The utility model discloses a relay for a remote-control automatic transferring device, which has the characteristics that the relay is connected between an automatic transferring loop and a master control system; the relay comprises a relay control module, an intermediate control module, a switch module, a feedback module and a power supply module, wherein the intermediate control module, the switch module and the feedback module are respectively in circuit connection with the relay control module; and the power supply module is in circuit connection with the relay control module and the intermediate control module respectively. The relay is connected with the remote master control system by an optical fiber communication system so as to realize remote-control transferring accurately and quickly, therefore, the system not only provides the remote-control transferring function but also displays a remote-control transferring state, an automatic transferring running state and a local/remote position state, thereby greatly reducing the workload of the running and the operation, so that the dispatching management personnel can quickly treat the faults of power grids directly by the remote-control automatic transferring in a main dispatching station.
