Data storage method and system of GIS equipment partial discharge on-line monitoring system

The invention provides a data storage method and system of a GIS equipment partial discharge online monitoring system. The data storage method comprises the following steps: acquiring partial discharge signals and basic characteristic parameters of to-be-detected GIS equipment in real time, and storing the partial discharge signals and the basic characteristic parameters in a GIS partial discharge real-time data database; acquiring partial discharge signals and basic characteristic parameters of the GIS equipment at the current moment from the GIS partial discharge real-time data database according to a set time period, and storing the partial discharge signals and the basic characteristic parameters in a historical data database in a set time period; at the hourly moment, screening the most representative stroke corresponding to the hourly moment in the previous hour from the GIS partial discharge real-time data database, and storing the most representative stroke in the one-hour historical data database; 24
