摘　　要：论文阐述了舰船极低频磁场特性的产生机理及防护技术,为了抑制舰船在海水中行驶时所产生的极低频电场信号,利用主动轴接地系统的电场防护方法,结合数字信号处理芯片,提出了抑制舰船极低频电场产生的改进型控制方案。This paper describes the characteristics of the ship ELF magnetic field generation mechanism and protection technology. In order to suppress the extremely low frequency electric signal when the ship traveling in seawater, generated by the use of electric drive shaft grounding system protection methods, combined with digital signal processing chip, im- proved control scheme is put forward to suppress the extremely low frequency electric field generated by the ship.

关 键 词：极低频电场 防护方法 控制方案
