Method, device and test platform for evaluating particle attachment degree of switch cabinet support member

The invention discloses a switch cabinet support member particle adhesion degree evaluation method and device and a test platform, and the method comprises the steps: spraying dirt in a switch cabinet, collecting dirt concentration measurement values at preset time intervals, and enabling a dirt concentration average value to be maintained in a dirt concentration threshold value range; under different pollution concentrations, comprehensive voltage-to-ground measured values of the multiple sets of supporting piece samples under the combined action of preset power frequency voltage and simulated lightning stroke voltage are obtained, and the preset power frequency voltage comprises a first preset amplitude; optimizing the initial model according to the comprehensive voltage-to-ground measurement value to obtain an optimized model; calculating a moment influence reference value and a voltage amplitude reference factor according to the simulated lightning stroke moment, the first preset amplitude and the compreh
