The invention discloses a steering power supply electricity taking method of an electric ship full-rotation propelling device, which is based on the full-rotation propelling device adopting a steering motor and a propelling motor, and the steering motor and the propelling motor are respectively connected with a steering frequency converter and a propelling frequency converter. The steering frequency converter and the propulsion frequency converter are connected with the direct-current main bus through the steering fuse and the propulsion fuse respectively, the steering frequency converter and the propulsion frequency converter form a common direct-current bus structure, when the direct-current main bus is powered on, the steering frequency converter and the propulsion frequency converter are powered on, and when the direct-current main bus is powered off, the steering frequency converter and the propulsion frequency converter are powered off. The steering is stopped when the steering fuse is fused, and the propulsion is stopped when the propulsion fuse is fused. Under the condition that the safety requirement of a ship is met, the design of the steering power supply of the full-rotation propelling device is simplified, the reliability and the efficiency are improved, and the system manufacturing cost is reduced.

    本发明公开了一种电动船全回转推进装置的转舵电源取电方法,基于采用转舵电机和推进电机的全回转推进装置,转舵电机和推进电机分别连接转舵变频器和推进变频器,转舵变频器和推进变频器分别通过转舵熔断器和推进熔断器连接直流主母线,转舵变频器与推进变频器形成共直流母线结构,当直流主母线有电时转舵变频器与推进变频器均有电,当直流主母线失电时转舵变频器与推进变频器均失电,转舵熔断器熔断时停止操舵,推进熔断器熔断时停止推进。本发明在满足船舶安全性要求的条件下简化了全回转推进装置转舵电源设计,提高了可靠性及效率,降低了系统造价。
