Abstract：Gas-insulated switchgear （GIS） is widely used.To meet the requirements for the precision and accuracy offault location and fault type of GIS inteligent online monitoring systems inthe new era，a GISonline monitoring system was designed，and ultra-high frequency（UHF）signals were embedded in the detection system to improve analysis precision and accuracy. Multiple monitoring cabinets were configured in the GIS intelligent online monitoring system，which were integrated into the partial dischargeonline monitoring device.The workflowof the GIS intellient online monitoring system wasanalyzed，anda GIS intellgent online monitoring system with time diffrence positioning function was designed.Through the design and installation of the above-mentioned GIS intellgent online monitoring system，the GIS intelligent online monitoring platform of a certain project was monitored.The application resultsshow thatthedesignedGIS intellgent online monitoring systemcan realizereal-timeGISonline monitoring and accurately analyze the type of GIS partial discharge and the location of abnormal signals.
