The Impact

To reduce the impact of shaft-rate electric field (SRE) on the concealment of the ship, the SRE related ship electrical equivalent model is established, and the electrical properties are studied based on the analysis of the mechanism of SRE of the ship in this paper. The ship SRE real-time suppression is proposed based on the compensated negative potential and the real-time close-loop system for the ship SRE suppression is designed. The extremely low frequency electric field strength is reduced greatly, and the shaft-rate and its harmonics field are eliminated ultimately. Experimental results show that the ship SRE can be suppressed effectively by the system, and the concealment of the ship is enhanced.

The Impact

In order to reduce the impact of shaft-rate electric field (SRE) on the concealment of the ship, the factors that influence shaft-rate electric field are studied based on the analysis of its energy source. The ship electrical equivalent model is established by analyzing the structure of ship shafts, and on this basis, the electrical properties of the ship shafting is analyzed, laying the theoretical foundation for the study of shaft-rate electric field. It is shown that the bearing contact impedance changing is the important part of the ship shaft structure electricity analysis among the factors and its analysis is the base of research on shaft-rate electric field restrains technology.
