摘要：
The electrification of objects under HVdc transmission lines due to space ions generated by corona discharge may lead to pernicious consequences. The shielding effect of the metal wire mesh to the drifting ions is investigated. First, the model of the ion flow field with the presence of wire mesh is derived, and then the flux tracing method is used to simulate the interaction between the wire mesh and the drifting ions. Second, the indoor experiments about the shielding effect of the wire mesh to the ion flow field are presented, and measurement results are compared with simulation results, which validate the simulation model and method. Last, the relationship between mesh parameters and shielding effect is analyzed in detail, and some suggestions are proposed to improve the shielding effect of wire mesh.
