CT PT Volt - Ampere Analyzer(tseem hu ua transformer volt mere tus cwj pwm los yog cov khoom siv kev zam rau hauv cov kev paub zoo ntawm cov kev hloov pauv (CT) thiab cov npe, tseem hu ua VT).
Kuaj Khoom thiab Lub Hom Phiaj:
CT:Lub hom phiaj tseem ceeb yog sim nws cov yam ntxwv zoo (volt ampere cov yam ntxwv), siv rau:
Tshawb xyuas seb CT ua tau raws li qhov uas yuav tsum muaj ntawm cov kev tiv thaiv theem (xws li 5P, 10p) lossis ntsuas qib (xws li 0.2, 0.5).
Xam cov hauv caug taw qhia voltage thiab saturation point ntawm CT.
Txheeb xyuas qhov ua tau zoo ntawm CT raws li kev ua txhaum tam sim no (saturation cov yam ntxwv tseem ceeb heev rau kev tiv thaiv).
Kev kuaj mob seb puas muaj qhov tsis xws luag xws li inter tig luv Circuit Court thiab hlau tub ntxhais hluas hauv CT.
PT / VT:Feem ntau yog xeem nws tsis muaj - Cov yam ntxwv zoo (muaj kev paub zoo), siv rau:
Txheeb xyuas qhov tseeb theem ntawm PT (xws li 0.2, 0.5).
Txheeb xyuas kev sib nqus lossis cov teeb meem rwb thaiv tsev nrog PT hlau tub ntxhais.
Ntsuas tsis muaj - ntim khoom tam sim no thiab poob.
Ceeb Toom Txog Kev Nyab Xeeb Kev Nyab Xeeb:Thaum ua Volt Ampere cov yam ntxwv kev kuaj, nws yog qhov tsim nyog tiag tiag kom ntseeg tau tias thawj sab ntawm lub CT yog qhib thiab tsis muaj tam sim no ntws los ntawm. Ntxiv rau txuas cov tester rau sab thib ob, txhua qhov sib txuas sab nraud (suav nrog cov xaim xaim hauv av) yuav tsum raug kaw. Ua txhaum txoj cai no yuav ua rau muaj hluav taws xob txaus ntshai, kev puas tsuaj, thiab yog tus kheej raug mob. Thaum PT kev sim, nws kuj yog qhov yuav tsum muaj los xyuas kom muaj kev nyab xeeb kev nyab xeeb ntawm thawj sab. Nruj dua rau kev tswj hwm kev nyab xeeb yog qhov yuav tsum tau ua thaum lub sijhawm ua haujlwm.
