Yuav ua li cas tiv thaiv kev ua haujlwm tsis txaus ntseeg ntawm kev hloov pauv tam sim no?

1. Khoom siv khoom siv thiab kev teeb tsa
1. Qhov tsim nyog xaiv ntawm hloov pauv tam sim no
Piv xaiv xaiv: Xaiv cov feem tsim nyog raws li lub nra tiag tam sim no kom ntseeg tau tias qhov tam sim no tsis tshaj qhov Rated tam sim no ntawm cov kev ua haujlwm tam sim no. Piv txwv li, yog tias qhov tseem ceeb tam sim no ntawm cov ntsuas hluav taws xob yog 600a, koj tuaj yeem xaiv cov hloov pauv tam sim no nrog cov piv ntawm 600/5 lossis ntau li 800/5).
Qeb QIB: Xaiv cov qib raug uas ua tau raws li kev ntsuas ntsuas thiab kev tiv thaiv. Rau kev ntsuas lub hom phiaj, koj tuaj yeem xaiv qib {{0}}}. 2 lossis qib 0.5; Rau kev tiv thaiv lub hom phiaj, koj tuaj yeem xaiv qib 5p lossis 10p.
Cov ntsuas ntsuas (Xaiv cov ntsuas ntsuas ntsuas kom tsim nyog raws li cov tsheb theem nrab ntawm theem nrab kom ntseeg tau tias sab theem nrab thauj khoom yog nyob rau hauv ntau yam ntsuas.
2. Qhov kev teeb tsa raug
Sab theem nrab sab kaw: xyuas kom meej tias sab ob ntawm cov hloov pauv tam sim no yog ib txwm kaw thiab tsis tuaj yeem qhib. Yog tias yuav tsum tau muaj ib sab sab-theem nrab yog qhov yuav tsum tau ua, kab lus luv luv circuitic phaj lossis kab luv-circuit ci yuav tsum tau siv.
Kev sib txuas ntawm polarity: Txuas cov kev hloov pauv ntawm cov hloov pauv tam sim no kom ntseeg tau tias kev qhia tseem ceeb ntawm tus thawj coj ntawm polarity txo.
Txhim khu kev qha tau meej: xyuas kom meej tias sab ob yog zoo. Kev ua haujlwm tsis zoo yuav ua rau muaj teeb meem thiab kev nyab xeeb ntawm kev nyab xeeb.
2. Kev ua haujlwm thiab txij nkawm
1. Kev tshuaj xyuas ib txwm thiab txij nkawm
Appearance inspection: Regularly check the appearance of the current transformer to see if the terminal is loose, oxidized or corroded. Nyob rau tib lub sijhawm, tshuaj xyuas seb puas muaj qhov chaw so thaiv kev puas tsuaj, hnub nyoog lossis qhuav.
Kev tshuaj xyuas hluav taws xob kev tshuaj xyuas: ua kom nruj thiab ua kom nruj txhua qhov kev sib txuas hauv lub voj voog kom ntseeg tau tias kev ntseeg tau ntawm kev sib txuas hluav taws xob.
Rwb thaiv tsev tiv thaiv: Nquag siv ib qho melohmeter ntsuas cov rwb thaiv tsev hluav taws xob tiv thaiv cov txheej txheem theem siab theem nrab kom ntseeg tau tias nws ua tau raws tus qauv.
Kev Ntsuas Cov: Under Rated tam sim no, ntsuas qhov tiag tiag load ntawm theem nrab Circuit Court kom ntseeg tau tias nws tsis tshaj li qhov ntsuas hluav taws xob.
2. Pab tiv thaiv theem nrab ntu qhib Circuit Court
Thaum lub sijhawm ua haujlwm, nws yog nruj me ntsis txwv tsis pub qhib sab nraud. Yog tias kev saib xyuas lossis kho dua tshiab ntawm sab nraud yog qhov yuav tsum tau, thawj sab yuav tsum tau muab lub zog ua ntej.
3. Kev saib xyuas ib puag ncig
Xyuas kom meej tias kev ua haujlwm ntawm cov kev ua haujlwm tam sim no ua tau zoo li cov kev xav tau thiab tsis txhob muaj mob xws li xws li cov av noo lossis cov tshuaj corrosion siab. Yog tias qhov kev ua haujlwm ua haujlwm kub dhau heev, cov cua sov so lossis ua pa tawm tau ntsia tau.
III. Teeb thiab Debugging ntawm cov khoom tiv thaiv
1. Teem cov khoom tiv thaiv
Raws li cov yam ntxwv ntawm tus hloov pauv tam sim no, qhov kev txiav txim tus nqi thiab ncua ntawm cov khoom tiv thaiv kev tiv thaiv yuav tsum tsim nyog. Piv txwv li, rau overcurrent tiv thaiv cov cuab yeej tiv thaiv, qhov tsim nyog tau ua tiav qhov pib yuav tsum tau teeb tsa raws li qhov ntsuas uas muaj rated tam sim no thiab kev hloov pauv ntawm cov hloov pauv tam sim no.
Rau cov khoom siv tiv thaiv sib txawv, qhov tsim nyog sib txawv ntawm qhov pib tau tsim raws li cov yam ntxwv ua yuam kev ntawm tus hloov pauv tam sim no.
2. Debugging ntawm cov khoom tiv thaiv
Tom qab kev teeb tsa kev tiv thaiv kom ntseeg tau tias nws tuaj yeem teb cov teeb liab tam sim no los ntawm cov hloov pauv tam sim no. Thaum debugging, txawv ua txhaum cov neeg tuaj yeem tuaj yeem simulated los xyuas seb qhov kev txiav txim ntawm cov cuab yeej tiv thaiv yog qhov tseeb.
IV. Lwm yam kev ntsuas
1. Siv anti-saturation hloov pauv
Hauv qee lub sijhawm tshwj xeeb, hloov pauv tam sim no nrog kev tawm tsam cov yam ntxwv muaj zog, xws li hluav taws xob hloov pauv tau, tuaj yeem siv. Cov kev hloov pauv no tuaj yeem ua kom cov khoom siv ruaj khov nyob rau hauv nyob rau hauv cov dej ntws loj thiab txo qis.
2. Nruab cov kev tiv thaiv kev tiv thaiv
Nruab cov khoom siv kev tiv thaiv ntau yam nyob rau sab nraud ntawm qhov hloov pauv thib ob ntawm lub sijhawm tam sim no, thiab txiav lub zog hluav taws xob nyob rau lub sijhawm thaum lub sijhawm thib ob tshaj li tus nqi. Qhov no tuaj yeem tiv thaiv kev ua haujlwm tsis zoo los ntawm cov sab nraud dhau ntawm cov sab nraud dhau.
3. Cov ntaub ntawv txij nkawm
Tom qab txhua qhov kev tshuaj xyuas thiab kev saib xyuas thiab kev saib xyuas, cov ntsiab lus txij nkawm, kuaj ntsuas thiab kho cov ntsuas yuav tsum tau sau cia kom meej. Qhov no pab txhawm rau txhawm rau paub cov teeb meem muaj peev xwm nyob hauv lub sijhawm thiab coj kev ntsuas tsim nyog.
