<p>PURPOSE:To automatically and readily detect the melting of a fuse by inputting and displaying a voltage presented in the primary coil through the secondary coil and a signal transmitted to a display unit when the fuse of a rectifier is melted. CONSTITUTION:A rotary transformer 8 which rotates together with a rotor is provided in a rotor of a synchronous machine. The primary coils 9 of the same number as that of the fuses of a rectifier are wound in parallel on a core of the transformer 8. The both ends of the coils 9 are connected to both ends of a fuse 6n. The output of the coil 11 of the transformer 8 is inputted through signal transmitting means 12 made of a transmitter 14 and a receiver 15 to a display unit 16.</p> |
