A Transformer Muaj Peev Xwm Muaj Peev Xwm \/ Tsis Muaj-Load Testeryog cov khoom siv ntau tshaj plaws siv rauKuaj cov kev ua tau zoo ntawm tus transformer nyob rau hauv tsis muaj-thauj thiab puv-thauj khoom (lossis ib nrab-thauj khoom) tej yamCov. Nws ntsuas xyuas cov hluav taws xob tsis zoo xws li muaj peev xwm, thau khoom poob, tsis muaj-thauj khoom poob, hluav taws xob kev tswj, thiab ua tau zoo.
Dab tsi yog transformer muaj peev xwm load \/ tsis muaj kev thauj khoom?
Tus kws ntsuas no ua ke sib txuas ntau cov kev sim ua ke rau hauv ib chav thiab siv rau:
Kev Ntsuas Cov Khoom Siv Hluav Taws Xob (Kva \/ MVA)
Kuaj tsis-thauj khoom poob thiab tam sim no
Kuaj cov khoom lag luam poob, impedance, thiab efficievy
Txheeb xyuas cov kev tswj hluav taws xob hauv qab thauj khoom
Hais txog kev ua tau zoo rau cov qauv
Nws yog feem ntau siv nyob rau hauvTransformer Raug Nroj Tsuag, Cov Khoom Siv Hluav Taws Xob, thiabCov chaw kuaj mob ntawm qhov chaw.
Lub Hom Phiaj ntawm Tester
Lub hom phiaj tseem ceeb yog:
Txiav txim siabMuaj peev xwm ntsuas muaj peev xwmntawm lub transformer
Txheeb xyuas tias nws ntsibTsim thiab Npe Cov Lus Qhia Tshwj Xeeb
Kuaj ntsuasZog EfficiencythiabKev ua tau zoo
Txheeb xyuasTxhaum windings, cov teeb meem tub ntxhais hluas sib nqus, lossis load tsis txaus
Nws ua haujlwm li cas
Tsis muaj-load sim:
Siv ntsuas hluav taws xob voltage rauthawj windingnrogThib ob qhib.
Ntsuas:
Tsis muaj-thauj khoom tam sim no (io)
Tsis muaj-load poob (tub ntxhais ploj, p₀)- Vim tias hysteresis thiab eddy dej hauv cov tub ntxhais.
Qhov no yuav pab ntsuasCov kev ua tau zoothiabMagnetization Zoo.
Kev ntsuas kev ntsuas (ntsuas luv luv):
Siv voltage rau kev ua haujlwm winding nrogThib ob sheed.
Ntsuas:
Puv-thauj khoom tam sim no (iFL)
Ntsaws poob (tooj liab ploj, pk)
Impedance (z)
Simulates kev ua haujlwm tiag tiag los ntsuasKev ua yeeb yam winding thiab kev ua kom sov.
Kev kwv yees peev:
Siv tam sim tam sim no thiab voltage nyeem los xam:
Muaj peev xwm (s) =3 ⋅v⋅i (rau ⋅ {}}}}}} =3 ⋅v⋅i (rau 3-} theem)
Pab kom paub meej tias tus hloov pauv tuaj yeem tswj hwm tusrated zognyob rau hauv kev cia siab load.
