Parameterization design checking method for double-fracture disconnecting switch for GIS (Gas Insulated Switchgear) of electric power system

The invention discloses a parameterized design checking method for a double-fracture disconnecting switch for a power system GIS. The parameterized design checking method comprises the following steps: establishing an initial 3D model of the double-fracture disconnecting switch; parameterizing a to-be-adjusted part in the initial 3D model and assigning an initial value; establishing a simplified simulation model in a target field for the parameterized initial 3D model; establishing a parameterized mapping relationship between the parameterized initial 3D model and the simplified simulation model, and constructing a parameterized design simulation tool; obtaining target values of to-be-adjusted partial parameters input by a user through a parameterization design simulation tool, adjusting the to-be-adjusted partial parameters in the initial 3D model and the simplified simulation model to obtain an intermediate 3D model and an intermediate simplified simulation model, performing automatic simulation on the inte
