Megger Tus Nqi Ntawm Kev Tshaj Tawm Transformer

Fais fab transformers yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob. Cov transformers no nqis qis hluav taws xob los ntawm cov kab sib txuas mus rau qhov hluav taws xob qis uas tsim nyog rau kev faib khoom hauv zej zog lossis ib lub tsev. Ntsuas cov rwb thaiv tsev tiv thaiv ntawm cov transformers, uas tau hais nyob rau hauv megohms, yog ib qho tseem ceeb ntawm kev saib xyuas thiab kev ntsuam xyuas tsis tu ncua.
Lub megger tus nqi ntawm ib qho kev faib transformer qhia txog kev rwb thaiv tsev ntawm cov transformer windings thiab lub tank transformer. Qhov siab dua tus nqi megger, qhov zoo dua cov rwb thaiv tsev tiv thaiv thiab qis dua qhov kev pheej hmoo ntawm hluav taws xob tsis raug. Tsis tas li ntawd, siab megger qhov tseem ceeb qhia tau tias muaj peev xwm rau lub neej ntev dua rau cov transformers no.
Kev ntsuam xyuas tsis tu ncua ntawm transformers yog qhov tseem ceeb los xyuas kom meej tias ob qho tib si kev nyab xeeb thiab kev ua haujlwm zoo ntawm cov tshuab xa khoom. Megger qhov tseem ceeb tsim ib feem tseem ceeb ntawm qhov kev sim no thiab feem ntau yog ntsuas los ntawm kev ntsuas qhov ntsuas hluav taws xob siab hu ua megohmmeter, lossis "megger" luv luv. Cov cuab yeej no siv qhov hluav taws xob siab, feem ntau nyob ib ncig ntawm 500 mus rau 1, 000 volts, rau lub transformer winding rwb thaiv tsev thiab ntsuas qhov tshwm sim tam sim no. Kev ntsuas yog siv los ntsuas seb puas muaj kev puas tsuaj ntawm cov rwb thaiv tsev tau tshwm sim thiab txheeb xyuas qhov muaj feem cuam tshuam txog kev nyab xeeb.
Ntau yam sib txawv tuaj yeem ua rau rwb thaiv tsev degradation nyob rau lub sijhawm, nrog rau ib puag ncig, hnub nyoog, thiab kev ntxhov siab. Kev ntsuam xyuas tsis tu ncua siv lub megger tuaj yeem pab pom cov cim qhia ntxov ntawm cov teeb meem thiab tso cai rau kev kho lossis kho kom tsim nyog kom tsis txhob muaj teeb meem loj tshwm sim.
Hauv cov ntsiab lus, tus nqi megger ntawm kev faib khoom transformer yog ib qho kev ntsuas tseem ceeb uas qhia txog kev tiv thaiv kev tiv thaiv ntawm transformer windings thiab lub tank transformer. Kev ntsuam xyuas tsis tu ncua yog tsim nyog los xyuas kom meej tias ob qho tib si kev nyab xeeb thiab kev ua haujlwm zoo ntawm cov tshuab xa khoom, thiab tus nqi megger siab qhia tau tias muaj kev tiv thaiv zoo dua thiab kev ua haujlwm ntev ntawm kev hloov pauv.
