【摘要】 普通静电探测极板是全向接收的,任何方向的静电目标都会对其产生影响.为了避免其它电场的干扰并使探测极板具有一定的方向性,引入了接地屏蔽的方案,使实现对静电体目标局部静电信息的探测成为可能.通过理论分析、有限元仿真以及试验研究,证明了该方案的可行性,为后期根据带电目标的形状大小和带电量等实际情况进行探测单元的敷设提供了理论依据.更多还原

【Abstract】 The currently used electrostatic detector is omni-directional in receiving information ofelectrostatic target and will be impacted by an electrostatic object in any direction.To provide thedetection electrode with directional property as well as to prevent the disturbance from the electricfields in the other directions,an earth-shield detection unit is introduced in the detection system.It hasbeen proved that it is possible to detect a special part of an electrostatic target using this system.Byusing the method of formula analysis,finite element emulation and prototype test,a principle has beenprovided in designing the detection unit practically according to the parameters of target in the future.更多还原
