1 / √3un1
Hauv 2= sn2 / √3un2
4. Kev Ntsuas Hluav Taws Xob
Impedance voltage tseem hu ua luv luv-taws hluav taws xob voltage. Ntawd yog, kev txhaj tshuaj thib ob ntawm lub transformer yog luv-taws-taws, thiab cov hluav taws xob maj mam nce ntawm thawj lub winding. Thaum lub sijhawm luv luv-Circuit Cour tam sim no yog sib npaug rau qhov ntsuas uas muaj nyob tam sim no, qhov hluav taws xob siv rau thawj sab.
Kev tsim hluav taws xob sib luag yog ib qho ntawm cov xwm txheej rau kev ua haujlwm sib txuas ntawm ob lub transformers. Tus nqi ntawm luv luv-circuital voltage yog lub hauv paus saib xyuas cov luv luv hluav taws xob tam sim no thiab xaiv cov yam ntxwv relay tiv thaiv.
5. Tsis muaj-thauj khoom tam sim no kuv 0
Thaum ib sab thib ob ntawm tus transformer yog qhib thiab cov ntsuas hluav taws xob tau thov rau thawj sab, qhov tam sim no ntws los ntawm thawj lub winding yog tsis muaj-thauj khoom tam sim no. Qhov loj ntawm tsis muaj-thauj khoom tam sim no nyob ntawm lub peev xwm ntawm lub peev xwm ntawm cov qauv Circuit Court thiab qhov zoo ntawm cov khoom silicon steel. Tsis muaj-thauj khoom tam sim no ntawm cov kev faib dav dav dav dav yog 3% ~ 8% ntawm thawj qhov ntsuas uas tam sim no.
6. Tsis muaj-thauj khoom poob P 0
Hais txog lub hwj chim poob los ntawm tus hloov pauv thaum sab ob ntawm tus transformer yog qhib thiab cov ntsuas hluav taws xob tau thov rau thawj sab. Nws suav nrog kev ua kom zoo siab thiab eddy tam sim no poob. Qhov loj yog cuam tshuam nrog cov txheej txheem tsim khoom lag luam hloov kho thiab siv voltage, thiab tsis muaj dab tsi ua rau lub nra.
7. Luv-Circuit Cot Pk
Hais txog lub zog siv los ntawm tus hloov pauv thaum lub sijhawm thib ob ntawm lub transformer yog luv-ciruited thiab thawj winding hla qhov ntsuas nyob tam sim no. Nws tuaj yeem cuam tshuam txog kev lag luam kev lag luam ntawm tus hloov pauv.
8. Qhov kub nce siab
Lub xeev cov thwj tim hais tias qhov kev txwv ntawm qhov ntsuas kub nce ntawm cov roj sab saud ntawm lub transformer yog 55 degree. Txhawm rau tiv thaiv cov roj transformer los ntawm kev laus thiab tsis txaus ntseeg nrawm, qhov kub ntawm cov roj av sab saud ntawm lub transformer feem ntau tsis pub tshaj 85 degree.
9. Kev Txuas Khoom Sib Txuas
Cov pawg sib txuas ntawm tus hloov pauv yog hais txog kev sib txuas ntawm cov siab thiab qis voltage windings ntawm cov transformer thiab tus naj npawb dav dav sawv cev los ntawm lub moos ua ntu zus.
Cov ntaub ntawv sib txuas ntawm peb-theem winding ntawm lub transformer suav nrog lub hnub qub kev twb kev txuas thiab kev sib txuas txuas thiab nkhaus txuas. Lub High-voltage winding yog sawv cev los ntawm Y, D, thiab Z feem, thiab qhov qis-voltage winding yog sawv cev los ntawm Y, D, thiab Z feem. Thaum muaj ib qho nruab nrab ntawm taw tes ua, nws yog sawv cev los ntawm YN, ZN thiab YN, ZN feem.
Lub High-voltage winding ntawm cov transformer tsim nyob rau hauv kuv lub teb chaws tsis siv z txuas. Txhawm rau pab txhawb kev tswj cov khoom siv thiab ua haujlwm yooj yim, Yyn {} {}, thiab kua 0.
Cov pawg sib txuas ntawm lub transformer nrog kev voltage thib ob ntawm 4 {{}}}} Cov pab pawg sib txuas ntawm cov xob laim tiv thaiv transformer feem ntau yog adopts y, zn11.
