Kev siv ntawm Isolator Hloov
Ib qho insulator yog ib hom detaching hloov uas ua haujlwm nyob rau hauv cov xwm txheej ntawm off-loading.Nws cais qhov Circuit Court uas qhov yuam kev tshwm sim los ntawm lub hwj chim mov.Isolators muaj feem xyuam rau cov khoom siv hluav taws xob siab xws li transformers.Lub luag haujlwm tseem ceeb ntawm Isolator yog, nws thaiv cov teeb liab DC & tso cai rau cov teeb liab AC ntws.
Cov ntawv thov ntawm Isolators koom nrog cov khoom siv hluav taws xob siab xws li transformers.
Cov no muaj kev tiv thaiv nrog lub kaw lus kaw rau sab nraud lossis nrog lub xauv kom tsis txhob siv kev sib tsoo.
Isolator nyob rau hauv Substation: Thaum muaj kev txhaum tshwm sim nyob rau hauv lub substation, ces tus isolator txiav tawm ib feem ntawm lub substation.
Thaum muaj kev txhaum tshwm sim hauv ib lub chaw nres tsheb, tus cais tawm txiav tawm ib feem ntawm lub substation.Lwm lub cuab yeej ua haujlwm yam tsis muaj kev cuam tshuam.
Lub Circuit Court breaker yog zoo li MCB lossis ACB uas mus rau qhov ua tiav yog tias muaj qhov yuam kev tshwm sim
Yog li, qhov no yog txhua yam hais txog lub ntsiab lus ntawm cov hluav taws xob cais tawm.Cov yam ntxwv ntawm lub tshuab cais tawm no suav nrog nws yog ib qho khoom siv offload, ua haujlwm manually, De-energize lub Circuit Court, tag nrho kev sib cais rau kev ruaj ntseg txij nkawm, suav nrog lub ntsuas phoo, thiab lwm yam.
