- Test lub hom phiaj:
1. Qhov kev ntsuam xyuas no tsom rau kev sim yog tias lub npav npav yuav tiv taus nws qhov hluav taws xob tiv thaiv tom qab tau teeb tsa hauv qhov chaw lossis nws yuav tawg thiab xyuas lub tshuab nqus tsev lub raj mis kev ncaj ncees, kuj los ntsuas qhov ntws tawm tam sim no thiab rwb thaiv tsev ntawm CB thiab hauv av.
- Cov khoom siv kuaj yuav tsum muaj:
1. AC HI-voltage txhaj tshuab
2. Earthing Qws lossis Ground Discharge stick (los nrog lub lauj kaub siab tester)
3. Megger 5KV DC Supply
- Mechanical thiab pom kev soj ntsuam:
1. Txhua txoj cai kev nyab xeeb yuav tsum tau muab coj los xav.
2. breaker tu thiab tu tsev.
3. Tshawb xyuas tag nrho cov khoom siv thauj khoom tshem tawm.
4. Tshawb xyuas hauv av rau switchgear hauv av tsheb npav.
5. Ua kom muaj kev tshem tawm kom txaus (nruab deb) ntawm qhov ntsuas hluav taws xob kawg thiab mus rau lwm yam khoom hauv av thiab lwm theem (tsis nyob hauv qhov kev sim) thiab nrog rau lwm yam khoom siv hluav taws xob los tiv thaiv flashover.
- Kuaj kev sib txuas thiab cov txheej txheem xeem
1. Test VCB withstand voltage: VCB yuav tsum nyob ze, txhaj voltage raws li tus nqi FAT.
• CEEB TOOM: Thaum peb ua qhov HIPOT Test rau ib theem, lwm theem ntxiv yuav tsum txuas nrog rau hauv av.
• Siv cov pas dej hauv av nrog cov hluav taws xob muaj zog kom tso tawm qhov hluav taws xob tawm ntawm qhov system tom qab txhua qhov Kev Ntsuas Siab.
2. Test CB withstands voltage: VCB yuav tsum qhib, txhaj voltage raws li tus nqi FAT.
3. Ntsuas cov rwb thaiv tsev tom qab qhov ntsuas hluav taws xob siab nrog CBs kaw thiab qhib qhov xwm txheej ces txhaj 5 KV rau 1 feeb tom qab ntawd sau tus nqi thiab sib piv nrog tus nqi ua ntej qhov ntsuas hluav taws xob siab.
CEEB TOOM:
Siv cov nplaum hauv av nrog cov hluav taws xob siab kom tso tawm qhov hluav taws xob los ntawm qhov system tom qab txhua qhov Kev Ntsuas Siab.
Wuhan huayi hluav taws xob fais fab muab HIPOT cov khoom siv rau kev sim VCB, muaj ntau yam qauv uas yuav tsum tau xaiv raws li koj qhov yuav tsum tau ua.
Muaj cov qauv 10KVA 100KV AC hipot kuaj teeb tuaj yeem ua tau raws li qhov kev xeem ib txwm. Muaj 3 hom kev sim transformers, hom qhuav, roj puv lossis SF6 roj puv.
Muaj 2 hom maub los, hom phau ntawv thiab hom tsis siv neeg.
