摘　　要：研究导电微粒的荷电运动特性对治理气体绝缘开关设备中的导电微粒缺陷意义重大,目前采用数值模拟对微粒荷电运动研究的方法较少,且局限于欧拉法模拟。鉴于以上的问题,提出了一种应用离散元计算微粒运动的新策略,通过对比实验和算例的数据验证算法的准确性,并成功模拟了多个球形微粒/粉尘和线形微粒的运动,证明了该算法的应用优势与进一步的开发价值和潜力。The study of charge motion characteristic of conductive particle is of great significance for the treatment of conductive particle defect in gas insulated switchgear.At present the method of studying charge motion of particle with numerical simulation is less and is only limited to Eulerian simulation.In view of the above problems,a kind of new strategy to calculate the motion of particles based on discrete element method is proposed.The correctness of the algorithm is verified by comparing the results of experiments and calculation data,the motions of multiple spherical particles/dust and linear particles have been successfully simulated as well.The application advantage of the algo-rithm and the further development value and potential are proved.
