3 QHOV NTAWM MEGGER INSULATION RESISTANCE TESTS
- SOJ-SIM LUB SIJ HAWM LOS NTAWM LUB TSEV KAWM NTAWV. Ib lub sij hawm luv luv los yog qhov chaw nyeem ntawv yog ua los ntawm kev txuas ib qho Megger rwb thaiv tsev tester hla cov rwb thaiv tsev uas tau sim. …
- TIME-RESISTANCE METHOD. …
- DIELECTRIC ABSORPTION RATIO.
Yuav ua li cas ntsuas Megger?
Megger tseem hu ua tus ntsuas hluav taws xobvim nws yog siv los ntsuas qhov rwb thaiv tsev ntawm cov kab hauv av, lub cev muaj zog windings, thiab lwm yam.
Yuav ua li cas yog hom rwb thaiv tsev tiv thaiv?
Txawm li cas los xij, cia peb tham tam sim no txog peb hom kev ntsuas kev tiv thaiv hluav taws xob siv Megger tester:
- Short-Time lossis Spot-Reading Test.
- Txoj Kev Ua Si Sijhawm.
- Dielectric Absorption Ratio.
Megger zoo yog dab tsi?
Txhua yam kev nyeem ntawv ntawm 2 megohms thiab 1000 megohms feem ntau suav tias yog kev nyeem ntawv zoo, tshwj tsis yog lwm yam teeb meem tau sau tseg. Txhua yam tsawg dua 2 megohms qhia tias muaj teeb meem rwb thaiv tsev.
Tus qauv Megger nyeem ntawv yog dab tsi?
Tig thiab nyeem tus ntsuas. Txhua yam nyeem nruab nrab ntawm 2 megohms thiab 1000 megohms feem ntau suav tias yog kev nyeem ntawv zoo, tshwj tsis yog lwm yam teeb meem tau sau tseg. Txhua yam tsawg dua 2 megohms qhia tias muaj teeb meem rwb thaiv tsev.
