Thaum nws los txog rau kev ntsuas hluav taws xob hluav taws xob, ib qho ntawm cov cuab yeej tseem ceeb tshaj plaws hauv cov kws tshaj lij lub arsenal yog Megohmmeter. Megohmmeter, tseem hu ua tus ntsuas hluav taws xob tiv thaiv hluav taws xob, yog tsim los ntsuas qhov tsis kam ntawm hluav taws xob rwb thaiv tsev. Qhov no yog qhov tseem ceeb vim tias cov rwb thaiv tsev zoo ua kom cov khoom siv hluav taws xob muaj kev nyab xeeb rau kev khiav lag luam thiab txo qhov kev pheej hmoo ntawm hluav taws xob poob lossis hluav taws.
Megohmmeter ua haujlwm los ntawm kev siv lub zog DC siab rau cov rwb thaiv tsev uas tau sim thiab ntsuas qhov tam sim no uas ntws los ntawm nws. Tus nqi ntawm qhov tsis kam mus rau qhov tam sim no qhia txog qhov xwm txheej ntawm cov rwb thaiv tsev thiab qhov yuav ua rau nws tawg hauv qab load.
Wuhan huayi fais fab fais fab tshuab yog lub chaw tsim khoom ntawm megohmeter, thiab koj tuaj yeem xaiv cov qauv sib txawv thiab hom megohmeters. GM-20KV muaj cov yam ntxwv hauv qab no.
1, muaj zog tiv thaiv kev cuam tshuam: muaj zog tiv thaiv hluav taws xob induction cuam tshuam muaj peev xwm, mus txog 2mA (50Hz), paub tias hloov mus rau 500kV substation yam tsis muaj kev cuam tshuam ntawm qhov chaw ntsuas ntawm 500kV loj transformer rwb thaiv tsev tsis kam;
2, luv luv Circuit Court tam sim no loj: luv luv Circuit Court tam sim no ntawm qhov ntsuas fais fab mov yog> 5mA, qhov siab tshaj plaws yog 15mA. Hloov mus rau qhov muaj peev xwm loj, loj inductance xeem;
3, kev ntsuas ntsuas qhov dav dav: los ntawm 0.5MΩ ~ 1999GΩ. Kev nyeem ntawv raug, siab daws teeb meem;
4, siab voltage tso zis ntau yam: muaj peev xwm xaiv 0.5, 1, 2.5, 5, 10, 20kV, kuj yuav smoothly kho los ntawm 0V tas mus li hloov mus rau qhov yuav tsum tau voltage;
5, lub suab thiab lub teeb ceeb toom: nrog lub sijhawm ua haujlwm, ceeb toom tus neeg siv kom sau, thiab txheeb xyuas qhov nqus piv thiab polarization Performance index ntawm cov khoom ntsuas;
6, siab zoo: cov khoom tseem ceeb yog tag nrho cov khoom tuaj txawv teb chaws los xyuas kom meej qhov ntsuas qhov tseeb;
7, yooj yim siv: kev siv cov chassis sib xyaw, me me, lub teeb-yuag, yooj yim nqa;
8, zoo nkauj tsos: siv cov ntaub ntawv muaj zog thiab abrasive, kom lub zuag qhia tag nrho kev ntxhib los mos ntawm cov twj paj nruag thiab kev pab lub neej ntev;
