Study on Linear Metal Particle Motion and Electrode-coating in DC GIL

The surface charge distribution and electric field force of linear metal particle in DC were studied, and effect of electrode coating on the lift force of linear particles was discussed. In order to study the experimental phenomenon of linear free conductor particle motion, the experimental device and observation system of free conductor particle are designed. Based on the micro transport equations of positive and negative ions, finite element simulation software was used to establish the linear particles with different cross-section shapes and the charge and lift force models of electrode coating particles under DC.
