Yuav ua li cas xaiv lub peev xwm ntawm qhov ntsuas transformer?
Thaum nws los txog rau kev xeem hi-pot, lub peev xwm ntawm kev sim transformer plays lub luag haujlwm tseem ceeb. Lub hom phiaj ntawm qhov kev ntsuam xyuas hi-pot yog txhawm rau txheeb xyuas qhov muaj peev xwm tsis muaj zog hauv cov hluav taws xob rwb thaiv tsev, thiab qhov kev ntsuam xyuas kev ntseeg tau yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig raug thiab zoo ib yam. Lub peev xwm ntawm kev sim transformer, los yog nws lub peev xwm los muab qhov tsim nyog voltage thiab tam sim no, yog qhov tseem ceeb thaum xaiv chav tsim nyog rau koj qhov kev xav tau.
Txhawm rau txiav txim siab lub peev xwm zoo tshaj plaws ntawm koj qhov kev sim transformer, koj yuav tsum xav txog ntau yam. Thawj qhov yog qhov siab tshaj plaws voltage thiab tam sim no uas koj yuav tsum tau ua kom tiav thaum kuaj. Tus nqi no yuav nyob ntawm seb cov khoom siv tshwj xeeb raug kuaj thiab cov kev cai ntawm kev lag luam uas siv. Piv txwv li, ib qho kev hloov pauv rau kev sim cov cuab yeej kho mob yuav xav tau qhov hluav taws xob qis tshaj plaws thiab tam sim no dua li ib qho uas siv los ntsuas cov tshuab hluav taws xob high-voltage.
Qhov thib ob xav txog yog tag nrho qhov loj thiab qhov hnyav ntawm lub transformer. Nyob ntawm daim ntawv thov npaj rau kev sim transformer, koj yuav xav tau ib qho khoom siv uas compact thiab yooj yim rau kev thauj mus los lossis ib qho uas loj dua thiab muaj zog dua rau kev ntsuas siab.
Lwm qhov tseem ceeb uas yuav tsum nco ntsoov yog qhov zaus ntawm qhov tso zis hluav taws xob xav tau rau koj qhov kev sim. Cov kev sim ntsuas kev sib hloov ua haujlwm ntawm qhov zaus ntawm 50 lossis 60 Hz, tab sis cov cuab yeej tshwj xeeb yuav xav tau ntau zaus sib txawv los tsim cov qib siab uas xav tau thiab ua qhov kev ntsuam xyuas raug.
Nws tseem yog ib qho tseem ceeb uas yuav tau xaiv ib qho kev sim transformer los ntawm cov chaw tsim khoom muaj npe nrov npe hu ua cov khoom siv txhim khu kev qha thiab raug. Lub tshuab hluav taws xob tsim tau zoo thiab muaj txiaj ntsig zoo tuaj yeem txhim kho qhov raug thiab kev nyab xeeb ntawm koj qhov kev sim hi-pot, txo qhov kev pheej hmoo ntawm hluav taws xob poob lossis lwm yam xwm txheej txaus ntshai.
Test transformer muaj peev xwm xaiv
Cov mis rau kev txiav txim siab lub peev xwm Pn ntawm nominal test transformer:
Pn=kVn2WCt10-9
n- Nominal test transformer peev (kVA);
k - Kev nyab xeeb yam;
Vn- Cov txiaj ntsig zoo ntawm cov khoom tso zis siab voltage ntawm qhov ntsuas transformer (kV)
W - angular zaus, W=2πf, f yog qhov zaus ntawm qhov ntsuas hluav taws xob;
Ct-Tub Capacitance (PF)
Rau qhov sib txawv ntsuas voltages Vn, qhov tsim nyog kev nyab xeeb k raug xaiv. Thaum qhov ntsuas nominal voltage tsawg, tus nqi k tuaj yeem siab dua. Cov hauv qab no yog cov npe sib txawv ntawm qhov ntsuas hluav taws xob Vn, qhov kev xaiv kev nyab xeeb k tus nqi, rau kev siv:
Vn=50-100kV k=4;
Vn=150-300kV k=3
Thaum kawg, lub peev xwm ntawm koj qhov kev sim transformer yuav nyob ntawm ntau yam, suav nrog qhov voltage thiab tam sim no cov cai ntawm koj daim ntawv thov tshwj xeeb, qhov loj thiab qhov hnyav ntawm transformer, thiab qhov zaus ntawm cov zis voltage xav tau. Los ntawm kev ua tib zoo xav txog cov xwm txheej no thiab xaiv cov chaw tsim khoom lag luam txhim khu kev qha thiab muaj koob npe, koj tuaj yeem xyuas kom meej tias koj qhov kev xeem hi-pot yog qhov tseeb thiab nyab xeeb rau koj thiab koj cov neeg ua haujlwm.
