稳恒电场发生器的研究与设计

摘要

The ship＇s underwater positioning,identification,protection and assessment is based on the electric field measurement.However,steady current electric field is essential to the adjustment of Electric field measurement equipment.In this paper,according to the current continuity principle and the laplace equation in a passive uniform medium,an electric field of steady current producer is designed,and influence of gas electrode reaction on electric field of steady current is analyzed.The fine adjustment of electric field of steady current is analyzed by a finite element program.How to shield the power line interference is discussed.%电场测量是舰船水下电场定位、识别、防护与评估的基础,而电场测量设备的校准则离不开稳恒电场,本文根据电流连续性定理和均匀无源介质中的的稳恒电场的拉普拉斯方程设计了一款稳恒电场发生器,分析了产生气体的金属电极反应对产生的稳恒电场的影响,并用有限元分析软件分析了通过活动电极微调稳恒电场的方法,讨论了如何实现外部工频干扰电场的屏蔽以及如何应用稳恒电场发生器校准电场测量设备。
