本发明涉及一种用于具有船用推进系统的海洋船舶(100)的阴极保护系统中的螺旋桨装置,该阴极保护系统包括具有正极端子(111;211)的直流电源(110;210)。该推进系统包括:至少一个传动系壳体(101;201),该至少一个传动系壳体至少部分浸没在水中;扭矩传递驱动轴(106;232、233),该扭矩传递驱动轴延伸出所述传动系壳体(101;201);以及至少一个螺旋桨(102、103;202、203),该至少一个螺旋桨安装在所述驱动轴(106;232、233)上。根据本发明,该至少一个螺旋桨(102、103;202、203)与其驱动轴(106;232、233)电绝缘。每个电绝缘的螺旋桨(102、103;202、203)电连接到滑环连接器(313a、313b),该滑环连接器(313a、313b)与正极端子(111;211)电连接。本发明还涉及设有这种螺旋桨装置的船舶。

    The invention relates to a propeller arrangement in a cathodic protection system for a marine vessel with a marine propulsion system, which cathodic protection system comprises a direct current power source with a positive terminal. The propulsion system comprises at least one driveline housing at least partially submerged in water; a torque transmitting drive shaft extending out of the driveline housing; and at least one propeller mounted on the drive shaft. According to the invention, the at least one propeller is electrically isolated from its drive shaft. Each electrically isolated propeller is electrically connected to a slip ring connector, which slip ring connector is in electrical connection with the positive terminal. The invention further relates to a vessel provided with such a propeller arrangement.
