  • Protection relay device and power conversion system
    Patent number: 11557894
    Abstract: A protection relay device includes a housing and a fuse unit. The fuse unit includes a connection conductor, an input conductor connected to the connection conductor and receiving an external power, a fuse connected to the connection conductor, and an external device connection conductor connected to the fuse on a side opposite to the input conductor, and to which an external device is connected. A short-circuit induction conductor is provided on at least one of the input conductor on a side opposite to the fuse and the flapper portion, the short-circuit induction conductor protruding toward the other of the input conductor and the flapper portion.
