Kev ntsuas tsis muaj load ntawm lub transformer yog ib qho kev ntsuam xyuas los ntsuas qhov tsis muaj load poob thiab tsis muaj load tam sim no ntawm lub transformer los ntawm kev siv lub ntsuas hluav taws xob ntawm cov ntsuas sine yoj ntsuas zaus los ntawm winding ntawm ob sab ntawm transformer, thiab lwm cov windings yog qhib-circuited.Qhov tsis muaj-load tam sim no yog qhia raws li qhov feem pua ntawm qhov ntsuas tsis muaj load tam sim no I0 rau qhov ntsuas tam sim no Ie, txhais tau tias yog IO.
HV HIPOT GDBR series transformer muaj peev xwm thiab tsis muaj load tester
Thaum muaj qhov sib txawv tseem ceeb ntawm tus nqi ntsuas los ntawm kev ntsuas thiab tus nqi tsim qauv, tus nqi ntawm lub Hoobkas, tus nqi ntawm tib hom transformer lossis tus nqi ua ntej kev kho dua, qhov laj thawj yuav tsum tau pom.
Qhov tsis muaj-load poob yog feem ntau hlau poob, uas yog, hysteresis poob thiab eddy tam sim no poob noj hauv cov tub ntxhais hlau.Thaum tsis muaj load, qhov excitation tam sim no ntws los ntawm thawj winding kuj ua rau tsis kam, uas tuaj yeem tsis quav ntsej yog tias qhov excitation tam sim no me me.Qhov tsis muaj-load poob thiab tsis muaj-load tam sim no nyob ntawm cov yam ntxwv xws li lub peev xwm ntawm lub tshuab hloov pauv, cov qauv ntawm cov tub ntxhais, kev tsim cov ntawv silicon steel thiab cov txheej txheem tsim khoom ntawm cov tub ntxhais.
Lub ntsiab yog vim li cas rau qhov nce ntawm tsis muaj load poob thiab tsis muaj load tam sim no yog: tsis zoo rwb thaiv tsev ntawm silicon steel los xij;luv luv Circuit Court ntawm ib feem ntawm silicon steel los xij;luv luv-circuit lem tsim los ntawm kev puas tsuaj rau lub rwb thaiv tsev ntawm cov tub ntxhais bolts los yog siab daim hlau, sab sauv yokes thiab lwm qhov chaw;Cov ntaub ntawv silicon steel yog xoob, thiab txawm tias muaj qhov sib txawv ntawm huab cua, uas ua rau muaj qhov sib nqus tsis sib haum (tsuas yog ua rau tsis muaj kev thauj khoom tam sim no);txoj kev sib nqus yog tsim los ntawm cov ntawv tuab silicon steel (tsis muaj kev thauj khoom nce thiab tsis muaj-load tam sim no txo);inferior silicon steel yog siv Pieces (ntau dua nyob rau hauv me me transformers);ntau yam winding tsis xws luag, suav nrog inter-tig luv luv Circuit Court, thaum uas tig mus ceg luv luv Circuit Court, sib txawv ntawm cov lem nyob rau hauv txhua yam thaum uas tig mus ceg, thiab incorrect ampere-tig acquisition.Tsis tas li ntawd, vim qhov tsis raug hauv av ntawm qhov sib nqus Circuit Court, thiab lwm yam, tsis muaj qhov poob thiab qhov nce tam sim no kuj yuav tshwm sim.Rau cov transformers me me thiab nruab nrab, qhov loj ntawm cov tub ntxhais seam tuaj yeem cuam tshuam qhov tsis muaj load tam sim no thaum lub sijhawm tsim khoom.
Thaum ua qhov kev sim tsis muaj kev thauj khoom ntawm lub tshuab hloov pauv, txhawm rau ua kom yooj yim rau kev xaiv cov cuab yeej thiab cov cuab yeej siv thiab ua kom muaj kev nyab xeeb ntawm qhov kev sim, cov cuab yeej thiab cov khoom siv hluav taws xob feem ntau txuas nrog rau sab qis, thiab sab siab-voltage. sab laug qhib.
Qhov ntsuas tsis muaj load yog ntsuas qhov tsis muaj load thiab tsis muaj load tam sim no nyob rau hauv qhov ntsuas voltage.Thaum lub sij hawm kuaj, sab high-voltage yog qhib, thiab sab qis-voltage yog pressurized.Qhov ntsuas hluav taws xob yog qhov ntsuas hluav taws xob ntawm sab qis-voltage.Qhov ntsuas hluav taws xob tsawg, thiab qhov ntsuas tam sim no yog ob peb feem pua ntawm cov ntsuas tam sim no.los yog txhiab.
Qhov ntsuas hluav taws xob ntawm qhov ntsuas tsis muaj hluav taws xob yog qhov ntsuas hluav taws xob ntawm sab qis-voltage, thiab qhov ntsuas tsis muaj hluav taws xob ntawm lub tshuab hluav taws xob feem ntau ntsuas qhov tsis muaj qhov poob.Tsis-load losses feem ntau yog hlau poob.Qhov loj ntawm cov hlau poob tuaj yeem suav tias yog kev ywj pheej ntawm qhov loj ntawm lub load, uas yog, qhov poob ntawm qhov tsis muaj load yog sib npaug rau cov hlau poob ntawm qhov load, tab sis qhov no yog hais txog qhov xwm txheej ntawm qhov ntsuas hluav taws xob.Yog hais tias qhov voltage deviates los ntawm tus nqi ntsuas, txij li cov hlau nplaum induction nyob rau hauv lub transformer core yog nyob rau hauv lub saturation seem ntawm magnetization nkhaus, tsis muaj load poob thiab tsis muaj load tam sim no yuav hloov sharply.Yog li, qhov ntsuas tsis muaj load yuav tsum tau nqa tawm ntawm qhov ntsuas hluav taws xob.
