Thaum kuaj cov rwb thaiv tsev ntawm lub transformer, xaiv cov qauv raws li qhov voltage theem ntawm transformer:
① Xaiv 10K qauv rau transformers nrog lub zog ntawm 220kV thiab siab dua;
② Xaiv tus qauv 5K rau 35-110kV fais fab transformer;
③ Xaiv 5K qauv rau 10-20kV faib transformers;
Thaum kuaj cov rwb thaiv tsev tiv thaiv ntawm lub tam sim no transformer, xaiv cov qauv:
HZJY-5KI qauv 6kV-220kV tam sim no transformer
GB{{0}}.0.3 Kev ntsuas ntawm rwb thaiv tsev tiv thaiv ntawm windings yuav tsum ua raws li cov cai hauv qab no:
1. Lub rwb thaiv tsev tiv thaiv ntawm thawj winding thiab theem nrab winding thiab lub casing, nrog rau ntawm txhua qhov thib ob winding thiab lub casing, yuav tsum tau ntsuas. Tus nqi rwb thaiv tsev tsis zoo yuav tsum tsis tsim nyog
Hauv qab 1000MQ;
Ntsuas qhov rwb thaiv tsev tiv thaiv ntawm cov thawj winding ntu ntawm lub tam sim no transformer, thiab cov rwb thaiv tsev tus nqi yuav tsum tsis txhob qis dua 1000MQ. Vim yog vim li cas cov txheej txheem, tsis muaj rwb thaiv tsev
Thaum ntsuas, nws tsis tas yuav ntsuas:
Ntsuas cov rwb thaiv tsev ntawm lub davhlau ya nyob twg screen ntawm lub capacitive tam sim no transformer thiab grounding davhlau ya nyob twg (N) ntawm lub voltage transformer rau lub plhaub (hauv av). Tus nqi rwb thaiv tsev tsis yog
Nws yuav tsum tsawg dua 1000MQ. Thaum lub rwb thaiv tsev tiv thaiv ntawm lub vijtsam kawg rau hauv av tsawg dua 1000MQ, nws cov tan yuav tsum ntsuas thiab tus nqi yuav tsum tsis pub tshaj 2%;
Lub 2500V megohmmeter yuav tsum tau siv los ntsuas kev tiv thaiv rwb thaiv tsev.
3. Thaum kuaj fais fab cables, xaiv raws li cov cable voltage theem:
Piv txwv li: 10kV cable HZJY-5KI HZ-3151
Rwb thaiv tsev tsis kam ntawm cov ntaub thaiv sab nrauv ntawm 35kV thiab hauv qab roj hmab insulated fais fab cables: 500V rwb thaiv tsev kuaj, rwb thaiv tsev tiv thaiv ib mais
Tus nqi Ntau dua lossis sib npaug rau 0.5MQ.
20kV cable HZJY-20KI
