船舶电磁干扰抑制和电气接地

Ship Electromagnetic Interference Suppression and Electrical Grounding

随着船舶自动化程度的提高,越来越多的电力电子设备应用到船舶上。随之而来的是,无处不在的电磁干扰现象,小则引起设备工作不正常,严重时会使船舶操作性能降低,造成严重的事故。但在船舶电气设计与设备安装时,却往往忽视这些现象。分析了电气设备电磁干扰产生的原因,并结合船厂实际,对抑制船舶电气设备电磁干扰的方法进行了介绍和分析。

With the increasing levels of ship automation, more and more electrical equipments are applied on ship, which caused the phenomenon of electromagnetic interference. That can affect the proper functioning of equipment and probably affect the ship operation or even cause serious accidents. While the electromagnetic interference is frequently ignored when it is designed and installed. This paper analyzed the reason of electromagnetic interference, introduced how to prevent it on ship＇ s electrical equipment based on practice experience.
