摘要: 静电场仪的精确校准对提高卫星在轨电场探测精度、保障卫星安全发射升空、精确预测雷电等具有重要意义。针对电场仪校准的需要,设计了平行极板电容式静态电场仪校准装置。利用三维电磁场仿真软件CST对标准静电场发生装置进行数值仿真,研究了校准箱内部及边缘处的静电场分布特点,分析标准极板直径和间距对边缘效应的影响,结合极板平行度对电场均匀性的影响分析,确定了校准过程中电场仪探头的最佳位置,实现静电场仪校准装置的最优化设计。

Abstract: The accurate calibration of the electrostatic field tester is of great significance for improving the detection precision of the space plasma field, ensuring the safe launch of the satellite, and accurately predicting the lightning and so on. Based on parallel plate capacitor, a calibration device was designed for the calibration of the electric field instrument. The standard electrostatic field generator was simulated by three-dimensional electromagnetic simulation software CST, the field distribution of inside and edge of calibration box was studied and the influence of the standard plate diameter and spacing on the edge effect was analyzed. Based on influence of the plate parallelism on the electric field uniformity, the best location of the electric field probe was determined, and the optimal design of calibration device was realized.
