Zusammenfassung:The invention discloses a marine redundancy auxiliary system which comprises a power station, and the power station is connected to a first direct-current bus through a working contactor and a high-speed fuse in sequence, and is successively connected with a daily auxiliary inverter, a sine-wave filter, a overcurrent protection circuit breaker , and an isolation transformer; an outlet of the isolation transformer is divided into two paths, one path is connected to a 380V busbar through a pre-magnetizing contactor, and the other path is connected to a 380V busbar through a working circuit breaker and a working contactor; the 380V busbar is connected with a 380V auxiliary load; the 380V busbar is connected with a 220V busbar through the overcurrent protection circuit breaker and a daily transformer, and the 220V busbar is connected with a 220V auxiliary load. The first direct-current bus is connected with a second direct-current bus through a bus section switch, and components the same as those on the first dir
