Method for carrying out structure optimization on metal particle trap in GIS

The invention provides a method for carrying out structure optimization on a metal particle trap in a GIS (Geographic Information System). The method comprises the following steps: inputting structure parameters of a GIS, shape parameters of an insulator, and structure parameters and operation parameters of a metal particle trap, and obtaining a characteristic electric field of the bottom of the metal particle trap through a calculation method of the characteristic electric field of the bottom of the metal particle trap based on the input various parameters; obtaining the capture range of the metal particle trap through a calculation method of the capture range of the metal particle trap based on various input parameters; calculating the value of an objective function according to the characteristic electric field and the capture range; optimizing the calculation method of the capture range of the metal particle trap according to the objective function value obj, and obtaining the optimal structure parameter
