A SHAFT GENERATOR ARRANGEMENT OF A SHIP

摘要

A shaft generator arrangement of a ship according to the invention comprises a permanent magnet generator (1) to be arranged around a main shaft (2) of the ship, and a frequency transformer (5) arranged to transform voltage of the generator. The arrangement has also a generator breaker (7) between the generator (1) and the frequency transformer (5) through which the generator is connectable to the frequency transformer. The windings (1A) of the permanent magnet generator (1) are connected to a star point (9), and which generator comprises a star point breaker (10) between the windings (1A) and the star point (9).
