The invention discloses an on-line intelligent monitoring module for intelligent
transformer substation GISs, which comprises an SF6 monitoring function module, a circuit
beaker monitoring function module, a capacitive
equipment monitoring function modules for mutual inductors and the like, a
lightning arrester monitoring function module, a
station level communication function module and a human-
machine interface function module. By means of the function modules, the on-line intelligent monitoring module for intelligent
transformer substation GISs can monitor the
gas insulation condition in a gas insulated
metal-enclosed
switchgear (GIS) and the operating condition of the primary equipment of each power
system on line, consequently, power
system operation maintainers can fully know the operating state of the GIS in real time and accordingly arrange the operation and maintenance time of the equipment, the safety of the operation of the GIS is enhanced, the
safe operation of a
power grid is effectively guaranteed, moreover, the maintenance method for the GIS is changed from the conventional scheduled maintenance to state maintenance, the equipment maintenance cost is effectively reduced, and the benefit of a
power grid operation maintenance enterprise is increased.
