航天器表面充电到高静电位会导致静电放电(ESD),从而影响甚至破坏卫星电子器件。静电放电事件大多与各种表面材料之间的差异带电有关,因此研究不同表面材料在空间的充电电位对于控制航天器表面静电放电事件至关重要。本文介绍了用于测量表面电位的静电感应式电位监测器的工作原理,并且对探头部分设计参数的选取进行了数值模拟计算研究,用于设计参数的选取和优化。
Charging the surface of a spacecraft to a high static potential can cause Electrostatic Discharge (ESD), which affects or even destroys satellite electronics. Electrostatic discharge (ESD) events are mostly related to the difference in charge between various surface materials. Therefore, it is very important to study the charge potential of different surface materials in space to control the electrostatic discharge events on the surface of spacecraft. In this paper, the working principle of electrostatic induction potentiometer for measuring surface potential is introduced, and the selection of the design parameters of the probe part is studied by numerical simulation for the selection and optimization of the design parameters.
