稀疏金属栅格壁面微型静电屏蔽室的研究

Research on Micro Electrostatic Shielding Room with Sparse Metal Grid Wall

在科学试验中高压电会对周围设备造成严重干扰,而使用密闭的法拉第静电屏蔽笼会使试验人员无法观察和监测屏蔽笼内试验进展的情况。为了解决这两者之间的矛盾,针对用稀疏金属栅格作为壁面的微型静电屏蔽室进行了研究。首先利用简化模型从理论上分析了稀疏金属栅格的静电屏蔽安全范围,其次利用Comsol Multiphysics软件对理论分析的结果进行了仿真,最后通过试验验证了这种方法的是可行的。

High voltage is a common disturbing source in scientific experiments, however, when we use Faraday cage as electrostatic shielding,if the metal wall of the case is too dense,the experiment progressing could not be seen in the cage. To resolve the contradiction between them,a study of micro electrostatic shielding room with sparse metal grid wall was presented. Firstly,by using a simplified model,the safety scope of the electrostatic shielding room was analyzed theoretically. Secondly,the theoretical results were simulated with the software Comsol Mutiphysics on computer. Lastly,the feasibility of this method was verified by experiments.
