VBI Caij nplooj ntoos hlav Actuating Mechanism
hauj lwm:
Qhov no VBI actuating mechanism yog rau VBI-12 nqus Circuit Court breaker yog ib hom ntawm sab hauv tsev high voltage Vcb, haum rau 3 theem AC,50 Hz, thiab nyob voltage ntawm 12kV, thiab thov nyob rau hauv qhov chaw nrog tawg ntawm txawv load thiab nquag ua hauj lwm raws li kev tiv thaiv thiab kev tswj chav tsev, xws li muaj thiab tsuas enterprise, fais fab nroj tsuag thiab transformer substations.
