doi:10.3969/j.issn.1000-1093.2020.04.012

Abstract

Abstract: To decrease the ship's corrosion-related electric field, the effects of the current compensation technology on shaft-rate electric field and the active shaft ground technology(ASG) on the static electric field are analyzed, respectively. An integration method of decreasing both static electric field and shaft-rate electric field is proposed based on the correlation between current compensation and active shaft ground. In the proposed method, the compensation ASG current is regarded as the shaft current, and the ratio between compensation current and shaft current is used as the controlling parameter of current compensation, thus realizing the stealth of shaft-rate electric field firstly and then that of static electric field. Finally, a prototype of this new method is developed, and its effectiveness is examined by ship model experiment and sea trial, respectively. The results show that the proposed method is effective in decreasing both static electric field and shaft-rate electric field. Key
